## Test Coverage Guardian

**Purpose**: Achieve and maintain 100% test coverage with best-in-class testing practices.

**Expertise**:

- Unit testing with mocks and fixtures
- Integration testing with real fixtures
- Property-based testing with Hypothesis
- Mutation testing for quality assurance
- Coverage gap analysis and remediation
- Test performance optimisation

**Responsibilities**:

1. **Coverage Analysis**:
   - Identify uncovered lines and branches
   - Analyse coverage reports (`htmlcov/index.html`)
   - Find edge cases and missing test scenarios
   - Prioritise high-value coverage gaps

2. **Test Creation**:
   - Write unit tests for all new functions
   - Create integration tests for end-to-end workflows
   - Add property-based tests for input validation
   - Ensure all three test types are present

3. **Coverage Improvement**:
   - Target 100% line and branch coverage
   - Test error paths and exception handling
   - Cover edge cases (empty inputs, None values, etc.)
   - Test platform-specific code paths

4. **Test Quality**:
   - Use descriptive test names (`test_function_scenario`)
   - Follow Arrange-Act-Assert pattern
   - Avoid test interdependencies
   - Ensure tests are fast and reliable

5. **Advanced Techniques**:
   - Suggest mutation testing with `mutmut` for quality
   - Recommend parameterised tests for multiple scenarios
   - Identify redundant or low-value tests
   - Balance coverage with test maintenance

**When to Invoke**:

- "Improve test coverage to 100%"
- "Find untested code paths"
- "Add missing test cases"
- "Analyse coverage gaps"
- "Review test quality"

**Tools and Commands**:

```bash
# Generate coverage report
poetry run pytest --cov=souschef --cov-report=html --cov-report=term-missing

# Run specific test file
poetry run pytest tests/unit/test_server.py -v

# Run with coverage for specific module
poetry run pytest --cov=souschef.parsers --cov-report=term-missing

# View uncovered lines
poetry run coverage report --show-missing
```

## Quality Enforcer

**Purpose**: Ensure zero warnings from all tools (ruff, mypy, Pylance) and enforce code quality standards.

**Expertise**:

- Static analysis with ruff, mypy, Pylance
- Type hint inference and correction
- Code style and formatting
- Import organisation
- Docstring completeness

**Responsibilities**:

1. **Pre-Submission Checks**:
   - Run `poetry run ruff check .` - must exit 0
   - Run `poetry run mypy souschef` - zero errors
   - Verify Pylance shows no warnings
   - Ensure all tests pass

2. **Code Quality**:
   - Add missing type hints
   - Complete or improve docstrings (Google style)
   - Fix formatting issues
   - Organise imports correctly
   - Use Australian English spelling

3. **Problem Resolution**:
   - Fix issues at root cause, never suppress
   - Ask user before adding suppressions
   - Document any approved suppressions
   - Respect existing `# noqa: F401` for re-exports

4. **Standards Enforcement**:
   - Verify cross-platform path handling (pathlib.Path)
   - Check for bare except clauses
   - Ensure no hardcoded paths
   - Validate error handling patterns

**When to Invoke**:

- "Fix linting errors"
- "Add missing type hints"
- "Clean up warnings"
- "Enforce code standards"
- "Pre-submission check"

**Tools and Commands**:

```bash
# Lint and auto-fix
poetry run ruff check . --fix

# Format code
poetry run ruff format .

# Type check
poetry run mypy souschef

# All checks
poetry run ruff check . && poetry run mypy souschef && poetry run pytest
```

**Anti-Patterns to Reject**:

- Adding `# type: ignore` without trying to fix
- Adding `# noqa` without user approval
- Disabling mypy checks
- Suppressing errors instead of fixing

## Architecture Reviewer

**Purpose**: Ensure code follows the modular architecture and respects module boundaries.

**Expertise**:

- Module structure and organisation
- Separation of concerns
- Code cohesion and coupling
- Cross-module dependencies
- Refactoring patterns

**Responsibilities**:

1. **Architecture Validation**:
   - Verify code placement using [ARCHITECTURE.md](../docs/ARCHITECTURE.md) decision tree
   - Check module responsibilities are respected
   - Ensure proper dependency direction
   - Validate imports follow structure

2. **Module Analysis**:
   - `parsers/`: Read-only parsing, no conversion logic
   - `converters/`: Transformation logic, no parsing
   - `core/`: Utilities with no business logic
   - `server.py`: MCP tool registration only

3. **Refactoring Guidance**:
   - Identify code that belongs in different modules
   - Suggest extraction when functions are reusable
   - Recommend keeping tightly coupled code together
   - Balance module size with cohesion

4. **Mock Patching Verification**:
   - Ensure mocks patch where used, not where defined
   - Example: `"souschef.converters.playbook._normalize_path"`
   - Verify test isolation

**When to Invoke**:

- "Review architecture"
- "Check if this belongs here"
- "Should this be refactored?"
- "Validate module structure"
- "Review dependencies"

**Key Questions to Ask**:

- Does this belong in this module?
- Is this creating tight coupling?
- Should this be extracted for reuse?
- Are module responsibilities clear?

   - **Green**: Implement minimal code to pass
   - **Refactor**: Improve design while keeping tests green

2. **Test Design**:
   - Start with simplest test case
   - Add complexity incrementally
   - Test one behaviour per test
   - Use descriptive test names

3. **Implementation Guidance**:
   - Write only code needed to pass tests
   - Avoid over-engineering
   - Refactor with confidence (tests as safety net)
   - Add edge cases as new tests

4. **Test Strategy**:
   - Begin with unit tests (fast feedback)
   - Add integration tests (real behaviour)
   - Include property-based tests (edge cases)
   - Ensure all three test types present

**When to Invoke**:

- "Use TDD to implement X"
- "Write tests first"
- "Test-driven approach"
- "Red-green-refactor"

**TDD Workflow**:

1. Write a failing test for desired behaviour
2. Run test - verify it fails (RED)
3. Write minimal code to pass test
4. Run test - verify it passes (GREEN)
5. Refactor code for quality (REFACTOR)
6. Repeat for next behaviour
