Context7

Fetch current documentation for any library or framework via the Context7 API. Use this instead of relying on potentially outdated training data.

Arguments

$ARGUMENTS

Parse the arguments as <library> <topic>. If only a library name is given, use a general query.

Workflow

Step 1: Resolve the library ID

curl -s ${CONTEXT7_API_KEY:+-H "x-api-key: $CONTEXT7_API_KEY"} "https://context7.com/api/v2/libs/search?libraryName=LIBRARY_NAME&query=TOPIC" | jq '.results[:3]'

Pick the best match. The id field is the library ID for step 2. If no results, try alternative names (e.g. "nextjs" vs "next.js").

Step 2: Fetch documentation

curl -s ${CONTEXT7_API_KEY:+-H "x-api-key: $CONTEXT7_API_KEY"} "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"

Summarize the relevant documentation. Include code examples where available.

Tips

• Works without an API key (rate-limited). Set CONTEXT7_API_KEY for higher limits
• Be specific with query to improve relevance
• URL-encode query parameters containing spaces (use + or %20)
• If the first result isn't right, check other results from the search
