name: tooling description: Tooling and verification. Apply when encountering unfamiliar third-party libraries, framework updates, uncertain parameter types, verifying best practices, or uncertain API parameters.

Tooling & Verification

Core Principle

"RTFM (Read The Fing Manual)." Don't guess API signatures. Don't assume library behavior. Before writing code, ensure you have evidence.

Official Documentation Verification

When encountering unfamiliar third-party libraries, framework updates, or uncertain parameter types:

1. Locate library ID: Use resolve-library-id to convert library name (e.g., "shadcn/ui", "stripe-js") to accurate system ID
2. Get documentation: Use get-library-docs to fetch latest official documentation snippets
3. Cite authority: Reference official documentation as basis for implementation in code comments or explanations

Applicable scenarios:

• "How do I use React 19's useActionState?"
• "What are the payment intent parameters for Stripe API?"

Real Code Search

Documentation tells you theoretically how to use it; GitHub tells you actually how to use it. When documentation is unclear or you need to reference best practices:

1. Search use cases: Use searchGitHub to search specific function or pattern implementations in real codebases
2. Pitfall guide: Observe if other developers have discussed related bugs in Issues
3. Pattern imitation: Look for implementation patterns in high-star projects as reference

Applicable scenarios:

• "Is this configuration option actually used in production?"
• "I want to see the actual implementation code for this complex pattern"

Execution Strategy

• Verify first, write second: Unless it's the most basic function in standard library, if there's any uncertainty, call tools
• No hallucination: If tools can't find it, clearly tell user "documentation not found" instead of fabricating a plausible API
