Auto-Doc-Sync - Updates documentation when source code changes with GenAI complexity assessment.
Detects:
- New public functions/classes
- Changed function signatures
- Updated docstrings
- Breaking changes
Features:
- GenAI semantic complexity assessment (vs hardcoded thresholds)
- Smart decision on auto-fix vs doc-syncer invocation
- Reduces doc-syncer invocations by ~70%
- Graceful degradation with fallback heuristics
Actions:
- Simple updates: Auto-extract docstrings → docs/api/
- Complex updates: Invoke doc-syncer subagent
- Always: Update CHANGELOG.md
- Always: Update examples if needed
Hook Integration:
- Event: PostToolUse (after Write/Edit on src/ files)
- Trigger: Writing to src/**/*.py
- Action: Detect API changes and sync docs

│ The doc-syncer subagent can automatically: │
│ ✓ Extract docstrings from all new APIs │
│ ✓ Update docs/api/ with API documentation │
│ ✓ Update CHANGELOG.md with changes │
│ ✓ Update examples if needed │
│ ✓ Check for broken links │

🔴 BREAKING CHANGES:
{chr(10).join([f"{change.details}" for change in analysis.breaking_changes])}
To invoke doc-syncer subagent, tell Claude:
"Invoke doc-syncer subagent to update docs for {analysis.file_path.name}"
Or manually update docs:
→ Extract docstrings from new APIs
→ Update docs/api/{analysis.file_path.stem}.md
→ Update CHANGELOG.md with breaking changes
→ Update examples if API changed
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Documentation should always stay in sync with code!
