Ota is an open-source CLI for repo readiness. It helps developers understand what a repo needs, why it is not ready, and how to make it runnable reliably. Most repos look complete until you actually try to use them. The real setup and runtime truth is usually scattered across READMEs, scripts, CI config, env files, and tribal knowledge. Ota surfaces what is missing, explains blockers, and helps bring it into a trustworthy, runnable state across local development, CI, and automation.
