```
+
+### Structured stream-json mode
+
+For programmatic integrations, Qwen Code supports structured JSON Lines input and output:
+
+- `--output-format stream-json` switches stdout to emit Claude-compatible envelopes (`user`, `assistant`, `result`, etc.).
+- `--input-format stream-json` lets you pipe newline-delimited JSON requests into stdin (e.g., control requests and user messages).
+- `--include-partial-messages` enables incremental `stream_event` deltas alongside the final assistant message.
+
+Example one-shot invocation:
+
+```bash
+echo '{"type":"user","message":{"content":"List supported flags"}}' \
+ | qwen --input-format stream-json --output-format stream-json
+```
+
+When run in this mode, every stdout line is a standalone JSON object you can parse reliably. Control responses (for example, acknowledging `control_request.initialize`) are also written using the same envelope schema.
+
+To keep a session open for multiple messages, omit `--prompt` and keep stdin open (for example, by running the CLI directly and typing JSON lines):
+
+```bash
+npm run stream-json-session
+```
+
+The process will remain active until EOF (`Ctrl+D`) or an explicit `control_request.interrupt`, making it suitable for SDK transports that maintain a persistent subprocess connection.
+
+The repository also provides a minimal Python client sample at
+`docs/examples/stream-json/simple_stream_json_client.py`. The script is adapted
+from `third-party/anthropics/claude-agent-sdk-python/examples/quick_start.py`
+and illustrates how to drive the session lifecycle with `control_request`, while
+showcasing a short multi-turn exchange (sending several `user` messages in a
+row):
+
+```bash
+python docs/examples/stream-json/simple_stream_json_client.py
+```
+
+Each log entry is separated with `------` and prefixed with `[client]` or `[cli]`
+to make debugging the JSON stream easier.

+# Stream JSON Interaction Example
+
+This example demonstrates how to drive the Qwen Code CLI directly via the JSON Lines protocol and provides a mock SDK client script to facilitate integration testing.
+
+## Prerequisites
+
+- `qwen code` is installed locally and ready to run (or run `npx tsx packages/cli/index.ts` inside the repo).
+- It is recommended to enable `--include-partial-messages` to experience incremental events.
+
+## Quick CLI Walkthrough
+
+1. Prepare an input stream (write it to `examples/stream-json/request.jsonl`):
+
+ ```bash
+ cat <<'EOF' > docs/examples/stream-json/request.jsonl
+ {"type":"control_request","request_id":"req-init-1","request":{"subtype":"initialize","hooks":null}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请阅读 README.md 并总结三个关键特性。"}]}}
+ {"type":"control_request","request_id":"req-interrupt-1","request":{"subtype":"interrupt"}}
+ EOF
+ ```
+
+2. Run the CLI and pipe the JSONL into standard input. Inside the repo, `npm run qwen` is recommended (parameters for the CLI itself go after `--`):
+
+ ```bash
+ npm run qwen -- \
+ --input-format stream-json \
+ --output-format stream-json \
+ --include-partial-messages \
+ --model glm-4.6 \
+ < docs/examples/stream-json/request.jsonl
+ ```
+
+3. Observe standard output: when the CLI initializes successfully, it prints `system/init`, `control_response`, and `stream_event` entries containing `thinking_delta` and `text_delta`, and finally ends with a `result` event.
+
+> Note: If the CLI emits events like `control_request.can_use_tool`, the caller must promptly write back a `control_response`; otherwise, the process waits for the acknowledgement.
+
+## Mock SDK Script
+
+- Location: `docs/examples/stream-json/simple_stream_json_client.py`
+- Functionality: launches a CLI subprocess, automatically completes the `initialize` handshake, sends user messages, and provides sample responses for control requests such as `can_use_tool` and `hook_callback`. Once `result` is received, the script ends the session with an `interrupt`.
+
+Usage example:
+
+```bash
+python docs/examples/stream-json/simple_stream_json_client.py
+```
+
+By default the script launches the CLI via `npm run qwen -- …`. To replace the command, set the `QWEN_STREAM_JSON_COMMAND` environment variable, for example:
+
+```bash
+# export QWEN_STREAM_JSON_COMMAND="npm run qwen -- --input-format stream-json --output-format stream-json --include-partial-messages --model glm-4.6"
+export QWEN_STREAM_JSON_COMMAND="npm run qwen -- --input-format stream-json --output-format stream-json --include-partial-messages"
+python docs/examples/stream-json/simple_stream_json_client.py
+```
+
+The script exposes a `StreamJsonClient` class that can be customized with `StreamJsonClientOptions` to define commands, initialization requests, user messages, and control handlers. For example:
+
+```python
+import asyncio
+import sys
+
+sys.path.append("docs/examples/stream-json")
+from simple_stream_json_client import StreamJsonClient, StreamJsonClientOptions
+
+options = StreamJsonClientOptions(
+ command=["npm", "run", "qwen", "--", "--input-format", "stream-json", "--output-format", "stream-json"],
+ user_messages=[
+ {
+ "type": "user",
+ "message": {
+ "role": "user",
+ "content": [{"type": "text", "text": "举例说明 stream-json 协议用途"}],
+ },
+ }
+ ],
+ extra_handlers={
+ # Reject sensitive tools
+ "can_use_tool": lambda client, request_id, payload: client.send_control_response(
+ request_id,
+ success=True,
+ response={"behavior": "deny", "message": "demo client blocks all tools"},
+ ),
+ },
+)
+
+client = StreamJsonClient(options)
+asyncio.run(client.run())
+```
+
+## Automated Tests
+
+New unit tests validate the Stream JSON functionality. Run them with:
+
+```bash
+npx vitest run \
+ packages/cli/src/streamJson/writer.test.ts \
+ packages/cli/src/streamJson/session.test.ts \
+ packages/cli/src/nonInteractiveCli.test.ts
+```
+
+The tests cover:
+- `system/init` events and session metadata
+- Incremental messages (`thinking_delta`, `input_json_delta`, etc.)
+- `usage` and `duration_api_ms` fields in the `result` event
+- Control request bridging logic for `can_use_tool`
+
+Following these steps quickly verifies the Stream JSON protocol’s output and control-channel behavior in the CLI.
+
+### Sample Run Log (Excerpt)
+
+The table below selects key log entries from the script run and annotates the showcased capabilities:
+
+| Log Snippet | Description |
+| --- | --- |
+| `{"type":"control_response","request_id":"demo-init","success":true,...}`
`{"type":"system","subtype":"init",...}` | Script writes back `initialize`, and the CLI outputs session metadata in the `system/init` event (control channel + system event).
+| `{"type":"user","message":{"role":"user","content":"请阅读 README.md..."}}` | The client sends a `user` message to trigger a single-turn session.
+| `{"type":"stream_event","event":{"type":"message_start",...}}`
`{"type":"stream_event","event":{"type":"content_block_delta","delta":{"type":"text_delta","text":"..."}}}`
`{"type":"stream_event","event":{"type":"content_block_delta","delta":{"type":"input_json_delta",...}}}` | Incremental event streaming: text `text_delta` and tool input `input_json_delta`.
+| `{"type":"assistant","message":{"content":[{"type":"tool_use",...}]}}`
`{"type":"user","message":{"content":[{"type":"tool_result",...}]},...}` | The CLI initiates a tool call; the script writes back `tool_result`, demonstrating bridging for `can_use_tool` and tool-result propagation.
+| Continuous `content_block_delta` entries printing the README summary
`{"type":"assistant","message":{"content":[{"type":"text","text":"..."}]}}` | Incremental reasoning/text events align with the final complete `assistant` message.
+| `{"type":"result","subtype":"session_summary","duration_api_ms":..., ...}` | The `result` event includes statistics such as `duration_api_ms` and `num_turns`.
+| `{"type":"control_response","request_id":"demo-interrupt","success":true,...}` | The script sends an `interrupt` to conclude, and the CLI returns a success response.
+
+## Manual Verification Guide
+
+Use the following commands to manually check that the core capabilities introduced in this implementation are present:
+
+1. **Initialization and Incremental Events** (verify that the `system/init` and `stream_event` lifecycle matches the Claude protocol)
+ ```bash
+ npm run qwen -- \
+ --input-format stream-json \
+ --output-format stream-json \
+ --include-partial-messages \
+ --model glm-4.6 \
+ < docs/examples/stream-json/request.jsonl
+ ```
+ Expected output: initialization includes the complete `system/init` fields; during the assistant response, `message_start`, `content_block_start/delta/stop`, and `message_stop` events appear.
+
+2. **Real-Time Control Channel** (verify advanced subtypes like `can_use_tool` and `hook_callback`)
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ # Enter sequentially:
+ {"type":"control_request","request_id":"req-init","request":{"subtype":"initialize"}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请执行 ls"}]}}
+ ```
+ Expected output: the CLI responds to the initialization request with `control_response.success`. When a tool invocation is triggered, it sends `control_request.can_use_tool`, and hook acknowledgements surface as `system hook_callback` messages.
+
+3. **MCP Message Bridging** (verify `mcp_message` passthrough)
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ {"type":"control_request","request_id":"req-mcp","request":{"subtype":"mcp_message","server_name":"default","message":{"jsonrpc":"2.0","id":"1","method":"tools/list"}}}
+ ```
+ Expected output: `control_response.success` contains `mcp_response.result.tools` listing the registered MCP tools. If MCP is not configured, the structured fields in `control_response.error` can be inspected instead.
+
+4. **Tool Result Linking** (verify `tool_result` carrying and `parent_tool_use_id`)
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ {"type":"user","message":{"content":[{"type":"tool_result","tool_use_id":"demo-tool","content":[{"type":"text","text":"手动工具结果"}]}]},"parent_tool_use_id":"demo-tool"}
+ ```
+ Expected output: during the subsequent `runNonInteractive` call the CLI reads this `tool_result`, continues the dialog when necessary, and suppresses redundant user echoes.
+
+These manual steps cover the advanced control requests, system initialization fields, incremental event completion, user-envelope extensions, and error semantics introduced by the remaining OpenSpec tasks.
+
+## Automated Verification Script
+
+To execute all of the above control-channel scenarios at once, run:
+
+```bash
+python docs/examples/stream-json/validate_stream_json_cli.py
+```
+
+The script automatically launches `qwen code`, triggers events such as `initialize`, `hook_callback`, `can_use_tool`, and `mcp_message` in sequence, prints every request/response JSON line in real time, and finally summarizes the pass/fail status of each assertion in a table. Adjust behavior with these environment variables:
+
+- `QWEN_STREAM_JSON_COMMAND`: override the CLI launch command.
+- `STREAM_JSON_VALIDATE_VERBOSE=0`: set to `0` to suppress line-by-line logging.
+- `STREAM_JSON_VALIDATE_PROMPT=1`: enable the additional “user prompt triggers tool invocation” scenario (requires a usable model or proxy credentials).
+- `STREAM_JSON_VALIDATE_TOOL_RESULT=1`: enable the additional scenario for the `tool_result + parent_tool_use_id` flow.

+# Stream JSON 交互示例
+
+本示例展示如何直接以 JSON Lines 协议驱动 Qwen Code CLI，并提供一个伪 SDK 客户端脚本，方便对接测试。
+
+## 先决条件
+
+- 本地已安装并可执行 `qwen code`（或在仓库内通过 `npx tsx packages/cli/index.ts` 运行）。
+- 建议使用 `--include-partial-messages` 以体验增量事件。
+
+## CLI 快速体验
+
+1. 准备一份输入流（写入 `docs/examples/stream-json/request.jsonl`）：
+
+ ```bash
+ cat <<'EOF' > docs/examples/stream-json/request.jsonl
+ {"type":"control_request","request_id":"req-init-1","request":{"subtype":"initialize","hooks":null}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请阅读 README.md 并总结三个关键特性。"}]}}
+ EOF
+ ```
+
+2. 运行 CLI，并使用 `cat … -` 方式保留标准输入，便于后续继续发送控制消息或工具回执。仓库内推荐通过 `npm run qwen` 启动（注意 `--` 之后才是 CLI 自身参数）：
+
+ ```bash
+ cat docs/examples/stream-json/request.jsonl - | \
+ npm run qwen -- \
+ --input-format stream-json \
+ --output-format stream-json \
+ --include-partial-messages \
+ --model glm-4.6
+ ```
+
+ 日志请看 @./logs/1.log
+
+3. 观察标准输出：当 CLI 初始化成功时会输出 `system/init`、`control_response` 以及含 `thinking_delta`、`text_delta` 的 `stream_event`，最后以 `result` 事件结束。
+
+ 若需要在会话结束后主动终止 CLI，可在上一步命令的终端中手动输入：
+
+ ```
+ {"type":"control_request","request_id":"req-interrupt-1","request":{"subtype":"interrupt"}}
+ ```
+
+4. 若更希望脚本化演示“打断”能力，请另建一份输入流（命名为 `request_interrupt.jsonl`，指令与上例不同）：
+
+ ```bash
+ cat <<'EOF' > docs/examples/stream-json/request_interrupt.jsonl
+ {"type":"control_request","request_id":"req-init-interrupt","request":{"subtype":"initialize","hooks":null}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请输出当前工作目录，并等待后续指令。"}]}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请列出当前目录中的所有文件。"}]}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"若无更多操作，请准备结束对话。"}]}}
+ {"type":"control_request","request_id":"req-interrupt-final","request":{"subtype":"interrupt"}}
+ EOF
+ ```
+
+ 随后结合 `timeout` 或额外的 `interrupt` 输出来模拟外部终止：
+
+ ```bash
+ timeout 10 sh -c \
+ "cat docs/examples/stream-json/request_interrupt.jsonl - | \
+ npm run qwen -- \
+ --input-format stream-json \
+ --output-format stream-json \
+ --include-partial-messages \
+ --model glm-4.6"
+ ```
+
+ 日志请看 @./logs/2.log
+ 该命令会自动发送两轮用户消息，并在最后推送 `interrupt`。当 `timeout` 到期或 CLI 处理完最后一个请求时，会立刻返回 `control_response/interrupt`，随后进程以 “OpenAI API Streaming Error: Request was aborted.” 类似日志结束——这正是预期的打断表现。
+
+> 注意：若 CLI 发出 `control_request.can_use_tool` 等事件，需要调用方实时回写 `control_response`，否则进程会等待回执。
+
+## 伪 SDK 脚本
+
+- 位置：`docs/examples/stream-json/simple_stream_json_client.py`
+- 功能：启动 CLI 子进程，自动完成 `initialize` 握手、发送用户消息，并对 `can_use_tool`、`hook_callback` 等控制请求给出示例响应。脚本会在收到 `result` 后通过 `interrupt` 结束会话。
+
+运行示例：
+
+```bash
+python docs/examples/stream-json/simple_stream_json_client.py
+```
+
+日志请看 @./logs/3.log
+
+默认脚本使用 `npm run qwen -- …` 启动 CLI，如需替换命令可设置环境变量 `QWEN_STREAM_JSON_COMMAND`，例如：
+
+```bash
+# export QWEN_STREAM_JSON_COMMAND="npm run qwen -- --input-format stream-json --output-format stream-json --include-partial-messages --model glm-4.6"
+export QWEN_STREAM_JSON_COMMAND="npm run qwen -- --input-format stream-json --output-format stream-json --include-partial-messages"
+python docs/examples/stream-json/simple_stream_json_client.py
+```
+
+脚本内部提供了 `StreamJsonClient` 类，可通过 `StreamJsonClientOptions` 自定义命令、初始化请求、用户消息、控制处理函数等，例如：
+
+```python
+import asyncio
+import sys
+
+sys.path.append("docs/examples/stream-json")
+from simple_stream_json_client import StreamJsonClient, StreamJsonClientOptions
+
+options = StreamJsonClientOptions(
+ command=["npm", "run", "qwen", "--", "--input-format", "stream-json", "--output-format", "stream-json"],
+ user_messages=[
+ {
+ "type": "user",
+ "message": {
+ "role": "user",
+ "content": [{"type": "text", "text": "举例说明 stream-json 协议用途"}],
+ },
+ }
+ ],
+ extra_handlers={
+ # 拒绝敏感工具
+ "can_use_tool": lambda client, request_id, payload: client.send_control_response(
+ request_id,
+ success=True,
+ response={"behavior": "deny", "message": "demo client blocks all tools"},
+ ),
+ },
+)
+
+client = StreamJsonClient(options)
+asyncio.run(client.run())
+```
+
+## 自动化测试
+
+新增单元测试验证了 stream-json 相关功能，可通过以下命令运行：
+
+```bash
+npx vitest run \
+ packages/cli/src/streamJson/writer.test.ts \
+ packages/cli/src/streamJson/session.test.ts \
+ packages/cli/src/nonInteractiveCli.test.ts
+```
+
+测试涵盖：
+- `system/init` 事件与会话元数据
+- 部分消息增量（`thinking_delta`、`input_json_delta` 等）
+- `result` 事件中的 `usage`、`duration_api_ms` 字段
+- `can_use_tool` 控制请求桥接逻辑
+
+通过上述步骤即可快速验证 Stream JSON 协议在 CLI 中的输出与控制通道行为。
+
+### 运行日志示例（节选）
+
+下表摘录脚本运行过程中的关键日志，并标注演示的能力：
+
+| 日志片段 | 功能说明 |
+| --- | --- |
+| `{"type":"control_response","request_id":"demo-init","success":true,...}`
`{"type":"system","subtype":"init",...}` | 脚本回写 `initialize`，CLI 输出 `system/init` 会话元数据（控制通道 + 系统事件）。 |
+| `{"type":"user","message":{"role":"user","content":"请阅读 README.md..."}}` | 客户端发送 `user` 消息，触发单轮会话。 |
+| `{"type":"stream_event","event":{"type":"message_start",...}}`
`{"type":"stream_event","event":{"type":"content_block_delta","delta":{"type":"text_delta","text":"..."}}}`
`{"type":"stream_event","event":{"type":"content_block_delta","delta":{"type":"input_json_delta",...}}}` | 增量事件补全：文本 `text_delta` 与工具输入 `input_json_delta`。 |
+| `{"type":"assistant","message":{"content":[{"type":"tool_use",...}]}}`
`{"type":"user","message":{"content":[{"type":"tool_result",...}]},...}` | CLI 发起工具调用，脚本回写 `tool_result`，展示 `can_use_tool` 桥接及工具结果回传。 |
+| 连续 `content_block_delta` 输出 README 摘要
`{"type":"assistant","message":{"content":[{"type":"text","text":"..."}]}}` | 思考/文本增量与最终完整 `assistant` 消息一致。 |
+| `{"type":"result","subtype":"session_summary","duration_api_ms":..., ...}` | `result` 事件包含 `duration_api_ms`、`num_turns` 等统计字段。 |
+| `{"type":"control_response","request_id":"demo-interrupt","success":true,...}` | 脚本发送 `interrupt` 收尾，CLI 返回成功响应。 |
+
+## 手工验证指南
+
+如下命令便于人工对照本次实现的关键能力是否落实：
+
+1. **初始化与增量事件**（验证 `system/init`、`stream_event` 生命周期对齐 Claude 协议）
+ ```bash
+ npm run qwen -- \
+ --input-format stream-json \
+ --output-format stream-json \
+ --include-partial-messages \
+ --model glm-4.6 \
+ < docs/examples/stream-json/request.jsonl
+ ```
+ 期望输出：初始化时包含完整 `system/init` 字段；助手回复过程中出现 `message_start`、`content_block_start/delta/stop` 及 `message_stop`。
+
+2. **实时控制通道**（验证 `can_use_tool`、`hook_callback` 等高级子类型）
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ # 依次输入：
+ {"type":"control_request","request_id":"req-init","request":{"subtype":"initialize"}}
+ {"type":"user","message":{"role":"user","content":[{"type":"text","text":"请执行 ls"}]}}
+ ```
+ 期望输出：CLI 对初始化请求返回 `control_response.success`，在触发工具调用时向上游发送 `control_request.can_use_tool`，同时可看到钩子回执产生的 `system hook_callback` 消息。
+
+3. **MCP 消息桥接**（验证 `mcp_message` 透传）
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ {"type":"control_request","request_id":"req-mcp","request":{"subtype":"mcp_message","server_name":"default","message":{"jsonrpc":"2.0","id":"1","method":"tools/list"}}}
+ ```
+ 期望输出：`control_response.success` 中的 `mcp_response.result.tools` 列出已注册的 MCP 工具。若未配置 MCP，可用于验证错误回执 `control_response.error` 的结构化字段。
+
+4. **工具结果回链**（验证 `user` 信封携带 `tool_result` 与 `parent_tool_use_id`）
+ ```bash
+ npm run qwen -- --input-format stream-json --output-format stream-json --model glm-4.6
+ {"type":"user","message":{"content":[{"type":"tool_result","tool_use_id":"demo-tool","content":[{"type":"text","text":"手动工具结果"}]}]},"parent_tool_use_id":"demo-tool"}
+ ```
+ 期望输出：CLI 会在后续调用 `runNonInteractive` 时读取该 `tool_result`，并在需要时继续衍生对话，不再记录用户回响。
+
+上述手工步骤覆盖了 OpenSpec 剩余任务中新增的高级控制请求、系统初始化字段、增量事件补全、用户信封扩展与错误语义规范化等核心能力。
+
+## 自动化验证脚本
+
+若需一次性跑通上述控制通道场景，可执行：
+
+```bash
+python docs/examples/stream-json/validate_stream_json_cli.py
+```
+
+脚本将自动启动 `qwen code`，依次触发 `initialize`/`hook_callback`/`can_use_tool`/`mcp_message` 等事件，并把所有请求/响应 JSON 行实时打印出来，最终以表格形式汇总每个断言的通过状态。可通过以下环境变量调整行为：
+
+- `QWEN_STREAM_JSON_COMMAND`：自定义 CLI 启动命令。
+- `STREAM_JSON_VALIDATE_VERBOSE=0`：如需关闭逐行日志，可将该变量设为 `0`。
+- `STREAM_JSON_VALIDATE_PROMPT=1`：启用“用户 prompt 触发工具调用”的附加场景（需要可用模型或代理凭据）。
+- `STREAM_JSON_VALIDATE_TOOL_RESULT=1`：启用“tool_result + parent_tool_use_id 链路”的附加场景。

+
+## Agent 会话循环能力
+
+- **结论**：需补充状态化的 `QwenAgentClient` 设计，支持流式连接、Hook 注入与 SDK MCP 注册，让 IDE / 应用能够在同一会话内执行多轮对话、动态插入消息并与控制协议交互。（参考 `third-party/anthropics/claude-agent-sdk-python/src/claude_agent_sdk/client.py`）

+
+- Agent SDK 与 CLI 共享 STDIN/STDOUT 双向 JSONL 通道，统一传输 `chat.completion*`、`result/*`、`control_request` 等事件。
+- 双向通信链路：CLI 逐行输出 `chat.completion`/`result/*`/`control_request` 至 stdout，SDK 解析后按需通过 stdin 回写 `request`/`control_response`，当出现 `control_request{subtype:"mcp_message"}` 时，ControlPlane 会将 JSON-RPC 转发至本地 MCP Server 并回传 `mcp_response`。
+- qwen-code CLI 已接入 OpenTelemetry，上报模型调用、工具执行、CLI 内部事件；Agent SDK 需独立接入，并通过 Trace/Span ID 串联端到端链路，构建统一排障视角。
+- 控制协议的事件语义与 CLI 输出格式规范保持一致，详见配套的 `stream-json` RFC。
+- 事件分类提示：关于 `result/*`、`request`、`control_request` 等事件的详细语义，请参阅《qwen-code-cli-output-format-stream-json-rfc_cn.md》的“事件机制分类”章节。
+
+## 核心能力映射
+
+| 能力域 | 关键内容 | 当前能力 | 后续演进 |
+| --- | --- | --- | --- |
+| 会话调度 | 会话路由、Worker 绑定、复用策略 | SDK 侧提供 Router、Worker 池调度 | 增强会话分支/子 Agent 调度 |
+| 进程治理 | 子进程启动、监控、重启 | ProcessMgr 负责生命周期与资源限制 | 引入资源配额、故障自动隔离 |
+| 控制协议 | 权限回调、Hook、MCP | ControlPlane 统一处理 `control_request` | 扩展更多 Hook 点与审批策略 |
+| IPC 协议 | JSON Lines、输入输出格式 | IPC 层实现 `stream-json`/`stream-chunk-json` | 丰富事件类型、协议版本协商 |
+| 可观测性 | 日志、指标、Trace | SDK 与 CLI 各自接入 OTel，并输出结构化日志 | 统一指标命名与跨组件追踪分析 |
+
+- 会话调度与控制层需要保证 Worker 独占机制、会话隔离与资源回收。
+- 控制协议以 request/response 模型运行，SDK 必须在超时前回写 `control_response`，确保 CLI 不被阻塞。
+
+## Agentic 会话能力
+
+| 能力块 | 设计重点 | 接口/结构 |
+| --- | --- | --- |
+| 会话循环 | 状态化 `QwenAgentClient`，区分连接与消息流阶段 | `connect()`、`disconnect()`、`Query.initialize()` |
+| 会话上下文 | 支持异步上下文管理与资源释放 | `__aenter__` / `__aexit__`、`async with QwenAgentClient` |
+| 消息流处理 | 同一会话内追加输入并消费流式输出 | `query()`、`stream_input()`、`receive_messages()`、`receive_response()` |
+| 动态控制 | 运行时切换模型/权限、触发中断并回读初始化能力 | `interrupt()`、`set_permission_mode()`、`set_model()`、`get_server_info()` |
+| 传输抽象 | 可插拔 Transport 支持本地/远程 CLI 与缓冲守护 | `Transport`、`SubprocessCLITransport`、`max_buffer_size` 校验 |
+
+### 会话循环与上下文
+
+- `QwenAgentClient.connect()` 支持字符串与异步流模式，可在首次 `initialize` 时注入 Hook 与 SDK MCP Server，保障 IDE/服务多轮会话。
+- `disconnect()` 清理 `_query` 及 Transport，结合 `async with` 自动化连接/释放流程，避免遗留子进程。
+- 参数校验需提前阻止互斥选项（如 `can_use_tool` 与 `permission_prompt_tool_name` 同时启用），提升配置体验。
+
+### 消息流处理
+
+- `query()` 自动补全 `session_id` 并写入 JSONL，支持脚本/界面按需追加消息。
+- `stream_input()` 负责增量写入并在异常时清空缓冲、记录调试日志，维持长流程稳定性。
+- `receive_messages()` 遍历所有事件，`receive_response()` 检测到 `ResultMessage` 后提前收束，方便界面感知一次回答完成。
+- `include_partial_messages` 选项允许透传增量 chunk，配合 `stderr`/`debug_stderr` 捕获底层诊断输出，便于复杂界面实时渲染。
+
+### 动态控制接口
+
+- `_send_control_request` 支持 `interrupt`、`set_permission_mode`、`set_model` 等子类型，实现手动打断、权限模式切换与热切模型。
+- `get_server_info()` 回读 CLI 初始化能力（协议版本、指令集等），用于动态配置前端或策略。
+- `async query(...)->AsyncIterator` 暴露在脚本化场景，实现一次性消费完整响应，同时保留自定义 Transport 的可能。
+
+### 单次查询与多 Agent 编排
+
+- `query()` 快速入口封装了会话生命周期，适合集成脚本或批量任务；当传入自定义 `Transport` 时可复用远程 CLI 或 Agent 服务。
+- `agents` 配置将多 Agent 拓扑映射到 CLI `--agents` 参数，结合 `fork_session` 支持会话分叉与子 Agent 路由。
+- CLI 命令生成时需根据 `setting_sources`、`allowed_tools`、`mcp_servers` 等选项拼装 JSON，保证 SDK 与 CLI 能力一致。
+
+### Hook 与 MCP 桥接
+
+- Hook 初始化阶段将 `HookMatcher` 列表转换为 `hookCallbackIds`，`hook_callback` 事件据此回调宿主逻辑，支持 `PreToolUse`、`PostToolUse`、`UserPromptSubmit` 等关键节点。
+- SDK 侧 `create_sdk_mcp_server`/`defineTools` 在宿主进程构建 MCP Server，`mcp_message` 请求触发 `tools/list`、`tools/call`、`initialize` 等 JSON-RPC，避免额外子进程。
+- 权限审批通过 `PermissionResultAllow`/`PermissionResultDeny` 及 `PermissionUpdate` 结构返回细粒度策略，可在 Hook 或工具回调中按需调整。
+- **示例：PreToolUse 与 UserPromptSubmit 组合**（参考 `third-party/anthropics/claude-agent-sdk-python/examples/hooks.py`）：
+ ```python
+ import asyncio
+ from qwen_agent_sdk import HookContext, HookMatcher, QwenAgentOptions, QwenSDKClient
+
+
+ async def block_risky_bash(
+ input_data: dict[str, object],
+ tool_use_id: str | None,
+ context: HookContext,
+ ) -> dict[str, object]:
+ command = input_data.get("command", "") if isinstance(input_data, dict) else ""
+ if isinstance(command, str) and "rm -rf" in command:
+ return {
+ "hookSpecificOutput": {
+ "hookEventName": "PreToolUse",
+ "permissionDecision": "deny",
+ "permissionDecisionReason": "阻止危险删除命令",
+ }
+ }
+ return {}
+
+
+ async def inject_user_memory(
+ input_data: dict[str, object],
+ tool_use_id: str | None,
+ context: HookContext,
+ ) -> dict[str, object]:
+ return {
+ "hookSpecificOutput": {
+ "hookEventName": "UserPromptSubmit",
+ "additionalContext": "请牢记用户最喜欢的颜色是蓝色。",
+ }
+ }
+
+
+ options = QwenAgentOptions(
+ allowed_tools=["Bash"],
+ hooks={
+ "PreToolUse": [HookMatcher(matcher="Bash", hooks=[block_risky_bash])],
+ "UserPromptSubmit": [HookMatcher(matcher=None, hooks=[inject_user_memory])],
+ },
+ )
+
+
+ async def main() -> None:
+ async with QwenSDKClient(options=options) as client:
+ await client.query("尝试运行命令: rm -rf /tmp")
+ async for message in client.receive_response():
+ ...
