+#### Claude Code Plugin
+
+Install as a Claude Code plugin with intelligent Context7 integration:
+
+```sh
+claude
+/plugin marketplace add pleaseai/claude-code-plugins
+/plugin install context7@pleaseai
+```
+
+This provides a skill that Claude automatically activates when needed. Claude will intelligently use Context7 MCP tools when working with external libraries, frameworks, or when you need up-to-date documentation - without requiring explicit activation.
+
+The skill triggers automatically when you:
+- Write code using external libraries
+- Need library documentation or API references
+- Set up or configure frameworks
+- Request code examples with specific packages
+
+Optionally set your API key for higher rate limits:
+
+```sh
+export CONTEXT7_API_KEY="your-api-key"
+```

+description: Fetch up-to-date documentation and code examples for any library or framework using Context7. Use when writing code with external libraries, setting up tools, configuring frameworks, or needing current API documentation. Triggers on mentions of library names, npm packages, framework setup, API docs, or code generation requests.

+# Context7 - Library Documentation
+
+Always use Context7 MCP tools automatically when generating code, performing setup, or needing library documentation. **Do not wait for explicit user requests** - proactively fetch documentation when working with external libraries.
+
+## When to Use Context7
+
+Use Context7 automatically in these scenarios:
+
+- **Code Generation**: Writing code that uses external libraries or frameworks
+- **Setup & Configuration**: Setting up tools, libraries, or frameworks
+- **API Documentation**: Needing current API documentation for any library
+- **Best Practices**: Finding up-to-date examples and patterns
+
+## How to Use
+
+Follow this two-step process:
+
+### 1. Resolve Library ID
+```
+Use mcp__plugin_dev-tools_context7__resolve-library-id
+- Pass the library/package name
+- Returns Context7-compatible library ID
+```
+
+### 2. Fetch Documentation
+```
+Use mcp__plugin_dev-tools_context7__get-library-docs
+- Pass the library ID from step 1
+- Optionally specify a topic to focus on
+- Returns current documentation and examples
+```
+
+### 3. Apply Documentation
+Use the fetched documentation to provide accurate, up-to-date code and guidance.
+
+## Important Notes
+
+- Context7 works without an API key (with rate limits)
+- Set `CONTEXT7_API_KEY` environment variable for higher rate limits
+- Always fetch documentation before generating code with external libraries
+- Prefer Context7 over relying on training data for library-specific code
