Brings Go coverage analysis into your agent's edit loop so regressions surface before commit instead of after CI fails. Exposes three core MCP tools: check runs tests and enforces per-domain thresholds, suggest recommends coverage targets, and debt shows where gaps cost you most. Works locally over stdio with no external dependencies. The agent gets structured pass/fail signals with file-level details, catches drops in the same turn it ships code, and can re-run validation without waiting on your build pipeline. Built for polyglot projects but shines on standard Go layouts where test discovery just works.
