# comet guard

> Check open, design, build, verify, and archive requirements before advancing a Classic workflow.

`comet guard` is the stable phase-check command.

```bash theme={null}
comet guard <change-name> <phase>
comet guard <change-name> <phase> --apply
```

Without `--apply`, it reports readiness without changing state. With `--apply`, it advances through a legal transition only after every check passes.

| Phase   | Typical checks                                                              |
| ------- | --------------------------------------------------------------------------- |
| open    | Proposal, design, tasks, and delta specs are complete.                      |
| design  | The Design Doc and handoff evidence exist and point to the current change.  |
| build   | Required workflow choices, completed tasks, and build evidence are present. |
| verify  | Verification evidence and result are available.                             |
| archive | Verification passed and final confirmation is complete.                     |

`build_command` and `verify_command` are not valid `.comet.yaml` fields. Guard detects npm, Maven, or Cargo commands from project files. When it cannot infer an entrypoint, execute the real project command and record it with `comet state record-check`; guard validates the record instead of bypassing the check.

The packaged `comet-guard.mjs` launcher remains for compatibility, but normal use should prefer `comet guard`.
