Code Search (Exa)

Tool

Call the native MCP tool exa-code__get_code_context_exa directly. Parameters go in a JSON object.

Critical Rules

• Never run in main context. Spawn subagents or run sequentially.
• Always include the programming language in the query to reduce noise.
  • Good: "Go generics", "Python asyncio", "React 19 hooks"
  • Bad: "generics", "async", "hooks"
• Include framework + version when relevant: "Next.js 14", "Playwright Python".
• Include exact identifiers (function names, error messages) when you have them.
