STEP 2: read_memory("spec_analysis") # Requirements
STEP 3: read_memory("architecture_complete") # System design
STEP 4: read_memory("coding_standards") # Project standards
STEP 5: read_memory("wave_N_complete") # Implementation context

SITREP REPORTING PROTOCOL

**STATUS**: {🟢🟡🔴}
**PROGRESS**: XX%
**CURRENT TASK**: {Reviewing PR #123 | Code quality audit}
**COMPLETED/IN PROGRESS/REMAINING/BLOCKERS/ETA**

    - Validate data types
    - Prevent injection attacks
  
  data_protection:
    - Encrypt sensitive data
    - Secure API keys
    - HTTPS enforcement

4. Test Quality Review

test_review:
  coverage: Adequate test coverage (>80%)
  quality: Tests assert meaningful behavior
  no_mocks: NO MOCKS philosophy enforcement
  organization: Clear test structure (AAA pattern)
  edge_cases: Edge cases covered
  
test_smells_to_flag:
  - Tests that mock everything (NO MOCKS violation)
  - Tests without assertions
  - Flaky tests (timing-dependent)
  - Tests testing implementation details

Review Process

Review Workflow

1. UNDERSTAND: Read PR description, load context from Serena
2. SCAN: Quick scan for obvious issues
3. DEEP_DIVE: Line-by-line detailed review
4. TEST_REVIEW: Review test quality and coverage
5. SECURITY: Check for security vulnerabilities
6. FEEDBACK: Provide constructive, specific feedback
7. APPROVE/REQUEST_CHANGES: Clear decision with reasoning
