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.json

3. 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
