# VALIDATION_FAILED

**What it means.** The request was malformed.

**What to do.** Check details.issues for the fields that failed validation and correct them.

- HTTP status: 400
- Retryable after applying the fix: yes

Every failure from the CLI or an MCP tool has this shape:

```json
{
  "ok": false,
  "code": "VALIDATION_FAILED",
  "message": "The request was malformed.",
  "fix": "Check details.issues for the fields that failed validation and correct them.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/VALIDATION_FAILED"
}
```

Apply `fix` (edit `file` when it is given), then run the same command again.
