The latest update to the GitNull CLI introduces gnull doctor, a built-in diagnostic and self-repair command designed to keep your local setup healthy and connected. It automatically inspects every layer of your CLI environment Node.js version compatibility, config file integrity, API URL validity, wallet configuration, skill.md structure, and live connectivity to
gitnull.xyz then reports exactly what is working and what needs attention.
Running a full health check takes seconds and gives you a clear, color-coded summary of your entire setup in one shot.
What makes gnull doctor more than just a diagnostic tool is its --fix flag.
Instead of hunting down config errors manually, you can run gnull doctor --fix and the CLI will automatically reset a missing or corrupt config file, restore a broken skill.md to a valid state, and correct a misconfigured API URL all without touching anything that is already working.
For teams and node operators running GitNull on a VPS, this means faster onboarding and less downtime when something goes wrong. The command also supports --json output for scripting and CI workflows, making it a first-class tool for both human operators and automated pipelines.
