Claude Code Settings and Commands for Vibe Coding

A curated collection of Claude Code settings, custom commands and sub-agents designed for enhanced development workflows. This setup includes specialized commands and sub-agents for feature development (spec-driven workflow), code analysis, GitHub integration, and knowledge management.

For OpenAI Codex settings, configurations and custom prompts, please refer feiskyer/codex-settings.

Setup

# Backup original claude settings
mv ~/.claude ~/.claude.bak

# Clone the claude-code-settings
git clone https://github.com/feiskyer/claude-code-settings.git ~/.claude

# Install LiteLLM proxy
pip install -U 'litellm[proxy]'

# Start litellm proxy (which would listen on http://0.0.0.0:4000)
litellm -c ~/.claude/guidances/litellm_config.yaml

# For convenience, run litellm proxy in background with tmux
# tmux new-session -d -s copilot 'litellm -c guidances/litellm_config.yaml'

Once started, you'll see:

...
Please visit https://github.com/login/device and enter code XXXX-XXXX to authenticate.

Open the link, login and authenticate your Github Copilot account.

Note:

1. The default settings is leveraging LiteLLM Proxy Server as LLM Gateway to Github Copilot. You can also use copilot-api as the proxy as well (remember change your port to 4141).
2. Make sure the following models are available in your account; if not, replace them with your own model names:

• ANTHROPIC_DEFAULT_SONNET_MODEL: claude-sonnet-4.5
• ANTHROPIC_DEFAULT_OPUS_MODEL: claude-opus-4
• ANTHROPIC_DEFAULT_HAIKU_MODEL: gpt-5-mini

Commands

Github Spec Kit Workflow

Github Spec Kit - Unified interface for Spec-Driven Development.

To use it, run the following command to initialize your project:

uvx --from git+https://github.com/github/spec-kit.git specify init <project_name>

Alternatively, you can also copy .specify to your project root directory.

Available commands:

• /constitution - Create or update governing principles and development guidelines.
• /specify - Define requirements and user stories for the desired outcome.
• /clarify - Resolve underspecified areas (run before /plan unless explicitly skipped).
• /plan - Generate a technical implementation plan for the chosen stack.
• /tasks - Produce actionable task lists for implementation.
• /analyze - Check consistency and coverage after /tasks and before /implement.
• /implement - Execute all tasks to build the feature according to the plan.

Kiro Spec Workflow

Kiro Workflow - Complete feature development from spec to execution. The Kiro commands provide a structured workflow for feature development:

1. /kiro:spec [feature] - Create requirements and acceptance criteria
2. /kiro:design [feature] - Develop architecture and component design
3. /kiro:task [feature] - Generate implementation task lists
4. /kiro:execute [task] - Execute specific implementation tasks
5. /kiro:vibe [question] - Quick development assistance

Analysis & Reflection

• /think-harder [problem] - Enhanced analytical thinking
• /think-ultra [complex problem] - Ultra-comprehensive analysis
• /reflection - Analyze and improve Claude Code instructions
• /reflection-harder - Comprehensive session analysis and learning
• /eureka [breakthrough] - Document technical breakthroughs

GitHub Integration

• /gh:review-pr [PR_NUMBER] - Comprehensive PR review and comments
• /gh:fix-issue [issue-number] - Complete issue resolution workflow

Documentation & Knowledge

• /cc:create-command [name] [description] - Create new Claude Code commands

Settings

Sample Settings - Pre-configured settings for various model providers and setups.

Available Settings

copilot-settings.json

Using Claude Code with GitHub Copilot proxy. Points to localhost:4141 for the Anthropic API base URL.

litellm-settings.json

Using Claude Code with LiteLLM gateway. Points to localhost:4000 for the Anthropic API base URL.

deepseek-settings.json

Using Claude Code with DeepSeek v3.1 (via DeepSeek's official Anthropic-compatible API).

qwen-settings.json

Using Claude Code with Qwen models via Alibaba's DashScope API. Uses the Qwen3-Coder-Plus model through a claude-code-proxy.

siliconflow-settings.json

Using Claude Code with SiliconFlow API. Uses the Moonshot AI Kimi-K2-Instruct model.

vertex-settings.json

Using Claude Code with Google Cloud Vertex AI. Uses Claude Opus 4 model with Google Cloud project settings.

Limitations

WebSearch tool in Claude Code is an Anthropic specific tool and it is not available when you’re not using the official Anthropic API. Hence, if you need web search, you’d need to connect Claude Code with extertnal web search MCP servers, e.g. Tavily MCP, Brave MCP, Firecrawl MCP or DuckDuckGo Search MCP.

Use in VSCode Extension

For Claude Code 2.0+ extension in VSCode, if you’re not using Claude.ai subscription, please put the environment variables manually in your vscode settings.json:

{
  "claude-code.environmentVariables": [
    {
      "name": "ANTHROPIC_BASE_URL",
      "value": "http://localhost:4000"
    },
    {
      "name": "ANTHROPIC_AUTH_TOKEN",
      "value": "sk-dummy"
    },
    {
      "name": "ANTHROPIC_MODEL",
      "value": "opusplan"
    },
    {
      "name": "ANTHROPIC_DEFAULT_SONNET_MODEL",
      "value": "claude-sonnet-4.5"
    },
    {
      "name": "ANTHROPIC_DEFAULT_OPUS_MODEL",
      "value": "claude-opus-4"
    },
    {
      "name": "ANTHROPIC_DEFAULT_HAIKU_MODEL",
      "value": "gpt-5-mini"
    },
    {
      "name": "DISABLE_NON_ESSENTIAL_MODEL_CALLS",
      "value": "1"
    },
    {
      "name": "DISABLE_TELEMETRY",
      "value": "1"
    },
    {
      "name": "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC",
      "value": "1"
    }
  ]
}

Note that the contents of ~/.claude/config.json is also required to skip claude.ai login.
