+description: Use when user needs code generation, setup/configuration steps, or library/API documentation. Automatically fetch up-to-date docs for any library or framework without requiring "use context7" in the prompt.

+
+# Context7 Documentation Skill
+
+Automatically fetch up-to-date, version-specific documentation and code examples straight from the source.
+
+## Why Use This
+
+Without Context7:
+- Code examples based on outdated training data
+- Hallucinated APIs that don't exist
+- Generic answers for old package versions
+
+With Context7:
+- Current documentation from source repositories
+- Working code examples
+- Version-specific information
+
+## When to Trigger
+
+- User asks "how do I..." for any library
+- User needs code generation with a specific library
+- User asks about setup or configuration
+- User needs API reference or examples
+- User mentions any framework: React, Next.js, Vue, Svelte, Express, Prisma, Tailwind, etc.
+
+## Available Tools
+
+- `resolve-library-id`: Convert library name → Context7 ID
+- `get-library-docs`: Fetch docs with optional topic filter
+
+## How to Use
+
+1. Identify the library from user's question
+2. Call `resolve-library-id` with library name
+3. Call `get-library-docs` with resolved ID and topic (if specific)
+4. Present code examples and explanations
