Core Background & Industry Pain Points
Agents that Search/Scrape the web often stall without machine-readable next steps—empty results, same-origin URL clusters, 401 pages, and truncated PDFs need deterministic follow-ups, not fragile prompts.
Architecture Highlights & Internals
#4641 adds optional agent_hints: string[] on v2 Search/Scrape/Parse/Map when X-Firecrawl-Agent-Hints: true is set. #4786 publishes that preservation in firecrawl-py 4.45.0 and JS 4.42.0, plus Hangar browser/interact and onTermsRequired.
Authoritative Benchmarks & Measured Scores
No new first-party table ships with this SDK bump. Docs cite a third-party Agentic Search Benchmark Agent Score mean 14.58 (rank 2/8, n=100)—validate hint firing and MCP pin versions on your agents.
Developer Hands-on Guide
Upgrade with pip install -U firecrawl-py==4.45.0 or npm i @mendable/[email protected], enable the agent-hints header on agent/MCP paths, and bump MCP pins past 4.40.0. See Search docs.
