patterns-established:
  - "All processors inherit from BaseProcessor with STEP_NAME and async process() method"
  - "State recording on success/failure with summary info"

# Phase 04 Plan 03: AnalyzeProcessor Summary

**AnalyzeProcessor wrapping existing DeepAnalyzer for AI-powered content analysis, generating Markdown reports with YAML frontmatter**

## Performance

- **Duration:** 7 min
- **Started:** 2026-03-13T15:26:29Z
- **Completed:** 2026-03-13T15:33:00Z
- **Tasks:** 3
- **Files modified:** 4

## Accomplishments
- AnalyzeInput/AnalyzeOutput schemas with proper validation for analysis step
- AnalyzeProcessor correctly wrapping DeepAnalyzer for AI content analysis
- Markdown report generation with YAML frontmatter
- State recording on success and failure
- Module export from kb_pipeline.processors

## Task Commits

Each task was committed atomically:

1. **Task 1: Define Analyze Schemas** - `87d64b5`/`5164499` (test/feat)
2. **Task 2: Create AnalyzeProcessor with DeepAnalyzer integration** - `0b7d870` (feat)
3. **Task 3: Update processors __init__.py** - `029718e` (feat)

**Plan metadata:** pending (docs: complete plan)

_Note: TDD tasks may have multiple commits (test -> feat -> refactor)_

## Files Created/Modified
- `kb_pipeline/processors/analyze.py` - AnalyzeProcessor implementation wrapping DeepAnalyzer
- `kb_pipeline/processors/__init__.py` - Added AnalyzeProcessor to exports
- `kb_pipeline/schemas.py` - Added AnalyzeInput and AnalyzeOutput schemas
- `tests/test_processors/test_analyze.py` - Comprehensive tests (15 test cases)

## Decisions Made
- Use lazy import for DeepAnalyzer to avoid import errors when module not available
- Mock internal methods with patch.object instead of module-level imports for testing
- Article content types append original text to analysis output
- Analysis reports use YAML frontmatter generated by existing generate_frontmatter()

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- Test initially failed because patching kb_deep_analyzer.deep_analyzer.DeepAnalyzer requires the module to exist - resolved by using patch.object to mock internal _run_analysis method instead

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- AnalyzeProcessor provides AI-powered analysis for downstream pipeline orchestration
- Pipeline now has all processors: ParseProcessor -> DownloadProcessor -> ASRProcessor -> AnalyzeProcessor
- Ready for workflow orchestration (04-04) and end-to-end validation (04-05)
