ct-docs-lookup

ct-docs-lookup is a skill for Claude Code, Codex from kryptobaseddev/cleo. It costs 104 tokens per session (1,585 once invoked), scanned A, original, MIT.

A documentation lookup guide that retrieves current instructions and examples for software libraries and frameworks.

In plain words
What is it for?
Use it to find setup instructions, configuration details, API methods, and working examples for a named library or framework.
Why use it?
It reduces the risk of relying on outdated knowledge when configuring tools or writing code with libraries such as React, Express, or Prisma.

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

ct-docs-lookup 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 yesterday.

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 — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When the user asks about libraries, frameworks, or needs code examples, use Context7 to fetch current documentation instead of relying on training data.

When to Use This Skill

Activate this skill when the user:

  • Asks setup or configuration questions ("How do I configure Next.js middleware?")
  • Requests code involving libraries ("Write a Prisma query for...")
  • Needs API references ("What are the Supabase auth methods?")
  • Mentions specific frameworks (React, Vue, Svelte, Express, Tailwind, etc.)

How to Fetch Documentation

Step 1: Resolve the Library ID

Call resolve-library-id with:

  • libraryName: The library name extracted from the user's question
  • query: The user's full question (improves relevance ranking)

Step 2: Select the Best Match

From the resolution results, choose based on:

  • Exact or closest name match to what the user asked for
  • Higher benchmark scores indicate better documentation quality
  • If the user mentioned a version (e.g., "React 19"), prefer version-specific IDs

Step 3: Fetch the Documentation

Call query-docs with:

  • libraryId: The selected Context7 library ID (e.g., /vercel/next.js)
  • query: The user's specific question

Step 4: Use the Documentation

Incorporate the fetched documentation into your response:

  • Answer the user's question using current, accurate information
  • Include relevant code examples from the docs
  • Cite the library version when relevant

Guidelines

  • Be specific: Pass the user's full question as the query for better results
  • Version awareness: When users mention versions ("Next.js 15", "React 19"), use version-specific library IDs if available from the resolution step
  • Prefer official sources: When multiple matches exist, prefer official/primary packages over community forks

Why Context7 (not training data)

The user's global rule is explicit: prefer Context7 over training data for any library, framework, SDK, API, CLI tool, or cloud service — even well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. This includes API syntax, configuration, version migration, library-specific debugging, setup instructions, and CLI tool usage. Use even when you think you know the answer; training data may not reflect recent 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.