+
+
+ asyncio.run(main())
+ ```
+
+### 传输层扩展
+
+- `Transport` 抽象允许替换默认的 `SubprocessCLITransport`，以适配远程 CLI、Agent 服务或容器托管场景。
+- 传输层在握手前执行版本检测与 `max_buffer_size` 限制，输出超限时抛出结构化错误并清理缓冲，防止内存膨胀。
+- 可通过选项控制工作目录、环境变量及 stderr 捕获，为 IDE 与服务端部署提供灵活拓扑。
+- `SubprocessCLITransport` 构建 CLI 命令时需注入 `--mcp-config`、`--agents`、`--setting-sources` 等参数，并在环境变量中写入 `CLAUDE_CODE_ENTRYPOINT`、自定义 `env`、`user` 配置以确保子进程能力对齐。
+- **示例：自定义远程 Transport**（参考 `third-party/anthropics/claude-agent-sdk-python/src/claude_agent_sdk/_internal/transport/__init__.py`）：
+ ```python
+ import json
+ from collections.abc import AsyncIterator
+ import httpx
+ from qwen_agent_sdk import QwenAgentOptions, QwenSDKClient
+ from qwen_agent_sdk.transport import Transport
+
+
+ class RemoteHTTPTransport(Transport):
+ def __init__(self, endpoint: str) -> None:
+ self._client = httpx.AsyncClient(base_url=endpoint, timeout=30.0)
+ self._ready = False
+
+ async def connect(self) -> None:
+ self._ready = True
+
+ async def write(self, data: str) -> None:
+ await self._client.post("/ingress", content=data.encode("utf-8"))
+
+ def read_messages(self) -> AsyncIterator[dict[str, object]]:
+ async def iterator() -> AsyncIterator[dict[str, object]]:
+ async with self._client.stream("GET", "/egress") as response:
+ async for line in response.aiter_lines():
+ if line:
+ yield json.loads(line)
+ return iterator()
+
+ async def close(self) -> None:
+ await self._client.aclose()
+ self._ready = False
+
+ def is_ready(self) -> bool:
+ return self._ready
+
+ async def end_input(self) -> None:
+ await self._client.post("/ingress/close")
+
+
+ transport = RemoteHTTPTransport("https://cli-gateway.internal")
+ options = QwenAgentOptions(system_prompt="所有命令都通过远程 CLI 网关执行。")
+
+
+ async with QwenSDKClient(options=options, transport=transport) as client:
+ await client.query("读取 README.md 并总结三条要点。")
+ async for message in client.receive_response():
+ ...
+ ```
+
+### 调试与环境注入
+
+- CLI 编排需根据 `QwenAgentOptions` 生成完整命令列，区分流式与一次性执行（`--input-format stream-json` 与 `--print`）。
+- `options.stderr` 与 `debug_stderr` 支持在 SDK 侧接管 CLI 调试输出，结合 anyio TaskGroup 实时读取 stderr 流。
+- `cwd`、`env`、`user` 等参数决定子进程工作目录与权限边界，SDK 应在启动时显式传入并在断连时回收资源。
+- **示例：错误回调与重试**（参考 `third-party/claude-agent-sdk-python-demo/add_my_permission.py`）：
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ PermissionDecision,
+ PermissionRequest,
+ PermissionUpdate,
+ QwenAgentOptions,
+ QwenSDKClient,
+ )
+
+
+ async def decide_permission(request: PermissionRequest) -> PermissionDecision:
+ if request.tool_name == "Write" and request.input and "rm -rf" in str(request.input):
+ return PermissionDecision(allow=False, reason="拒绝可能破坏工作的命令")
+ return PermissionDecision(allow=True, updates=[PermissionUpdate(mode="allow")])
+
+
+ async def main() -> None:
+ options = QwenAgentOptions(
+ allowed_tools=["Read", "Write"],
+ permission_callback=decide_permission,
+ permission_mode="ask",
+ )
+
+ async with QwenSDKClient(options=options) as client:
+ try:
+ await client.query("删除所有临时文件并写入新的日志")
+ async for message in client.receive_response():
+ ...
+ except Exception:
+ await client.query("改为仅清理 ./tmp 目录")
+ async for message in client.receive_response():
+ ...
+
+
+ anyio.run(main)
+ ```

+| Go | 待定 | 待定 | 待定 | 复用控制协议，暴露通用 API | TODO |
+| Java | 待定 | 待定 | 待定 | 面向企业场景的 SDK | TODO |
+
+### Python SDK 细节
+
+- **运行时与分发**: 需 Python 3.10+；采用 `pyproject.toml + hatchling` 发布；提供 `qwen_agent_sdk` 命名空间与 `py.typed`。
+- **环境依赖**: 需预装 Node.js 及 `qwen-code` CLI，SDK 启动前通过 `which qwen` 或 `QWEN_BIN` 环境变量定位二进制。
+- **核心依赖**: `anyio>=4`、`typing_extensions`、`mcp>=0.1`、`pydantic>=2`。
+- **适用场景**：第三方后端服务、希望自定义交互体验或进行服务端调用的场景。
+- **API 设计**：
+ - `async def query(...) -> AsyncIterator[Message]`：对齐 Anthropic `query()` 的流式接口。
+ - `class QwenSDKClient`：支持 `async with`、会话续写与中断管理。
+ - `QwenAgentOptions`：包含 `system_prompt`、`setting_sources`、`permission_mode`、`cwd`、`fork_session` 等参数。
+ - `@tool` 装饰器 + `create_sdk_mcp_server`：将 Python 函数注册为 MCP 工具。
+- **实现要点**：
+ - `StdIOSubprocessTransport` 启动 `qwen` CLI，写入 JSONL，读取流式 chunk。
+ - `_handle_control_request()` 对 `can_use_tool`、`hook_callback`、`mcp_message` 等 `subtype` 执行回调，并写入 `control_response`。
+ - **Hook 体系**：支持 `PreToolUse`、`PostToolUse`、`UserPromptSubmit` 等事件，可返回 JSON 指令以调整会话流程，与 Anthropic Hook JSON 保持一致。
+ - `Query.initialize()` 首次发送 `control_request{subtype:"initialize"}`，同步 Hook 配置与能力声明。
+ - 支持 `PermissionResult`、Hook JSON 与 MCP JSON-RPC 的统一封装。
+- **日志与可观测**：
+ - 默认输出结构化 JSON 日志，支持 `structlog` 注入。
+ - **轻量日志约定**：遵循 `logging` 风格输出结构化 JSON，可通过 `options.stderr`/`debug_stderr` 捕获 CLI 原始错误流，加速排障。
+ - 规划内置 OpenTelemetry Tracer/Meter，记录会话耗时、传输错误、Worker 利用率。
+- **健壮性**：
+ - CLI 崩溃时自动重试与会话 fork，保存最近成功结果实现断点续传。
+ - 回调异常时返回 `control_response{subtype:"error"}`，触发 CLI 安全回退。
+- **测试体系**：
+ - `pytest + pytest-asyncio` 覆盖核心流程。
+ - `ruff + mypy` 保证代码质量。
+- **示例：快速流式对话**（参考 `third-party/anthropics/claude-agent-sdk-python/examples/quick_start.py`）：
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ ResultMessage,
+ TextBlock,
+ query,
+ )
+
+
+ async def main() -> None:
+ options = QwenAgentOptions(
+ system_prompt="你是一名示例助手，回答保持简洁。",
+ allowed_tools=["Read"],
+ max_turns=1,
+ )
+
+ async for message in query(prompt="2 + 2 等于多少？", options=options):
+ if isinstance(message, AssistantMessage):
+ for block in message.content:
+ if isinstance(block, TextBlock):
+ print(block.text)
+ elif isinstance(message, ResultMessage) and message.total_cost_usd:
+ print(f"本轮花费: ${message.total_cost_usd:.4f}")
+
+
+ anyio.run(main)
+ ```
+- **示例：多 Agent 与设置源**（参考 `third-party/anthropics/claude-agent-sdk-python/examples/agents.py`、`third-party/anthropics/claude-agent-sdk-python/examples/setting_sources.py`）：
+ ```python
+ from qwen_agent_sdk import AgentDefinition, QwenAgentOptions, query
+
+
+ options = QwenAgentOptions(
+ agents={
+ "doc-writer": AgentDefinition(
+ description="输出结构化说明",
+ prompt="你是资深文档工程师，请附带步骤解释。",
+ tools=["Read", "Write"],
+ ),
+ "tester": AgentDefinition(
+ description="生成并运行测试",
+ prompt="你负责编写测试并验证结果。",
+ tools=["Read", "Write", "Bash"],
+ ),
+ },
+ setting_sources=["user", "project"],
+ )
+
+
+ async for message in query(
+ prompt="请调用 doc-writer 说明 AgentDefinition 的用途。",
+ options=options,
+ ):
+ ...
+ ```
+- **示例：内嵌 MCP 工具**（参考 `third-party/anthropics/claude-agent-sdk-python/examples/mcp_calculator.py`）：
+ ```python
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ QwenSDKClient,
+ TextBlock,
+ create_sdk_mcp_server,
+ tool,
+ )
+
+
+ @tool("add", "计算两个数之和", {"a": float, "b": float})
+ async def add_numbers(args: dict[str, float]) -> dict[str, object]:
+ total = args["a"] + args["b"]
+ return {"content": [{"type": "text", "text": f"{args['a']} + {args['b']} = {total}"}]}
+
+
+ calculator = create_sdk_mcp_server(
+ name="calculator",
+ version="1.0.0",
+ tools=[add_numbers],
+ )
+
+
+ options = QwenAgentOptions(
+ mcp_servers={"calc": calculator},
+ allowed_tools=["mcp__calc__add"],
+ )
+
+
+ async with QwenSDKClient(options=options) as client:
+ await client.query("请调用 mcp__calc__add 计算 6 + 7。")
+ async for message in client.receive_response():
+ if isinstance(message, AssistantMessage):
+ for block in message.content:
+ if isinstance(block, TextBlock):
+ print(block.text)
+ else:
+ ...
+ ```
+
+### TypeScript SDK 细节
+
+- **运行时与分发**: 需 Node.js 18+；包名 `@qwen-agent/sdk`，默认 ESM 导出并通过 `exports` 暴露 CJS；使用 `tsup` 生成 `dist/esm`、`dist/cjs`、`dist/types`。
+- **核心依赖**: `@qwen-code/cli`（peerDependency）、`zx/execa`、`eventemitter3`。
+- **API 能力**：
+ - `createAgentManager(options)`：提供 `createSession`、`run`、`forkSession`。
+ - `session.stream(task)`：返回 `AsyncIterable`，可 `for await` 消费。
+ - `onPermissionRequest`：以 `allow/deny/ask` + 规则返回权限决策。
+ - `settingSources`：默认关闭，需要显式声明 `["user","project","local"]` 等条目才会加载对应设置文件。
+ - `defineTools`：注册 MCP 工具，与 CLI 会话共享上下文。
+ - `agents` 选项：支持内联多 Agent 拓扑，结合 `forkSession` 构建子 Agent。
+- **实现要点**：
+ - 使用 `execa` 启动 CLI，统一解析 stdout 为 `AgentStreamChunk`。
+ - `ProcessTransport` 逐行解码 stdout (`JSON.parse`)，通过 `EventEmitter` 推送 `control_request`、`result/*`、`chat.completion*` 事件，所有反向 `control_response` 共用子进程 stdin。
+ - 维持 `result/heartbeat` 定时器，超时自动重启 Worker。
+ - `pendingControl` 映射配合 `request_id` 路由 `control_request`。
+ - 回调 Promise 生成标准化 `control_response` payload；未注册时走默认策略。
+ - `onPermissionRequest`、`onHookEvent` 等回调 Promise 化处理，统一生成 `control_response`，未注册时沿用默认策略避免 CLI 阻塞。
+ - `defineTools()` 将 TS 函数组装为 in-process MCP server，透传 JSON-RPC。
+ - 初始化阶段等待 CLI 首条 `chat.completion` 握手信息，并通过 `control_request{subtype:"initialize"}` 发送 Hook/工具能力。
+ - 异常场景记录 verbose 日志并返回 `control_response{subtype:"error"}`。
+- **工程体系**：
+ - `tsup` 产出 `dist/esm`、`dist/cjs` 与 `dist/types`。
+ - 测试矩阵使用 `vitest` + `tsx`，结合 CLI mock 校验流式输出、权限回调。
+ - 提供 `enableVerboseLogging()` 开关、`logger`/`stderr` 回调以及 OpenTelemetry Trace 规划。
+
+### 其它语言路线（TODO）
+
+- **Go/Java**：计划复用统一控制协议与 Worker 调度策略，面向企业场景与后端服务。
+- 将在 Python/TypeScript 稳定后补充 SDK 设计与实现细节。
+
+## 控制协议与 MCP 集成
+
+| 通道 | 发起方 | 典型事件 | 回执要求 | 目的 |
+| --- | --- | --- | --- | --- |
+| `chat.completion*` | CLI → SDK | 模型回复、工具调用、收尾摘要 | 无需回执 | 承载主流程消息 |
+| `result/*` | CLI → SDK | `result/command`、`result/heartbeat`、`result/cancel`、`x-qwen-session-event` | 无需回执 | 发布状态与辅助信息 |
+| `*request` | SDK → CLI | `command_hint_request`、`heartbeat_request`、`control/cancel` | CLI 以 `result/*` 响应 | 触发即时操作 |
+| `control_request` | CLI → SDK | `can_use_tool`、`hook_callback`、`mcp_message` | 需回写 `control_response` | 执行权限判定、Hook、MCP 调用 |
+
+- 所有控制事件通过统一 STDIN/STDOUT 管道传输，SDK 必须确保在约定超时内响应。
+- MCP 集成在 SDK 进程内创建 server，无需额外子进程或网络服务。
+- 授权回调与 MCP 调用解耦：CLI 仍负责触发 `can_use_tool`，SDK 收到后执行权限逻辑，随后才能处理 `mcp_message`。

+ MCP->>Tool: 调用异步处理函数
+ Tool-->>MCP: 处理结果
+ MCP-->>Control: jsonrpc result (mcp_response)
+ Control-->>CLI: control_response (stdin)
+```
+
+- 初始化阶段通过 `control_request{subtype:"initialize"}` 同步 Hook 配置与能力声明。
+- 回调异常时，SDK 需记录日志并返回 `control_response{subtype:"error"}`，CLI 遵循安全回退策略。
+
+| `control_request.subtype` | 输入要点 | SDK 响应约束 | 说明 |
+| --- | --- | --- | --- |
+| `initialize` | 携带 `hooks` 配置、可选 MCP 能力声明 | 返回 `control_response` 确认或报错；存档 `_initialization_result` | 需将 `HookMatcher` 中的回调映射为 `hookCallbackIds`，便于后续触发 |
+| `can_use_tool` | 提供 `tool_name`、`input`、`permission_suggestions` | 返回 `behavior=allow/deny`，可附带 `updatedInput`、`updatedPermissions` | `updatedPermissions` 由 `PermissionUpdate` 数组组成，支持规则/目录/模式调整 |
+| `hook_callback` | 提供 `callback_id`、Hook 输入上下文 | 查找对应回调并返回 JSON 结果 | 需在连接阶段缓存回调映射，未命中应返回结构化错误 |
+| `mcp_message` | 提供 `server_name`、`message` JSON-RPC | 调用 SDK 内置 MCP server，封装 `mcp_response` | 支持 `initialize`、`tools/list`、`tools/call` 等标准方法，出错时返回 JSON-RPC 错误对象 |
+
+- `PermissionUpdate` 结构支持 `addRules`、`replaceRules`、`removeRules`、`setMode`、`addDirectories`、`removeDirectories` 等类型，需精确传递规则内容与目录集合以满足企业级权限治理。
+- Hook 配置允许多事件、多匹配器组合：`HookMatcher.matcher` 指定匹配条件，`hooks` 填写回调函数列表，SDK 在初始化时生成回调 ID，并在 `hook_callback` 阶段路由执行。
+
+## 通信模式与 MCP 能力
+
+| 模块 | 形态 | 关键说明 |
+| --- | --- | --- |
+| IPC 模式 | STDIN/STDOUT JSON Lines | SDK 启动本地 `qwen` 子进程，以 JSON Lines 进行通信；协议细节对齐《qwen-code-cli-output-format-stream-json-rfc_cn.md》，保持 `/`、`@`、`?` 指令的即时回执。 |
+| In-Process MCP Server | SDK 内嵌 MCP Server | 依赖 `mcp>=0.1` 在宿主进程创建 MCP Server，透传 `@tool`/`defineTools` 定义的函数，无需额外子进程或网络服务。 |
+
+- **IPC 实现要点**：
+ - `SubprocessCLITransport`（或等价实现）通过同一 STDIN/STDOUT 管道处理正向/反向消息，无需额外套接字。
+ - CLI 输出 `chat.completion`/`chat.completion.chunk` 时需在首条消息的 `metadata` 携带 `protocol_version`、`input_format`、`output_format`、`capabilities`。
+ - 事件语义覆盖 `result/heartbeat`、`result/cancel`、`x-qwen-session-event`、`control_request/control_response`，并提供 OpenAI 风格错误对象。
+- **MCP 事件链路**：
+ - CLI 通过 `control_request{subtype:"mcp_message"}` 将 JSON-RPC 请求写入 stdout，SDK 转发给本地 MCP Server 执行 `tools/list`、`tools/call`。
+ - 执行结果封装为 `control_response` 写回 stdin，形成闭环。
+- **授权分工与优势**：
+ - CLI 触发 `control_request{subtype:"can_use_tool"}` 由 SDK 决策授权，MCP 调用链路与权限判定解耦。
+ - 工具执行下沉到 SDK 进程内，降低延迟；Hook 能力可沿同一通路后续接入，与 Claude Agent SDK 实践保持一致。
+
+## Worker 池与复用
+
+| 维度 | 设计要点 | 实施状态 |
+| --- | --- | --- |
+| 状态机 | 空闲 → 占用 → 空闲，单 Worker 独占会话 | 已设计 |
+| 复用策略 | 会话结束不销毁进程，清理上下文后复用 | 规划落地 |
+| 安全保障 | 会话隔离、资源清理、健康检查 | 随 Worker 池实现同步 |
+| 配置项 | `min_workers`、`max_workers`、`idle_timeout`、`max_sessions_per_worker`、`health_check_interval` | 需在 SDK/CLI 配置中暴露 |
+| 可观测 | 结构化日志、指标导出、Trace 链接 | SDK/CLI 各自接入 |
+
+- **环境说明**: Worker 本质是 qwen-code CLI 子进程，其容器/沙箱与工具桥接由 CLI 管理，SDK 仅通过 STDIN/STDOUT 进行调度与控制。
+- Worker 仅在单会话期间占用，保证隔离；会话结束后回到空闲池。
+- 复用依赖清理会话变量、关闭文件句柄、重置环境变量。
+- 健康检查覆盖内存泄漏、僵尸进程、卡死检测，异常时自动重启。
+- 典型配置示例：
+
+```yaml
+worker_pool:
+ min_workers: 5
+ max_workers: 50
+ idle_timeout: 1800 # 30 分钟
+ max_sessions_per_worker: 100
+ health_check_interval: 60
+```
+
+- 会话日志需记录 `session_id`、`prompt_id`、耗时、命令摘要，支持回传至集中式日志系统。
+- 指标采集聚焦活跃/空闲数量、排队时长、重启次数、失败率等，Trace 在 SDK → CLI → 工具调用间传播。
+
+## 配置注入与设置管理
+
+| 项目 | 能力描述 | 说明 |
+| --- | --- | --- |
+| `settings_profile` | 为单个 `QwenClient` 指定独立配置 | 影响该客户端维护的 Worker 池及子进程 |
+| `system/system_defaults` | 传入绝对路径或 JSON overrides | 映射到 CLI `QWEN_CODE_SYSTEM_SETTINGS_PATH` 等环境变量 |
+| `user/workspace` | JSON 对象或文件/目录路径 | SDK 在临时目录生成 `settings.json` 并挂载至 CLI |
+| `overrides` | 键值覆盖，如 `model.name`、`tools.allowed` | 直接写入临时配置文件 |
+
+- **生态复用**：沿用 CLI 多层设置体系 (`SettingScope.System/SystemDefaults/User/Workspace`)，不同 `QwenClient` 相互隔离，未提供 profile 时走 CLI 默认加载顺序。
+- **实现步骤**：
+ 1. 在 `QwenClientOptions`/`QwenAgentOptions` 新增 `settings_profile` 字段，Python/TypeScript SDK 均需支持。
+ 2. Worker 池启动 CLI 前，将 profile 写入隔离目录，并设置 `--setting-sources`/`--settings` 或相关参数。
+ 3. 写入 `QWEN_CODE_USER_SETTINGS_PATH`、`QWEN_CODE_WORKSPACE_SETTINGS_PATH` 等环境变量，以指向生成的临时配置文件。
+ 4. Worker 池销毁时清理临时目录，避免配置泄漏。
+- **日志与排障**：日志中打印 profile 摘要（脱敏），便于排查配置错配。
+- **安全考量**：配置仅由宿主应用注入，不做共享路径回退，防止跨租户污染，需提醒妥善管理敏感 Token/路径。
+- **兼容性**：CLI 需补齐对新环境变量的解析，未识别的变量应回退默认行为（忽略）。
+- **现状提醒**：当前 CLI 尚未支持单子进程独立配置，需要后续 RFC/PR 推进 `--settings-profile` 及相关环境变量能力。
+
+## Agent SDK 调度层能力
+
+| 模块 | 核心职责 | 现状 | 后续工作 |
+| --- | --- | --- | --- |
+| IPC 封装 | JSON Lines 解析与写入，事件路由 | CLI 仍为文本 STDIN，需扩展 | 引入 `StdinReaderService`、`StdoutWriterService`、增强 `main()` |
+| 进程管理 | 启动、监控、资源限制、日志 | 初步设计 | 建立资源配额与异常重启策略 |
+| 控制协议 | 权限回调、Hook 注入 | CLI 仅有 ApprovalMode | 新增权限接口、Hook 体系与插桩 |
+| 输入输出格式 | `--input-format/--output-format` | 需 CLI 支持 `stream-json` | 完成参数解析与 TUI 自动禁用 |
+| 事件语义 | `result/heartbeat`、`control_request` 等 | 定义中 | 与 CLI 输出格式 RFC 对齐实现 |
+
+- `docs/ipc/qwen-chat-request-schema.json` 扩展自 OpenAI `/chat/completions`，增加 `session_id`、`prompt_id`、`origin`、`tool_call_id` 字段。
+- 错误语义需要对齐 CLI 输出格式：致命错误输出 OpenAI 风格错误对象；可恢复错误通过 `chat.completion` 表示。
+- 需要确保 `/`、`@`、`?` 指令请求的即时响应与事件派发。
+
+## 可观测性与调试
+
+| 领域 | 要点 |
+| --- | --- |
+| 日志 | SDK 默认结构化 JSON，CLI 可透传 stderr，支持 `logger` 注入 |
+| 指标 | SDK/CLI 各自导出活跃 Worker、排队时长、错误数等，规划统一指标命名 |
+| Trace | 生成会话级 Span，传播至 CLI 与工具调用链路，实现端到端排障 |
+| 调试工具 | TypeScript 提供 `enableVerboseLogging()`，Python 支持捕获 `debug_stderr`，两侧均计划引入 OTel |
+
+- 第三方服务需记录消息序列，支持审计与问题重放。
+- CLI 命令示例可用于本地调试（详见输出格式 RFC）。
+
+## 集成模式
+
+| 模式 | 适用场景 | 关键特性 |
+| --- | --- | --- |
+| 宿主进程引入 SDK | IDE 插件、企业内部工具、CLI 扩展 | 直接在宿主进程启动 Worker 池，通过 IPC JSONL 与 CLI 通信，支持同步与流式输出 |
+
+**快速上手示例**：
+
+```python
+from qwen_agent_sdk import QwenClient
+
+with QwenClient(binary_path="qwen", model="qwen3-coder-plus") as client:
+ result = client.chat(
+ task="扫描并修复 main.py 中的潜在 bug",
+ workspace="/repos/demo"
+ )
+ print(result.summary)
+```
+
+- 第三方程序可依赖 `qwen-agent-sdk` 统一管理会话、工具与权限策略。
+- SDK 需支持会话重放与取消、心跳维持与超时控制。
+- **示例：一体化会话脚手架**（参考 `third-party/claude-agent-sdk-python-demo/quick_start_example.py`）：
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ QwenSDKClient,
+ TextBlock,
+ create_sdk_mcp_server,
+ query,
+ tool,
+ )
+
+
+ @tool("get_system_info", "获取系统信息", {})
+ async def get_system_info(_: dict[str, object]) -> dict[str, object]:
+ import os
+ import platform
+
+ summary = "\n".join(
+ [
+ f"- 操作系统: {platform.system()} {platform.release()}",
+ f"- Python 版本: {platform.python_version()}",
+ f"- 当前目录: {os.getcwd()}",
+ ]
+ )
+ return {"content": [{"type": "text", "text": summary}]}
+
+
+ async def run_all_examples() -> None:
+ # 1) 基础问答
+ async for msg in query(prompt="你好，做个自我介绍。"):
+ if isinstance(msg, AssistantMessage):
+ for block in msg.content:
+ if isinstance(block, TextBlock):
+ print(block.text)
+
+ # 2) 定制参数 + 流式消费
+ options = QwenAgentOptions(system_prompt="你是一名资深助手，善于步骤化回答。")
+ async for msg in query("解释一下多进程和多线程的差异", options=options):
+ ...
+
+ # 3) 注册自定义工具
+ server = create_sdk_mcp_server(name="my-tools", version="1.0.0", tools=[get_system_info])
+ async with QwenSDKClient(
+ options=QwenAgentOptions(
+ mcp_servers={"tools": server},
+ allowed_tools=["mcp__tools__get_system_info"],
+ )
+ ) as client:
+ await client.query("请获取当前运行环境")
+ async for msg in client.receive_response():
+ ...
+
+
+ anyio.run(run_all_examples)
+ ```
+
+## 开放事项与后续计划
+
+| 方向 | 待完成事项 |
+| --- | --- |
+| CLI 协议支持 | 补齐 `stream-json` 输入输出、事件语义与握手元数据 |
+| 控制协议 | 实现权限回调 API、Hook 插桩、MCP `mcp_message` 通路 |

+# Qwen-Code Agent Framework Architecture Design (Clean Version)
+
+## Overview
+
+| Field | Details |
+| --- | --- |
+| Design Version | v1.1 |
+| Last Updated | 2025-10-10 |
+| Architecture Scope | Qwen-Code Agent SDK and qwen-code CLI subprocess orchestration, control protocol, observability, and configuration system |
+| Key Objectives | Provide third-party applications with unified IPC communication, worker pool governance, permission control, and tool bridging capabilities |
+
+- **Core Component**: This document focuses on the Qwen-Code Agent SDK, which encapsulates session routing, control protocol handling, and worker pool governance inside the host process to deliver unified access for multi-language scenarios.
+- **Core Responsibilities**: Session scheduling and routing; CLI subprocess lifecycle and resource governance; control protocol hooks and permission adjudication; lightweight logging and observability integration; telemetry collection (logs, metrics, traces).
+- **Core Functions**: Supports synchronous/asynchronous task execution, streaming output, session management, error handling and retries, in-process MCP tool bridging, and isolated configuration injection.
+- Wraps the CLI subprocess lifecycle and JSONL protocol for multi-language SDKs through a unified abstraction.
+- Provides consistent interfaces for session scheduling, permission governance, Hook/MCP callbacks, logging, and metrics collection.
+- Aligns protocol specifications with the Claude Agent SDK to reduce collaboration costs and ecosystem integration friction across platforms.
+
+## Architecture Overview
+
+| Layer | Key Components | Responsibility Highlights |
+| --- | --- | --- |

+
+- The Agent SDK and CLI share a bidirectional STDIN/STDOUT JSONL channel that transports events such as `chat.completion*`, `result/*`, and `control_request`.
+- Event flow: the CLI writes `chat.completion`/`result/*`/`control_request` line-by-line to stdout; the SDK parses them and, when needed, writes `request`/`control_response` back to stdin. When a `control_request{subtype:"mcp_message"}` appears, the ControlPlane forwards the JSON-RPC payload to the local MCP server and relays the resulting `mcp_response`.
+- The qwen-code CLI already integrates with OpenTelemetry to report model calls, tool executions, and internal events; the Agent SDK must instrument independently and propagate trace/span IDs across the entire path to build a unified troubleshooting view.
+- Control protocol semantics align with the CLI output format specification, as documented in the accompanying `stream-json` RFC.
+- For details on event categories such as `result/*`, `request`, and `control_request`, refer to the “Event Classification” section of `qwen-code-cli-output-format-stream-json-rfc_cn.md`.
