This skill enables retrieval of current documentation for software libraries and components by querying the Context7 API via curl. Use it instead of relying on potentially outdated training data.
To find the Context7 library ID, query the search endpoint:
curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY_NAME&query=TOPIC" | jq '.results[0]'Parameters:
libraryName (required): The library name to search for (e.g., "react", "nextjs", "fastapi", "axios")query (required): A description of the topic for relevance rankingResponse fields:
id: Library identifier for the context endpoint (e.g., /websites/react_dev_reference)title: Human-readable library namedescription: Brief description of the librarytotalSnippets: Number of documentation snippets availableTo retrieve documentation, use the library ID from step 1:
curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"Parameters:
libraryId (required): The library ID from search resultsquery (required): The specific topic to retrieve documentation fortype (optional): Response format - json (default) or txt (plain text, more readable)# Find React library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=react&query=hooks" | jq '.results[0].id'
# Returns: "/websites/react_dev_reference"
# Fetch useState documentation
curl -s "https://context7.com/api/v2/context?libraryId=/websites/react_dev_reference&query=useState&type=txt"# Find Next.js library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing" | jq '.results[0].id'
# Fetch app router documentation
