Agent: I need to modify src/services/user.ts. Let me check the impact.

[Calls get_impact(file="src/services/user.ts", project_root="C:/path/to/project")]

Result:

Agent: What should I verify for this change?

Result:

Agent: What will this diff impact?

Agent: Which tests should I run?

[Calls get_relevant_tests(files=["src/services/user.ts"], project_root="C:/path/to/project")]

Agent: Run those tests.

Agent: Any contract updates needed?

## Required Workflow

### Step 1: Impact Analysis
Before implementing, use `get_impact` to identify all affected files.

### Step 2: Chain-Effect Checklist
Use `chain_effect_checklist` to get verification items for the file type.

### Step 3: Implementation
Make changes across all affected layers.

### Step 4: Build Verification
Use `verify_build` - task is NOT complete unless this returns success.

npm run dev    # Watch mode
npm run build  # Build once
npm start      # Run server
