Key point

The new command checks CLI version, login, project link, and configuration, reporting status and providing fix commands for each issue.

Vercel CLI now includes the vercel doctor command, which checks the setup and displays the specific command to fix each identified problem.
Checks cover CLI version and install, login status, current team, project link, and vercel.json configuration, also reporting active incidents from the Vercel status page.
Each check returns a status of OK, Warning, Failed, or Skipped; if vercel upgrade fails, the install check shows the CLI path and reinstall instructions.
The tool runs without login or a linked project and never prompts, allowing coding agents to execute it; the --json flag provides structured output of statuses and suggested commands.
