Score: 3.7/10 (Innovation: 4, Technical: 3, Documentation: 4, Utility: 4)

Check is a CLI tool that previews whether a command will succeed before execution by making an API call. It offers a simple 'runnable' or 'invalid' verdict, aiming to prevent failed commands in scripts and pipelines, but its utility is limited by per-use pricing and dependency on an external API.

Target audience: backend devs, devops
