library-docs

library-docs is a skill for Claude Code, Codex from SawyerHood/sawyer-mart. It costs 84 tokens per session (451 once invoked), scanned A, original, MIT.

A research assistant for finding and reading the documentation and source code of software libraries and packages.

In plain words
What is it for?
Use it to understand an unfamiliar library’s API, locate its source repository, and investigate how its code works.
Why use it?
It helps answer library questions from the library’s actual repository instead of relying on incomplete or outdated guesses.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

library-docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Library Docs

Look up library documentation by finding and exploring the library's source code repository.

Workflow

1. Check for Local Availability

First, check if the library source code already exists locally:

# Check common locations
ls /tmp/cc-repos/{library-name} 2>/dev/null

If the library exists locally, skip to step 3.

2. Clone the Repository

If not available locally, find and clone the repository:

  1. Search for the library's GitHub repository (most libraries are on GitHub)
  2. Clone into the standard location:
mkdir -p /tmp/cc-repos
git clone https://github.com/{owner}/{repo}.git /tmp/cc-repos/{repo-name}

Common repository patterns:

  • npm packages: Check package.json homepage or repository field, or search https://github.com/{package-name}
  • Python packages: Check PyPI page for "Homepage" or "Source" links
  • Go packages: The import path often is the repository URL
  • Rust crates: Check crates.io for repository link

3. Research the Repository

Launch a Research agent (using the Task tool with subagent_type="Explore") to traverse the repository and answer the question.

Example prompt for the agent:

Explore the repository at /tmp/cc-repos/{repo-name} to answer: {user's question}

Focus on:
- README and documentation files
- Source code structure
- API exports and public interfaces
- Examples and tests for usage patterns

4. Synthesize and Answer

Use the research findings to provide a clear, accurate answer to the user's question about the library.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