+
+## Core Capability Mapping
+
+| Capability Domain | Key Focus | Current Capability | Future Evolution |
+| --- | --- | --- | --- |
+| Session Scheduling | Session routing, worker binding, reuse strategies | Router and worker pool scheduling provided by the SDK | Enhance session branching and sub-agent scheduling |
+| Process Governance | Subprocess launch, monitoring, restart | ProcessMgr oversees lifecycle and resource limits | Introduce resource quotas and automatic fault isolation |
+| Control Protocol | Permission callbacks, hooks, MCP | ControlPlane handles `control_request` uniformly | Expand hook points and approval strategies |
+| IPC Protocol | JSON Lines, input/output formats | IPC layer implements `stream-json` / `stream-chunk-json` | Enrich event types and support protocol negotiation |
+| Observability | Logging, metrics, tracing | SDK and CLI both integrate OTel and emit structured logs | Standardize metric names and cross-component trace analysis |
+
+- The scheduling and control layers must enforce worker exclusivity, session isolation, and resource reclamation.
+- The control protocol follows a request/response model; the SDK must return a `control_response` before timeout to prevent the CLI from blocking.
+
+## Agentic Session Capabilities
+
+| Capability Block | Design Focus | Interface / Structure |
+| --- | --- | --- |
+| Session Loop | Stateful `QwenAgentClient`, separating connection and message flow phases | `connect()`, `disconnect()`, `Query.initialize()` |
+| Session Context | Support async context management and resource teardown | `__aenter__` / `__aexit__`, `async with QwenAgentClient` |
+| Message Flow Handling | Append inputs and consume streaming outputs within the same session | `query()`, `stream_input()`, `receive_messages()`, `receive_response()` |
+| Dynamic Control | Switch models/permissions at runtime, trigger interrupts, retrieve initialization data | `interrupt()`, `set_permission_mode()`, `set_model()`, `get_server_info()` |
+| Transport Abstraction | Pluggable transports for local/remote CLI and buffered daemons | `Transport`, `SubprocessCLITransport`, `max_buffer_size` validation |
+
+### Session Loop and Context
+
+- `QwenAgentClient.connect()` supports both string and async stream modes. Hooks and the SDK MCP server can be injected during the first `initialize` call to ensure multi-turn sessions across IDEs and services.
+- `disconnect()` clears `_query` and the transport. Combined with `async with`, it automates connection/disposal to avoid orphaned subprocesses.
+- Parameter validation should proactively reject mutually exclusive options (for example, enabling both `can_use_tool` and `permission_prompt_tool_name`) to improve configuration ergonomics.
+
+### Message Flow Handling
+
+- `query()` automatically fills `session_id` and writes JSONL records, allowing scripts and UIs to append messages as needed.
+- `stream_input()` handles incremental writes, clears buffers on exceptions, and records debug logs to stabilize long-running flows.
+- `receive_messages()` iterates over every event, while `receive_response()` stops as soon as it encounters a `ResultMessage`, helping UIs detect when a single response completes.
+- The `include_partial_messages` option forwards incremental chunks. Combined with `stderr`/`debug_stderr`, it captures low-level diagnostics for real-time rendering in complex interfaces.
+
+### Dynamic Control Interfaces
+
+- `_send_control_request` supports subtypes such as `interrupt`, `set_permission_mode`, and `set_model`, enabling manual interruption, permission mode switching, and hot model changes.
+- `get_server_info()` fetches CLI initialization capabilities (protocol versions, command set, etc.) for dynamic front-end or policy configuration.
+- `async query(...)->AsyncIterator` exposes a script-friendly interface that consumes the entire response in one go while preserving the ability to swap in custom transports.
+
+### Single-Query and Multi-Agent Orchestration
+
+- `query()` wraps the session lifecycle for rapid integrations such as scripts or batch tasks. When a custom `Transport` is provided, remote CLIs or agent services can be reused.
+- The `agents` configuration maps multi-agent topologies onto the CLI `--agents` flag. In conjunction with `fork_session`, it supports session branching and sub-agent routing.
+- When generating CLI commands, the SDK must compose JSON payloads for options such as `setting_sources`, `allowed_tools`, and `mcp_servers` to ensure feature parity with the CLI.
+
+### Hooks and MCP Bridging
+
+- During initialization, hook definitions convert the `HookMatcher` list into `hookCallbackIds`. Subsequent `hook_callback` events use those IDs to invoke host logic at critical stages such as `PreToolUse`, `PostToolUse`, and `UserPromptSubmit`.
+- On the SDK side, `create_sdk_mcp_server` / `defineTools` build an MCP server inside the host process. `mcp_message` requests trigger JSON-RPC procedures (`tools/list`, `tools/call`, `initialize`, etc.) without spawning extra subprocesses.
+- Permission approvals are returned via `PermissionResultAllow` / `PermissionResultDeny` and `PermissionUpdate`, enabling fine-grained policies that can be adjusted in hooks or tool callbacks.
+- **Example: Combining PreToolUse and UserPromptSubmit** (based on `third-party/anthropics/claude-agent-sdk-python/examples/hooks.py`):
+ ```python
+ import asyncio
+ from qwen_agent_sdk import HookContext, HookMatcher, QwenAgentOptions, QwenSDKClient
+
+
+ async def block_risky_bash(
+ input_data: dict[str, object],
+ tool_use_id: str | None,
+ context: HookContext,
+ ) -> dict[str, object]:
+ command = input_data.get("command", "") if isinstance(input_data, dict) else ""
+ if isinstance(command, str) and "rm -rf" in command:
+ return {
+ "hookSpecificOutput": {
+ "hookEventName": "PreToolUse",
+ "permissionDecision": "deny",
+ "permissionDecisionReason": "Block dangerous delete command.",
+ }
+ }
+ return {}
+
+
+ async def inject_user_memory(
+ input_data: dict[str, object],
+ tool_use_id: str | None,
+ context: HookContext,
+ ) -> dict[str, object]:
+ return {
+ "hookSpecificOutput": {
+ "hookEventName": "UserPromptSubmit",
+ "additionalContext": "Remember that the user's favorite color is blue.",
+ }
+ }
+
+
+ options = QwenAgentOptions(
+ allowed_tools=["Bash"],
+ hooks={
+ "PreToolUse": [HookMatcher(matcher="Bash", hooks=[block_risky_bash])],
+ "UserPromptSubmit": [HookMatcher(matcher=None, hooks=[inject_user_memory])],
+ },
+ )
+
+
+ async def main() -> None:
+ async with QwenSDKClient(options=options) as client:
+ await client.query("Try to run: rm -rf /tmp")
+ async for message in client.receive_response():
+ ...
+
+
+ asyncio.run(main())
+ ```
+
+### Transport Layer Extensions
+
+- The `Transport` abstraction makes it possible to replace the default `SubprocessCLITransport` for remote CLI, agent service, or container-hosted scenarios.
+- Before the handshake, the transport performs version checks and enforces `max_buffer_size`; when output exceeds the limit it raises a structured error and cleans buffers to prevent memory bloat.
+- Options can specify working directory, environment variables, and stderr capture to support IDE integration and server deployments flexibly.
+- `SubprocessCLITransport` must inject CLI arguments such as `--mcp-config`, `--agents`, and `--setting-sources`, and set environment variables like `CLAUDE_CODE_ENTRYPOINT` plus custom `env` and `user` values to keep subprocess capabilities aligned.
+- **Example: Custom Remote Transport** (see `third-party/anthropics/claude-agent-sdk-python/src/claude_agent_sdk/_internal/transport/__init__.py`):
+ ```python
+ import json
+ from collections.abc import AsyncIterator
+ import httpx
+ from qwen_agent_sdk import QwenAgentOptions, QwenSDKClient
+ from qwen_agent_sdk.transport import Transport
+
+
+ class RemoteHTTPTransport(Transport):
+ def __init__(self, endpoint: str) -> None:
+ self._client = httpx.AsyncClient(base_url=endpoint, timeout=30.0)
+ self._ready = False
+
+ async def connect(self) -> None:
+ self._ready = True
+
+ async def write(self, data: str) -> None:
+ await self._client.post("/ingress", content=data.encode("utf-8"))
+
+ def read_messages(self) -> AsyncIterator[dict[str, object]]:
+ async def iterator() -> AsyncIterator[dict[str, object]]:
+ async with self._client.stream("GET", "/egress") as response:
+ async for line in response.aiter_lines():
+ if line:
+ yield json.loads(line)
+ return iterator()
+
+ async def close(self) -> None:
+ await self._client.aclose()
+ self._ready = False
+
+ def is_ready(self) -> bool:
+ return self._ready
+
+ async def end_input(self) -> None:
+ await self._client.post("/ingress/close")
+
+
+ transport = RemoteHTTPTransport("https://cli-gateway.internal")
+ options = QwenAgentOptions(system_prompt="Execute every command through the remote CLI gateway.")
+
+
+ async with QwenSDKClient(options=options, transport=transport) as client:
+ await client.query("Read README.md and summarize three highlights.")
+ async for message in client.receive_response():
+ ...
+ ```
+
+### Debugging and Environment Injection
+
+- CLI orchestration must derive the full command list from `QwenAgentOptions`, distinguishing between streaming (`--input-format stream-json`) and single-shot (`--print`) execution.
+- `options.stderr` and `debug_stderr` let the SDK capture CLI diagnostic output, while anyio `TaskGroup` consumes stderr streams in real time.
+- Parameters such as `cwd`, `env`, and `user` determine the subprocess working directory and permission boundaries; the SDK should pass them explicitly at startup and reclaim resources on disconnect.
+- **Example: Error Callback and Retry** (see `third-party/claude-agent-sdk-python-demo/add_my_permission.py`):
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ PermissionDecision,
+ PermissionRequest,
+ PermissionUpdate,
+ QwenAgentOptions,
+ QwenSDKClient,
+ )
+
+

+ return PermissionDecision(allow=False, reason="Reject commands that may break work.")
+ return PermissionDecision(allow=True, updates=[PermissionUpdate(mode="allow")])
+

+
+### Python SDK Details
+
+- **Runtime and Distribution**: Requires Python 3.10+; distributed via `pyproject.toml + hatchling`; provides the `qwen_agent_sdk` namespace plus `py.typed`.
+- **Environment Dependencies**: Node.js and the `qwen-code` CLI must be installed. Before startup the SDK locates the binary via `which qwen` or the `QWEN_BIN` environment variable.
+- **Core Dependencies**: `anyio>=4`, `typing_extensions`, `mcp>=0.1`, `pydantic>=2`.
+- **Typical Scenarios**: Third-party backend services that need customized experiences or server-side execution.
+- **API Design**:
+ - `async def query(...) -> AsyncIterator[Message]`: Aligns with Anthropic’s streaming `query()` interface.
+ - `class QwenSDKClient`: Supports `async with`, session continuation, and interruption management.
+ - `QwenAgentOptions`: Includes parameters such as `system_prompt`, `setting_sources`, `permission_mode`, `cwd`, and `fork_session`.
+ - `@tool` decorator + `create_sdk_mcp_server`: Register Python functions as MCP tools.
+- **Implementation Highlights**:
+ - `StdIOSubprocessTransport` launches the `qwen` CLI, writes JSONL, and reads streaming chunks.
+ - `_handle_control_request()` processes subtypes such as `can_use_tool`, `hook_callback`, and `mcp_message`, writing back corresponding `control_response`.
+ - **Hook System**: Supports events such as `PreToolUse`, `PostToolUse`, and `UserPromptSubmit`. Returns JSON instructions to adjust the session flow, mirroring Anthropic’s hook JSON structure.
+ - `Query.initialize()` sends an initial `control_request{subtype:"initialize"}` to synchronize hook configuration and capability declarations.
+ - Unifies `PermissionResult`, hook JSON, and MCP JSON-RPC payloads under a consistent abstraction.
+- **Logging and Observability**:
+ - Emits structured JSON logs by default and supports injecting a `structlog` logger.
+ - **Lightweight Logging Convention**: Follow standard `logging`-style structured JSON output. `options.stderr`/`debug_stderr` can capture raw CLI error streams for faster troubleshooting.
+ - Plans to bundle OpenTelemetry tracer/meter instrumentation for session latency, transport errors, and worker utilization.
+- **Resilience**:
+ - Implements retries and backoff for transient transport failures.
+ - Guards against buffer overflows by leveraging `max_buffer_size`.
+ - Gracefully degrades when CLI capabilities are missing, surfacing actionable errors.
+- **Examples**:
+ - **Streaming Query with Cost Tracking** (adapted from `third-party/anthropics/claude-agent-sdk-python/examples/basic_stream.py`):
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ QwenSDKClient,
+ ResultMessage,
+ query,
+ )
+
+
+ async def main() -> None:
+ options = QwenAgentOptions(model="qwen3-coder-plus")
+ async for message in query(prompt="What is 2 + 2?", options=options):
+ if isinstance(message, AssistantMessage):
+ for block in message.content:
+ if hasattr(block, "text"):
+ print(block.text)
+ elif isinstance(message, ResultMessage) and message.total_cost_usd:
+ print(f"Spent this round: ${message.total_cost_usd:.4f}")
+
+
+ anyio.run(main)
+ ```
+ - **Multi-Agent and Setting Sources** (see `third-party/anthropics/claude-agent-sdk-python/examples/agents.py` and `.../setting_sources.py`):
+ ```python
+ from qwen_agent_sdk import AgentDefinition, QwenAgentOptions, query
+
+
+ options = QwenAgentOptions(
+ agents={
+ "doc-writer": AgentDefinition(
+ description="Produce structured documentation.",
+ prompt="You are a senior documentation engineer. Explain with clear steps.",
+ tools=["Read", "Write"],
+ ),
+ "tester": AgentDefinition(
+ description="Generate and run tests.",
+ prompt="You are responsible for authoring tests and verifying outcomes.",
+ tools=["Read", "Write", "Bash"],
+ ),
+ },
+ setting_sources=["user", "project"],
+ )
+
+
+ async for message in query(
+ prompt="Invoke doc-writer to explain what AgentDefinition is for.",
+ options=options,
+ ):
+ ...
+ ```
+ - **Embedded MCP Tool** (see `third-party/anthropics/claude-agent-sdk-python/examples/mcp_calculator.py`):
+ ```python
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ QwenSDKClient,
+ TextBlock,
+ create_sdk_mcp_server,
+ tool,
+ )
+
+
+ @tool("add", "Calculate the sum of two numbers.", {"a": float, "b": float})
+ async def add_numbers(args: dict[str, float]) -> dict[str, object]:
+ total = args["a"] + args["b"]
+ return {"content": [{"type": "text", "text": f"{args['a']} + {args['b']} = {total}"}]}
+
+
+ calculator = create_sdk_mcp_server(
+ name="calculator",
+ version="1.0.0",
+ tools=[add_numbers],
+ )
+
+
+ options = QwenAgentOptions(
+ mcp_servers={"calc": calculator},
+ allowed_tools=["mcp__calc__add"],
+ )
+
+
+ async with QwenSDKClient(options=options) as client:
+ await client.query("Call mcp__calc__add to compute 6 + 7.")
+ async for message in client.receive_response():
+ if isinstance(message, AssistantMessage):
+ for block in message.content:
+ if isinstance(block, TextBlock):
+ print(block.text)
+ else:
+ ...
+ ```
+
+### TypeScript SDK Details
+
+- **Runtime and Distribution**: Requires Node.js 18+. Package name `@qwen-agent/sdk` exports ESM by default and exposes CJS via `exports`. Uses `tsup` to generate `dist/esm`, `dist/cjs`, and `dist/types`.
+- **Core Dependencies**: `@qwen-code/cli` (peer dependency), `zx/execa`, `eventemitter3`.
+- **API Capabilities**:
+ - `createAgentManager(options)`: Provides `createSession`, `run`, and `forkSession`.
+ - `session.stream(task)`: Returns `AsyncIterable` for consumption with `for await`.
+ - `onPermissionRequest`: Returns permission decisions using `allow` / `deny` / `ask` plus associated rules.
+ - `settingSources`: Disabled by default; explicitly declare entries like `["user", "project", "local"]` to load corresponding settings files.
+ - `defineTools`: Registers MCP tools that share context with CLI sessions.
+ - `agents` option: Supports inline multi-agent topologies; combine with `forkSession` to orchestrate sub-agents.
+- **Implementation Notes**:
+ - Launches the CLI via `execa` and parses stdout uniformly as `AgentStreamChunk`.
+ - `ProcessTransport` decodes stdout line by line (`JSON.parse`) and relays `control_request`, `result/*`, and `chat.completion*` events through `EventEmitter`, while sending all `control_response` payloads through stdin.
+ - Maintains a `result/heartbeat` timer that automatically restarts workers on timeout.
+ - The `pendingControl` map uses `request_id` to route `control_request` callbacks.
+ - Callback promises create normalized `control_response` payloads; unregistered callbacks fall back to defaults.
+ - `onPermissionRequest` and `onHookEvent` resolve to promises that generate `control_response`. If no callback is registered, the system keeps using default policies to avoid blocking the CLI.
+ - `defineTools()` packages TypeScript functions into an in-process MCP server and forwards JSON-RPC calls.
+ - During initialization, the SDK waits for the CLI’s first `chat.completion` handshake, then sends hook/tool capabilities via `control_request{subtype:"initialize"}`.
+ - Exceptional cases log verbose diagnostics and return `control_response{subtype:"error"}`.
+- **Engineering System**:
+ - `tsup` produces `dist/esm`, `dist/cjs`, and `dist/types`.
+ - Test matrix uses `vitest` + `tsx` combined with CLI mocks to verify streaming output and permission callbacks.
+ - Exposes `enableVerboseLogging()`, `logger` / `stderr` callbacks, and plans to integrate OpenTelemetry tracing.
+
+### Other Language Plans (TODO)
+
+- **Go / Java**: Intend to reuse the unified control protocol and worker scheduling strategy, targeting enterprise and backend scenarios.
+- Detailed SDK designs and implementations will follow once the Python/TypeScript versions stabilize.
+
+## Control Protocol and MCP Integration
+
+| Channel | Initiator | Typical Events | Response Requirement | Purpose |
+| --- | --- | --- | --- | --- |
+| `chat.completion*` | CLI → SDK | Model replies, tool invocations, closing summaries | No response required | Carries the primary conversation |
+| `result/*` | CLI → SDK | `result/command`, `result/heartbeat`, `result/cancel`, `x-qwen-session-event` | No response required | Publishes status and auxiliary info |
+| `*request` | SDK → CLI | `command_hint_request`, `heartbeat_request`, `control/cancel` | CLI responds with `result/*` | Triggers immediate operations |
+| `control_request` | CLI → SDK | `can_use_tool`, `hook_callback`, `mcp_message` | Must return `control_response` | Executes permission checks, hooks, MCP calls |
+
+- All control events travel through the shared STDIN/STDOUT pipes, and the SDK must respond within the agreed timeout.
+- MCP integration builds the server inside the SDK process, eliminating extra subprocesses or network services.
+- Authorization callbacks and MCP calls remain decoupled: the CLI still emits `can_use_tool`, the SDK handles permission logic, and only then processes `mcp_message`.
+
+```mermaid
+sequenceDiagram
+ participant CLI as qwen-code CLI (stdout/stdin)
+ participant Control as Agent SDK ControlPlane
+ participant MCP as In-Process MCP Server
+ participant Tool as User-Defined Tool
+
+ CLI->>Control: control_request (subtype="mcp_message", stdout)
+ Control->>MCP: JSON-RPC (tools/list | tools/call)
+ MCP->>Tool: Invoke async handler
+ Tool-->>MCP: Return result
+ MCP-->>Control: jsonrpc result (mcp_response)
+ Control-->>CLI: control_response (stdin)
+```
+
+- During initialization, `control_request{subtype:"initialize"}` synchronizes hook configuration and capability declarations.
+- When callbacks throw, the SDK must log the failure and return `control_response{subtype:"error"}` so the CLI can safely fall back.
+
+| `control_request.subtype` | Key Input | SDK Response Constraints | Notes |
+| --- | --- | --- | --- |
+| `initialize` | Includes `hooks` config and optional MCP capability declarations | Return `control_response` confirming success or failure; persist `_initialization_result` | Map `HookMatcher` callbacks to `hookCallbackIds` for later invocation |
+| `can_use_tool` | Provides `tool_name`, `input`, `permission_suggestions` | Return `behavior=allow/deny`, optionally `updatedInput`, `updatedPermissions` | `updatedPermissions` is an array of `PermissionUpdate`, supporting rule, directory, and mode adjustments |
+| `hook_callback` | Supplies `callback_id` and hook context | Look up and execute the matching callback, then return JSON | Cache callback mappings during connection; missing entries must yield structured errors |
+| `mcp_message` | Provides `server_name` and JSON-RPC `message` | Call the SDK’s MCP server and wrap the `mcp_response` | Supports standard methods (`initialize`, `tools/list`, `tools/call`); failures must return JSON-RPC error objects |
+
+- `PermissionUpdate` supports `addRules`, `replaceRules`, `removeRules`, `setMode`, `addDirectories`, `removeDirectories`, etc. The SDK must forward rule content and directory sets precisely to satisfy enterprise-grade governance.
+- Hook configuration allows multiple events and matchers. `HookMatcher.matcher` specifies matching conditions, `hooks` lists callbacks, and the SDK generates callback IDs during initialization to route later `hook_callback` executions.
+
+## Communication Model and MCP Capabilities
+
+| Module | Form | Key Notes |
+| --- | --- | --- |
+| IPC Mode | STDIN/STDOUT JSON Lines | The SDK launches a local `qwen` subprocess and exchanges JSON Lines. Protocol details follow `qwen-code-cli-output-format-stream-json-rfc_cn.md`, preserving instant replies for `/`, `@`, and `?` commands. |
+| In-Process MCP Server | SDK-embedded MCP server | Relies on `mcp>=0.1` to create an MCP server inside the host process, forwarding functions defined via `@tool` / `defineTools` without additional subprocesses or network hops. |
+
+- **IPC Implementation Highlights**:
+ - `SubprocessCLITransport` (or equivalent) handles both directions over the same STDIN/STDOUT pipes—no extra sockets required.
+ - When the CLI emits `chat.completion` / `chat.completion.chunk`, the first message’s `metadata` must carry `protocol_version`, `input_format`, `output_format`, and `capabilities`.
+ - Event semantics cover `result/heartbeat`, `result/cancel`, `x-qwen-session-event`, and `control_request/control_response`, and expose OpenAI-style error objects.
+- **MCP Event Flow**:
+ - The CLI writes JSON-RPC payloads via `control_request{subtype:"mcp_message"}`. The SDK forwards them to the local MCP server, which handles `tools/list` / `tools/call`.
+ - Results are wrapped in `control_response` and written back to stdin to complete the loop.
+- **Authorization Responsibilities**:
+ - The CLI emits `control_request{subtype:"can_use_tool"}` while the SDK decides authorization, keeping MCP invocation separate from permission checks.
+ - Executing tools inside the SDK process reduces latency. Hook capabilities can share the same channel, consistent with Claude Agent SDK practices.
+
+## Worker Pool and Reuse
+
+| Dimension | Design Highlights | Implementation Status |
+| --- | --- | --- |
+| State Machine | Idle → Busy → Idle, each worker exclusively serves a session | Designed |
+| Reuse Strategy | Retain processes after sessions, clean context, and reuse | Planned rollout |
+| Safety | Session isolation, resource cleanup, health checks | Delivered alongside the worker pool |
+| Configuration | `min_workers`, `max_workers`, `idle_timeout`, `max_sessions_per_worker`, `health_check_interval` | Must be exposed in SDK/CLI configs |
+| Observability | Structured logs, metric export, trace linkage | SDK and CLI instrument independently |
+
+- **Environment**: Workers are qwen-code CLI subprocesses. Containers/sandboxes and tool bridging are handled by the CLI, while the SDK only schedules via STDIN/STDOUT.
+- Each worker is exclusive to a session. When the session ends, the worker returns to the idle pool.
+- Reuse depends on clearing session variables, closing file handles, and resetting environment variables.
+- Health checks watch for memory leaks, zombie processes, and deadlocks. Failures trigger automatic restarts.
+- Example configuration:
+
+```yaml
+worker_pool:
+ min_workers: 5
+ max_workers: 50
+ idle_timeout: 1800 # 30 minutes
+ max_sessions_per_worker: 100
+ health_check_interval: 60
+```
+
+- Session logs should record `session_id`, `prompt_id`, elapsed time, and command summaries, then feed centralized logging.
+- Metrics focus on active/idle counts, queue latency, restart counts, and failure rates. Traces must propagate across SDK → CLI → tool calls.
+
+## Configuration Injection and Settings Management
+
+| Item | Capability | Notes |
+| --- | --- | --- |
+| `settings_profile` | Assign an isolated configuration per `QwenClient` | Affects the worker pool and subprocesses owned by that client |
+| `system/system_defaults` | Provide an absolute path or JSON overrides | Mapped to CLI environment variables such as `QWEN_CODE_SYSTEM_SETTINGS_PATH` |
+| `user/workspace` | JSON objects or file/directory paths | SDK generates `settings.json` in a temporary directory and mounts it for the CLI |
+| `overrides` | Key-value overrides such as `model.name`, `tools.allowed` | Written directly into the temporary config file |
+
+- **Ecosystem Reuse**: Inherits the CLI’s multi-layer settings hierarchy (`SettingScope.System/SystemDefaults/User/Workspace`). Each `QwenClient` is isolated, and when no profile is provided the CLI follows its default loading order.
+- **Implementation Steps**:
+ 1. Add a `settings_profile` field to `QwenClientOptions` / `QwenAgentOptions` across Python and TypeScript SDKs.
+ 2. Before launching CLI workers, write the profile into an isolated directory and configure `--setting-sources` / `--settings` (or equivalent flags).
+ 3. Set environment variables such as `QWEN_CODE_USER_SETTINGS_PATH` and `QWEN_CODE_WORKSPACE_SETTINGS_PATH` to point at the generated temporary files.
+ 4. Remove the temporary directory when the worker pool shuts down to prevent configuration leakage.
+- **Logging and Troubleshooting**: Emit redacted profile summaries in logs to diagnose configuration mismatches.
+- **Security Considerations**: Only the host application injects configuration—no fallback to shared paths—to prevent cross-tenant contamination. Sensitive tokens and paths must be safeguarded.
+- **Compatibility**: The CLI must parse the new environment variables and safely ignore unrecognized keys.
+- **Current Status Reminder**: The CLI has not yet implemented per-subprocess configuration. Future RFCs/PRs must deliver `--settings-profile` and related environment variable support.
+
+## Agent SDK Orchestration Capabilities
+
+| Module | Core Responsibility | Current Status | Next Steps |
+| --- | --- | --- | --- |
+| IPC Wrapper | Parse/write JSON Lines, route events | CLI still uses plain-text STDIN and needs enhancement | Introduce `StdinReaderService`, `StdoutWriterService`, and strengthen `main()` |
+| Process Management | Launch, monitor, enforce resource limits, log | Initial design | Establish resource quotas and automatic restart policies |
+| Control Protocol | Permission callbacks, hook injection | CLI only exposes ApprovalMode | Add permission APIs, hook system, and instrumentation |
+| Input/Output Formats | `--input-format` / `--output-format` | CLI must support `stream-json` | Complete argument parsing and auto-disable TUI |
+| Event Semantics | `result/heartbeat`, `control_request`, etc. | Under definition | Implement aligned with the CLI output format RFC |
+
+- `docs/ipc/qwen-chat-request-schema.json` extends OpenAI `/chat/completions` by adding `session_id`, `prompt_id`, `origin`, and `tool_call_id`.
+- Error semantics must match the CLI output format: fatal errors emit OpenAI-style error objects, while recoverable errors use `chat.completion`.
+- Immediate responses and event dispatch are required for `/`, `@`, and `?` command requests.
+
+## Observability and Debugging
+
+| Area | Highlights |
+| --- | --- |
+| Logging | SDK writes structured JSON by default; the CLI can forward stderr and supports injecting a `logger` |
+| Metrics | SDK/CLI expose active workers, queue latency, error counts, etc., with a plan to standardize metric names |
+| Trace | Create session-level spans, propagate through CLI and tool invocation chains, and enable end-to-end troubleshooting |
+| Debugging Tools | TypeScript offers `enableVerboseLogging()`, Python captures `debug_stderr`, and both plan to integrate OTel |
+
+- Third-party services should record message sequences to support auditing and replay.
+- CLI command samples can be reused for local debugging (see the output format RFC).
+
+## Integration Model
+
+| Pattern | Applicable Scenarios | Key Traits |
+| --- | --- | --- |
+| Host Process Integrates SDK | IDE plugins, enterprise tools, CLI extensions | Launch worker pools inside the host process, communicate with the CLI via IPC JSONL, support synchronous and streaming output |
+
+**Quick Start Example**:
+
+```python
+from qwen_agent_sdk import QwenClient
+
+with QwenClient(binary_path="qwen", model="qwen3-coder-plus") as client:
+ result = client.chat(
+ task="Scan main.py for potential bugs and fix them.",
+ workspace="/repos/demo"
+ )
+ print(result.summary)
+```
+
+- Third-party applications can rely on `qwen-agent-sdk` to manage sessions, tools, and permission policies uniformly.
+- The SDK must support session replay and cancellation, heartbeat maintenance, and timeout control.
