Search GitHub for repositories matching a development intent and return structured EVIDENCE (not a verdict) for you to rank.

IMPORTANT — before calling this tool you MUST expand the user's single intent into 4-8 VARIED keyword queries: synonyms, likely library/package names, and problem restatements. Do not pass one raw phrase; keyword recall depends on the variety you supply. The server fires every query against GitHub's live search (README body included), dedupes, pre-ranks, and returns the strongest candidates each with a trimmed README excerpt + metadata. You then rank them and decide fork / study / avoid.

Example — intent "rate limiting middleware for express": queries: [ "express rate limit middleware", "express-rate-limit", "api throttling node", "request throttling express", "leaky bucket rate limiter node", "ddos protection express middleware" ]
