Retrieves up-to-date documentation, API references, and code examples for libraries, frameworks, SDKs, CLI tools, and cloud services using Context7 CLI. Use for API syntax, configurations, migrations, setups, and debugging.
npx claudepluginhub dimagi/dimagi-claude-workflows --plugin context7This skill uses the workspace's default tool permissions.
Retrieve current documentation and code examples for any library using the Context7 CLI.
Fetches up-to-date library and framework docs via Context7 MCP tools (resolve-library-id, query-docs) for setup questions, API references, code examples, or named frameworks like React, Next.js, Prisma.
Fetches up-to-date documentation for libraries and frameworks like React, Next.js, Prisma, Supabase via Context7. Use for API references, setup questions, code examples.
Fetches up-to-date library/framework docs via Context7 MCP (resolve-library-id, query-docs) for setup questions, API references, code examples.
Share bugs, ideas, or general feedback.
Retrieve current documentation and code examples for any library using the Context7 CLI.
Make sure the CLI is up to date before running commands:
npm install -g ctx7@latest
Or run directly without installing:
npx ctx7@latest <command>
Two-step process: resolve the library name to an ID, then query docs with that ID.
# Step 1: Resolve library ID
ctx7 library <name> <query>
# Step 2: Query documentation
ctx7 docs <libraryId> <query>
You MUST call ctx7 library first to obtain a valid library ID UNLESS the user explicitly provides a library ID in the format /org/project or /org/project/version.
IMPORTANT: Do not run these commands more than 3 times per question. If you cannot find what you need after 3 attempts, use the best result you have.
Resolves a package/product name to a Context7-compatible library ID and returns matching libraries.
ctx7 library react "How to clean up useEffect with async operations"
ctx7 library nextjs "How to set up app router with middleware"
ctx7 library prisma "How to define one-to-many relations with cascade delete"
Always pass a query argument — it is required and directly affects result ranking. Use the user's intent to form the query, which helps disambiguate when multiple libraries share a similar name. Do not include any sensitive or confidential information such as API keys, passwords, credentials, personal data, or proprietary code in your query.
Each result includes:
/org/project)/org/project/version.If the user mentions a specific version, use a version-specific library ID:
# General (latest indexed)
ctx7 docs /vercel/next.js "How to set up app router"
# Version-specific
ctx7 docs /vercel/next.js/v14.3.0-canary.87 "How to set up app router"
The available versions are listed in the ctx7 library output. Use the closest match to what the user specified.
Retrieves up-to-date documentation and code examples for the resolved library.
ctx7 docs /facebook/react "How to clean up useEffect with async operations"
ctx7 docs /vercel/next.js "How to add authentication middleware to app router"
ctx7 docs /prisma/prisma "How to define one-to-many relations with cascade delete"
The query directly affects the quality of results. Be specific and include relevant details. Do not include any sensitive or confidential information such as API keys, passwords, credentials, personal data, or proprietary code in your query.
| Quality | Example |
|---|---|
| Good | "How to set up authentication with JWT in Express.js" |
| Good | "React useEffect cleanup function with async operations" |
| Bad | "auth" |
| Bad | "hooks" |
Use the user's full question as the query when possible, vague one-word queries return generic results.
The output contains two types of content: code snippets (titled, with language-tagged blocks) and info snippets (prose explanations with breadcrumb context).
--research if you weren't satisfiedIf the default ctx7 docs answer didn't satisfy, re-run the same command with --research before giving up or answering from training data. This retries using sandboxed agents that git-pull the actual source repos plus a live web search, then synthesizes a fresh answer. More costly than the default — use it as a targeted retry.
ctx7 docs /vercel/next.js "How does middleware matcher handle dynamic segments in v15?" --research
Works without authentication. For higher rate limits:
# Option A: environment variable
export CONTEXT7_API_KEY=your_key
# Option B: OAuth login
ctx7 login
If a command fails with a quota error ("Monthly quota reached" or "quota exceeded"):
ctx7 loginDo not silently fall back to training data — always tell the user why Context7 was not used.