+- **Example: All-in-One Session Scaffold** (see `third-party/claude-agent-sdk-python-demo/quick_start_example.py`):
+ ```python
+ import anyio
+ from qwen_agent_sdk import (
+ AssistantMessage,
+ QwenAgentOptions,
+ QwenSDKClient,
+ TextBlock,
+ create_sdk_mcp_server,
+ query,
+ tool,
+ )
+
+
+ @tool("get_system_info", "Retrieve system information.", {})
+ async def get_system_info(_: dict[str, object]) -> dict[str, object]:
+ import os
+ import platform
+
+ summary = "\n".join(
+ [
+ f"- OS: {platform.system()} {platform.release()}",
+ f"- Python version: {platform.python_version()}",
+ f"- Current directory: {os.getcwd()}",
+ ]
+ )
+ return {"content": [{"type": "text", "text": summary}]}
+
+
+ async def run_all_examples() -> None:
+ # 1) Basic Q&A
+ async for msg in query(prompt="Hello, introduce yourself."):
+ if isinstance(msg, AssistantMessage):
+ for block in msg.content:
+ if isinstance(block, TextBlock):
+ print(block.text)
+
+ # 2) Custom parameters + streaming
+ options = QwenAgentOptions(system_prompt="You are an experienced assistant. Respond step by step.")
+ async for msg in query("Explain the difference between multiprocessing and multithreading.", options=options):
+ ...
+
+ # 3) Register custom tools
+ server = create_sdk_mcp_server(name="my-tools", version="1.0.0", tools=[get_system_info])
+ async with QwenSDKClient(
+ options=QwenAgentOptions(
+ mcp_servers={"tools": server},
+ allowed_tools=["mcp__tools__get_system_info"],
+ )
+ ) as client:
+ await client.query("Fetch the current runtime environment.")
+ async for msg in client.receive_response():
+ ...
+
+
+ anyio.run(run_all_examples)
+ ```
+
+## Open Items and Future Work
+
+| Direction | Pending Tasks |
+| --- | --- |
+| CLI Protocol Support | Complete `stream-json` input/output, event semantics, and handshake metadata |
+| Control Protocol | Implement permission callback APIs, hook instrumentation, MCP `mcp_message` pathway |
+| Worker Pool | Improve health checks, resource quotas, and automatic fault isolation |
+| Configuration System | Add CLI support for `--settings-profile` and related environment variables |
+| Multi-Language SDKs | Expand Go/Java versions, build a unified test matrix and documentation |
+| Observability | Jointly define metric names and trace sampling strategies, refine logging guidelines |

+> **双向通信说明**:
+> - Agent SDK 与 qwen-code CLI 共用 STDIN/STDOUT 建立双向 JSONL 通道。
+> - CLI 将 `chat.completion`/`result/*` 及 `control_request` 等事件 (比如工具权限请求、MCP 调用) 逐行写入 stdout。
+> - SDK 读取事件后, 视需求通过 stdin 写回 `request`/`control_response` 等控制消息, 保持状态一致。
+> - 当事件拓展为 `control_request` 内的 `subtype:"mcp_message"`（规划中, 参考 Claude 控制协议）时, ControlPlane 会把 JSON-RPC 转发给 In-Process MCP Server 执行对应工具, 再把 `mcp_response` 封装进 `control_response` 回传 CLI, 形成闭环。
+

+
+## 关键组件说明
+
+### 1. Qwen-Code Agent Client SDK
+
+- **多语言支持**:
+ - `qwen-agent-sdk` (Python): 首发绑定, 复用 TypeScript 控制协议并提供 Pythonic API
+ - `qwen-agent-sdk` (TypeScript): 核心实现, 提供子进程编排与控制协议能力
+ - `qwen-agent-sdk` (Go): TODO
+ - `qwen-agent-sdk` (Java): TODO
+
+- **适用场景**:
+ - 第三方后端服务集成
+ - 希望自定义交互层体验的场景
+ - 服务端到服务端调用
+
+- **核心功能**:
+- 同步/异步任务执行
+- 流式输出
+- 会话管理
+- 错误处理与重试
+- In-Process MCP Server 工具桥接
+- 独立配置注入
+
+#### 通信模式
+
+- **IPC 模式**: SDK 启动本地 `qwen` 子进程,以 JSON Lines 协议进行进程间通信。
+
+> 📘 IPC 模式的协议与最新 CLI IPC 草案详见《qwen-code-cli-output-format-stream-json-rfc_cn.md》。
+
+#### In-Process MCP Server
+
+- **形态**: SDK 依赖 `mcp>=0.1` 在宿主进程内创建 MCP Server, 将通过 `@tool`/`defineTools` 定义的函数注册为工具, 无需额外子进程或网络服务。
+- **事件链路**: 当 CLI 输出（或后续扩展为） `control_request` 内的 `subtype:"mcp_message"` 事件到 stdout 时, SDK 把 JSON-RPC 内容转发给本地 MCP Server 执行 `tools/list`、`tools/call` 等操作, 并把结果封装为 `control_response` 回写 stdin。
+- **授权分工**: 工具执行前的授权仍由 CLI 触发 `control_request{subtype:"can_use_tool"}` 等事件并交由 SDK 回调处理, 与 MCP 调用链路解耦, 保持权限判定的独立性。
+- **优势**: 在保持 CLI 原有授权/审批流程不变的前提下, 将工具执行搬到 SDK 进程内以降低延迟; Hook 能力仍待 CLI 侧落地后再沿同一通路接入。整体方案与 Claude Agent SDK 的 In-Process 实践对齐, 便于多语言同步拓展。
+
+#### 独立配置注入 (每个 QwenClient)
+
+- **能力概述**: 允许第三方在创建 `QwenClient` 时可选提供一份针对该客户端的 qwen-code 设置配置 (`settings_profile`), 仅影响该客户端维护的 Worker 池及其衍生子进程。
+- **作用范围**: 生态复用 CLI 的多层设置体系 (`SettingScope.System/SystemDefaults/User/Workspace`), 但不同 `QwenClient` 间相互隔离; 未提供 `settings_profile` 时, CLI 按既有规则从系统/用户/项目路径加载。
+- **形态**:
+ - `settings_profile.system` / `system_defaults`: 绝对路径或 JSON overrides, 映射到 CLI 中 `QWEN_CODE_SYSTEM_SETTINGS_PATH` / `QWEN_CODE_SYSTEM_DEFAULTS_PATH` (见 `packages/cli/src/config/settings.ts`)。
+ - `settings_profile.user` / `workspace`: 可传入 JSON 对象或指向文件/目录; SDK 会在临时目录生成 `settings.json`, 并通过新引入的环境变量 (如 `QWEN_CODE_USER_SETTINGS_PATH`, `QWEN_CODE_WORKSPACE_SETTINGS_PATH`) 或 CLI `--settings-profile` 选项挂载到子进程。
+ - `settings_profile.overrides`: 额外键值对, 直接写入生成的临时配置文件, 用于快速覆盖单个字段 (如 `model.name`, `tools.allowed`)。
+- **实现要点**:
+ 1. `QwenClientOptions`/`QwenAgentOptions` 同步新增 `settings_profile` 字段, Python/TypeScript SDK 均支持。
+ 2. 在 Worker 池启动 CLI 前, 根据 profile 将配置写入隔离目录, 设置所需环境变量并更新 `--setting-sources` / `--settings` 参数。
+ 3. Worker 池销毁时负责清理临时目录, 避免配置泄漏。
+ 4. 日志中打印 profile 摘要 (不含敏感字段), 便于排查配置错配。
+- **安全考量**: 配置仅由宿主应用传入, SDK 不自动回退到共享路径; 避免跨租户污染。需在文档中提示敏感字段 (Token/路径) 应妥善管理。
+- **兼容性**: CLI 未定义的环境变量需在 CLI 端补齐解析逻辑, 并回退到默认行为 (忽略未知变量)。
+- **实施备注**: 目前 qwen-code CLI 尚未支持针对单个子进程注入独立配置。该能力需另行提交 CLI 端 RFC 与 PR(例如新增 `--settings-profile` 参数及相关环境变量), 在 CLI 实现完成后 SDK 方可落地。

+from qwen_agent_sdk import query, QwenAgentOptions
+
+async def main():
+ async for message in query(
+ prompt="扫描并修复 @main.py 中的潜在 bug",
+ options=QwenAgentOptions(cwd="/repos/demo")
+ ):
+ print(message)
+
+anyio.run(main)
+```
+
+## 各语言 SDK 技术选型
+
+### qwen-agent-sdk-python
+
+#### 运行时与分发
+
+- **语言要求**: Python 3.10+, 与 Anthropic Python SDK 一致, 保障 `typing.Annotated`, `match` 等语法可用。
+- **包结构**: 采用 `pyproject.toml` + `hatchling` 构建, 发布 `py.typed` 以提供类型提示, 命名空间为 `qwen_agent_sdk`。
+- **环境依赖**: 需预装 Node.js 与 `qwen-code` CLI, SDK 启动前通过 `which qwen` 或 `QWEN_BIN` 环境变量定位二进制。
+
+#### 核心依赖
+
+- `anyio>=4`: 与 Anthropic SDK 一致, 统一 async/await 事件循环并兼容 Trio。
+- `typing_extensions`: 兼容 3.10/3.11 的 `TypedDict`, `NotRequired` 能力。
+- `mcp>=0.1`: 复用 In-Process MCP Server 能力, 支持装饰器式工具定义。
+- `pydantic>=2` (新增): 用于严格校验 JSONL 消息、权限响应与 Hook payload。
+
+#### API 设计
+
+- **快速函数**: `async def query(...) -> AsyncIterator[Message]`, 语义与 Anthropic `query()` 对齐, 支持字符串与 `AsyncIterable` 输入。
+- **会话客户端**: `class QwenSDKClient`, 支持 `async with` 上下文、会话续写与中断, 暴露 `receive_response()` 流式读取。
+- **选项对象**: `QwenAgentOptions`, 对齐 TypeScript `AgentOptions`, 含 `system_prompt`, `setting_sources`, `permission_mode`, `cwd`, `fork_session`。
+- **工具注册**: `@tool` 装饰器 + `create_sdk_mcp_server`, 允许 Python 原生函数作为 CLI 工具。
+
+#### 技术实现要点
+
+- **Transport 抽象**: 提供 `StdIOSubprocessTransport`, 负责启动 `qwen` CLI、写入 JSONL、读取流式 chunk, 并将 CLI 事件映射为 Python 数据类。
+- **工具权限回调**: 暴露与 CLI `control_request{subtype:"can_use_tool"}` 对应的处理接口, 接收工具名、输入 payload 与上下文, 返回 `PermissionResult` 以告知允许/拒绝及补充规则。
+- **Hook 体系**: 支持 `PreToolUse`、`PostToolUse`、`UserPromptSubmit` 等事件, 允许返回 JSON 指令修改会话 (参考 Anthropic Hook JSON)。
+- **可插拔日志**: 提供基于 `structlog` 的观察性接口, 默认输出标准 JSON 日志, 支持注入自定义 logger。
+- **轻量日志约定**: 默认按 `logging` 标准输出结构化 JSON, 允许通过 `options.stderr`/`debug_stderr` 捕获 CLI 原始错误流, 满足快速排障需求。
+- **OpenTelemetry 接入**: 规划内置 OTel Tracer/Meter, 上报 SDK 自身的会话耗时、传输错误、Worker 利用率等指标, 与 CLI 侧指标解耦。
+- **错误恢复**: 针对 CLI 崩溃提供自动重试与会话 fork, 保存最后一次成功结果以便断点续传。
+
+#### 双向控制协议实现参考 (对齐 Claude Agent SDK)
+
+- **STDIO 对称信道**: 对齐《qwen-code-cli-output-format-stream-json-rfc_cn.md》定义的 `control_request`/`control_response` 语义, `SubprocessCLITransport` 始终通过同一 STDIN/STDOUT 管道处理正向/反向消息, 无需额外套接字。
+- **事件监听与解复用**: `Query._read_messages()` 按行读取 CLI 输出, 将 `type=control_request` 的 JSON 派发给 `_handle_control_request()`, 并通过 `pending_control_responses` + `request_id` 映射保证多请求并发时的正确回执。
+- **权限 / Hook / MCP 托管**: `_handle_control_request()` 将 `subtype` 映射到对应的回调: `can_use_tool` 触发 SDK 提供的权限协程, `hook_callback` 执行注册 Hook, 规划中的 `mcp_message` 事件则桥接到 in-process MCP Server (`tools/list`、`tools/call`、`initialize` 等)。处理结果统一写入 STDIN, 形成 `control_response` 行。
+- **初始化握手**: 流式模式下 `Query.initialize()` 先发起 `control_request{subtype:"initialize"}`, 同步 Hook 配置, 使 CLI 在后续事件中具备回调 SDK 的上下文与能力声明。
+- **故障回退**: 若回调抛异常, SDK 会返回 `subtype:error` 的 `control_response`, CLI 可依协议退回默认策略 (例如自动拒绝危险工具)。对齐 Claude SDK 的处理方式可降低双方协议分歧, 也是实现 SDK 端双向通信的参考蓝本。
+
+#### 测试与示例
+
+- **测试栈**: 采用 `pytest + pytest-asyncio` 与 `ruff + mypy` 形成与 Anthropic 仓库一致的质量门槛。
+- **示例**: 提供 `examples/quickstart.py`, `examples/mcp_calculator.py` 等, 展示工具注册、流式消费、权限回调落地。
+
+### qwen-agent-sdk-typescript
+
+#### 运行时与分发
+
+- **Node 要求**: Node.js 18+, 与 Anthropic TypeScript SDK 保持一致, 支持 `AbortController`, `EventTarget` 等 API。
+- **包结构**: 主包 `@qwen-agent/sdk` 使用 ESM 默认导出, 通过 `exports` 字段同时暴露 `import` 与 `require` 入口; 类型声明由 `TypeScript 5.x` 编译生成。
+- **构建流水线**: 采用 `tsup` 打包出 `dist/esm` 与 `dist/cjs`, 并生成 `dist/types`。
+
+#### 核心依赖
+
+- `@qwen-code/cli` (peerDependency): 由宿主应用负责安装, SDK 仅负责调度。
+- `zx`/`execa`: 子进程管理与跨平台管道封装。
+- `eventemitter3`: 会话事件派发。
+
+#### API 设计
+
+- **AgentClient**: `createAgentManager(options)` 返回具备 `createSession`, `run`, `forkSession` 能力的管理器, 语义对齐 Anthropic `ClaudeAgent`。
+- **流式 API**: `session.stream(task)` 返回 `AsyncIterable`, 支持 `for await` 迭代。
+- **权限体系**: 暴露 `onPermissionRequest` 回调, 允许应用返回 `allow/deny/ask` 与额外规则。
+- **自定义工具**: 支持依赖 MCP 服务 (`defineTools`), 允许通过 TypeScript 函数注册工具, 与 CLI 会话共享上下文。
+- **设置源控制**: `settingSources` 默认关闭, 需显式声明 `["user","project","local"]` 方可加载对应文件。
+- **子代理**: `agents` 选项允许内联定义多代理拓扑, 结合 `forkSession` 进行会话分支。
+
+#### 技术实现要点
+
+- **子进程编排**: 使用 `execa` 启动 `qwen` CLI, 统一将 stdout 解析为 `AgentStreamChunk`, 并通过 `AbortSignal` 支持取消。
+- **心跳与超时**: 管理器维护 `result/heartbeat` 定时器, 超时自动触发重启与会话恢复。
+- **权限同步**: 将 `onPermissionRequest` 结果转为 JSONL `control_response`, 保证与 Python 绑定行为一致。
+- **调试工具**: 提供 `enableVerboseLogging()` 开关, 输出 CLI 命令、payload、耗时指标。
+- **日志采集**: 默认记录进程级 stdout/stderr 与事件时间轴, 支持注入 `logger`/`stderr` 回调, 并规划接入 OpenTelemetry Trace 以跟踪会话与 Worker 生命周期。
+- **测试矩阵**: 使用 `vitest` + `tsx` 覆盖, 结合 `@qwen-code/cli` mock 校验流式输出与权限回调。
+
+#### 双向控制协议实现参考 (对齐 Claude Agent SDK TS)
+
+- **统一 STDIO 通道**: 复用 CLI `stream-json` 定义的结构, `ProcessTransport` 将 stdout 逐行解码 (`JSON.parse`) 并通过 `EventEmitter` 推送 `control_request`、`result/*`、`chat.completion*` 等事件；所有反向 `control_response` 均通过同一子进程 stdin 写回, 遵循 RFC 中的 JSON Lines 约定。
+- **请求/响应路由**: `createAgentManager()` 在会话级维护 `pendingControl` 映射, `request_id` 作为 key, 保障 `control_request` 并发时的正确配对；若超时则触发 `AbortController.abort()` 并向 CLI 返回 `subtype:"error"`。
+- **权限与 Hook 回调**: `onPermissionRequest`、`onHookEvent` 等回调被包装为 Promise, 统一生成 `control_response` payload (`{"response":{"behavior":"allow"}}` 等); 若上层未注册回调, SDK 直接返回 RFC 规定的默认策略, 避免 CLI 阻塞。
+- **MCP 工具桥接**: `defineTools()` 将 TypeScript 函数组装为 SDK 依赖的 MCP server, CLI 预计通过 `control_request` 中的 `subtype:"mcp_message"` 事件发起 `tools/list`/`tools/call`（对齐 Claude 控制协议设计）, SDK 使用 JSON-RPC 透传至 in-process server 并回写 `mcp_response` 字段, 行为与 Python 版本一致。
+- **初始化握手**: 会话启动时, SDK 主动等待 CLI 首条 `chat.completion` 握手元数据 (`protocol_version`,`capabilities`), 同时根据 RFC 在首个 `control_request{subtype:"initialize"}` 中附带 Hook 配置与工具能力声明, 以便 CLI 构建完整的会话态。
+- **异常降级**: 当反向回调抛出异常或序列化失败时, SDK 会记录 verbose 日志并发送 `control_response{subtype:"error"}`, 提醒 CLI 走安全回退路径 (例如拒绝危险命令), 与 Anthropics TypeScript SDK 的容错策略保持一致。
+
+### 其它语言支持 (TODO)
+
+- **Go/Java**: TODO。
+
+### 2. Qwen-Code Agent SDK (子进程调度层)
+
+> - IPC 封装: (StdinReader, StdoutWriter, 消息路由)
+> - 控制协议: (ControlProtocolService, Hook Registry)
+
+Qwen-Code Agent SDK 直接管理 qwen-code CLI 子进程,负责通信、生命周期与权限控制。
+
+- **IPC 封装**:
+ - 基于 STDIN/STDOUT 的 JSON Lines 协议,输入遵循 `docs/ipc/qwen-chat-request-schema.json`(扩展自 OpenAI `/chat/completions`,包含 `session_id`、`prompt_id`、`tool_call_id` 等会话字段)。
+ - CLI 需提供 `--input-format {text,stream-json}` 与 `--output-format {text,stream-json,stream-chunk-json}` 参数,结构化模式自动禁用 TUI,仅 `text` 模式保留原有人机交互。
+ - 输出逐行写入 OpenAI 风格的 `chat.completion` / `chat.completion.chunk` 对象;首条响应需在 `metadata` 中携带 `protocol_version`、`input_format`、`output_format` 以及 `capabilities`（需显式包含 `chat.completion.chunk` 能力位）等握手信息。
+ - 事件语义需覆盖 `result/heartbeat`、`result/cancel`、`x-qwen-session-event` 与 `control_request/control_response`,并定义对应的错误对象与回退策略。
+ - **当前状态**: qwen-code 仅支持简单的 STDIN 文本读取 (非 JSON Lines)
+ - **需要工作**:
+ - 新增 `StdinReaderService` (~200 行): 解析结构化请求并保持 `/`、`@`、`?` 命令的即时回执。
+ - 新增 `StdoutWriterService` (~150 行): 输出 `chat.completion` / `chat.completion.chunk` JSON Lines,封装错误语义。
+ - 改造 `main()` 入口支持握手元数据、事件分发与流式模式 (~100 行)。
+ - 扩展 CLI 参数解析,落实完整格式选项及 TUI 自动禁用逻辑。
+ - 实现 `result/heartbeat`、`result/cancel`、`x-qwen-session-event`、`control_request/control_response` 的调度骨架。
+
+- **进程管理**:
+ - Worker 进程启动、监控、异常重启
+ - 进程生命周期管理
+ - 资源限制 (CPU/内存/超时)
+ - 关键日志采集 (启动/重启/超时/退出码), 输出到结构化日志或 OpenTelemetry 事件
+
+- **控制协议**:
+ - 工具权限动态授予/撤销
+ - Hook 回调 (pre-commit、post-execute 等)
+ - 会话级配置传递
+ - **当前状态**: qwen-code 有 `ApprovalMode` 权限机制,但不支持程序化回调
+ - **需要工作**:
+ - 新增权限回调接口
+ - 新增 Hooks 系统和事件机制
+ - 在工具执行流程中插入 Hook 点
+
+### 3. Qwen-Code Workers 进程池
+
+热启动的 CLI 进程池,每个 Worker 独立运行。
+
+**环境说明**: Worker 本质是 qwen-code CLI 子进程,其容器/沙箱与工具桥接逻辑均由 CLI 自主管理,SDK 只负责通过 STDIN/STDOUT 进行调度与控制。
+
+**Worker 状态机**:
+
+```
+空闲 (Idle)
+ ↓ [新会话分配]
+占用 (Busy) - 绑定到 session_xxx
+ ↓ [会话结束]
+空闲 (Idle) - 等待新会话复用
+```
+
+**关键特性**:
+
+- **独占机制**:一个 Worker 一次只能服务一个会话,保证会话隔离。
+- **会话绑定**:Worker 与会话 ID 绑定,期间不接受其他任务。
+- **复用机制**:
+ - 会话结束后 Worker **不会自动销毁**
+ - Worker 返回空闲池,等待新会话分配
+ - 新会话复用现有进程,创建新的会话上下文
+ - 大幅减少冷启动时间,提高响应速度
+
+**Worker 复用流程**:
+
+```
+1. 会话 A 结束 → Worker #1 状态变为 [空闲]
+2. 新会话 B 到达 → 协调器分配 Worker #1
+3. Worker #1 状态变为 [占用 - session_B]
+4. Worker #1 在同一进程内创建新会话上下文
+5. 会话 B 执行完毕 → Worker #1 再次变为 [空闲]
+```
+
+**进程池配置**:
+
+- `min_workers`:最小保活 Worker 数量
+- `max_workers`:最大 Worker 数量上限
+- `idle_timeout`:空闲 Worker 超时回收时间 (默认 30 分钟)
+- `max_concurrent_sessions`:单 Worker 生命周期内最大服务会话数
+
+## Worker 复用机制详解
+
+### 为什么需要 Worker 复用?
+
+**问题**:每次新会话启动全新进程会导致:
+
+- 进程冷启动耗时 (3-5 秒)
+- 模型加载耗时 (如果涉及本地模型)
+- 资源开销大 (频繁创建/销毁进程)
+
+**方案**:Worker 进程复用
+
+- 进程保持运行,会话结束后只清理会话上下文
+- 新会话到达时直接在现有进程中创建新会话
+- 响应速度提升 **10-20 倍**
+
+### 复用安全性保障
+
+1. **会话隔离**:
+ - 每个会话独立的上下文空间
+ - 会话结束时清理所有会话变量和状态
+ - 下一个会话无法访问上一个会话的数据
+
+2. **资源清理**:
+ - 临时文件自动清理
+ - 环境变量重置
+ - 打开的文件句柄关闭
+
+3. **健康检查**:
+ - 定期检测 Worker 内存泄漏
+ - 检测僵尸进程或卡死状态
+ - 异常 Worker 自动重启
+
+### 复用策略配置
+
+```yaml
+worker_pool:
+ # 最小保活 Worker 数
+ min_workers: 5
+
+ # 最大 Worker 数
+ max_workers: 50
+
+ # 空闲 Worker 超时回收 (秒)
+ idle_timeout: 1800 # 30 分钟
+
+ # 单个 Worker 最大服务会话数 (防止内存泄漏)
+ max_sessions_per_worker: 100
+
+ # Worker 健康检查间隔 (秒)
+ health_check_interval: 60
+```
+
+### 日志与可观测要求
+
+- **会话日志**: Worker 在会话开始、结束及异常重启时输出结构化 JSON 日志 (session_id、prompt_id、耗时、命令摘要), 支持通过 SDK 的 `logger`/`stderr` 回调或集中式日志系统采集。
+- **指标采集**: SDK 侧规划基于 OpenTelemetry 导出 Worker 池指标 (活跃/空闲数量、排队时长、重启次数、失败率), 与 CLI 层指标互补, 便于平台层聚合。
+- **链路追踪**: 为每个会话生成 Trace Span, 在 SDK → CLI → 工具调用之间传播, 方便定位跨组件延迟与失败点。
+
+## 集成模式
+
+### 宿主进程依赖 SDK
+
+- **适用场景**: IDE 插件、企业内部工具、CLI 扩展等需要最小化依赖的场合。
+- **关键特性**:
+ - SDK 直接在宿主进程内启动与管理 Worker 池
+ - 通过 IPC JSONL 协议与 qwen-code CLI 通信
+ - 可同步或流式获取会话输出
+
+**快速上手示例**:
+
+```python
+from qwen_agent_sdk import QwenClient
+
+with QwenClient(binary_path="qwen", model="qwen3-coder-plus") as client:
+ result = client.chat(
+ task="扫描并修复 main.py 中的潜在 bug",
+ workspace="/repos/demo"
+ )
+ print(result.summary)
+```

+# RFC: Qwen-Code CLI 结构化输入输出规范（整理版）
+
+## 概览
+
+| 字段 | 详情 |
+| --- | --- |
+| 状态 | Draft |
+| 更新时间 | 2025-10-13 |
+| 作者 | x22x22 |
+| 追踪 | |
+| 范围 | CLI 层 `--input-format/--output-format` 结构化协议、事件语义、错误规范与落地计划 |
+
+- 目标是为第三方系统与多语言 Agent SDK 提供稳定、可编程的 IPC Stream JSON 能力。
+- 协议保持与 TUI 相同的行为，补齐 JSON Lines 输出、对称输入以及控制通道，回应社区关于 `--input-format/--output-format json/stream-json` 的诉求。
+- 文档聚焦 CLI 侧能力，不涵盖 SDK 内部设计。
+
+## 背景与场景
+
+### Issue 795 概述
+- 社区在 issue [#795](https://github.com/QwenLM/qwen-code/issues/795) 中请求为 CLI 增加 `--input-format/--output-format json/stream-json`，希望参考 Claude Code 的实现，提供可被程序稳定消费的结构化 IO。
+- RFC 旨在扩展 CLI，使其在保持 TUI 兼容的同时，为 SDK 与第三方后端提供对称的 JSON 协议与消息语义。
+
+### 集成方场景
+- **任务级串行处理**：SDK 逐条发送 prompt，同时在多个阶段接收 CLI 返回的数据并二次处理后再展示给最终用户。
+- **任务级流式直传**：SDK 逐条发送 prompt，CLI 的流式响应被直接转发给用户，保持实时可见性。
+- **指令提示与快捷符号**：第三方输入框中的 `/`、`@`、`?` 等触发行为需要与 TUI 完全一致，确保不同前端体验统一。
+- **前端终端模拟**：利用 xterm.js 等库复刻终端交互，输入区域与终端输出分离，但仍需消费 CLI 的完整终端语义。
+
+### 集成方式
+- 第三方程序依赖后续提供的多语言 `qwen-code-agent-sdk`。
+- SDK 通过子进程方式启动 `qwen code`，并以 STDIN/STDOUT 建立双向 IPC。
+- SDK 负责读取 CLI 的结构化输出，并完成错误处理与状态管理。
+- 第三方应用消费 SDK 的结果，在自身 UI 或后端逻辑中呈现。
+
+### 现状痛点
+- CLI 仅面向人工交互的纯文本 STDOUT，输出语义不稳定，难以被自动化消费。
+- 缺乏对称的结构化输入协议，无法驱动高级自动化与工具调度流程。
+
+## 目标与范围
+
+| 类型 | 内容 |
+| --- | --- |
+| 设计目标 | 可配置输出格式、JSON Lines 流式协议、对称结构化输入、通用 schema、面向 SDK 友好化 |
+| 非目标 | 描述 SDK 具体实现（另见 Agent 框架文档） |
+| 核心痛点 | 仅有人机交互 STDOUT、缺少结构化输入、无法驱动自动化流程 |
+| 场景示例 | SDK 分批发送 prompt 并处理多段响应；流式直传用户；`/`,`@`,`?` 指令与 TUI 对齐；xterm.js 前端分离输入与终端 |
+
+## 接口总览
+
+| 类别 | 关键项 | 说明 |
+| --- | --- | --- |
+| CLI 参数 | `--input-format`、`--output-format` | 取值 `text` / `stream-json` / `stream-chunk-json`，结构化模式自动禁用 TUI |
+| 输出事件 | `chat.completion*`、`result/*`、`control_request` | 全部以 JSON Lines 逐行写入 STDOUT |
+| 输入事件 | `*request`、`control_response`、Qwen Chat Request | JSON 行写入 STDIN，对称驱动 CLI 行为 |
+| 通道语义 | 结果事件、请求事件、控制通道 | 明确回执要求，防止 CLI 阻塞 |
+| 协议扩展 | 握手元数据、版本协商、错误语义 | 与 OpenAI `/chat/completions` 保持兼容扩展 |
+
+- 通信仍使用标准输入输出，未引入额外套接字。
+- `text` 模式保留原行为，结构化模式提供稳定 schema 与可观测字段。
+
+## 输出格式语义
+
+| 格式 | 适用场景 | 行为概要 | 兼容性 |
+| --- | --- | --- | --- |
+| `text` | 人机交互兼容模式 | 输出原有 TUI 文本 | 默认模式，后续标记为手动使用 |
+| `stream-json` | 消息级 JSONL | 每行 `chat.completion`，含初始化回执、助手回复、工具调用、收尾摘要 | 对齐 OpenAI `/chat/completions` |
+| `stream-chunk-json` | 增量 chunk JSONL | 每行 `chat.completion.chunk`，`choices[].delta` 承载 token/块增量 | 对齐 OpenAI 流式响应，覆盖完整会话 ID |
+
+### 消费策略
+
+- **消息级 JSONL（`stream-json`）**：适合第三方后端或 CLI 包装器按阶段消费结果，与现有 JSONL 管线兼容，是默认结构化模式。
+- **增量 chunk（`stream-chunk-json`）**：面向 IDE/UI“边生成边展示”的实时场景，SDK 需监听 `chat.completion.chunk` 并在收到最终 `finish_reason` 时收尾。
+- **终端语义一致性**：无论 CLI 在文本模式还是结构化模式，`stream-json` 与 `stream-chunk-json` 都必须完整覆盖 TUI 向标准输出写入的全部语义（文本、ANSI/Vt100 控制、工具提示、退出码等），并通过 `choices[].message.content` / `choices[].delta.content` 与 `choices[].delta.annotations`（如 `{"type":"x-qwen-ansi","value":"\u001b[32m"}`）编码，便于 xterm.js 等终端完全还原效果。
+
+### `stream-json` 示例

+```
+
+### `stream-chunk-json` 行为要点
+
+- 首行发送 `{"object":"chat.completion.chunk","choices":[{"delta":{"role":"assistant"}}]}` 声明角色。
+- 按需输出文本 token、工具调用增量、`tool_calls` 更新。
+- 最后一行包含 `{"choices":[{"delta":{},"finish_reason":"stop"}]}`，并在 `usage` 或 `metadata` 中附带总结。
+- 可选 `annotations`、`spans` 字段详述终端样式（见下节）。
+
+## 事件载荷与注解
+
+`packages/cli/src/nonInteractiveCli.ts` 与 `packages/cli/src/ui/utils/ConsolePatcher.ts` 共同决定了文本模式输出的来源：模型内容通过 `GeminiEventType.Content` 写入 `stdout`，工具执行状态与日志由 `ConsolePatcher` 打印至 `stderr`，工具结果结构体 (`ToolResultDisplay` 等) 则在 `packages/cli/src/ui/hooks/useReactToolScheduler.ts` 中驱动 UI 渲染。为保证 `stream-json` / `stream-chunk-json` 能完整覆盖这些语义，整理版沿用原 RFC 在 OpenAI `annotations` 字段上的扩展约定：
+
+| 类型 | 主要字段 | 用途 |
+| --- | --- | --- |
+| `chat.completion.chunk` 注解 | `annotations`、`spans` | 复刻终端风格、ANSI 控制、来源标记 |
+| `x-qwen-terminal` | `channel`、`source`、`console_level`、`ansi` | 输出终端流（stdout/stderr/console/system） |
+| `x-qwen-tool-display` | `tool_call_id`、`status`、`result_display` | 呈现工具 diff、字符串、TODO、计划摘要、任务执行等 |
+| `x-qwen-thought` | `subject`、`description` | 展示思考中提示（GeminiEventType.Thought） |
+| `x-qwen-session-event` | `event`、`message`、`metrics` | 会话级提示，如压缩、取消、token 限制 |
+
+### 终端注解结构
+
+```json
+{
+ "type": "x-qwen-terminal",
+ "channel": "stdout",
+ "source": "assistant",
+ "spans": [
+ {"start": 0, "end": 24, "style": {"theme_token": "AccentGreen"}}
+ ],
+ "ansi": [
+ {"offset": 0, "code": "\u001b[32m"},
+ {"offset": 24, "code": "\u001b[0m"}
+ ],
+ "console_level": "info",
+ "exit_code": null,
+ "prompt_id": "session-123########7"
+}
+```
+
+- `channel`: `stdout` / `stderr`，控制台日志通过 `ConsolePatcher` 注入 `stderr` 与 `console_level`。
+- `source`: `assistant`、`tool`、`console`、`system`；便于前端分层展示。
+- `spans.style.theme_token`: 复用 CLI 主题 (`AccentGreen`、`DiffAdded` 等)。
+- `ansi`: 原始 ANSI 序列位置，方便前端重放。
+- `console_level`: 当 `source=console` 时取 `log` / `warn` / `error` / `info` / `debug`，与 `ConsolePatcher` 输出保持一致。
+- `exit_code`: 当 `source=system` 且流程结束时给出退出码。
+- `prompt_id`: 关联到具体回合。
+
+### 工具结果展示
+
+```json
+{
+ "type": "x-qwen-tool-display",
+ "tool_call_id": "call_tool-1",
+ "session_id": "session-123",
+ "status": "executing",
+ "result_display": {
+ "kind": "file_diff",
+ "file_name": "src/main.py",
+ "diff": "--- a/src/main.py\n+++ b/src/main.py\n@@ -1 +1 @@\n-print('Hi')\n+print('Hello')",
+ "original": "print('Hi')\n",
+ "modified": "print('Hello')\n",
+ "stat": {
+ "ai_added_lines": 1,
+ "ai_removed_lines": 1,
+ "user_added_lines": 0,
+ "user_removed_lines": 0
+ }
+ },
+ "confirmation": null,
+ "pending": false,
+ "timestamp": 1739430005
+}
+```
+
+- `status` 取自 `ToolCallStatus`（`Pending`、`Executing`、`Success`、`Error`、`Canceled`、`Confirming`）。
+- `tool_call_id` 复用 OpenAI schema 字段名，结合 `session_id` 可唯一定位调用；在测试或非会话模式下也可单独使用。
+- `result_display` 支持 `string`、`file_diff`、`todo_list`、`plan_summary`、`task_execution` 等 union。
+- `confirmation` 序列化 `ToolCallConfirmationDetails` 中的 diff、命令、计划等信息，便于第三方弹窗确认。
+- `pending=true` 表示调用仍在验证/排队阶段，尚未交给执行器，与 `ToolCallStatus.Pending` 等价。
+- `timestamp` 用于排序，与 `useReactToolScheduler` 记录一致。
+
+### 思考与会话事件
+
+```json
+{
+ "type": "x-qwen-thought",
+ "subject": "Analyzing repo",
+ "description": "Listing tsconfig patterns..."
