    - **Location**: <file>:<line>
    - **SoT Reference**: <relevant SoT>
    - **Suggested Fix**: <recommendation>

    ## Coverage Gaps

    1. **Missing Happy Path**: <module> lacks complete flow test
    2. **Missing Permission Test**: <role> + <action> combination
    3. **Missing Error Code**: <code> not validated

    ## Recommendations

    1. [ ] Add test for <specific scenario>
    2. [ ] Increase coverage for <module>
    3. [ ] Update test to align with SoT v<new_version>

    ```
  </error_helpers>

<!-- ======================================================
     10. Safety Constraints
====================================================== -->
<safety_constraints>
  <sot_policy>
    **SoT Read-Only Policy (MANDATORY)**

    This skill operates in READ-ONLY mode for all SoT documents:
    - ✅ MAY read SoT documents for reference and validation
    - ✅ MAY generate test code that references SoT documents
    - ✅ MAY validate test results against SoT specifications
    - ❌ MUST NOT modify any files in docs/sot/*
    - ❌ MUST NOT propose changes to SoT documents
    - ❌ MUST NOT add/remove/rename SoT definitions

    If SoT inconsistencies are detected:
    1. Log the inconsistency with exact SoT reference
    2. Report to user for manual SoT governance process
    3. Continue test execution with current SoT values
  </sot_policy>

  <file_permissions>
    | Directory | Permission | Reason |
    |-----------|------------|--------|
    | docs/sot/* | READ-ONLY | SoT governance |
    | backend/services/* | READ-ONLY | Business logic immutable |
    | backend/api/* | READ-ONLY | API layer immutable |
    | backend/tests/* | READ-WRITE | Test code generation target |
    | collections/* | READ-WRITE | Newman collection output |
    | reports/* | READ-WRITE | Test report output |
  </file_permissions>

  <dry_run_mode>
    When dry_run=true:
    - Generate test code but do not write files
    - Show commands but do not execute
    - Preview report structure without data
  </dry_run_mode>
</safety_constraints>


<!-- ======================================================
     11. Usage Examples
====================================================== -->
<usage>
  Example 1: Generate L2 API tests for Daily Report module
  ```
  Use ai-ad-api-automation-test,
  mode = GENERATE,
  target_module = "daily_report",
  test_level = "L2".

  Generate complete test file following AUTOMATION_TEST_SPEC_v1.4.
  ```

  Example 1b: Generate L2 API tests for Ad Accounts module
  ```
  Use ai-ad-api-automation-test,
  mode = GENERATE,
  target_module = "ad_accounts",
  test_level = "L2".

  Generate complete test file for ad_accounts module.
  ```

  Example 1c: Generate L2 API tests for Suppliers module
  ```
  Use ai-ad-api-automation-test,
  mode = GENERATE,
  target_module = "suppliers",
  test_level = "L2".

  Generate complete test file for suppliers module.
  ```

  Example 2: Run all L2 API tests
  ```
  Use ai-ad-api-automation-test,
  mode = RUN,
  test_level = "L2",
  output_format = "cli".

  Execute pytest -m api and report results.
  ```

  Example 3: Execute Newman with Postman collection
  ```
  Use ai-ad-api-automation-test,
  mode = NEWMAN,
  collection_path = "collections/daily_report_api.json",
  environment_path = "environments/local.json",
  output_format = "html".

  Run Newman and generate HTML report.
  ```

  Example 4: Generate comprehensive test report
  ```
  Use ai-ad-api-automation-test,
  mode = REPORT,
  output_format = "html".

  Generate full report with coverage and SoT alignment.
  ```
</usage>


<!-- ======================================================
     11. Error Handling
====================================================== -->
<error_handling>
  Scenario 1: Target module not found
  - Report: "Error: Module '<name>' not found in backend/"
  - Suggest: List available modules from valid values enumeration
  - Action: Abort operation

  Scenario 2: SoT document not found
  - Report: "Warning: SoT document '<path>' not found"
  - Fallback: Continue with available SoT references
  - Action: Log warning, proceed with caution

  Scenario 3: Test execution fails
  - Report: Detailed error with stack trace
  - Include: Failed assertion details, SoT reference
  - Suggest: Potential fixes based on error type
  - Action: Mark test as FAILED, continue suite

  Scenario 4: Newman collection invalid
  - Report: "Error: Invalid Postman collection format"
  - Suggest: Validate JSON structure against Postman schema
  - Action: Abort Newman execution

  Scenario 5: Coverage below threshold
  - Report: "Warning: Coverage XX% below threshold YY%"
  - List: Uncovered modules/functions
  - Action: Mark build as FAILED if CI blocking

  Scenario 6: Output directory not writable
  - Report: "Error: Cannot write to '<output_dir>'"
  - Suggest: Check directory permissions, use alternative path
  - Action: Abort operation

  Scenario 7: File already exists (overwrite=false)
  - Report: "Warning: File '<path>' already exists"
  - Suggest: Set overwrite=true or use different output_dir
  - Action: Skip file, continue with next

  Scenario 8: Newman/Node.js not available
  - Report: "Error: Newman CLI not found"
  - Suggest: Run 'npm install -g newman newman-reporter-htmlextra'
  - Action: Abort NEWMAN mode

  Scenario 9: Execution timeout exceeded
  - Report: "Error: Test '<name>' exceeded timeout limit"
  - Include: Test level, configured timeout, actual duration
  - Action: Mark test as TIMEOUT, continue suite

  Scenario 10: Environment variables missing
  - Report: "Error: Required environment variable '<var>' not set"
  - Suggest: Check environments/*.json or set via shell
  - Action: Abort operation
</error_handling>
