Gauge CLI

Gauge CLI is an open-source CLI tool that tests and improves agent experience for coding products.

Gauge CLI is an open-source tool designed to help developers make their skills, CLIs, SDKs, MCPs, and documentation easier for coding agents to discover and use. The tool runs real coding agents against your product in local Docker containers, captures where they encounter friction, and lets your coding agent test fixes before publication. It supports Claude Code, Codex, Pi, and OpenCode, operating entirely locally using your existing agent subscriptions or API keys without requiring a Gauge account. The complete loop allows you to define tasks, measure outcomes, analyze structured transcripts, and validate improvements. Hosted Gauge is also available as a platform option for managed compute, automated analysis, and shared measurements.