+}
+```
+
+```json
+{
+ "type": "x-qwen-session-event",
+ "event": "MAX_TOKENS",
+ "message": "Response truncated due to token limits.",
+ "metrics": {
+ "original_tokens": 12000,
+ "compressed_tokens": 8000
+ }
+}
+```
+
+- `event` 取值来自 `GeminiEventType`，包括 `Finished`、`ChatCompressed`、`MaxSessionTurns`、`USER_CANCELLED` 等。
+- `metrics` 可选地提供压缩前后 token 数等统计。
+
+## 输入格式（Qwen 会话协议）
+
+| 模式 | 行为 | 说明 |
+| --- | --- | --- |
+| `text` | 保留原始 TUI 文本输入 | 解析自然语言或命令行文本 |
+| `stream-json` / `stream-chunk-json` | 采用 Qwen Chat Request | 每行 JSON 描述一次增量输入 |
+
+### Qwen Chat Request 模式
+
+```jsonc
+{
+ "session_id": "session-123",
+ "prompt_id": "session-123########7",
+ "model": "qwen-coder",
+ "input": {
+ "origin": "user",
+ "parts": [
+ {"type": "text", "text": "请修复 @main.py 的 bug"}
+ ],
+ "command": null
+ },
+ "options": {
+ "temperature": 0.2,
+ "tool_overrides": ["EditTool"]
+ }
+}
+```
+
+- `session_id`：会话主键（`config.getSessionId()`），传入 `"_new"` 可创建新会话。
+- `prompt_id`：区分回合；默认格式 `########`，须在工具续写时复用。
+- `input.origin`：`user` / `tool_response` / `system`，决定会话续写逻辑。
+- `input.parts`：兼容 `@google/genai` PartListUnion，允许 `text`、`function_response`、`file_data` 等；当 `origin="user"` 时，CLI 会将所有 `text` part 顺序拼接并复用 `prepareQueryForGemini` 的语义处理。
+- `options`：单次请求参数覆写（模型、采样、工具白名单）。
+- 扩展字段：
+ - `tool_call_id`：`origin=tool_response` 时必填，用于匹配输出事件。
+ - `continuation`: 布尔值，等价 `submitQuery(...,{isContinuation:true})`；缺省时 CLI 会根据 `origin` 与命令上下文判断是否续写。
+ - `tool_request`: 镜像 `ToolCallRequestInfo`，支撑并发工具与子代理。
+
+### 会话控制
+
+- 第三方可调用 CLI 提供的“创建会话”命令或复用已有 ID；当 `session_id` 缺失或指定为 `"_new"` 时，CLI 会在首个 `chat.completion` 中返回实际 ID。
+- `prompt_id` 与 `tool_call_id` 共同确保并发流程隔离，需在工具回传与续写时保持一致；默认格式 `########`，也可自定义但必须唯一。
+- 使用 `input.origin="system"` 并在 `parts` 中发送 `{"type":"instruction","text":"/clear"}` 等指令，可触发与 TUI 相同的 slash 命令逻辑。
+- 当 `origin="tool_response"` 时，必须提供 `tool_call_id` 以关联输出事件；CLI 会将结果写入对应回合并继续调度。
+
+### 命令与 `@` 引用
+
+| 模式 | 触发方式 | 行为 |
+| --- | --- | --- |
+| 隐式解析 | `origin="user"` + 文本以 `/`/`?`/`@` 开头 | CLI 自动走 slash/at 流程，调用 `handleAtCommand` 等逻辑 |
+| 显式声明 | `input.command` 描述命令 | 推荐给第三方，避免字符串解析歧义 |
+
+- `command.kind`: `slash` / `at`，与 TUI 命令分类一致。
+- `command.path`: 对于 slash 命令是层级数组（等价 `commandPath`），`at` 模式可省略。
+- `command.args`: 剩余参数字符串，CLI 会按原逻辑解析。
+- `input.command.references` 支持在 `kind="at"` 时直接提供已解析的引用列表，例如 `{ "original":"@src/main.ts","resolved":"src/main.ts" }`，CLI 会基于显式路径读取文件。
+- 若未传入 `references`，CLI 将回退到 `handleAtCommand` 与 `useAtCompletion` 的自动解析逻辑，以保持与 TUI 相同的容错能力。
+
+#### 显式 slash 命令示例
+
+```jsonc
+{
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": ""}],
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ }
+ }
+}
+```
+
+#### 显式 `@` 引用示例
+
+```jsonc
+{
+ "session_id": "session-123",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": "请审阅 @src/main.py"}],
+ "command": {
+ "kind": "at",
+ "references": [
+ {"original": "@src/main.py", "resolved": "src/main.py"}
+ ]
+ }
+ }
+}
+```
+
+### SDK 侧命令协作
+
+| `command.result.type` | 说明 | SDK 建议动作 |
+| --- | --- | --- |
+| `handled` | 命令已在 CLI 内部完成 | 无需额外处理 |
+| `message` | 返回信息或错误 | 直接在 UI 显示通知 |
+| `dialog` (`auth`/`theme`/`editor`/`privacy`/`settings`/`model`/`subagent_create`/`subagent_list`/`help`) | 需要弹窗或页面跳转 | 在第三方界面呈现对应对话框 |
+| `tool` | 触发工具调用 | 将 `tool_request` 或命令参数转为工具请求并继续监听结果 |
+| `submit_prompt` | 立即发送 PartListUnion 至模型 | 将 `content` 作为下一条输入并设置 `continuation=true` |
+| `load_history` | 重置或加载指定会话历史 | 触发历史刷新或重新加载 |
+| `quit` / `quit_confirmation` | 退出流程或等待用户确认 | 控制宿主应用生命周期并回传确认结果 |
+| `confirm_shell_commands` | 待确认 shell 命令 | 弹窗确认，批准后携带 `approvedCommands`/`confirmationOutcome` 再次调用 |
+| `confirm_action` | 需要确认提示 | 提供确认按钮并返回结构化结果 |
+
+- SDK 应暴露统一命令执行 API，将用户输入映射为上述 `command` 结构，并根据 `result` 类型驱动本地 UI 或后续请求。
+- CLI 会使用显式 `references` 读取文件；若缺失则自动回退到 `handleAtCommand` 的解析流程，保证行为与 TUI 完全一致。
+- 命令触发后续模型调用时，CLI 会继续输出 `assistant`、`tool_call` 与 `result/*` 事件，顺序保持与 TUI 相同，使第三方可以通过纯文本输入与 JSON 输出复现完整交互。
+
+### STDIN 命令回执
+
+- 当 `--input-format=stream-json` 时，CLI 必须对 `/`、`?`、`@` 等命令保持即时反馈，解析逻辑沿用 `useSlashCommandProcessor` 与 `handleAtCommand`。
+- 命令解析完成后，CLI 将向 STDOUT 写出结构化响应：
+
+```jsonc
+{
+ "type": "result/command",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ },
+ "result": {
+ "type": "message",
+ "level": "info",
+ "content": "当前会话共有 3 条历史记录"
+ }
+}
+```
+
+- `result` 字段遵循上表所列 `command.result.type` 枚举，便于 SDK 在收到 `stream-json`/`stream-chunk-json` 时立即驱动 UI。
+- 若命令触发进一步的模型交互（如 `/submit`、`@file` 展开），CLI 会在同一会话中继续串联对应事件并保持字段一致。
+
+## 实时提示、心跳与中断
+
+| 能力 | 请求 | 响应 | 说明 |
+| --- | --- | --- | --- |
+| 命令提示 | `command_hint_request` | `result/command_hint` | 字符触发提示；`trigger` 支持 `slash`、`at`；`status` 可为 `ok` / `loading` / `error` |
+| 心跳 | `heartbeat_request` | `result/heartbeat` | 定期保活；CLI 可主动推送同结构事件 |
+| 中断/取消 | `control/cancel` | `result/cancel` + `control_response` | 模拟 ESC；`reason` 当前固定 `escape` |
+
+### 提示请求示例（`/c`）
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/c",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### 提示响应示例
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {"label": "chat", "value": "chat", "description": "Manage conversation history."},
+ {"label": "clear", "value": "clear", "description": "clear the screen and conversation history"},
+ {"label": "compress", "value": "compress", "description": "Compresses the context by replacing it with a summary."},
+ {"label": "copy", "value": "copy", "description": "Copy the last result or code snippet to clipboard"},
+ {"label": "corgi", "value": "corgi", "description": "Toggles corgi mode."}
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+}
+```
+
+### 提示请求示例（`@src/co`）
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "text": "@src/co",
+ "cursor": 7,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### 提示响应示例（`@src/co`）
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "status": "ok",
+ "suggestions": [
+ {"label": "src/components/", "value": "src/components/"},
+ {"label": "src/components/Button.tsx", "value": "src/components/Button.tsx"},
+ {"label": "src/components/Button with spaces.tsx", "value": "src/components/Button\\ with\\ spaces.tsx"}
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+}
+```
+
+### 提示请求示例（`/?`）
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/?",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### 提示响应示例（`/?`）
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {
+ "label": "help",
+ "value": "help",
+ "description": "for help on Qwen Code",
+ "matchedIndex": 0
+ }
+ ],
+ "metadata": {
+ "is_perfect_match": true
+ }
+}
+```
+
+- `suggestions` 结构复用 TUI `Suggestion`，`status="loading"` 表示 CLI 正在准备数据，`error` 时附带 `message`。
+- CLI 内部复用 `useSlashCompletion`、`useAtCompletion` 生成提示；这些请求不会写入会话历史，`prompt_id` 可使用 `_preview` 后缀并在响应中原样返回。
+- 支持连续触发：输入或光标变化时可重复发送 `command_hint_request`，CLI 负责节流并返回最新结果；取消提示时发送 `{"type":"command_hint_cancel",...}`。
+
+### 心跳请求与响应
+
+```jsonc
+{"type":"heartbeat_request","session_id":"session-123"}
+{"type":"result/heartbeat","session_id":"session-123","status":"ok","ts":1739430123}
+```
+
+- 第三方可配置超时（如 10 秒）判断 CLI 是否挂起并执行重启。
+- CLI 会按相同结构回复 `result/heartbeat`，也可在后台主动推送保活事件。
+- `@third-party/anthropics/claude-agent-sdk-python` 目前缺少心跳实现；P1.1 落地时需定义默认间隔、超时策略，并允许 SDK 自定义心跳频率。
+
+### 中断示例
+
+```jsonc
+{
+ "type": "control/cancel",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "reason": "escape"
+}
+```
+
+- CLI 必须调用 `cancelOngoingRequest`，中止 `AbortController`，补齐历史项并发出 `result/cancel`。
+- 若当前无可取消请求，CLI 应返回 `{"type":"result/cancel","status":"noop"}` 并说明原因。
+- 当底层流返回 `GeminiEventType.UserCancelled` 事件时，CLI 需追加 `{"type":"x-qwen-session-event","event":"USER_CANCELLED","message":"User cancelled the request."}` 提示会话被中断。
+- 双击 ESC 清空输入属于客户端自身逻辑，结构化模式的集成方可在本地复用该交互，无需额外向 CLI 发送消息。
+
+## 事件分类与通道
+
+| 类别 | 方向 | 代表事件 | 回执要求 | 作用 |
+| --- | --- | --- | --- | --- |
+| 结果事件 | CLI → STDOUT | `result/command`、`result/command_hint`、`result/heartbeat`、`result/cancel`、`x-qwen-session-event` | 无需回执 | 发布命令输出、状态提示、心跳结果 |
+| 请求事件 | SDK/第三方 → STDIN | `command_hint_request`、`heartbeat_request`、`control/cancel` | CLI 返回对应 `result/*` | 触发即时行为或控制 |
+| 控制通道 | CLI ↔ STDIN/STDOUT | `control_request` / `control_response` | 必须匹配 `request_id` | 权限审批、Hook 回调、MCP 调用 |
+
+按语义还可归纳三类事件机制：
+
+1. **结果事件 (`result/*`)**
+ - CLI → STDOUT 的单向通告，承载命令输出、提示建议、心跳反馈、会话状态更新等信息。
+ - 不要求第三方回执，可直接用于 UI 展示与日志记录。
+2. **请求事件 (`*request`)**
+ - 第三方 → STDIN 的即时指令，例如 `command_hint_request`、`heartbeat_request`、`control/cancel`。
+ - CLI 会以对应的 `result/*` 响应，确保提示、保活与取消流程与 TUI 一致。
+3. **控制通道事件 (`control_request` / `control_response`)**
+ - CLI 输出 `control_request`、第三方写回 `control_response`，用于工具授权、Hook 回调、MCP 调用等需要回执的场景。
+ - 每条请求含唯一 `request_id`，必须在合理超时内返回结果，该类事件不写入会话历史而走控制层旁路。
+
+- 所有事件通过统一 JSON Lines 协议传输，集成方应按 `type`/`subtype` 路由；对控制通道需实现超时与错误回退策略，以避免 CLI 阻塞并保持与 TUI 行为一致。
+
+## 控制请求与响应
+
+| 字段 | 说明 |
+| --- | --- |
+| `type` | 固定 `control_request` 或 `control_response` |
+| `request_id` | 唯一标识，请求与响应配对 |
+| `subtype` | `can_use_tool`、`hook_callback`、`mcp_message` 等 |
+| `payload` / `response` | 携带事件明细或回执内容 |
+
+- `control_request` 示例：
+
+```jsonc
+{
+ "type": "control_request",
+ "request_id": "req-1",
+ "subtype": "can_use_tool",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "tool": {
+ "name": "edit_file",
+ "arguments": {"path": "main.py", "patch": "..."}
+ },
+ "metadata": {
+ "reason": "apply_diff"
+ }
+}
+```
+
+- 对应 `control_response`：
+
+```jsonc
+{
+ "type": "control_response",
+ "request_id": "req-1",
+ "response": {
+ "subtype": "success",
+ "result": {
+ "behavior": "approve",
+ "message": "允许执行"
+ }
+ }
+}
+```
+
+- 代码现状：当前 CLI 仅支持单向输出，TUI 内的确认/对话框逻辑在进程内处理，缺少 Claude Code 样式的 `control_request`/`control_response` hook。
+- 设计需求：当 CLI 需要外部确认或回执时输出 `control_request`，第三方在 STDIN 写入匹配的 `control_response` 完成授权或补充信息，覆盖工具审批、Hook 回调、MCP JSON-RPC 等场景。
+- 场景覆盖：`/confirm_shell_commands`、`confirm_action`、`quit_confirmation`、工具权限审批、子代理调度，以及未来的弹窗、表单、身份验证流程。
+- 回退策略：若控制通道未启用，CLI 应显式拒绝危险操作或提示“结构化模式下不可用”，并通过 `result/command` 返回错误，避免静默失败。
+- 后续工作：1）在 RFC 中追加 `control_request`/`control_response` JSON Schema；2）在 CLI 内抽象统一控制消息分发层，让 TUI 与 CLI 复用逻辑；3）在 SDK 中实现监听与响应，向上层 UI 暴露钩子。
+- 若回调异常，SDK 需返回 `{"subtype":"error","error":{"message":"...", "retryable":false}}`，CLI 按协议走安全回退（自动拒绝或提示失败）。
+- MCP 集成：`subtype:"mcp_message"` 承载 JSON-RPC (`tools/list`、`tools/call` 等)，SDK 将结果封装为 `control_response` 内的 `mcp_response`。
+
+## 版本协商与错误语义
+
+| 项目 | 说明 |
+| --- | --- |
+| 协议版本 | 首个 `chat.completion` 的 `metadata` / `system_fingerprint` 携带 `protocol_version`、`input_format`、`output_format`、`capabilities` |
+| 版本不匹配 | 若 SDK 请求超出能力，CLI 返回 `finish_reason="error"`，在 `metadata.error` 中标记 `unsupported_protocol` 并以非零退出码终止 |
+| 致命错误 | 输出 OpenAI 风格错误对象并退出 |
+| 可恢复错误 | 通过 `chat.completion` 返回错误信息，`finish_reason` 为 `stop/tool_calls`，进程保持健康 |
+| 控制协议错误 | 在 `metadata.control_errors` 中附带详情，供 SDK 决定重试或终止 |
+
+致命错误示例：
+
+```json
+{
+ "error": {
+ "message": "invalid tool input",
+ "type": "invalid_request_error",
+ "param": "tools[0].function.arguments",
+ "code": "QWEN_INVALID_TOOL_ARGS"
+ }
+}
+```
+
+## 安全与资源控制
+
+| 领域 | 策略 |
+| --- | --- |
+| 权限 | 结构化模式仍遵循 CLI 现有 Approval / 工具白名单；无回执时默认拒绝高风险操作 |
+| 审计 | 控制通道允许 SDK 在敏感动作前进行审计；未启用时需在 `result/command` 明确提示 |
+| 保活 | `heartbeat` 事件可触发进程回收、避免资源泄漏 |
+
+## 日志分层与可观测
+
+| 组件 | 要点 |
+| --- | --- |
+| ConsolePatcher | 拦截 `console.*`，在 `x-qwen-terminal` 中记录 `channel="stderr"`、`console_level` |
+| log_scope 扩展 | 建议在结构化模式下为注解附加 `log_scope`（`system`、`tool`、`debug`），与 `ConfigLogger` 级别对齐 |
+| 工具日志 | 通过 `ToolResultDisplay` 输出，可在 `result_display` 中附带 `log_scope` 便于过滤 |
+| OTel 规划 | SDK/CLI 分别接入 OpenTelemetry，串联 Trace/Span |
+
+- 建议第三方记录完整消息序列到审计日志，便于重放。
+
+## 调试示例
+
+```bash
+echo '{"model":"qwen-coder","messages":[{"role":"user","content":"你好"}]}' \
+ | qwen --input-format stream-json --output-format stream-json
+
+echo '{"model":"qwen-coder","messages":[{"role":"user","content":"逐字输出问候"}]}' \
+ | qwen --input-format stream-json --output-format stream-chunk-json
+```
+
+- 命令可用于快速验证输出格式与事件流。

+# RFC: Qwen-Code CLI Structured Input/Output Specification (Clean Version)
+
+## Overview
+
+| Field | Details |
+| --- | --- |
+| Status | Draft |
+| Last Updated | 2025-10-13 |
+| Author | x22x22 |
+| Tracking | |
+| Scope | CLI-level `--input-format/--output-format` structured protocol, event semantics, error specification, and rollout plan |
+
+- Aims to provide third-party systems and multi-language Agent SDKs with stable, programmable IPC Stream JSON capabilities.
+- Keeps protocol behavior aligned with the TUI, adds JSON Lines output, symmetric input, and control channels to address community requests for `--input-format/--output-format json/stream-json`.
+- The document focuses on CLI capabilities and does not cover SDK internals.
+
+## Background and Scenarios
+
+### Issue 795 Overview
+- Community issue [#795](https://github.com/QwenLM/qwen-code/issues/795) requests `--input-format/--output-format json/stream-json`, aiming to mirror the Claude Code implementation so downstream programs can reliably consume structured IO.
+- This RFC expands the CLI while staying compatible with existing TUI behavior, giving SDKs and backends symmetric JSON protocols and message semantics.
+
+### Integration Scenarios
+- **Task-level staged handling**: SDK submits prompts one by one, receives multiple partial results, post-processes them, and finally presents them to end users.
+- **Task-level streaming**: SDK submits prompts and streams the CLI’s response directly to users for real-time visibility.
+- **Instruction shortcuts**: Third-party input boxes must support `/`, `@`, and `?` triggers with behavior identical to the TUI to guarantee a consistent UX.
+- **Terminal simulation**: Frontends such as xterm.js mimic terminal output while separating the input field from the display, yet still need full terminal semantics from the CLI.
+
+### Integration Approach
+- Third parties will rely on forthcoming multi-language `qwen-code-agent-sdk` packages.
+- The SDK spawns `qwen code` as a subprocess and uses STDIN/STDOUT for bidirectional IPC.
+- SDKs read the CLI’s structured output and handle errors and state transitions.
+- Upper-layer applications consume the SDK’s results and render them in their own UI or services.
+
+### Current Pain Points
+- The CLI currently emits human-oriented text, making structured consumption brittle.
+- There is no symmetric structured input protocol, preventing higher-level automation and tool orchestration.
+
+## Goals and Scope
+
+| Type | Content |
+| --- | --- |
+| Design Goals | Configurable output formats, JSON Lines streaming protocol, symmetric structured input, common schemas, SDK-friendly |
+| Non-Goals | Describing concrete SDK implementations (see the Agent Framework document) |
+| Core Pain Points | Only human-readable STDOUT, lack of structured input, cannot drive automation |
+| Scenario Examples | SDK sending prompts in batches and handling multi-segment responses; streaming directly to users; `/`, `@`, `?` commands matching TUI behavior; xterm.js frontends splitting input from terminal display |
+
+## Interface Overview
+
+| Category | Key Items | Description |
+| --- | --- | --- |
+| CLI Parameters | `--input-format`, `--output-format` | Values: `text` / `stream-json` / `stream-chunk-json`; structured modes automatically disable the TUI |
+| Output Events | `chat.completion*`, `result/*`, `control_request` | Written to STDOUT line by line as JSON Lines |
+| Input Events | `*request`, `control_response`, Qwen Chat Request | Written to STDIN as JSON Lines to drive CLI behavior symmetrically |
+| Channel Semantics | Result events, request events, control channel | Clarify acknowledgment requirements to prevent CLI blocking |
+| Protocol Extensions | Handshake metadata, version negotiation, error semantics | Remain compatible extensions to OpenAI `/chat/completions` |
+
+- Communication still uses standard input and output; no extra sockets are introduced.
+- `text` mode preserves the original behavior, while structured modes provide stable schemas and observability fields.
+
+## Output Format Semantics
+
+| Format | Applicable Scenarios | Behavior Summary | Compatibility |
+| --- | --- | --- | --- |
+| `text` | Human-interactive compatibility mode | Outputs the original TUI text | Default mode, to be marked for manual use later |
+| `stream-json` | Message-level JSONL | Each line is a `chat.completion`, including initialization receipts, assistant replies, tool invocations, and closing summaries | Aligns with OpenAI `/chat/completions` |
+| `stream-chunk-json` | Incremental chunk JSONL | Each line is a `chat.completion.chunk`, with `choices[].delta` carrying token/block increments | Aligns with OpenAI streaming responses, with full session IDs |
+
+### Consumption Strategy
+
+- **Message-level JSONL (`stream-json`)**: Suited to third-party backends or CLI wrappers that process results in stages; compatible with existing JSONL pipelines and considered the default structured mode.
+- **Incremental chunks (`stream-chunk-json`)**: Targets IDE/UI scenarios that need “display as it streams”; SDKs should watch for `chat.completion.chunk` events and finalize once the terminal `finish_reason` arrives.
+- **Terminal semantics parity**: Regardless of whether the CLI runs in text or structured mode, `stream-json` / `stream-chunk-json` must cover every semantic emitted by the TUI (text, ANSI/Vt100 control codes, tool hints, exit codes, etc.) using `choices[].message.content` / `choices[].delta.content` plus `choices[].delta.annotations` (e.g. `{"type":"x-qwen-ansi","value":"\u001b[32m"}`) so frontends like xterm.js can faithfully reproduce the terminal experience.
