What is Gauge CLI?
Gauge CLI is an open-source command line tool that helps developers improve how coding agents interact with their software. It runs real agent sessions against your skills, CLIs, SDKs, MCPs, or documentation to find where agents struggle. The tool captures common issues like interactive commands blocking automation, outdated API patterns, or unclear documentation.
You can run tests locally using Docker and your existing agent subscriptions or API keys. There is no separate account required. Gauge supports Claude Code, Codex, Pi, and OpenCode. It normalizes agent feedback so you can validate proposed fixes before releasing them. The setup requires Node.js version 22.13 or newer, npm, and Docker running Linux containers.
The workflow follows a hillclimbing approach: define tasks, run the agent, measure results, and repeat. You can save evaluation prompts and share test cases as Markdown files for continuous integration. All measurements and analysis data are stored locally in a private workspace.
