docs-seeker

docs-seeker is a skill for Claude Code, Codex from avibebuilder/claude-prime. It costs 116 tokens per session (1,223 once invoked), scanned A, original, MIT.

A documentation lookup tool for current references about libraries, frameworks, APIs, and online services. It retrieves official or otherwise preferred technical documentation instead of relying only on memory.

In plain words
What is it for?
Use it to verify API details, find required parameters, check library usage, and fetch feature-specific documentation before coding or troubleshooting.
Why use it?
Software documentation changes, so checking current references reduces errors in function signatures, required fields, and available features.

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

docs-seeker 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Why fetch instead of recall

Trained knowledge rots. Library APIs rename fields, deprecate hooks, restructure auth flows, and change defaults between minor versions. Answering from memory is how you get confidently wrong code. Replace memory with retrieval — cheaply, from sources designed for AI consumption.

The source hierarchy (and why)

Prefer sources in this order. The ranking is about signal per token, not just availability.

  1. llms.txt on the official docs site — hand-curated by the project, AI-optimized, token-dense, always current. This is the ideal source when it exists. Try {official-docs-url}/llms.txt first for any library with a docs site; many projects ship one even if they don't advertise it. If llms.txt is just an index of links, follow the most relevant ones. llms-full.txt exists on some sites and contains the full corpus — only reach for it when the user explicitly wants comprehensive docs, since it's large.

  2. Context7 — a mirror that ingests GitHub repos and exposes them at https://context7.com/{org}/{repo}/llms.txt, with optional ?topic={keyword} filtering. Use this when the project has no official llms.txt, or when you want to scope to one feature. The {org}/{repo} path mirrors GitHub exactly — derive it from the user's package.json, imports, lockfile, or the project's GitHub URL rather than guessing. For docs sites without a clear repo, Context7 also hosts https://context7.com/websites/{normalized-path}/llms.txt.

  3. GitMCP — any GitHub repo is accessible by swapping github.comgitmcp.io in the URL. Useful when Context7 doesn't have the repo indexed, or when you need source-of-truth README/examples straight from the repo.

  4. WebSearch — last resort. Slower, noisier, and you'll spend tokens filtering results. Only fall here when the three structured sources all miss. When you do search, query for "{library} llms.txt" first — it often surfaces an official or community-maintained one.

On any 404, timeout, or empty response: move to the next tier immediately. Never retry a failed source.

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.
