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

{
  "ok": false,
  "code": "BUILD_MISSING_DEPENDENCY",
  "message": "Build failed: a module the code imports is not in package.json.",
  "fix": "Add the missing module to dependencies in package.json, then re-run deploy.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/BUILD_MISSING_DEPENDENCY"
}

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