name: context7 description: Look up current library documentation via Context7 MCP. Use when writing code that uses external libraries, frameworks, or packages to ensure correct API usage. compatibility: opencode metadata: workflow: documentation

What I do

• Query up-to-date documentation for any library or framework
• Resolve library identifiers for accurate documentation lookup
• Provide current API references and code examples
• Ensure correct usage of external dependencies

When to use me

Use this when working with external libraries, frameworks, or packages to ensure you're using the correct and current API syntax.

Workflow

1. Resolve library ID: Call context7_resolve-library-id with the library name and your query
2. Query documentation: Call context7_query-docs with the resolved library ID and specific question
3. Implement: Write code based on the retrieved documentation

When to Use

• External libraries (React, FastAPI, Prisma, Next.js, etc.)
• Frequently-updated packages where APIs may have changed
• Uncertain about API syntax or method signatures
• Any non-trivial import or library usage

Example

CopyUser: "Add NextAuth"

1. context7_resolve-library-id("nextauth", "how to set up authentication")
2. context7_query-docs(libraryId, "NextAuth setup and configuration")
3. Implement based on current docs

Critical Rules

• Never trust training data alone for library APIs
• Query docs BEFORE writing library code
• Use specific queries to get relevant documentation
• Limit to 3 calls per question - use best result if not found

Best Practices

1. Be specific: Use detailed queries for better documentation matches
2. Check versions: Library APIs change between versions
3. Verify examples: Cross-reference multiple code snippets when available
4. Cache knowledge: Reuse resolved library IDs within the same session
