Developer research

Use firecrawl_developer_search through the Firecrawl MCP connection. If it is deferred, discover it with the host's tool search. Include the library, version, and exact error or symbol when known. Read the matched passages and source URLs. Developer searches are billed per request.

Distinguish official documentation from issues, proposals, and merged pull requests. A merged fix does not establish that it shipped in the user's version. Use firecrawl_scrape on a source URL when the passage lacks the needed context. Use firecrawl_search when the relevant source is outside the index or the index does not resolve the question.

Answer from the retrieved evidence, cite the relevant sources, and state any unverified version or release boundary. Respect the user's source and tool choices. Report connection or authentication errors.
