 ### Code Structure
 - Always surround loop and conditional bodies with curly braces
 - Open curly braces always go on the same line as whatever necessitates them
+   - An open curly brace MUST be followed by a newline, with the body indented on the next line
 - Parenthesized constructs should have no surrounding whitespace
 - Single space follows commas, colons, and semicolons

 ### Type Management
 - Do not export `types` or `functions` unless you need to share it across multiple components
 - Do not introduce new `types` or `values` to the global namespace
+- Use proper types. Do not use `any` unless absolutely necessary.
+- Use `readonly` whenever possible.
+- Avoid casts in TypeScript unless absolutely necessary. If you get type errors after your changes, look up the types of the variables involved and set up a proper system of types and interfaces instead of adding type casts.
+- Do not use `any` or `unknown` as the type for variables, parameters, or return values unless absolutely necessary. If they need type annotations, they should have proper types or interfaces defined.

-Guidelines for writing unit tests using Vitest. These tests are `*.spec.ts`
+Please follow these guidelines when writing unit tests using Vitest. These tests are `*.spec.ts`
 
 ## Best Practices
 
-- Use proper mocks when possible rather than ad-hoc objects injected as dependencies. For example, call `createExtensionUnitTestingServices` to get some mock services, and `IInstantiationService` to create instances with those mocks.
-- If there is no preexisting implementation of a service that is appropriate to reuse in the test, then you can create a simple mock or stub implementation.
-- Avoid casting to `any` whenever possible.
-- When asked to write new tests, add tests for things that are interesting and nontrivial. Don't add a test that just verifies that a setter/getter work.
-- Prefer the runTests tool to run tests over a terminal command.
+- Prefer explicit Test/Mock classes over mutating real instances or creating adhoc one-off mocks.
+    - Never use `as any` to override private methods or assign properties on real objects.
+    - Mock versions of services are typically named `Mock*` or `Test*`, you can search to find whether one already exists.
+    - Some examples: `MockFileSystemService`, `MockChatResponseStream`, `TestTasksService`.
+
+- If there is no preexisting implementation of a service that is appropriate to reuse in the test, then you can create a simple mock or stub implementation in a file under a `test/` folder near the interface definition.
+    - A mock class should be configurable so that it can be shared and set up for different test scenarios.
+
+- The helper `createExtensionUnitTestingServices` returns a `TestingServiceCollection` preconfigured with some common mock services, use `IInstantiationService` to create instances with those mocks. Here's an example of using it properly
+
+```ts
+const serviceCollection = store.add(createExtensionUnitTestingServices());
+instantiationService = serviceCollection.createTestingAccessor().get(IInstantiationService);
+const mockFs = accessor.get(IFileSystemService) as MockFileSystemService;
+const testService = instantiationService.createInstance(SomeServiceToTest);
+```
+
+- When asked to write new tests, add tests to cover the behavior of the code under test, especially things that are interesting, unexpected, or edge cases.
+    - Avoid adding tests that simply repeat existing tests or cover trivial code paths.
+
+- If available, prefer the runTests tool to run tests over a terminal command.
+
+- Keep tests deterministic and fast.
+    - Avoid starting real servers or performing network I/O.
+
+- Avoid excessive repetition in tests, use `beforeEach` to set up common state.
+    - Use helper functions to encapsulate common test logic.