+
+### `stream-json` Example
+
+```json
+{"object":"chat.completion","id":"chatcmpl-session-123","created":1739430000,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","content":"Analyzing...","tool_calls":null},"finish_reason":"stop"}],"usage":{"prompt_tokens":1200,"completion_tokens":80,"total_tokens":1280}}
+{"object":"chat.completion","id":"chatcmpl-session-123","created":1739430002,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","tool_calls":[{"id":"tool-1","type":"function","function":{"name":"edit_file","arguments":"..."}}]},"finish_reason":"tool_calls"}]}
+{"object":"chat.completion","id":"chatcmpl-session-123","created":1739430010,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","content":"Fix completed; the file has been updated."},"finish_reason":"stop"}],"usage":{"prompt_tokens":1600,"completion_tokens":200,"total_tokens":1800}}
+```
+
+### `stream-chunk-json` Behavior Highlights
+
+- First line sends `{"object":"chat.completion.chunk","choices":[{"delta":{"role":"assistant"}}]}` to declare the role.
+- Outputs text tokens, tool call increments, and `tool_calls` updates as needed.
+- Final line includes `{"choices":[{"delta":{},"finish_reason":"stop"}]}` and attaches a summary in `usage` or `metadata`.
+- Optional `annotations` and `spans` fields describe terminal styling (see below).
+
+## Event Payloads and Annotations
+
+`packages/cli/src/nonInteractiveCli.ts` and `packages/cli/src/ui/utils/ConsolePatcher.ts` jointly decide how text-mode output is produced: model content is appended to `stdout` via `GeminiEventType.Content`, tool execution state and logs are printed to `stderr` through `ConsolePatcher`, and tool result structures (`ToolResultDisplay`, etc.) are rendered by `packages/cli/src/ui/hooks/useReactToolScheduler.ts`. To ensure `stream-json` / `stream-chunk-json` covers every semantic, we reuse the OpenAI `annotations` field with the following conventions:
+
+| Type | Key Fields | Purpose |
+| --- | --- | --- |
+| `chat.completion.chunk` annotation | `annotations`, `spans` | Reproduce terminal styling, ANSI control codes, and origin labels |
+| `x-qwen-terminal` | `channel`, `source`, `console_level`, `ansi` | Output terminal streams (stdout/stderr/console/system) |
+| `x-qwen-tool-display` | `tool_call_id`, `status`, `result_display` | Present tool diffs, strings, TODOs, plan summaries, task execution, etc. |
+| `x-qwen-thought` | `subject`, `description` | Show thinking prompts (GeminiEventType.Thought) |
+| `x-qwen-session-event` | `event`, `message`, `metrics` | Session-level notifications such as compression, cancellation, and token limits |
+
+### Terminal Annotation Structure
+
+```json
+{
+ "type": "x-qwen-terminal",
+ "channel": "stdout",
+ "source": "assistant",
+ "spans": [
+ {"start": 0, "end": 24, "style": {"theme_token": "AccentGreen"}}
+ ],
+ "ansi": [
+ {"offset": 0, "code": "\u001b[32m"},
+ {"offset": 24, "code": "\u001b[0m"}
+ ],
+ "console_level": "info",
+ "exit_code": null,
+ "prompt_id": "session-123########7"
+}
+```
+
+- `channel`: `stdout` / `stderr`; console logs use `ConsolePatcher` to inject `stderr` with `console_level`.
+- `source`: `assistant`, `tool`, `console`, `system`, enabling layered display on the frontend.
+- `spans.style.theme_token`: Reuse CLI themes (`AccentGreen`, `DiffAdded`, etc.).
+- `ansi`: Positions of raw ANSI sequences for frontends to replay.
+- `console_level`: When `source=console`, takes values `log`, `warn`, `error`, `info`, or `debug` so that downstream consumers can mirror `ConsolePatcher` behavior.
+- `exit_code`: Provided when `source=system` and the flow finishes.
+- `prompt_id`: Associates the record with a specific turn.
+
+### Tool Result Display
+
+```json
+{
+ "type": "x-qwen-tool-display",
+ "tool_call_id": "call_tool-1",
+ "session_id": "session-123",
+ "status": "executing",
+ "result_display": {
+ "kind": "file_diff",
+ "file_name": "src/main.py",
+ "diff": "--- a/src/main.py\n+++ b/src/main.py\n@@ -1 +1 @@\n-print('Hi')\n+print('Hello')",
+ "original": "print('Hi')\n",
+ "modified": "print('Hello')\n",
+ "stat": {
+ "ai_added_lines": 1,
+ "ai_removed_lines": 1,
+ "user_added_lines": 0,
+ "user_removed_lines": 0
+ }
+ },
+ "confirmation": null,
+ "pending": false,
+ "timestamp": 1739430005
+}
+```
+
+- `status` follows `ToolCallStatus` (`Pending`, `Executing`, `Success`, `Error`, `Canceled`, `Confirming`).
+- `tool_call_id` reuses the OpenAI schema field; together with `session_id` it uniquely locates a call, and can be reused even in test/non-session modes.
+- `result_display` supports unions such as `string`, `file_diff`, `todo_list`, `plan_summary`, and `task_execution`.
+- `confirmation` serializes the relevant `ToolCallConfirmationDetails` (diffs, commands, MCP payloads) so third parties can surface approval dialogs.
+- `pending=true` indicates the call is still validating/queued and matches `ToolCallStatus.Pending`.
+- `timestamp` is used for ordering and matches records from `useReactToolScheduler`.
+
+### Thought and Session Events
+
+```json
+{
+ "type": "x-qwen-thought",
+ "subject": "Analyzing repo",
+ "description": "Listing tsconfig patterns..."
+}
+```
+
+```json
+{
+ "type": "x-qwen-session-event",
+ "event": "MAX_TOKENS",
+ "message": "Response truncated due to token limits.",
+ "metrics": {
+ "original_tokens": 12000,
+ "compressed_tokens": 8000
+ }
+}
+```
+
+- `event` values derive from `GeminiEventType`, including `Finished`, `ChatCompressed`, `MaxSessionTurns`, `USER_CANCELLED`, etc.
+- `metrics` optionally provide statistics such as tokens before and after compression.
+
+## Input Format (Qwen Session Protocol)
+
+| Mode | Behavior | Notes |
+| --- | --- | --- |
+| `text` | Preserve original TUI text input | Parse natural language or command-line text |
+| `stream-json` / `stream-chunk-json` | Use Qwen Chat Request | Each JSON line describes one incremental input |
+
+### Qwen Chat Request Mode
+
+```jsonc
+{
+ "session_id": "session-123",
+ "prompt_id": "session-123########7",
+ "model": "qwen-coder",
+ "input": {
+ "origin": "user",
+ "parts": [
+ {"type": "text", "text": "Please fix the bug in @main.py"}
+ ],
+ "command": null
+ },
+ "options": {
+ "temperature": 0.2,
+ "tool_overrides": ["EditTool"]
+ }
+}
+```
+
+- `session_id`: Session identifier (`config.getSessionId()`); pass `"_new"` to create a new session.
+- `prompt_id`: Distinguishes turns; default format `########`, and must be reused when tools continue the conversation.
+- `input.origin`: `user` / `tool_response` / `system`, determining how the session continues.
+- `input.parts`: Compatible with `@google/genai` PartListUnion, allowing `text`, `function_response`, `file_data`, etc. When `origin="user"`, the CLI concatenates all text parts in order and reuses the same semantics as `prepareQueryForGemini`.
+- `options`: Per-request overrides (model, sampling, tool allowlist).
+- Extended fields:
+ - `tool_call_id`: Required when `origin=tool_response` to match output events.
+ - `continuation`: Boolean equivalent to `submitQuery(...,{isContinuation:true})`; if omitted, the CLI infers continuation based on `origin` and command context.
+ - `tool_request`: Mirrors `ToolCallRequestInfo` to support concurrent tools and sub-agents.
+
+### Session Control
+
+- Third parties may invoke the CLI’s “create session” command or reuse an existing ID; when `session_id` is missing or set to `"_new"`, the CLI returns the actual ID in the first `chat.completion`.
+- `prompt_id` and `tool_call_id` together isolate concurrent flows; reuse them for tool continuations. The default format is `########`, but any unique identifier is acceptable.
+- Sending `input.origin="system"` with parts such as `{"type":"instruction","text":"/clear"}` triggers slash commands exactly as in the TUI.
+- When `origin="tool_response"`, `tool_call_id` is mandatory so the CLI can attach results to the correct turn before proceeding.
+
+### Commands and `@` References
+
+| Mode | Trigger Method | Behavior |
+| --- | --- | --- |
+| Implicit Parsing | `origin="user"` with text starting with `/`/`?`/`@` | CLI automatically follows the slash/at flow, invoking logic such as `handleAtCommand` |
+| Explicit Declaration | Describe the command in `input.command` | Recommended for third parties to avoid string parsing ambiguities |
+
+- `command.kind`: `slash` / `at`, matching the TUI command taxonomy.
+- `command.path`: For slash commands, represents the hierarchical command array (mirrors `commandPath`); omit for `at`.
+- `command.args`: Remaining argument string that the CLI will parse exactly as in TUI mode.
+- `command.references`: When `kind="at"`, can directly provide resolved references such as `{ "original":"@src/main.ts", "resolved":"src/main.ts" }`; if omitted, the CLI falls back to `handleAtCommand` and `useAtCompletion` for automatic resolution.
+
+Explicit command example:
+
+```jsonc
+{
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": ""}],
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ }
+ }
+}
+```
+
+- CLI outputs the corresponding `result/command`:
+
+```jsonc
+{
+ "type": "result/command",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ },
+ "result": {
+ "type": "message",
+ "level": "info",
+ "content": "The current session has 3 history records."
+ }
+}
+```
+
+- `command.result.type` supports enums such as `message`, `dialog`, `tool`, and `submit_prompt` for easier UI rendering.
+- If the command triggers a model call, subsequent output includes `assistant`, `tool_call`, and `result/*` events, following the same order as the TUI.
+
+Explicit `@` reference example:
+
+```jsonc
+{
+ "session_id": "session-123",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": "Please review @src/main.py"}],
+ "command": {
+ "kind": "at",
+ "references": [
+ {"original": "@src/main.py", "resolved": "src/main.py"}
+ ]
+ }
+ }
+}
+```
+
+- The CLI uses the explicit `references` to read files; if missing, it falls back to automatic parsing, preserving TUI tolerance for partial paths.
+
+### SDK-Side Command Coordination
+
+| `command.result.type` | Description | SDK Guidance |
+| --- | --- | --- |
+| `handled` | Command completed fully inside the CLI | No extra action |
+| `message` | Informational or error message | Display a notification in the UI |
+| `dialog` (`auth`/`theme`/`editor`/`privacy`/`settings`/`model`/`subagent_create`/`subagent_list`/`help`) | Requires dialogs or navigation | Present the appropriate UI panel |
+| `tool` | Triggers a tool call | Convert `tool_request` or command args into a tool request and monitor results |
+| `submit_prompt` | Immediately sends a PartListUnion to the model | Submit `content` as the next input with `continuation=true` |
+| `load_history` | Reset or load specified session history | Refresh or reload history views |
+| `quit` / `quit_confirmation` | Exit flow or await user confirmation | Control the host app lifecycle and return confirmation |
+| `confirm_shell_commands` | Shell commands awaiting approval | Show an approval dialog; resend with `approvedCommands` / `confirmationOutcome` once approved |
+| `confirm_action` | General confirmation prompt | Provide confirmation UI and return the outcome |
+
+- SDKs should expose a unified command API that maps user input to the structure above and drives local UI or follow-up requests based on the resulting action.
+- When commands kick off further model interactions (e.g., `/submit`, expanded `@file`), the CLI keeps streaming `assistant`, `tool_call`, and `result/*` events in the same order as the TUI, letting third parties replicate the interaction with pure text input plus JSON output.
+
+### STDIN Command Acknowledgement
+
+- With `--input-format=stream-json`, the CLI must still acknowledge `/`, `?`, and `@` commands immediately, reusing `useSlashCommandProcessor` and `handleAtCommand`.
+- After parsing, the CLI emits structured responses such as:
+
+```jsonc
+{
+ "type": "result/command",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ },
+ "result": {
+ "type": "message",
+ "level": "info",
+ "content": "The current session has 3 history records."
+ }
+}
+```
+
+- The `result` field matches the `command.result.type` table above for consistent UI handling.
+- If commands lead to continued interaction, the CLI streams the rest of the turn with matching session fields.
+CLI outputs the corresponding `result/command`:
+
+```jsonc
+{
+ "type": "result/command",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ },
+ "result": {
+ "type": "message",
+ "level": "info",
+ "content": "The current session has 3 history records."
+ }
+}
+```
+
+- `command.result.type` supports enums such as `message`, `dialog`, `tool`, and `submit_prompt` for easier UI rendering.
+- If the command triggers a model call, subsequent output includes `assistant`, `tool_call`, and `result/*` events, following the same order as the TUI.
+
+## Real-Time Suggestions, Heartbeats, and Interrupts
+
+| Capability | Request | Response | Notes |
+| --- | --- | --- | --- |
+| Command Suggestions | `command_hint_request` | `result/command_hint` | Triggered by characters; `trigger` supports `slash`, `at`; `status` can be `ok` / `loading` / `error` |
+| Heartbeat | `heartbeat_request` | `result/heartbeat` | Periodic keepalive; the CLI may proactively push the same event |
+| Interrupt/Cancel | `control/cancel` | `result/cancel` + `control_response` | Simulates ESC; `reason` is currently fixed at `escape` |
+
+### Suggestion Request Example (`/c`)
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/c",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### Suggestion Response Example
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {"label": "chat", "value": "chat", "description": "Manage conversation history."},
+ {"label": "clear", "value": "clear", "description": "Clear the screen and conversation history."},
+ {"label": "compress", "value": "compress", "description": "Compresses the context by replacing it with a summary."},
+ {"label": "copy", "value": "copy", "description": "Copy the last result or code snippet to clipboard."},
+ {"label": "corgi", "value": "corgi", "description": "Toggles corgi mode."}
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+}
+```
+
+### Suggestion Request Example (`@src/co`)
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "text": "@src/co",
+ "cursor": 7,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### Suggestion Response Example (`@src/co`)
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "status": "ok",
+ "suggestions": [
+ {"label": "src/components/", "value": "src/components/"},
+ {"label": "src/components/Button.tsx", "value": "src/components/Button.tsx"},
+ {"label": "src/components/Button with spaces.tsx", "value": "src/components/Button\\ with\\ spaces.tsx"}
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+}
+```
+
+### Suggestion Request Example (`/?`)
+
+```jsonc
+{
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/?",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+}
+```
+
+### Suggestion Response Example (`/?`)
+
+```jsonc
+{
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {
+ "label": "help",
+ "value": "help",
+ "description": "For help on Qwen Code.",
+ "matchedIndex": 0
+ }
+ ],
+ "metadata": {
+ "is_perfect_match": true
+ }
+}
+```
+
+- `suggestions` reuse the TUI `Suggestion` structure; `status="loading"` indicates the CLI is preparing data (for example while `useAtCompletion` builds the file index), and `error` responses include a message.
+- The CLI reuses `useSlashCompletion` and `useAtCompletion` to generate hints; these requests never touch `GeminiChat` nor session history, and `prompt_id` may carry a `_preview` suffix that is echoed back.
+- Triggers can fire repeatedly as the text or cursor changes; send `{"type":"command_hint_cancel", ...}` to stop long-running lookups.
+
+### Heartbeat Request and Response
+
+```jsonc
+{"type":"heartbeat_request","session_id":"session-123"}
+{"type":"result/heartbeat","session_id":"session-123","status":"ok","ts":1739430123}
+```
+
+- Third parties can configure timeouts (e.g., 10 seconds) to detect CLI hangs and restart the process.
+- The CLI responds with the same `result/heartbeat` shape and may proactively push keepalive events in the background.
+- `@third-party/anthropics/claude-agent-sdk-python` currently lacks a heartbeat implementation; the P1.1 rollout must define default intervals, timeout policy, and whether SDKs can customize the heartbeat cadence.
+
+### Interrupt Example
+
+```jsonc
+{
+ "type": "control/cancel",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "reason": "escape"
+}
+```
+
+- The CLI must call `cancelOngoingRequest`, abort the `AbortController`, finalize history items, and emit `result/cancel`.
+- If no request can be canceled, the CLI should return `{"type":"result/cancel","status":"noop"}` with an explanation.
+- When the underlying stream reports `GeminiEventType.UserCancelled`, the CLI also emits `{"type":"x-qwen-session-event","event":"USER_CANCELLED","message":"User cancelled the request."}` so clients can update the session state.
+- Double-tapping ESC to clear the input is handled on the client side; structured integrations can replicate that locally without sending additional CLI messages.
+
+## Event Categories and Channels
+
+| Category | Direction | Representative Events | Acknowledgment Requirement | Purpose |
+| --- | --- | --- | --- | --- |
+| Result Events | CLI → STDOUT | `result/command`, `result/command_hint`, `result/heartbeat`, `result/cancel`, `x-qwen-session-event` | No acknowledgment required | Publish command output, status tips, heartbeat results |
+| Request Events | SDK/Third Party → STDIN | `command_hint_request`, `heartbeat_request`, `control/cancel` | CLI returns the corresponding `result/*` | Trigger immediate actions or controls |
+| Control Channel | CLI ↔ STDIN/STDOUT | `control_request` / `control_response` | Must match `request_id` | Permission approvals, hook callbacks, MCP calls |
+
+These categories can also be viewed as three event mechanisms:
+
+1. **Result events (`result/*`)**
+ - CLI → STDOUT one-way announcements such as `result/command`, `result/command_hint`, `result/heartbeat`, `result/cancel`, `x-qwen-session-event`.
+ - Carry command output, hints, heartbeat results, and session state updates. No acknowledgment is required.
+
+2. **Request events (`*request`)**
+ - SDK/third party → STDIN directives like `command_hint_request`, `heartbeat_request`, or `control/cancel`.
+ - Trigger immediate CLI behavior, and each request must be answered with the corresponding `result/*`.
+
+3. **Control channel events (`control_request` / `control_response`)**
+ - CLI outputs `control_request`, external integrations respond with matching `control_response`; used for approvals, hook callbacks, MCP JSON-RPC, etc.
+ - Each carries a unique `request_id`, requires timely responses, and bypasses conversation history to stay in sync with TUI behavior.
+
+- All events travel over a unified JSON Lines protocol; route them by `type`/`subtype`.
+- Control channel participants must implement timeout and error fallback strategies to avoid blocking the CLI.
+
+## Control Requests and Responses
+
+| Field | Description |
+| --- | --- |
+| `type` | Always `control_request` or `control_response` |
+| `request_id` | Unique identifier pairing requests with responses |
+| `subtype` | `can_use_tool`, `hook_callback`, `mcp_message`, etc. |
+| `payload` / `response` | Carries event details or acknowledgment content |
+
+- `control_request` example:
+
+```jsonc
+{
+ "type": "control_request",
+ "request_id": "req-1",
+ "subtype": "can_use_tool",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "tool": {
+ "name": "edit_file",
+ "arguments": {"path": "main.py", "patch": "..."}
+ },
+ "metadata": {
+ "reason": "apply_diff"
+ }
+}
+```
+
+- Corresponding `control_response`:
+
+```jsonc
+{
+ "type": "control_response",
+ "request_id": "req-1",
+ "response": {
+ "subtype": "success",
+ "result": {
+ "behavior": "approve",
+ "message": "Allowed to execute."
+ }
+ }
+}
+```
+
+- If a callback fails, the SDK must return `{"subtype":"error","error":{"message":"...","retryable":false}}`, and the CLI will follow the safety fallback (auto-deny or report failure).
+- MCP integration: `subtype:"mcp_message"` carries JSON-RPC (`tools/list`, `tools/call`, etc.), and the SDK wraps results as `mcp_response` inside `control_response`.
+- Current state: the CLI primarily emits one-way output while the TUI handles confirmations inline, so dual-channel hooks similar to Claude Code still need to be generalized.
+- Design requirement: whenever the CLI needs external confirmation, it should emit a `control_request` and wait for the matching `control_response`, covering tool approvals, hook callbacks, and MCP JSON-RPC exchanges.
+- Coverage examples: `/confirm_shell_commands`, `confirm_action`, `quit_confirmation`, tool permission approvals, sub-agent orchestration, and future dialogs/forms/identity flows.
+- Fallback policy: if the control channel is disabled, the CLI must explicitly reject risky actions or state “unavailable in structured mode” via `result/command` instead of failing silently.
+- Follow-up tasks: (1) add JSON Schemas for `control_request` / `control_response`; (2) build a unified dispatcher so the TUI and CLI share the same logic; (3) extend SDKs with listeners/hooks that surface the requests to upper-layer UIs.
+
+## Version Negotiation and Error Semantics
+
+| Item | Description |
+| --- | --- |
+| Protocol Version | The first `chat.completion` includes `protocol_version`, `input_format`, `output_format`, and `capabilities` in `metadata` / `system_fingerprint` |
+| Version Mismatch | If the SDK requests unsupported features, the CLI returns `finish_reason="error"`, marks `unsupported_protocol` in `metadata.error`, and exits with a non-zero code |
+| Fatal Errors | Emit OpenAI-style error objects and terminate |
+| Recoverable Errors | Return error details via `chat.completion` with `finish_reason` `stop/tool_calls` while keeping the process healthy |
+| Control Protocol Errors | Attach details in `metadata.control_errors` so the SDK can decide whether to retry or terminate |
+
+Fatal error example:
+
+```json
+{
+ "error": {
+ "message": "invalid tool input",
+ "type": "invalid_request_error",
+ "param": "tools[0].function.arguments",
+ "code": "QWEN_INVALID_TOOL_ARGS"
+ }
+}
+```
+
+## Security and Resource Control
+
+| Domain | Policy |
+| --- | --- |
+| Permissions | Structured mode still honors existing CLI approval and tool allowlists; high-risk actions default to denial without acknowledgement |
+| Audit | Control channel lets the SDK audit sensitive operations beforehand; if disabled, `result/command` must state the limitation explicitly |
+| Keepalive | `heartbeat` events can trigger process recycling to avoid resource leaks |
+
+## Logging Layers and Observability
+
+| Component | Highlights |
+| --- | --- |
+| ConsolePatcher | Intercepts `console.*`, records `channel="stderr"` and `console_level` within `x-qwen-terminal` |
+| `log_scope` extension | Recommend attaching `log_scope` (`system`, `tool`, `debug`) to annotations in structured mode to align with `ConfigLogger` levels |
+| Tool Logs | Output via `ToolResultDisplay`; `result_display` can carry `log_scope` for filtering |
+| OTel Plan | SDK and CLI each integrate OpenTelemetry to chain traces and spans |
+
+- Third parties are advised to store the full message sequence in audit logs for replay.
+
+## Debugging Examples
+
+```bash
+echo '{"model":"qwen-coder","messages":[{"role":"user","content":"Hello"}]}' \
+ | qwen --input-format stream-json --output-format stream-json
+
+echo '{"model":"qwen-coder","messages":[{"role":"user","content":"Output the greeting character by character."}]}' \
+ | qwen --input-format stream-json --output-format stream-chunk-json
+```
+
+- Use these commands to quickly verify output formats and event flows.

