Farcaster Developer Signal Parser

This tool parses Farcaster feed data to identify developer opportunities, bounties, and related signals, returning them as a structured list of signals. It accepts two inputs: feed, a required string containing raw Farcaster text or JSON feed content, and keywords, an optional string of filter terms used to prioritize or narrow the extracted signals. The worker must analyze only the provided inputs and produce output that strictly validates against the system-provided structured output schema that is auto-produced by the platform for Farcaster developer opportunity and bounty signals, with no extra fields and with correct types and constraints.
