What problem does it solve? Developer questions are best answered from primary sources, but finding the exact issue, merged pull request, or documentation passage that defines a behavior is slow with general web search. This Skill queries the Firecrawl developer index to return matched passages from issues, PRs, READMEs, and docs so answers cite the authoritative source. ## Core Features & Use Cases - Passage-level search: Query the developer index over HTTP, MCP, or CLI and receive ranked results with matched markdown passages, preserving tables and code blocks. - Targeted filtering: Narrow results by artifact type (doc, issue, pull_request, readme), repository, documentation source, and repository metadata such as language, topic, and stars. - Question-type strategies: Match the search approach to the question, from literal error strings and known bugs to API contracts and version-specific behavior. - Use Case: When a library throws an unfamiliar error, search the error string scoped to issues and pull requests, then read the merged PR passages to learn exactly what changed and how to fix it. ## Quick Start Ask the agent to search the Firecrawl developer index for how a specific library handles a given error or API behavior and cite the source passage.