+# RFC: Qwen-Code CLI 输出格式与 IPC Stream JSON 能力
+
+- **状态**: Draft
+- **更新时间**: 2025-10-13
+- **作者**: x22x22
+- **追踪**:
+
+## 摘要
+
+为了支撑第三方系统以编程方式稳定集成 Qwen-Code，本 RFC 旨在定义并实现 CLI 层的结构化输入/输出能力。核心改动是在现有 CLI 上引入 `--input-format/--output-format`（`text`/`stream-json`/`stream-chunk-json`）与对称的结构化输入协议，配套 JSON Lines、错误语义、会话字段及分阶段落地计划。这一能力是 IPC SDK、第三方后端服务、UI 组件以及多语言 SDK 协同工作的基础，可直接回应 issue #795 关于“提供 `--input-format/--output-format json/stream-json`”的诉求，并与现有架构设计保持一致。
+
+## 背景
+
+### Issue 795 概述
+
+社区提出希望参考 Claude Code 的实现，为 Qwen-Code CLI 增加 `--input-format/--output-format json/stream-json`，以便第三方程序可以无 UI 干预地消费 CLI 输出，构建可自动化的集成能力。
+
+### 集成方场景
+
+1. task级别的集成，即通过sdk一条条发送prompt，中间接收多次数据并进行处理后再返回给用户展示。
+2. task级别的集成，即通过sdk一条条发送prompt，直接流式返回给用户展示。
+3. 在输入框中输入指令(/,@,?)需要和在TUI中一样要有反应。
+4. 使用类似xterm.js的库在前端模拟终端交互，但是输入框和终端内容是分离的。
+
+### 集成方式
+
+1. 第三方程序依赖后期提供的各个语言的"qwen-code-agent-sdk"；
+2. "qwen-code-agent-sdk"使用子进程方式启动"qwen code"，并基于stdio进行双向IPC通信；
+3. "qwen-code-agent-sdk"接收"qwen code"执行的结果；
+4. 第三方程序获取到"qwen-code-agent-sdk"的结果。
+
+### 现状痛点
+
+1. CLI 仅支持人机交互式的纯文本 STDOUT，输出不稳定。
+2. 没有对称的结构化输入，难以驱动高级自动化流程。
+
+## 设计目标
+
+1. 在 CLI 层提供稳定可配置的输出格式选项，默认兼容现有行为。
+2. 实现 JSON Lines 流式协议，匹配 IPC SDK 设计中的消息语义与控制协议。
+3. 提供对称的结构化输入能力，支持 SDK 将提示与控制消息写入 STDIN。
+4. 定义跨语言可共用的schema、错误语义。
+5. 为后期需要实现的qwen-code-agent-sdk友好化考虑。
+
+## 非目标
+
+- 不在本 RFC 中体现 SDK 的设计。
+
+## 方案概览
+
+### CLI 参数设计
+
+| 参数 | 取值 | 默认值 | 说明 |
+|------|------|--------|------|
+| `--input-format` | `text` / `stream-json` | `text` | 控制 STDIN 解析逻辑 |
+| `--output-format` | `text` / `stream-json` / `stream-chunk-json` | `text` | 控制 STDOUT 输出格式 |
+| *(自动)* | | | 当 `--input-format/--output-format` 取值为 `stream-json` / `stream-chunk-json` 时，CLI 自动禁用 TUI，进入结构化输出模式；仅 `text` 模式保留原有 TUI 行为。**通信仍通过标准输入/输出管道完成，未改用额外通道** |
+
+CLI 参数在帮助信息中展示，且 `text` 模式沿用现有行为，保证向后兼容。无需额外的 `--stdio` 开关。
+
+### 输出格式语义
+
+1. **`text`（兼容模式）**
+ - 沿用当前 STDOUT 逻辑，适用人类交互。
+ - 不保证结构化信息；未来将逐步标记为“仅供手动使用”。
+
+2. **`stream-json`（消息级 JSON Lines）**
+ - 每行输出一个符合 OpenAI `/chat/completions` 响应格式的对象，`object` 固定为 `chat.completion`。
+ - CLI 会在同一个流程中依次输出：初始化回执（含能力声明）、每次助手回复/工具调用的 `chat.completion` 对象、收尾摘要。
+ - 示例：
+ ```json
+ {"object":"chat.completion","id":"chatcmpl-session-123","created":1739430000,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","content":"正在分析...","tool_calls":null},"finish_reason":"stop"}],"usage":{"prompt_tokens":1200,"completion_tokens":80,"total_tokens":1280}}
+ {"object":"chat.completion","id":"chatcmpl-session-123","created":1739430002,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","tool_calls":[{"id":"tool-1","type":"function","function":{"name":"edit_file","arguments":"..."}}]},"finish_reason":"tool_calls"}]}
+ {"object":"chat.completion","id":"chatcmpl-session-123","created":1739430010,"model":"qwen-coder","choices":[{"index":0,"message":{"role":"assistant","content":"修复完成，已更新文件。"},"finish_reason":"stop"}],"usage":{"prompt_tokens":1600,"completion_tokens":200,"total_tokens":1800}}
+ ```
+ - 仍保持 JSONL 逐行输出，方便 第三方后端服务、SDK 以消息级颗粒度消费。
+
+3. **`stream-chunk-json`（增量 chunk JSON Lines）**
+ - 输出遵循 OpenAI 流式响应格式；每行一个 `chat.completion.chunk` 对象，`choices[].delta` 承载 token/块增量，同一 `id` 覆盖整个会话。
+ - CLI 会在开头发送带 `delta: {}` 的 `role` 声明，过程中发送文本或工具调用增量，最后输出仅含 `finish_reason`（以及可选 `usage`）的结束 chunk，与 OpenAI `/chat/completions` 规范保持一致。
+ - 示例：
+ ```json
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430000,"model":"qwen-coder","choices":[{"index":0,"delta":{"role":"assistant"}}]}
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430001,"model":"qwen-coder","choices":[{"index":0,"delta":{"content":"正在"}},{"index":1,"delta":{"content":""}}]}
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430001,"model":"qwen-coder","choices":[{"index":0,"delta":{"content":"分析..."},"finish_reason":null}]}
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430003,"model":"qwen-coder","choices":[{"index":0,"delta":{"tool_calls":[{"id":"tool-1","type":"function","function":{"name":"edit_file","arguments":"..."}}]}}]}
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430008,"model":"qwen-coder","choices":[{"index":0,"delta":{},"finish_reason":"stop"}]}}
+ {"object":"chat.completion.chunk","id":"chatcmpl-session-123","created":1739430008,"model":"qwen-coder","usage":{"prompt_tokens":1600,"completion_tokens":200,"total_tokens":1800},"choices":[]}
+ ```
+ - 不再额外补发完整 `chat.completion`，而是在最后的 chunk 中给出 `finish_reason` 与可选 `usage`，符合 OpenAI 文档（见 `@third-party/code-cli-any-llm/docs/research/completions.chat.openapi.documented.yml`）的结尾语义。
+
+#### 消费策略
+
+- **消息级 JSONL (`stream-json`)**: 适合需要稳定阶段性结果的 第三方后端服务 或 CLI 包装器，默认采用此模式，与现有 JSONL 管线兼容。
+- **增量 chunk (`stream-chunk-json`)**: 适合 IDE / UI 组件的“边生成边展示”场景；SDK 需监听 `chat.completion.chunk`，并在接收到最终 `finish_reason` 后处理总结对象。
+- **前端模拟终端关系**: 无论 CLI 原始模式为文本还是结构化输出，SDK 均可统一消费 `chat.completion` / `chat.completion.chunk` 序列。从 CLI 角度，`stream-json` 与 `stream-chunk-json` 必须完整覆盖 TUI 模式会写入标准输出的全部语义信息（文本、ANSI/Vt100 控制、工具提示、退出码等），并通过 `choices[].message.content` / `choices[].delta.content` 与 `choices[].delta.annotations`（示例：`{"type":"x-qwen-ansi","value":"\u001b[32m"}`）进行编码。这样第三方即可在基于 xterm.js 的终端里还原颜色、光标移动、逐步输出等效果，而无需依赖 `text` 模式。
+
+### 前端模拟终端注解（annotations）
+
+`packages/cli/src/nonInteractiveCli.ts` 与 `packages/cli/src/ui/utils/ConsolePatcher.ts` 共同决定了文本模式输出的来源：模型内容通过 `GeminiEventType.Content` 追加到 `stdout`；工具执行状态、错误与日志通过 `ConsolePatcher` 打印至 `stderr`；工具结果结构体 (`ToolResultDisplay` 等) 则在 `packages/cli/src/ui/hooks/useReactToolScheduler.ts` 中驱动 UI 渲染。为保证 `stream-json` / `stream-chunk-json` 能完整覆盖这些信息，我们在 OpenAI `annotations` 字段上新增以下约定：
+
+| 注解类型 | 作用 | 对应代码来源 |
+|----------|------|--------------|
+| `x-qwen-terminal` | 描述终端通道、样式与 ANSI/Vt100 控制序列 | `process.stdout.write`/`process.stderr.write` 拦截 (`nonInteractiveCli.ts`) + `ConsolePatcher` |
+| `x-qwen-tool-display` | 携带工具执行过程/结果的结构化数据 | `ToolResultDisplay`/`ToolCallStatus` (`packages/core/src/tools/tools.ts`, `packages/cli/src/ui/hooks/useReactToolScheduler.ts`) |
+| `x-qwen-thought` | 暴露 `GeminiEventType.Thought` 推理摘要 | `packages/core/src/core/turn.ts` |
+| `x-qwen-session-event` | 包含 `Finished`、`ChatCompressed` 等控制事件的人类可读提示 | `packages/core/src/core/turn.ts` + `useGeminiStream.ts` |
+
+#### `x-qwen-terminal`
+
+```json
+{
+ "type": "x-qwen-terminal",
+ "channel": "stdout",
+ "source": "assistant",
+ "spans": [
+ {
+ "start_index": 0,
+ "end_index": 5,
+ "style": {
+ "theme_token": "AccentGreen",
+ "bold": false
+ }
+ }
+ ],
+ "ansi": [
+ {"offset": 0, "sequence": "\u001b[32m"},
+ {"offset": 5, "sequence": "\u001b[0m"}
+ ]
+}
+```
+
+- `channel`: `stdout` / `stderr`（日志与错误来自 `ConsolePatcher` 会标记为 `stderr`，同时附带 `console_level` 字段以区分 `log`/`warn`/`error`）。
+- `source`: `assistant`（模型输出）、`tool`（工具实时输出/结果）、`console`（`console.*` 调用）、`system`（启动/关闭/致命错误）。
+- `spans.style.theme_token`: 直接复用 `Colors` 主题枚举（如 `AccentGreen`、`DiffAdded`，定义于 `packages/cli/src/ui/colors.ts` 与 `themes/*.ts`），第三方可映射为自定义调色板。
+- `ansi`: 原始 ANSI 序列与其在内容中的偏移，便于 xterm.js 原样重放；若无 ANSI 控制，数组可为空。
+- 附加字段：
+ - `console_level`: 当 `source = console` 时，为 `log` / `warn` / `error` / `info` / `debug`。
+ - `exit_code`: 当 `source = system` 且流程结束时给出。
+ - `prompt_id`: 若可关联到某次用户输入/回合（`nonInteractiveCli.ts` 中的 `prompt_id`），用于跨消息聚合。
+
+> 示例：`packages/cli/index.ts` 中 `FatalError` 会输出红色字体；在 `stream-chunk-json` 中表现为 `delta.content:"配置缺失"` + `annotations:[{type:"x-qwen-terminal",channel:"stderr",source:"system",ansi:[...]}]`。
+
+#### `x-qwen-tool-display`
+
+```json
+{
+ "type": "x-qwen-tool-display",
+ "tool_call_id": "call_tool-1",
+ "session_id": "session-123",
+ "status": "executing",
+ "result_display": {
+ "kind": "file_diff",
+ "file_name": "src/main.py",
+ "diff": "--- a/src/main.py\n+++ b/src/main.py\n@@ -1 +1 @@\n-print('Hi')\n+print('Hello')",
+ "original": "print('Hi')\n",
+ "modified": "print('Hello')\n",
+ "stat": {
+ "ai_added_lines": 1,
+ "ai_removed_lines": 1,
+ "user_added_lines": 0,
+ "user_removed_lines": 0
+ }
+ }
+}
+```
+
+- `status`: 映射自 `ToolCallStatus`（`Pending`，`Executing`，`Success`，`Error`，`Canceled`，`Confirming`），见 `packages/cli/src/ui/types.ts`。
+- `tool_call_id`: 复用 OpenAI schema 字段名，结合 `session_id` 可唯一定位某次调用，便于第三方将多个调用分区展示。若 CLI 处于测试/非会话模式，可仅使用 `tool_call_id`。
+- `result_display` union：
+ - `kind: "string"` → `{ "text": "stdout captured..." }`。
+ - `kind: "file_diff"` → `FileDiff` 字段集合。
+ - `kind: "todo_list"` → `{ "todos": [{id, content, status}] }`（源自 `TodoResultDisplay`）。
+ - `kind: "plan_summary"` → `{ "message": "...", "plan_markdown": "..."}`
+ - `kind: "task_execution"` → 直接映射 `TaskResultDisplay`（包含 `subagentName`、`status`、`toolCalls` 等）。
+- `confirmation`: 若 `ToolCallConfirmationDetails` 仍待用户确认（`type: 'edit'|'exec'|'mcp'|'info'|'plan'`），序列化必要字段（例如 diff、命令、提示等），便于第三方弹窗。
+- `pending`: 布尔值，表示调用仍在 `validating`/`scheduled` 状态，尚未交给执行器；用于第三方提前占位，与 `ToolCallStatus.Pending` 等价。
+- `timestamp`: 可选毫秒级时间戳，对应 `useReactToolScheduler` 中的历史写入时间，便于排序。
+
+#### `x-qwen-thought`
+
+```json
+{
+ "type": "x-qwen-thought",
+ "subject": "Analyzing repo",
+ "description": "Listing tsconfig patterns..."
+}
+```
+
+- 对应 `GeminiEventType.Thought` 推理摘要（`packages/core/src/core/turn.ts` 第 250 行），在 UI 中常用于“思考中”提示。
+
+#### `x-qwen-session-event`
+
+用于承载会话级事件（`Finished`、`ChatCompressed`、`SessionTokenLimitExceeded` 等）的人类可读提示，字段包括：
+
+```json
+{
+ "type": "x-qwen-session-event",
+ "event": "MAX_TOKENS",
+ "message": "Response truncated due to token limits.",
+ "metrics": {
+ "original_tokens": 12000,
+ "compressed_tokens": 8000
+ }
+}
+```
+
+`event` 取值来自 `GeminiEventType`（`Finished`、`ChatCompressed`、`MaxSessionTurns` 等），`message` 为 UI 在 `useGeminiStream.ts` 中构造的提示文案。当用户或集成方触发 ESC 取消时，CLI 需发送 `event: "USER_CANCELLED"`、`message: "User cancelled the request."`，保持与 TUI 一致。
+
+### 输入格式语义（Qwen 会话协议）
+
+> 传输层保持与现有 CLI 相同：所有结构化输入仍以 `\n` 结尾的 JSON 行写入 STDIN，CLI 侧按照 `--input-format` 选择解析器。该模式直接参考了 `@anthropics/claude-agent-sdk-python` 中的 `SubprocessCLITransport` 实现，后者同样在流式模式下对每条消息 `json.dumps(...)` 后写入子进程 STDIN。
+
+- `text`: 与现有模式一致，从 STDIN 读取自然语言指令，维持原始 TUI 行为。
+- `stream-json` / `stream-chunk-json`: CLI 期望每行输入遵循 **Qwen Chat Request** 协议。该协议借鉴 OpenAI `/chat/completions` 的结构，但不会要求调用方重复发送完整历史，而是仅提交“本次增量”。CLI 通过 session ID 与内部 `GeminiChat` 历史（参见 `GeminiChat.sendMessageStream`）维护上下文。
+
+#### Qwen Chat Request 结构
+
+```jsonc
+{
+ "session_id": "session-123", // 必填, 由 CLI/SDK 生成或复用
+ "prompt_id": "session-123########7", // 可选, 不传时 CLI 自动生成; 与工具调用关联时需复用
+ "model": "qwen-coder", // 可选, 为空时沿用当前会话模型
+ "input": {
+ "origin": "user", // user | tool_response | system
+ "parts": [ // 与 @google/genai PartListUnion 对齐
+ {"type": "text", "text": "请修复 @main.py 的 bug"}
+ ],
+ "command": null // 可选, 显式声明 slash/@ 命令 (见下文)
+ },
+ "options": {
+ "temperature": 0.2,
+ "tool_overrides": ["EditTool"]
+ }
+}
+```
+
+- `session_id`: 对应 `config.getSessionId()`，是所有会话状态的主键。第三方可调用 CLI 提供的“创建会话”命令获取，或复用现有 TUI 生成的 ID。
+- `prompt_id`: 用于标识一次用户输入或工具续写；同一个 `prompt_id` 下可能经历多轮工具调用。CLI 默认格式为 `########`，第三方可复用该格式或自定义但需保持唯一性。
+- `input.origin`:
+ - `user`: 常规用户输入，`parts` 通常是一个或多个 `{"type":"text"}`。
+ - `tool_response`: 当第三方执行完一个工具后向模型返回结果时使用。此时 `parts` 应包含 `{"type":"function_response","function_response":{...}}`，同时需要提供 `tool_call_id` 字段（见下方）。
+ - `system`: CLI 内部控制消息，例如 slash 命令恢复历史；第三方仅在需要注入系统提示时使用。
+- `input.parts`: 允许出现 `text`、`function_response`、`file_data` 等 `@google/genai` 支持的结构，CLI 会直接传给 `GeminiChat`。当 `origin="user"` 时，CLI 会将所有 text part 按顺序拼接成字符串后复用原有 TUI 语义（同 `prepareQueryForGemini` 流程）。
+- `options`：对单次请求的参数覆写（模型、采样、工具限制等），默认读取当前 Config。
+- 额外字段：
+ - `tool_call_id`: 当 `origin=tool_response` 时必填，用于与输出中的 `tool_call_id` 匹配（参照 `CoreToolScheduler`）。
+ - `continuation`: 布尔值，等价于 `submitQuery(..., { isContinuation: true })`；缺省由 CLI 根据 `origin` 判定。
+ - `tool_request`: 可选对象，镜像 `ToolCallRequestInfo` 中的 `args` / `isClientInitiated` / `prompt_id` 等字段，便于第三方在 CLI 侧复用同一调度逻辑（例如并发工具、子代理）。未提供时由 CLI 自动推断。
+
+#### 会话控制
+
+- `session_id` 不存在或传入 `"_new"` 时，CLI 自动创建新会话并返回首个响应中附带的实际 `session_id`。
+- 通过 `input.origin="system"` + `parts:[{"type":"instruction","text":"/clear"}]` 可触发清空历史（模拟 `/clear` 命令）。
+- `prompt_id` 与 `tool_call_id` 共同保证并发调用不串扰：`CoreToolScheduler` 与子代理均使用 `callId` 区分任务，第三方在发送工具结果时需保留该 ID。
+
+#### 命令与 @ 引用
+
+TUI 在文本模式下会根据输入字符串自动解析 slash 命令与 `@` 引用：
+
+- Slash (`/` 或 `?`) 由 `useSlashCommandProcessor` 处理，可触发内建命令、子命令及工具调度。
+- `@` 引用由 `handleAtCommand` 解析，会使用文件服务与 `read_many_files`、`glob` 等工具扩展用户提示。
+
+结构化协议保留同样语义：
+
+1. **隐式模式**：当 `origin="user"` 且首个 text part 以 `/` 或 `?` 开头时，CLI 自动进入 slash 流程；当文本包含未转义的 `@` 时，会调用 `handleAtCommand` 读取文件并在发送给模型前生成新的 `parts`。
+2. **显式模式（推荐给第三方）**：在 `input.command` 中描述命令，避免 CLI 解析字符串。
+ ```jsonc
+ {
+ "session_id": "session-123",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": "/chat list"}],
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ }
+ }
+ }
+ ```
+ - `kind`: `slash` | `at`.
+ - `path`: 对于 slash 命令，是命令层级数组（等价于 `commandPath`）；对于 `at`，则省略。
+ - `args`: 剩余参数字符串。
+ - `references`: 当 `kind="at"` 时可选，提前给出解析后的 `[{original:"@foo", resolved:"./src/foo.ts"}]`；若省略，CLI 将按隐式模式解析。
+
+示例：显式引用文件
+```jsonc
+{
+ "session_id": "session-123",
+ "input": {
+ "origin": "user",
+ "parts": [{"type": "text", "text": "请审阅 @src/main.py"}],
+ "command": {
+ "kind": "at",
+ "references": [
+ {"original": "@src/main.py", "resolved": "src/main.py"}
+ ]
+ }
+ }
+}
+```
+
+#### SDK 侧命令协作
+
+`useSlashCommandProcessor` 的执行结果可能包含多种动作（消息、弹窗、工具、提交 prompt、加载历史、退出等）。结构化模式通过 `action` 下发这些意图，SDK 需在本地处理效果，并在必要时再向 CLI 发送补充请求：
+
+| `command.result.type` | 说明 | SDK 动作建议 |
+|-----------------------|------|--------------|
+| `handled` | 已在 CLI 内部完成 | 无需处理 |
+| `message` | 返回信息/错误 | 在 UI 显示通知 |
+| `dialog` (`auth`/`theme`/`editor`/`privacy`/`settings`/`model`/`subagent_create`/`subagent_list`/`help`) | 需要弹窗或页面跳转 | 在第三方界面发起对应 UI |
+| `tool` | 触发工具调用 | 将 `tool_request` 或命令参数转为工具请求，向 CLI 发送并监听结果 |
+| `submit_prompt` | 立即向模型发送 PartListUnion | 将 `content` 作为下一条 `input.parts` 提交，并设置 `continuation=true` |
+| `load_history` | 重置会话历史 | 调用 CLI 提供的历史设置接口或重新加载 UI 历史 |
+| `quit` / `quit_confirmation` | 退出应用或询问确认 | 第三方控制自身生命周期，必要时触发 CLI 退出流程 |
+| `confirm_shell_commands` | 需要用户确认 shell 命令 | 弹窗确认；批准后携带 `approvedCommands` / `confirmationOutcome` 再次调用命令 |
+| `confirm_action` | 需要确认提示 | 同上，提供确认按钮并返回结果 |
+
+SDK 应暴露统一的命令执行 API，将用户输入映射为上述 `command`（显式或隐式），处理 `action`，并在必要时再次与 CLI 协调，确保行为与 TUI 一致。
+
+CLI 会使用提供的 `resolved` 值读取文件；若未提供则回退到 `handleAtCommand` 的自动解析逻辑。
+
+#### STDIN 命令回执
+
+- 当 `--input-format = stream-json` 时，CLI 必须对 STDIN 中的 `/`、`?`、`@` 等命令指令保持即时反馈，与文本模式一致。解析逻辑沿用 `useSlashCommandProcessor` 与 `handleAtCommand`，不会因结构化模式而绕过。
+- 命令解析完成后，CLI 需向 STDOUT 写出结构化响应，形如：
+ ```jsonc
+ {
+ "type": "result/command",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "command": {
+ "kind": "slash",
+ "path": ["chat", "list"],
+ "args": ""
+ },
+ "result": {
+ "type": "message",
+ "level": "info",
+ "content": "当前会话共有 3 条历史记录"
+ }
+ }
+ ```
+ 其中 `result` 字段遵循上表的 `command.result.type` 枚举（`message`、`dialog`、`tool`、`submit_prompt` 等），以便 SDK 在收到 `stream-json` / `stream-chunk-json` 消息后立即驱动 UI 或后续请求。
+- 若命令触发进一步的模型调用（例如 `/submit`、`@file` 展开），CLI 会在输出中继续串联对应的 `assistant`/`tool_call`/`result` 消息，保持与 TUI 相同的顺序与会话字段，使第三方可以纯文本输入 + JSON 输出的方式完整复现交互。
+
+#### 实时命令提示（Hint）
+
+- 结构化模式必须支持“字符触发提示”流程：当用户在第三方 UI 中输入 `/`、`@`、`?` 等触发字符但尚未按下回车时，集成方可立即发送 **Command Hint Request**，CLI 应返回对应提示数据而不写入会话历史。
+- Slash 请求示例（输入 `/c`）：
+ ```jsonc
+ {
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/c",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+ }
+ ```
+- Slash 响应示例（基于内置命令数据）：
+ ```jsonc
+ {
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {
+ "label": "chat",
+ "value": "chat",
+ "description": "Manage conversation history."
+ },
+ {
+ "label": "clear",
+ "value": "clear",
+ "description": "clear the screen and conversation history"
+ },
+ {
+ "label": "compress",
+ "value": "compress",
+ "description": "Compresses the context by replacing it with a summary."
+ },
+ {
+ "label": "copy",
+ "value": "copy",
+ "description": "Copy the last result or code snippet to clipboard"
+ },
+ {
+ "label": "corgi",
+ "value": "corgi",
+ "description": "Toggles corgi mode."
+ }
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+ }
+ ```
+- `@` 请求示例（输入 `@src/co`）：
+ ```jsonc
+ {
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "text": "@src/co",
+ "cursor": 7,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+ }
+ ```
+- `@` 响应示例（来自 `useAtCompletion` 文件搜索）：
+ ```jsonc
+ {
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "at",
+ "status": "ok",
+ "suggestions": [
+ {
+ "label": "src/components/",
+ "value": "src/components/"
+ },
+ {
+ "label": "src/components/Button.tsx",
+ "value": "src/components/Button.tsx"
+ },
+ {
+ "label": "src/components/Button with spaces.tsx",
+ "value": "src/components/Button\\ with\\ spaces.tsx"
+ }
+ ],
+ "metadata": {
+ "is_perfect_match": false
+ }
+ }
+ ```
+- `?` 请求示例（输入 `/?`，等价于 `/help`）：
+ ```jsonc
+ {
+ "type": "command_hint_request",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "text": "/?",
+ "cursor": 2,
+ "context": {
+ "cwd": "/workspace/demo",
+ "selected_text": ""
+ }
+ }
+ ```
+- `?` 响应示例（利用 `helpCommand` 的别名）：
+ ```jsonc
+ {
+ "type": "result/command_hint",
+ "session_id": "session-123",
+ "prompt_id": "session-123########preview",
+ "trigger": "slash",
+ "status": "ok",
+ "suggestions": [
+ {
+ "label": "help",
+ "value": "help",
+ "description": "for help on Qwen Code",
+ "matchedIndex": 0
+ }
+ ],
+ "metadata": {
+ "is_perfect_match": true
+ }
+ }
+ ```
+- `suggestions` 结构复用 TUI 中 `Suggestion` 定义，`status="loading"` 表示 CLI 仍在准备数据（例如 `useAtCompletion` 初始化文件索引），前端可据此展示 Loading；`error` 时附带 `message`。
+- CLI 内部复用 `useSlashCompletion`、`useAtCompletion` 等逻辑生成提示；该类请求不会调用 `GeminiChat` 或写入历史，`prompt_id` 可带 `_preview` 后缀并在响应中原样返回。
+- 支持连续触发：每当输入内容或光标位置变化时，集成方可重复发送 `command_hint_request`，CLI 需进行节流/去抖后反馈最新提示。若前端取消提示，可发送 `{ "type": "command_hint_cancel", "session_id": "...", "prompt_id": "...", "trigger": "slash" }` 通知 CLI 终止耗时搜索。
+
+#### 日志分层策略
+
+- CLI 仍通过 `ConsolePatcher` 拦截 `console.log`/`warn`/`error`，并在 `x-qwen-terminal` 注解中携带 `channel="stderr"`、`source="console"` 与 `console_level`。
+- 为方便第三方过滤，建议在结构化模式下扩展 `annotations[].log_scope` 字段（取值如 `system`、`tool`、`debug`），默认与 TUI 中 `ConfigLogger` 的级别组合保持一致（见 `packages/cli/src/config/config.ts`）。
+- 对于工具执行产生的日志，可继续经由 `ToolResultDisplay` 输出；若需要更细粒度过滤，可在对应 `result_display` 中附加 `log_scope`。
+
+#### 心跳与保活
+
+- 结构化协议提供与实时提示类似的独立事件，不污染会话上下文：
+ - 集成方可定期发送 `{"type":"heartbeat_request","session_id":"session-123"}`（可选携带 `prompt_id`）。
+- CLI 以 `{"type":"result/heartbeat","session_id":"session-123","status":"ok","ts":1739430123}` 回复；亦可在后台主动推送相同事件。
+- 若超过约定时间（例如 10 秒）未收到心跳响应，第三方可判定子进程已挂起并执行重启。
+- `@third-party/anthropics/claude-agent-sdk-python` 当前未实现心跳机制，需由本项目 CLI/SDK 自行补足；P1.1 实施时需定义默认间隔、超时策略及是否允许 SDK 自定义心跳频率。
+
+#### 实时中断（Escape 指令）
+
+- 结构化模式必须暴露与 TUI 相同的“终止当前响应”能力。TUI 通过 `useGeminiStream.ts` 中的 `useKeypress` 监听 ESC 键并调用 `cancelOngoingRequest`：该流程会中止 `AbortController`、记录 `ApiCancelEvent` 遥测、补齐 `pendingHistoryItem`，并向历史追加“Request cancelled.” 等提示。
+- 集成方可在任意时刻通过 STDIN 写入下述控制消息来触发相同行为：
+ ```jsonc
+ {
+ "type": "control/cancel",
+ "session_id": "session-123",
+ "prompt_id": "session-123########8",
+ "reason": "escape"
+ }
+ ```
+ - `session_id`: 必填，用于定位当前会话；
+ - `prompt_id`: 可选；若提供，CLI 仅当该 prompt 正在 `Responding`/`WaitingForConfirmation` 状态时才执行取消；缺省时默认取消最近一次启动的请求；
+ - `reason`: 预留枚举，当前固定为 `"escape"`，后续可扩展 `"keyboard_interrupt"`、`"timeout"` 等。
+- CLI 响应要求：
+ - 若存在可取消的流式请求，必须复用 `cancelOngoingRequest` 的逻辑：调用 `AbortController.abort()`、写入 `ApiCancelEvent`、冲刷 `pendingHistoryItem` 并重置补全状态。
+ - 立即向 STDOUT 输出 `{"type":"result/cancel","session_id":"session-123","prompt_id":"session-123########8","status":"ok","message":"Request cancelled."}`，便于第三方 UI 更新状态。
+ - 当底层流返回 `GeminiEventType.UserCancelled` 事件时，追加发送 `{"type":"x-qwen-session-event","event":"USER_CANCELLED","message":"User cancelled the request."}`，提示会话被中断。
+ - 若当前不存在可取消的请求，则响应 `{"type":"result/cancel","session_id":"session-123","status":"noop"}`，不再触发其它事件。
+- 双击 ESC 清空输入属于客户端自身的输入框逻辑；结构化模式下的集成方可在本地复用该交互，无需再向 CLI 发送额外消息。
+
+#### 双向控制通道
+
+- 代码现状：`third-party/qwen-code` 目前只支持单向输出（CLI → STDOUT），TUI 中的确认/对话框逻辑直接在进程内处理，缺少像 Claude Code 那样的 `control_request` / `control_response` hook。
+- 设计需求：为了让 SDK 集成具备与 TUI 等价的能力（命令确认、敏感操作授权、子代理调度等），协议需复用“独立事件 + STDIN 回写”模式，实现真正的双向通信。
+ - 当 CLI 需要外部输入时，输出 `{"type":"control_request","session_id":"session-123","request_id":"req-1","request":{"subtype":"confirm_shell_commands",...}}`。
+ - 支持 In-Process MCP Server 时，CLI 还需输出 `subtype: "mcp_message"`，实体内携带 JSON-RPC (`tools/list`、`tools/call`、`initialize` 等)；SDK 处理后在 `control_response` 中返回 `{"response":{"mcp_response":{...}}}`。
+ - 第三方应用处理后，通过 STDIN 写回 `{"type":"control_response","request_id":"req-1","response":{"subtype":"success","result":{"behavior":"approve"}}}`。
