What this skill does
Firecrawl Developer Index Answer a developer question from the primary source: the issue where the bug was reported, the merged pull request that fixed it, the README or documentation page that states the contract. A blog post that describes a behaviour is a weaker answer than the passage that defines it, so reach for the index first and the open web second. There is no fixed recipe. Read the question, decide what kind it is, and choose the approach below. A literal error string wants a different move than "how do I do X". Don't run machinery a question doesn't call for. The tools, and what each is uniquely good at HTTP: GET POST https://api.firecrawl.dev/v2/search/developer MCP: firecrawldevelopersearch(query, k?, skills?) CLI: firecrawl developer <query> [--limit <n>] Ranked results over the whole index. Each carries id (issue:owner/repo#123), url, and the matched passages in markdown, so tables and code blocks survive. The artifact kind is the id prefix: doc:, issue:, pullrequest:, or readme:. The default first move for a developer question. It is the only surface that returns the passages, which is what lets you answer instead of pointing at a page. k / --limit is 1–100 and defaults to 10. skills="only" (HTTP/MCP only) restricts the search to agent-skill files. Keyless; send Authorization: Bearer $FIRECRAWLAPIKEY for higher rate limits. MCP: firecrawlsearch(query, categories: ["developer"]) CLI: firecrawl search <query> --categories developer Developer hits in a developer group beside web, each with url, title, description (the matched passage), position, and category: "developer" — web results carry no category, so that is the field to key on when merging. Use this when you are already running a web search and want developer sources weighed in the same call. It exposes none of the filters and no passage control. …
