Compute a maintenance/abandonment health verdict for a public GitHub repo from live GitHub data: a 0-100 score across commit recency, commit activity, issue/PR responsiveness, and release cadence, plus a verdict (actively maintained / slowing down / likely abandoned / archived) and human-readable reasoning. Free, unauthenticated MCP tool — the open twin of the paid x402-gated repo-health HTTP API (https://x402-repohealth-poc.theliminalguy.workers.dev/repo-health/:owner/:repo), same scoring logic, no payment required. Useful before depending on a library/tool: is this repo safe to build on? Uses GitHub's unauthenticated public REST API (60 requests/hour/IP) — for higher-volume or agent-automated x402-metered use, call the paid Worker endpoint instead.
