name	Context7 Usage
description	This skill should be used when the user asks to "check documentation", "latest API", "library docs", "context7", or needs up-to-date library documentation. Provides Context7 MCP usage patterns.
version	0.1.0

Provide patterns for effective use of Context7 MCP for retrieving up-to-date library documentation. Resolve package name to Context7-compatible library ID Library name to search for Must call before get-library-docs unless ID is known Returns list of matching libraries with IDs, trust scores, snippet counts Fetch documentation for a specific library Library ID from resolve-library-id Optional topic to focus on (e.g., "hooks", "routing") Max tokens to retrieve (default: 5000) Retrieve up-to-date documentation snippets with code examples Call resolve-library-id with library name resolve-library-id libraryName="react" Name similarity to query Trust score (7-10 preferred) Code snippet count (higher is better) Description relevance Call get-library-docs with selected ID get-library-docs context7CompatibleLibraryID="/facebook/react" topic="hooks" Common Context7-compatible library IDs for frequently used packages React: /facebook/react Next.js: /vercel/next.js TypeScript: /microsoft/typescript Node.js: /nodejs/node Express: /expressjs/express NixOS/nixpkgs: /nixos/nixpkgs Home Manager: /nix-community/home-manager Recommended token limits based on query type Quick lookup (specific API/function): 2000-3000 tokens Standard queries: 5000 tokens (default) Comprehensive topics: 8000-10000 tokens Use topic parameter to narrow documentation focus and reduce token usage For authentication-related documentation topic="authentication"

For React hooks documentation

topic="hooks"

For routing documentation

topic="routing"

Omit topic parameter for general overview and getting started documentation get-library-docs context7CompatibleLibraryID="/facebook/react" Use topic parameter with specific API names for focused reference documentation For specific React hook topic="useState"

For specific Next.js API

topic="getServerSideProps"

For specific TypeScript utility type

topic="Partial"

Verify codebase usage against latest documentation by combining Serena and Context7 1. Use Serena to find current library usage in codebase find_symbol name_path_pattern="useState"

2. Use Context7 to get latest documentation

get-library-docs context7CompatibleLibraryID="/facebook/react" topic="useState"

3. Compare current usage with documented best practices

Plan dependency updates with API migration by checking latest documentation 1. Use Context7 to check latest API changes get-library-docs context7CompatibleLibraryID="/vercel/next.js" topic="migration"

2. Use Serena to find all usages of changed APIs

find_referencing_symbols name_path="getStaticProps"

3. Plan migration based on documentation

Always resolve library ID before fetching documentation Prefer libraries with trust scores 7-10 for better documentation quality Use specific topics to reduce token usage and increase relevance Check snippet count as indicator of documentation completeness Use versioned IDs when available for specific version documentation Calling get-library-docs without resolving library ID first Always call resolve-library-id to get the correct Context7-compatible library ID Requesting maximum tokens for simple queries Use specific topics and appropriate token limits (2000-3000 for quick lookups, 5000 for standard queries) Using libraries with low trust scores or snippet counts Prefer libraries with trust scores 7-10 and higher snippet counts for better documentation quality Using incorrect or outdated library names (e.g., "react-query" vs "tanstack/query") Try alternative names or broader search terms if library not found Always resolve library ID before fetching documentation Verify trust score is 7 or higher before using library documentation Use specific topics to reduce token usage Check snippet count for documentation quality indicators Use versioned IDs when available for specific versions Combine with Serena for codebase verification workflows
