The full rule list: 58 checks for Claude Code & MCP configuration. Open any one to see a real example of what fails, what passes, and how to fix it — then try it in the validator.
These are the 58 checks agentcheck runs on your config. The colored tag on each is that check's severity — not an error in your file. Click any check to see a real bad → good example and try it live.
