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, pull requests, READMEs, and docs so answers are grounded in the source that defines the behavior. ## Core Features & Use Cases - Ranked passage search: Query the developer index over HTTP, MCP, or CLI and receive matched markdown passages with artifact ids like issue:owner/repo#123. - 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-driven strategies: Match the query approach to the question type, 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, read the merged fix, and quote the passage that explains the resolution. ## Quick Start Ask the agent to search the Firecrawl developer index for what a specific library error means and cite the issue or pull request that resolved it.
