 ### Step 1: Understand the Scope
 - Determine if you are working on **Core Components** (`sdk-platform-java`) or a specific **Client Library** (`java-<service>`).
-- Review the root [AGENTS.md](../../AGENTS.md) for the Style Guide and Dependency Management rules that apply repo-wide.

 ### Step 2: Make Changes and Build
 - Apply your code changes.
-- To build efficiently, use the recommended flags or scoped builds detailed in [AGENTS.md](../../AGENTS.md#building-the-project).
+- To build efficiently, use the recommended flags or scoped builds detailed in [AGENTS.md](../../../AGENTS.md#building-the-project).
 
 ### Step 3: Determine and Run Tests
 - If working on a **Client Library**, run its unit tests (`mvn test` in the module directory) and check its README for integration test procedures.
 - If working on **Core Components** (`sdk-platform-java`), you **must** follow the testing heuristics in [sdk-platform-java/DEVELOPMENT.md](../../../sdk-platform-java/DEVELOPMENT.md#testing-guide) to know which tests are required.

 ### Step 4: Format Code
-- You **must** ensure the code is formatted before completing a task. Use the formatting commands listed in [AGENTS.md](../../AGENTS.md#code-formatting).

 ## 4. Testing Strategy
 - **Unit Tests**: `mvn test`.
 - **Integration Tests**: Module specific, may require emulators or live services.

 1. Minimize visibility scopes. Default to most restrictive access level.
 2. Use short names over fully qualified names.
