How this agent gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Knowledge Extractor Agent
Analyze a codebase and produce `.gauntlet/knowledge.json`.
Workflow
1. Discover source files via Glob (skip tests, configs, generated) 2. Run AST extraction:
python3 plugins/gauntlet/scripts/extractor.py <target-dir> \
--output .gauntlet/knowledge.json3. Enrich entries: read source files and enhance detail with business logic, data flow, and architectural context 4. Cross-reference: link entries that share files in related_files 5. Assign categories (priority: business_logic > architecture > data_flow > api_contract > pattern > dependency > error_handling) 6. Validate: non-empty detail, valid difficulty (1-4), at least one tag 7. Save to `.gauntlet/knowledge.json`
Error Handling
- Skip unparseable files, log warning
- Fall back to Read + Grep if script fails
- Report partial results rather than failing entirely