+ - 该事件不写入会话历史，保持与 `command_hint`、`heartbeat` 相同的旁路通道。
+- 场景覆盖：
+ - `/confirm_shell_commands`、`confirm_action`、`quit_confirmation` 等需要用户响应的命令。
+ - In-Process MCP Server 工具调用链路（`mcp_message` → `mcp_response`）。
+ - 工具权限审批（类似 `can_use_tool`）、计划执行或子代理调度需要外部确认的步骤。
+ - 未来扩展的弹窗、表单、身份验证流程。
+- 回退策略：在通道未启用时，CLI 应采用显式策略（例如自动拒绝危险操作、提示“在结构化模式下不可用”），并在 `result/command` 中返回明确错误，避免静默失败。
+- 后续工作：
+ 1. 在 RFC 中追加 `control_request`/`control_response` 的 JSON Schema（参考 Claude Code 实现）。
+ 2. 在 CLI 中抽象统一的控制消息分发层，使 TUI 与 CLI 复用同一逻辑。
+ 3. 在 SDK 中实现监听与响应，暴露钩子给上层 UI。
+
+#### 事件机制分类
+
+为便于第三方实现统一的事件路由与处理，本 RFC 将结构化 STDIN/STDOUT 消息归纳为三类：
+
+1. **结果事件 (`result/*`)**
+ - CLI → STDOUT 的单向通告，例如 `result/command`、`result/command_hint`、`result/heartbeat`、`result/cancel`、`x-qwen-session-event`。
+ - 承载命令输出、提示建议、心跳反馈、取消结果及会话状态更新，不要求 SDK 回执。
+ - 建议第三方根据 `type` 字段实现事件派发，确保不同 UI/服务都能统一处理。
+
+2. **请求事件 (`*request`)**
+ - 第三方 → STDIN 的前向指令，例如 `command_hint_request`、`heartbeat_request`、`control/cancel`。
+ - 用于触发 CLI 的即时响应：
+ - `command_hint_request` 获取 `/`、`@` 等提示建议；
+ - `heartbeat_request` 维持保活；
+ - `control/cancel` 终止当前响应。
+ - CLI 会以对应的 `result/*` 事件回复（如 `result/command_hint`、`result/heartbeat`、`result/cancel`）。
+
+3. **控制通道事件 (`control_request`/`control_response`)**
+ - CLI → STDOUT 输出 `control_request`，SDK/第三方需在 STDIN 写回匹配的 `control_response`；
+ - 用于需要回执的回调场景：工具授权 (`can_use_tool`)、Hook (`hook_callback`)、规划中的 MCP 调用 (`subtype: "mcp_message"`) 等；
+ - 每条 `control_request` 包含唯一 `request_id`，SDK 必须在合理超时内返回结果或错误，避免 CLI 阻塞。
+ - `control_request` 不写入会话历史，而通过控制层旁路处理，保持与 TUI 行为一致。
+
+以上三类事件通过统一的 JSON Lines 协议传输，可视作同一事件机制的不同子类。集成方在实现时应：
+
+- 按 `type` 或 `subtype` 进行分发，避免将 `control_request` 与一般 `result/*` 混淆；
+- 确保请求事件在 STDIN 写入后正确等待相应的 `result/*` 反馈；
+- 对控制通道事件实现健壮的回执与超时处理，以防 CLI 阻塞或进入不一致状态。
+
+### JSON Schema 与版本协商
+
+- 在 OpenAI `/chat/completions` 基础上精简为“增量输入”模型，保留 `model`、`tools` 等字段，并新增 `session_id`、`prompt_id`、`origin`、`tool_call_id` 等会话字段。
+- CLI 在首个 `chat.completion` 对象的 `metadata`（或 `system_fingerprint` 扩展段）中附带 `protocol_version`、`output_format`、`input_format`、`capabilities`（当支持 chunk 输出时应包含 `chat.completion.chunk` 能力位）。
+- SDK 若请求超出 CLI 能力（例如 `protocol_version=3`），CLI 将返回 `chat.completion` 对象，其中 `choices[0].finish_reason="error"` 并在 `usage` 或 `metadata.error` 中携带 `unsupported_protocol` 描述，同时以非零退出码终止。
+
+### 错误语义
+
+- **致命错误**: 输出 OpenAI 风格错误对象，并以非零退出码终止：
+ ```json
+ {
+ "error": {
+ "message": "invalid tool input",
+ "type": "invalid_request_error",
+ "param": "tools[0].function.arguments",
+ "code": "QWEN_INVALID_TOOL_ARGS"
+ }
+ }
+ ```
+- **可恢复错误 / 任务失败**: 返回 `chat.completion` 对象，`choices[0].finish_reason` 设为 `stop`（或 `tool_calls`）并在 `choices[0].message.content` / `metadata.error` 中说明失败原因，CLI 继续保持健康状态。
+- **控制协议异常**: 若工具授权、Hook 回调出错，CLI 通过 `chat.completion` 对象携带 `metadata.control_errors`，SDK 可据此决定是否重试或中断。
+
+## 安全与资源控制
+
+- CLI 在 `stream-json` 模式下仍遵循现有的 Approval/工具白名单逻辑。
+- 计划中的 `control_request`/`control_response` 通道将允许 SDK/第三方在敏感操作前进行审计；在实现之前，应默认拒绝需要授权的动作，或要求用户回退到 TUI 模式。
+- 支持在协议层扩展 `heartbeat`，若超时可触发进程回收，避免资源泄漏。
+
+## 可观测性与调试
+
+- 第三方后端服务/SDK 记录消息序列到审计日志，便于重放与问题定位。
+- 提供示例命令：
+
+ ```bash
+ echo '{"model":"qwen-coder","messages":[{"role":"user","content":"你好"}]}' \
+ | qwen --input-format stream-json --output-format stream-json
+
+ echo '{"model":"qwen-coder","messages":[{"role":"user","content":"逐字输出问候"}]}' \
+ | qwen --input-format stream-json --output-format stream-chunk-json
+ ```

+# RFC: Qwen-Code CLI 结构化输入输出规范（整理版）
+
+## 概览
+
+| 字段 | 详情 |
+| --- | --- |
+| 状态 | Draft |
+| 更新时间 | 2025-10-13 |
+| 作者 | x22x22 |
+| 追踪 | |
+| 范围 | CLI 层 `--input-format/--output-format` 结构化协议、事件语义、错误规范与落地计划 |
+
+- 目标是为第三方系统与多语言 Agent SDK 提供稳定、可编程的 IPC Stream JSON 能力。
+- 协议保持与 TUI 相同的行为，补齐 JSON Lines 输出、对称输入以及控制通道，回应社区关于 `--input-format/--output-format json/stream-json` 的诉求。
+- 文档聚焦 CLI 侧能力，不涵盖 SDK 内部设计。
+
+## 背景与场景
+
+### Issue 795 概述
+- 社区在 issue [#795](https://github.com/QwenLM/qwen-code/issues/795) 中请求为 CLI 增加 `--input-format/--output-format json/stream-json`，希望参考 Claude Code 的实现，提供可被程序稳定消费的结构化 IO。
+- RFC 旨在扩展 CLI，使其在保持 TUI 兼容的同时，为 SDK 与第三方后端提供对称的 JSON 协议与消息语义。
+
+### 集成方场景
+- **任务级串行处理**：SDK 逐条发送 prompt，同时在多个阶段接收 CLI 返回的数据并二次处理后再展示给最终用户。
+- **任务级流式直传**：SDK 逐条发送 prompt，CLI 的流式响应被直接转发给用户，保持实时可见性。
+- **指令提示与快捷符号**：第三方输入框中的 `/`、`@`、`?` 等触发行为需要与 TUI 完全一致，确保不同前端体验统一。
+- **前端终端模拟**：利用 xterm.js 等库复刻终端交互，输入区域与终端输出分离，但仍需消费 CLI 的完整终端语义。
+
+### 集成方式
+- 第三方程序依赖后续提供的多语言 `qwen-code-agent-sdk`。
+- SDK 通过子进程方式启动 `qwen code`，并以 STDIN/STDOUT 建立双向 IPC。
+- SDK 负责读取 CLI 的结构化输出，并完成错误处理与状态管理。
+- 第三方应用消费 SDK 的结果，在自身 UI 或后端逻辑中呈现。
+
+### 现状痛点
+- CLI 仅面向人工交互的纯文本 STDOUT，输出语义不稳定，难以被自动化消费。
+- 缺乏对称的结构化输入协议，无法驱动高级自动化与工具调度流程。
+
+## 目标与范围
+
+| 类型 | 内容 |
+| --- | --- |
+| 设计目标 | 可配置输出格式、JSON Lines 流式协议、对称结构化输入、通用 schema、面向 SDK 友好化 |
+| 非目标 | 描述 SDK 具体实现（另见 Agent 框架文档） |
+| 核心痛点 | 仅有人机交互 STDOUT、缺少结构化输入、无法驱动自动化流程 |
+| 场景示例 | SDK 分批发送 prompt 并处理多段响应；流式直传用户；`/`,`@`,`?` 指令与 TUI 对齐；xterm.js 前端分离输入与终端 |
+
+## 接口总览
+
+| 类别 | 关键项 | 说明 |
+| --- | --- | --- |
+| CLI 参数 | `--input-format`、`--output-format`、`--include-partial-messages` | SDK 默认固定 `--output-format stream-json`，在流式模式追加 `--input-format stream-json`；`--include-partial-messages` 可开启 Qwen-Code 式增量输出 |
+| 输出事件 | `user`、`assistant`、`system`、`result`、`stream_event`、`control_request`、`control_response`、`control_cancel_request` | 全部以 JSON Lines 逐行写入 STDOUT，字段对齐 Claude Code CLI |
+| 输入事件 | `user`、`control_request`、`control_response`、`control_cancel_request` | JSON 行写入 STDIN，对称驱动 CLI 行为，Envelope 与 Claude Python SDK 一致 |
+| 通道语义 | 会话事件、控制通道、流式事件 | 明确回执要求（默认 60s 超时），防止 CLI 阻塞 |
+| 协议扩展 | 握手元数据、版本协商、错误语义 | 参考 Claude `initialize`、`result`、错误对象结构 |
+
+- 通信仍使用标准输入输出，未引入额外套接字。
+- `text` 模式保留原行为，结构化模式提供稳定 schema 与可观测字段。
+
+## 输出格式语义
+
+| 格式 | 适用场景 | 行为概要 | 兼容性 |
+| --- | --- | --- | --- |
+| `text` | 手动调试兼容模式 | 输出原有 TUI 文本 | 仅 CLI 手动/降级模式使用 |
+| `stream-json` | Claude Code 样式 JSONL | 每行含 `type` 字段：`assistant`、`user`、`result`、`stream_event`、`control_*` 等 | 对齐 Claude Code CLI |
+| `stream-json` + `--include-partial-messages` | 增量消息 JSONL | 在标准事件外追加部分 `assistant` 内容与 `stream_event`，便于实时展示 | 对齐 Claude Code `include_partial_messages` |
+
+### 消费策略
+
+- **消息级 JSONL（`stream-json`）**：适合第三方后端或 CLI 包装器按阶段消费结果，与 Claude Agent SDK 默认行为一致。
+- **增量模式（`stream-json` + `--include-partial-messages`）**：面向 IDE/UI“边生成边展示”的实时场景，SDK 需监听 `stream_event` 中的 `content_block_delta` 与 `message_stop` 事件完成聚合。
+- **终端语义一致性**：Claude Code CLI 不提供独立的终端注解事件；stdout/stderr 相关内容会以文本或工具结果形式写入 `assistant` 消息，增量期间由 `content_block_delta` 输送文本片段，宿主若需还原 ANSI 可解析内容本身。
+
+### `stream-json` 示例
+
+```json
+{"type":"system","subtype":"init","session_id":"session-123","data":{"model":"qwen3-coder"}}
+{"type":"stream_event","uuid":"evt-1","session_id":"session-123","event":{"type":"message_start","index":0}}
+{"type":"stream_event","uuid":"evt-2","session_id":"session-123","event":{"type":"content_block_delta","index":0,"delta":{"type":"text_delta","text":"正在分析…"}}}
+{"type":"stream_event","uuid":"evt-3","session_id":"session-123","event":{"type":"message_stop","index":0}}
+{"type":"control_request","request_id":"req-tool-1","request":{"subtype":"can_use_tool","tool_name":"edit_file","input":{"path":"src/main.py","patch":"--- a/src/main.py\n+++ b/src/main.py\n@@\n-print('Hi')\n+print('Hello')"}}}
+{"type":"control_response","response":{"subtype":"success","request_id":"req-tool-1","response":{"behavior":"allow","message":"已授权","interrupt":false}}}
+{"type":"assistant","message":{"role":"assistant","model":"qwen3-coder","content":[{"type":"tool_result","tool_use_id":"toolu_1","content":[{"type":"text","text":"命令执行成功"}],"is_error":false}]}}
+{"type":"result","subtype":"session_summary","duration_ms":6021,"duration_api_ms":5870,"is_error":false,"num_turns":2,"session_id":"session-123","total_cost_usd":0.0021,"usage":{"input_tokens":820,"output_tokens":640}}
+```
+
+### 增量消息行为要点
+
+- Claude CLI 仅提供 `stream-json`，当启用 `--include-partial-messages` 时，会把 Anthropic RawMessageStreamEvent 原样封装为 `stream_event`，常见事件类型包括 `message_start`、`content_block_start`、`content_block_delta`、`content_block_stop` 与 `message_stop`。
+- `stream_event.event` 中的字段与 Claude SDK `StreamEvent` dataclass 一致：`index` 对应内容块序号，`delta.type` 可能是 `text_delta`、`thinking_delta` 或 `input_json_delta` 等，SDK 需自行聚合增量并在 `message_stop` 后完成收尾。
+- `assistant` 消息在同一回合内仍返回完整的 `content` 列表（文本、工具调用、思考块等），方便第三方在增量消费结束后复用统一结构。
+- `result` 消息提供 `usage`、`duration_ms`、`duration_api_ms`、`num_turns`、`session_id` 等统计字段，可直接映射到原 RFC `chat.completion` 的资源消耗语义。
+
+## 事件载荷与注解
+
+Claude CLI 的结构化输出由 `third-party/anthropics/claude-agent-sdk-python` 中的 `SubprocessCLITransport` 读取并交由 `message_parser` 解析为强类型对象。`assistant`、`user`、`system`、`result`、`stream_event` 与 `control_*` 事件共同覆盖对话内容、工具调度、统计汇总与控制协议。对应关系如下：
+
+| 类型 | 主要字段 | 用途 |
+| --- | --- | --- |
+| `assistant` 内容块 | `content[].type`、`content[].text`/`thinking`/`tool_use`/`tool_result` | 复刻 Claude CLI 的会话消息与工具调用流程 |
+| `stream_event` | `event.type`、`event.delta`、`event.index` | 原样承载 Anthropic RawMessageStreamEvent（`message_start`、`content_block_delta` 等）以便还原增量输出 |
+| `system` | `subtype`、`data` | 广播初始化信息（模型、可用工具、slash 命令、设置来源等）或后续状态通知 |
+| `control_request.*` | `request.subtype`、`request_id`、`request` | 工具审批、Hook 回调、MCP JSON-RPC 桥接 |
+| `result` | `subtype`、`duration_ms`、`num_turns`、`usage` | 汇总任务统计、错误信息与成本 |
+
+### `StreamEvent` 示例
+
+```json
+{
+ "type": "stream_event",
+ "uuid": "evt-delta-1",
+ "session_id": "session-123",
+ "event": {
+ "type": "content_block_delta",
+ "index": 0,
+ "delta": {
+ "type": "text_delta",
+ "text": "命令执行成功"
+ }
+ }
+}
+```
+
+- 常见事件类型：`message_start`（会话增量开始）、`content_block_start`（声明内容块类型）、`content_block_delta`（增量文本或思考内容）、`content_block_stop`、`message_stop`。
+- `delta.type` 会区分 `text_delta`、`thinking_delta`、`input_json_delta` 等，第三方需结合 `event.index` 与 `parent_tool_use_id` 聚合增量。
+- 未启用 `--include-partial-messages` 时不会输出 `stream_event`；所有输出仅由完整的 `assistant`/`result` 构成。
+
+### 工具结果展示
+
+```json
+{
+ "type": "assistant",
+ "message": {
+ "role": "assistant",
+ "model": "qwen3-coder",
+ "content": [
+ {
+ "type": "tool_result",
+ "tool_use_id": "toolu_1",
+ "is_error": false,
+ "content": [
+ {"type": "text", "text": "diff --git a/src/main.py b/src/main.py\n@@\n-print('Hi')\n+print('Hello')"}
+ ]
+ }
+ ]
+ }
+}
+```
+
+- `tool_use_id`：与前一条 `tool_use` 块配对，Claude SDK 会将其映射为 `ToolResultBlock`。
+- `content` 可以是字符串或内容块数组；当返回 diff、JSON 等结构化信息时，可拆成多个 `text`/`image` 块。
+- `is_error=true` 时表示工具执行失败，SDK 应展示错误提示或回退。
+
+### 思考与会话事件
+
+```json
+{
+ "type": "assistant",
+ "message": {
+ "role": "assistant",
+ "model": "qwen3-coder",
+ "content": [
+ {
+ "type": "thinking",
+ "thinking": "Analyzing repository layout…",
+ "signature": "sig-001"
+ }
+ ]
+ }
+}
+```
+
+- `thinking` 块展示 Claude 的内部推理，`signature` 可用于安全校验。
+
+### SystemMessage 示例
+
+```json
+{
+ "type": "system",
+ "subtype": "init",
+ "session_id": "session-123",
+ "data": {
+ "cwd": "/workspace/demo",
+ "model": "qwen3-coder",
+ "slash_commands": ["commit", "run"],
+ "tools": ["read", "write", "run_command"],
+ "setting_sources": ["user"],
+ "permission_mode": "manual"
+ }
+}
+```
+
+- `system` 消息常以 `subtype="init"` 开场，`data` 中包含工作目录、可用工具、可加载的 slash 命令、权限模式等元数据。
+- 后续系统提示可能使用其他 `subtype`（如 `status_update`、`warning`），结构同样承载在 `data` 字段内。
+
+## 输入格式
+
+| 模式 | 行为 | 说明 |
+| --- | --- | --- |
+| `text` | 保留原有 TUI 输入体验 | 仅适用于手动调试或降级模式，沿用 CLI 传统逐行解析 |
+| `stream-json` | Claude Envelope JSONL | 每行 JSON 传递 `user`、`assistant`、`result`、`control_*` 等事件，SDK 以流式方式驱动 CLI |
+
+### 用户消息 Envelope
+
+```jsonc
+{"type":"user","message":{"role":"user","content":[{"type":"text","text":"请修复 main.py 的 bug"}]},"parent_tool_use_id":null}
+```
+
+- `message.content` 可为字符串或 `ContentBlock` 数组；当内容包含工具回执时应为 `tool_result` 块。
+- `parent_tool_use_id` 允许在工具串联或子任务续写时保持上下文关联，Claude SDK 会基于该字段恢复父工具调用。
+- SDK 可通过 `options` 字段覆写一次性参数（模型、权限模式、是否包含部分消息等），格式与 `ClaudeAgentOptions` 保持一致。
+- 写入完成后可调用 `end_input()`（或关闭 stdin）提示 CLI 当前回合结束，`SubprocessCLITransport` 会向 CLI 发送 EOF。
+
+### 工具结果回传 Envelope
+
+```jsonc
+{"type":"user","message":{"role":"user","content":[{"type":"tool_result","tool_use_id":"toolu_1","content":[{"type":"text","text":"命令输出"}],"is_error":false}]}}
+```
+
+- 当 CLI 通过 `control_request.can_use_tool` 请求外部执行操作时，SDK 负责落地实际动作并将结果回写为 `tool_result` 块。
+- `is_error=true` 表示工具失败，CLI 将以 `assistant` 消息或 `result` 反馈错误并决定是否中断后续流程。
+- 允许在 `content` 中混合多种块（文本、富媒体、JSON），Claude SDK 会按 `ContentBlock` 定义解析。
+
+### 会话控制与初始化
+
+- Claude SDK 在建立流式会话时会先发送 `control_request.initialize`，CLI 以 `control_response.success` 回传，`response` 中通常包含：
+ - `commands`：CLI 支持的命令与子命令列表。
+ - `output_styles`/`output_style`：默认输出格式（通常为 `stream-json`）。
+ - `serverInfo`：CLI 侧标识、版本号、可选能力标志。
+- SDK 在构造初始化请求时会将 Hook 与 MCP 配置编码至 `request` 字段（如 `hooks`、`mcp`、`permission_mode`），字段结构与 `InitializeRequest` / `InitializeSuccessPayload` 对齐。【参考 `src/claude_agent_sdk/_internal/query.py`】
+- 初始化完成后，CLI 将继续输出 `assistant`/`stream_event`／`result` 等消息，保持与 TUI 一致的事件顺序。
+
+### SDK 主动控制请求
+
+- Claude SDK 通过 `_send_control_request()` 发送下列子类型：
+ - `interrupt`：请求 CLI 终止当前任务，常用于用户点击“Stop”。
+ - `set_permission_mode`：动态调整权限模式（如 `auto`、`manual`）。
+ - `set_model`：切换模型，允许传入 `null` 表示恢复 CLI 默认。
+ - `initialize`：首个握手请求，封装 Hook、权限、MCP 配置。
+- 每个请求包含唯一 `request_id`，SDK 会等待最长 60 秒的 `control_response` 回执，超时将抛出 `Control request timeout` 并清理挂起状态。
+
+### CLI 主动控制请求与取消
+
+- CLI 在需要外部确认或执行扩展逻辑时输出 `control_request`：
+ - `can_use_tool`：征询工具执行权限，可携带 `permission_suggestions`、`blocked_path` 等上下文。
+ - `hook_callback`：触发 SDK 侧自定义 Hook，并将返回值通过 `control_response` 回写。
+ - `mcp_message`：封装 JSON-RPC 报文与服务器名称，交由 SDK 托管的 MCP Server 处理。
+- 若需要放弃等待，CLI 会发送 `control_cancel_request`，SDK 应停止对对应 `request_id` 写回结果，避免状态错乱。
+
+## 实时事件
+
+| 能力 | 事件 / 请求 | 响应 | 说明 |
+| --- | --- | --- | --- |
+| 增量输出 | `stream_event.message_start` / `content_block_*` | `assistant` 消息或 `stream_event.message_stop` | 描述增量生成生命周期，便于还原逐 token / 块输出 |
+| 控制回执 | `control_request.*` | `control_response.success/error` | 工具审批、Hook/MCP 回调需严格配对 `request_id` |
+| 中断 | SDK 发送 `control_request.interrupt` | `control_response.success` + `result` | 停止当前任务并返回汇总信息 |
+| 取消提示 | `control_cancel_request` | 无需响应 | CLI 请求放弃等待某个控制回执，SDK 仅记录并清理挂起状态 |
+
+```jsonc
+{"type":"stream_event","uuid":"evt-2","session_id":"session-123","event":{"type":"message_stop","index":0}}
+```
+
+- SDK 应组合前序 `content_block_delta` 与此处的 `message_stop` 来生成最终文本。
+- Claude CLI 未提供额外的 `command_hint_request`、`heartbeat_request` 或 keepalive 事件，宿主应用需自行设定超时与保活策略。
+
+## 事件分类与通道
+
+| 类别 | 方向 | 代表事件 | 回执要求 | 作用 |
+| --- | --- | --- | --- | --- |
+| 会话主通道 | CLI → STDOUT | `user`（回放）、`assistant`、`result`、`system`、`stream_event` | 无需回执 | 呈现对话、工具输出、统计、保活 |
+| 控制通道 | CLI ↔ STDIO | `control_request` / `control_response` | 必须匹配 `request_id` | 工具审批、Hook、MCP、初始化、权限切换 |
+| 输入通道 | SDK/第三方 → STDIN | `user`、`control_request`（SDK 发起） | CLI 必须处理或返回错误 | 驱动用户输入、主动控制、取消 |
+
+- `system` 消息用于广播初始化能力，`result` 消息返回统计与错误信息，`stream_event` 则承载增量输出；三类事件共同覆盖主通道语义。
+- 所有事件均以 JSON Lines 传输，建议按照 `type`、`subtype` 与 `event.type` 路由，并为控制通道实现超时机制避免阻塞。
+
+## 控制请求与响应
+
+| 字段 | 说明 |
+| --- | --- |
+| `type` | 固定为 `control_request` 或 `control_response` |
+| `request_id` | 唯一标识，请求与响应配对 |
+| `request` | 当 `type=control_request` 时携带子类型与明细，例如 `can_use_tool`、`hook_callback`、`mcp_message` |
+| `response` | 当 `type=control_response` 时包含 `subtype`=`success`/`error` 及返回值 |
+
+- `control_request` 示例：
+
+```jsonc
+{
+ "type": "control_request",
+ "request_id": "req-1",
+ "request": {
+ "subtype": "can_use_tool",
+ "tool_name": "edit_file",
+ "input": {"path": "main.py", "patch": "..."},
+ "permission_suggestions": null
+ },
+ "session_id": "session-123"
+}
+```
+
+- 成功回执示例：
+
+```jsonc
+{
+ "type": "control_response",
+ "response": {
+ "subtype": "success",
+ "request_id": "req-1",
+ "response": {
+ "behavior": "allow",
+ "updatedInput": null,
+ "message": "允许执行"
+ }
+ }
+}
+```
+
+- 失败回执示例：
+
+```jsonc
+{
+ "type": "control_response",
+ "response": {
+ "subtype": "error",
+ "request_id": "req-1",
+ "error": "Tool execution denied by policy"
+ }
+}
+```
+
+- MCP 集成：当 `subtype="mcp_message"` 时，`request` 中包含 `server_name` 与 JSON-RPC `message`；SDK 需在 `response.response.mcp_response` 中回传规范化结果。【参考 `query.py` 及 `types.py`】
+- 若 CLI 发送 `control_cancel_request`，SDK 必须停止等待并记录取消原因。Claude SDK 当前仅记录日志，后续可扩展主动回执。
+
+## 版本协商与错误语义
+
+| 项目 | 说明 |
+| --- | --- |
+| 协议版本 | `control_response.success` (initialize) 可返回 `protocolVersion`、`supportedOutputStyles`、`capabilities`，SDK 应缓存用于兼容性判断 |
+| 版本不匹配 | 若 CLI 不支持请求的能力，会输出 `result`（`subtype="error"`、`is_error=true`）并在 stderr 打印 Anthropic 错误 JSON，SDK 侧会抛出异常终止流程 |
+| 致命错误 | CLI 遵循 Claude Code 错误对象格式（`type`、`message`、`code`），同时写入 `stderr`，SDK 将其包装为异常 |
+| 可恢复错误 | 可通过 `result` 或 `assistant` 返回错误消息，`is_error=true` 并保持进程健康 |
+| 控制协议错误 | `control_response.error` 的 `error` 字段提供文本描述，SDK 可决定重试、降级或中止 |
+
+致命错误示例：
+
+```json
+{
+ "error": {
+ "message": "invalid tool input",
+ "type": "invalid_request_error",
+ "param": "tools[0].function.arguments",
+ "code": "QWEN_CODE_INVALID_TOOL_ARGS"
+ }
+}
+```
+
+## 安全与资源控制
+
+| 领域 | 策略 |
+| --- | --- |
+| 权限 | 沿用 Claude CLI 审批模型；未收到 `control_response` 时默认拒绝高风险操作，并提示需要人工确认 |
+| 审计 | 建议记录完整 JSONL 流（含 `control_request`/`response`、`user` 输入），便于复盘与合规检查 |
+| 保活 | Claude CLI 未内置 keepalive 事件；建议结合 `stream_event` 活跃度与控制通道超时实现监控 |
+| 资源释放 | `SubprocessCLITransport.close()` 会在会话结束时清理子进程与异步任务组，第三方应在异常时调用 |
+
+## 日志分层与可观测
+
+| 组件 | 要点 |
+| --- | --- |
+| 会话输出 | `assistant` 文本块与 `stream_event` 增量共同覆盖 stdout/stderr，必要时可在内容中解析 ANSI |
+| `result` 统计 | `duration_ms`、`usage`、`total_cost_usd` 便于计费与性能分析 |
+| Hook/MCP 追踪 | `control_request`/`response` 可附带自定义元数据，建议记录以支持端到端追踪 |
+| OpenTelemetry | SDK/CLI 可分别注入 OTel Trace，将 `request_id` 和 `session_id` 作为 Span 属性以便串联 |
+
+- 推荐将所有消息持久化到审计日志，结合 `session_id`、`request_id`、`uuid` 实现重放与问题定位。
+
+## 调试示例
+
+```bash
+echo '{"type":"user","message":{"role":"user","content":[{"type":"text","text":"你好"}]}}' | qwen code --input-format stream-json --output-format stream-json --model qwen-coder
+
+echo '{"type":"user","message":{"role":"user","content":[{"type":"text","text":"逐字输出问候"}]}}' | qwen code --input-format stream-json --output-format stream-json --include-partial-messages
+```
+
+- 结合 `jq -c` 可验证事件流是否符合 Claude Envelope 约定。
+- 建议同时监控 CLI `stderr`，以捕获致命错误或协议不匹配提示。
+
+## 会话消息 Schema 摘要
+

+
+## 控制 Schema 摘要
+
+下表列出常见 `control_request` / `control_response` 子类型及关键字段，方便 SDK/第三方严格校验。
+
+| 子类型 | 方向 | 关键字段 | 说明 |
+| --- | --- | --- | --- |
+| `initialize` | SDK → CLI | `hooks`、`mcp`、`permission_mode` | 建立握手，公布 Hook、MCP 与权限配置 |
+| `interrupt` | SDK → CLI | - | 中断当前任务，CLI 返回 `control_response.success` 并输出 `result` |
+| `set_permission_mode` | SDK → CLI | `mode` | 切换 `auto`/`manual` 等权限模式 |
+| `set_model` | SDK → CLI | `model` | 动态切换模型，支持 `null` 恢复默认 |

+
+成功响应 (`control_response.success`) 常用 payload：
+
+- `InitializeSuccessPayload`：携带 `commands`、`output_style`、`serverInfo`、`capabilities`。
+- `ToolPermissionSuccessPayload`：`behavior`=`allow`/`deny`，可选 `updatedInput`、`updatedPermissions`、`message`。
+- `HookCallbackSuccessPayload`：`async`、`continue`、`decision`、`hookSpecificOutput` 等字段。
+- `McpMessageSuccessPayload`：封装 `mcp_response`，与 JSON-RPC 返回结构一致。
+- `AckOnlyPayload`：用于无附加数据的确认（如 `interrupt` 成功）。
+
+错误响应 (`control_response.error`) 在 `error` 字段提供字符串描述，可结合 `result` 或 `stream_event` 提示用户。
+
+## SDK ↔ CLI 协作流程速记
+
+1. **启动阶段**：`SubprocessCLITransport` 追加 `--output-format stream-json`、`--input-format stream-json`，合并环境变量并启动 `qwen` 进程，保持 STDIN/STDOUT 管道打开。
+2. **握手阶段**：SDK 发送 `control_request.initialize`，CLI 回以 `control_response.success`，并在后续输出首批 `assistant`/`system`/`result` 消息公布能力与状态。
+3. **主循环**：
+ - SDK 写入 `user` 消息或主动控制请求。
+ - CLI 输出 `assistant`、`stream_event`、`result` 等事件，并在需要授权时推送 `control_request`。
+ - SDK 匹配 `request_id` 写回 `control_response`，如有工具执行结果则以 `user` 消息的 `tool_result` 内容块反馈。
+4. **取消/中断**：SDK 可发送 `control_request.interrupt`，或由 CLI 输出 `control_cancel_request` 终止挂起请求；双方需清理本地状态并记录日志。
+5. **收尾阶段**：CLI 输出最终 `result`（`is_error`/`session_summary`），随后退出或等待下一轮输入；传输层在检测到 EOF 时释放子进程与缓冲队列。
+
+该流程在 Claude SDK 中由 `Query` 协程驱动，第三方实现可参考相同的状态机、超时与异常处理策略。
+
+## 源码索引（Claude 规范相关）
+
+| 功能 | 文件 | 说明 |
+| --- | --- | --- |
+| 传输层 | `src/claude_agent_sdk/_internal/transport/subprocess_cli.py` | 启动 CLI、处理 JSONL、维护进程生命周期 |
+| 控制与会话调度 | `src/claude_agent_sdk/_internal/query.py` | 握手、控制请求发送、输入流收尾、事件路由 |
+| 消息解析 | `src/claude_agent_sdk/_internal/message_parser.py` | 将 JSON 行解析为 `AssistantMessage`、`ResultMessage`、`StreamEvent` 等对象 |
+| 类型定义 | `src/claude_agent_sdk/types.py` | `ContentBlock`、控制请求/响应、结果统计等 TypedDict/Dataclass |
+| 对外客户端 | `src/claude_agent_sdk/client.py`、`query.py` | 暴露 `ClaudeSDKClient`、`query()` 等高层 API，封装命令行与选项 |
+
+- 建议在实现第三方 SDK 时直接参考以上模块，确保字段命名、结构与错误处理完全一致。
+- 若需自定义传输层（如 WebSocket），可沿用同样的 Envelope 与控制语义，实现最小改动的兼容适配。
+
+## 详细 Schema 附录
