Gauge - Open-source CLI for hillclimbing Agent Experience

Show HN: Gauge – Open-Source CLI to recursively improve your docs

Gauge is an open-source CLI that helps you make your Skills, CLIs, SDKs, MCPs, and docs easier for coding agents to discover and actually use. It runs real agents like Claude Code, Codex, Pi, and OpenCode against your product inside Docker, captures exactly where they get stuck, and lets your own coding agent test fixes before you publish them. The full evaluate-analyze-fix-retest loop runs locally with your existing agent subscriptions or API keys, and no Gauge account is required. Install it via npm, point it at your project, and start finding the friction that blocks agents.
