Library Research
Research and retrieve documentation for libraries, frameworks, and packages using Context7 integration.
When to use this skill
Use this skill when:
- •User asks about a library or framework
- •You need to research an API or package documentation
- •User mentions "How do I use..." for a third-party library
- •You need to find official documentation or examples
How It Works
This skill integrates with Context7 to efficiently retrieve library documentation:
- •Library Identification: Parse user query to identify library/package name
- •Resolution: Use Context7 to resolve library name to standard ID
- •Retrieval: Fetch comprehensive documentation for the library
- •Analysis: Extract relevant sections for user's specific question
- •Delivery: Present findings in clear, actionable format
Step-by-Step Process
1. Identify Library/Package
Parse the user's question to identify the library:
User: "How do I create a table with React?" Library: React Query: table component
2. Resolve Library ID
Use context7_resolve_library_id tool to get the official ID:
context7_resolve_library_id("react")
→ Returns: /facebook/react, /facebook/react/latest
3. Get Documentation
Use context7_get_library_docs to retrieve relevant documentation:
context7_get_library_docs("/facebook/react/latest", mode="code")
→ Returns: API reference, code examples, component guides
4. Extract Relevant Information
From the documentation, find:
- •Relevant classes/functions
- •Usage examples
- •Common patterns
- •Edge cases
- •Error handling
5. Present to User
Format findings as:
- •Brief explanation
- •Code example (if applicable)
- •Link to official docs
- •Related resources
Common Library Research Patterns
Pattern: "How to..." Questions
User: "How do I validate JSON with TypeScript?" Skill Response: 1. Identify: Zod, TypeScript, or JSON Schema 2. Get docs for selected library 3. Show validation example 4. Explain types and error handling
Pattern: Version-Specific Questions
User: "Does React 18 support X?" Process: 1. Resolve: /facebook/react/v18 2. Get mode-specific docs 3. Check API changes 4. Provide version notes
Pattern: Comparison Questions
User: "What's the difference between A and B libraries?" Process: 1. Research both libraries 2. Compare key features 3. Show usage differences 4. Recommend use cases
Tools & Integration
Context7 Tools
context7_resolve_library_id: Resolve library name to standard ID
- •Input: Library name string
- •Output: Standard library ID and alternatives
- •Use when: User mentions library but you need official ID
context7_get_library_docs: Fetch library documentation
- •Input: Library ID, mode (code/info)
- •Output: Documentation content, examples, references
- •Use when: You have library ID and need docs
webfetch: Retrieve external documentation
- •Input: Documentation URL
- •Output: Page content
- •Use when: Need latest docs or examples outside Context7
Safety & Best Practices
- •Read-Only: Never modify user code without explicit permission
- •Rate Limiting: Respect API limits on Context7 calls
- •Verification: Always verify documentation is current
- •Attribution: Link to official documentation sources
- •Error Handling: Clearly explain if library not found
Examples
Example 1: React Table Implementation
User: "How do I create a sortable table in React?" Process: 1. Resolve: /facebook/react 2. Get: Component examples, hooks, state management 3. Present: Table component pattern using useState 4. Show: Full working example with sorting logic 5. Link: Official React docs for tables and sorting
Example 2: TypeScript Generics
User: "How do TypeScript generics work?" Process: 1. Resolve: /microsoft/typescript 2. Get: Generic syntax, constraints, usage 3. Present: Generic function example 4. Explain: Type parameters and inference 5. Show: Common patterns and pitfalls
Example 3: Python Package Query
User: "What does the pandas groupby() method do?" Process: 1. Resolve: /pandas-dev/pandas 2. Get: groupby documentation and examples 3. Present: Method signature and parameters 4. Show: Practical groupby examples 5. Link: Official pandas groupby guide
Troubleshooting
Library Not Found
If Context7 can't find a library:
- •Try alternative names (npm vs PyPI names differ)
- •Search for official repository
- •Try webfetch with official docs URL
- •Inform user if library is very new/niche
Documentation Gaps
If official docs are incomplete:
- •Check GitHub repository for examples
- •Search for Stack Overflow answers
- •Look for blog posts or tutorials
- •Note limitations to user
Rate Limits
If hitting Context7 rate limits:
- •Cache previous queries
- •Batch multiple questions
- •Use less frequent calls
- •Fall back to webfetch
Best Practices
- •Always Link: Provide links to official documentation
- •Show Examples: Code examples are crucial for libraries
- •Verify Currency: Check documentation is up-to-date
- •Note Versions: Specify which library version you're documenting
- •Warn Changes: Alert users to breaking changes between versions
- •Test Examples: Where possible, verify code examples work
