name: latest-docs description: | Fetch and verify latest official documentation before implementation. Use when implementing features with any library, framework, or technology. Prevents outdated patterns and deprecated API usage. metadata: context: implementation, development, library, framework, api auto-trigger: true

Latest Documentation Check

Purpose

Ensure implementations follow the latest official documentation. Prevent usage of deprecated APIs, outdated patterns, or breaking changes.

When to Use

Automatic Triggers

• Before implementing features using external libraries/frameworks
• Before using APIs that may have version-specific behavior
• When upgrading or migrating dependencies
• When user mentions specific library/framework versions

Manual Check

• When uncertain about current best practices
• When documentation may have changed since knowledge cutoff

Process

Step 1: Identify Technologies

List all technologies/libraries involved in the implementation:

• Framework (React, Vue, Next.js, etc.)
• Libraries (axios, lodash, etc.)
• Runtime (Node.js, Deno, Bun, etc.)
• Language features (TypeScript, Go, Python version)

Step 2: Fetch Latest Documentation

Use WebSearch to find current official documentation:

CopyWebSearch: "[library name] official documentation [current year]"
WebSearch: "[library name] latest version changelog"
WebSearch: "[library name] migration guide"

Step 3: Verify Version Compatibility

Check:

• Current stable version
• Breaking changes from previous versions
• Deprecated APIs to avoid
• New recommended patterns

Step 4: Document References

In your implementation response, include:

• Documentation URL referenced
• Version number verified
• Any deprecation warnings noted

Quick Reference

Important Reminders

1. Always verify version - Project may use different version than latest
2. Check package.json/go.mod - Confirm actual version in use
3. Note breaking changes - Inform user of any migration needs
4. Cite sources - Include documentation URLs in response

Output Format

When referencing documentation, include:

CopyDocumentation verified:
- [Library]: v[X.Y.Z] (https://...)
- Last checked: [date]
- Notes: [any deprecations or important changes]
