Frameworks

Approved frameworks and libraries for this codebase with Context7 IDs for documentation lookup.

Critical Rules

1. Use ONLY approved frameworks - NEVER introduce alternatives or substitutes
2. Fetch docs when uncertain - Use Context7 MCP with the library ID directly
3. Use modern patterns - Avoid deprecated methods; check latest docs if uncertain

Fetching Documentation

When uncertain about API details, use Context7 MCP directly with the library ID:

mcp__context7__query-docs(libraryId="/pydantic/pydantic", query="field validators")
