What it does
Extract is an agent skill from athola/claude-night-market. Builds the gauntlet knowledge base from AST extraction and AI enrichment. Use when initializing or refreshing codebase knowledge for challenges.
Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering Knowledge bases. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.
When your agent uses it
- Refreshing codebase knowledge for challenges
- Tasks that involve Knowledge bases
Example prompts
- “Use the extract skill to build the gauntlet knowledge base from AST extraction and AI enrichment”
- “/extract”
Requirements
- Python 3
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Identify target directory: use the current working directory
- Run AST extraction: invoke the extractor script
- AI enrichment: for each extracted entry, enhance the detail
- Cross-reference: link related entries across modules by
- Merge with annotations: preserve existing curated entries
- Save: write to .gauntlet/knowledge.json
- Report: show summary by category, coverage gaps, difficulty
What it can do on your machine
Read from SKILL.md and the folder at commit 9f3eb00. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Extract loads about 510 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 222 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
Identify target directory: use the current working directory or a user-specified path
Run AST extraction: invoke the extractor script
bash python3 ${CLAUDE_PLUGIN_ROOT}/scripts/extractor.py <target-dir>AI enrichment: for each extracted entry, enhance the
detailfield with natural language explanation of business logic, data flow, architectural role, and rationaleCross-reference: link related entries across modules by matching imports, shared types, and data flow paths
Merge with annotations: preserve existing curated entries in
.gauntlet/annotations/Save: write to
.gauntlet/knowledge.jsonReport: show summary by category, coverage gaps, difficulty distribution
Exit Criteria
-
.gauntlet/knowledge.jsonexists and is valid JSON after the skill completes; entries from.gauntlet/annotations/are merged and not overwritten - Report shows entry counts broken down by all 7 categories (business_logic, architecture, data_flow, api_contract, pattern, dependency, error_handling) with coverage gaps identified
- Each extracted entry has a
detailfield containing a natural language explanation (not just the raw AST node name) - Cross-reference links between related entries are present for modules sharing imports, shared types, or data flow paths
Category Priority
- business_logic (weight 7)
- architecture (weight 6)
- data_flow (weight 5)
- api_contract (weight 4)
- pattern (weight 3)
- dependency (weight 2)
- error_handling (weight 1)
