SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developer questions about library behavior, error messages, and API contracts are best answered from primary sources, but finding the exact issue, merged pull request, or documentation passage manually is slow and unreliable.

Core Features & Use Cases

  • Primary-source search: Query a ranked index of issues, pull requests, READMEs, and docs that returns matched passages in markdown, preserving tables and code blocks.
  • Targeted filtering: Narrow results by artifact type, repository, documentation source, language, topic, stars, and more to sharpen queries.
  • Question-type strategies: Match the search approach to the question, whether it is a literal error string, an API contract question, a known bug, or an ecosystem-wide survey.
  • Use Case: You hit an obscure error string in a library. Search the exact message scoped to issues and pull requests, find the merged fix, and quote the passage that explains what changed.

Quick Start

Ask the agent to search the Firecrawl developer index for why a specific library throws your exact error message and cite the fixing pull request.

Frequently Asked Questions about firecrawl-developer-index

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I search GitHub issues and pull requests for an error message?▼

Search the literal error string plus the library name with types set to issue and pull_request. If nothing matches, strip volatile parts like paths, line numbers, and ids, then retry with the invariant middle of the message.

What is the Firecrawl developer index used for?▼

The developer index answers developer questions from primary sources: issues, merged pull requests, READMEs, and documentation pages. It returns ranked results with matched markdown passages, so you can quote the evidence and cite the URL directly.

Does the Firecrawl developer search API require an API key?▼

The developer search endpoint works keyless by default. Sending an Authorization header with a Bearer FIRECRAWL_API_KEY raises your rate limits but is not required to query the index.

Why does a repository filter return no documentation results?▼

Repository filters like language, topic, or min_stars only describe repositories, and most documentation pages have no repository behind them. Sending these filters without a sources scope restricts results to issues, pull requests, and READMEs by design.

When should I use a general web search instead of the developer index?▼

Use general web search for comparisons, opinions, news, outages, or projects with no indexed repository or docs. The index is for primary-source answers; trade-off discussions and unindexed projects are web questions.
