extract SKILL.md skillA
extract from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add athola/claude-night-market/extract@git:20260713.f98719bPins git:20260713.f98719b in mdr.lock. Pin the fingerprint instead.

Builds the gauntlet knowledge base from AST extraction and AI enrichment. Use when initializing or refreshing codebase knowledge for challenges.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Extract Codebase Knowledge
Build or rebuild the `.gauntlet/knowledge.json` knowledge base.
## When NOT To Use
- Tribal knowledge no parser can see (use `gauntlet:curate`)
- Building the code graph (use `gauntlet:graph-build`)
## Steps
1. **Identify target directory**: use the current working directory
or a user-specified path
2. **Run AST extraction**: invoke the extractor script
```bash
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/extractor.py <target-dir>
```
3. **AI enrichment**: for each extracted entry, enhance the `detail`
field with natural language explanation of business logic, data
flow, architectural role, and rationale
4. **Cross-reference**: link related entries across modules by
matching imports, shared types, and data flow paths
5. **Merge with annotations**: preserve existing curated entries
in `.gauntlet/annotations/`
6. **Save**: write to `.gauntlet/knowledge.json`
7. **Report**: show summary by category, coverage gaps, difficulty
distribution
## Exit Criteria
- [ ] `.gauntlet/knowledge.json` exists and is valid JSON after the
skill completes; entries from `.gauntlet/annotations/` are merged
and not overwritten

How to install
mdr add athola/claude-night-market/extract@sha256:825d76c7e0872533The line at the top of this page pins the label git:20260713.f98719b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
