A tool for fetching current documentation and code examples for software libraries and frameworks through the Context7 service.

Looking up library identifiers and retrieving relevant documentation for implementation questions.

It reduces the risk of relying on outdated API details when you need to use a particular library.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.00493
Opus 5.5	$0.00023	$0.00197
Sonnet 5.5	$0.00011	$0.00099
Haiku 4.5	$0.00006	$0.00049

Security

Grade A, and why

context7 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 1mo 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

Context7 Documentation Fetcher

This skill fetches up-to-date documentation and code examples from libraries using the Context7 API.

Standard Workflow

Context7 requires a two-step process:

Step 1: Search for the Library ID

First, search for the library to get its ID:

GET https://context7.com/api/v2/libs/search?libraryName=<library>&query=<context>

Parameters:

libraryName: The library name (e.g., "react", "nextjs", "fastapi")
query: Search context to help find the right library

The response contains a results array with library objects. Use the id field from the first result.

Step 2: Get Documentation Context

Use the library ID to fetch relevant documentation:

GET https://context7.com/api/v2/context?libraryId=<id>&query=<question>

Parameters:

libraryId: The ID from step 1 (e.g., "/vercel/next.js")
query: Natural language question about the documentation

This returns ranked code snippets and documentation matching your query.

Example Usage

When the user asks about a library:

Search for the library: Fetch https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing Extract the library ID from the response (e.g., "/vercel/next.js")
Fetch documentation: Fetch https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=How to setup dynamic routes
Present the results to the user with the relevant code examples and documentation.

Tips for Best Results

Use specific, detailed queries rather than vague terms
Include relevant context in the query (e.g., "useState hook with TypeScript" instead of just "state")
The API works without an API key but has restricted rate limits

Files

What ships with it

46 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

Tools are how AI agents interact with the world. A well-designed tool is the difference between an agent that works and one that hallucinates, fails silently, or costs 10x more tokens than necessary. This skill covers tool design from schema to error handling.
