Extract Codebase Knowledge

Build or rebuild the .gauntlet/knowledge.json knowledge base.

Steps

1. Identify target directory: use the current working directory

or a user-specified path

1. Run AST extraction: invoke the extractor script

```bash

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/extractor.py

```

1. AI enrichment: for each extracted entry, enhance the detail

field with natural language explanation of business logic, data

flow, architectural role, and rationale

1. Cross-reference: link related entries across modules by

matching imports, shared types, and data flow paths

1. Merge with annotations: preserve existing curated entries

in .gauntlet/annotations/

1. Save: write to .gauntlet/knowledge.json

1. Report: show summary by category, coverage gaps, difficulty

distribution
