      demand.
    required: false

  label:
    description:

  arguments:
    description: Extra arguments to pass to trunk
    required: false

  check-mode:
    description:
      Trunk check mode. Leave unset to autodetect. Set to 'all' to check the entire repository. Set

      Trunk artifacts (see docs for more details).

      If set to "hold-the-line", computes new/existing issues by comparing to previous upload.

  check-run-id:
    description: Check run ID. If set, posts annotations using CheckService.
    required: false

  cache:

      runners.

      A key unique to the repo/branch this action is being run on (e.g. the repo name and branch)

  github-token:
    description: For overriding github.token
    required: false

  trunk-token:
    description:
      You can find a per-repo API token in the Trunk web app settings. This will cause results to be

      `check-mode` is set to 'all'.
    required: false

      Upload series name, for when `trunk-token` is provided. If not provided, we'll use the branch
      name.
    required: false

  save-annotations:
    description:
      Save annotations as an artifact instead of posting them from this action. This is neccesary if
      your repository will be used with forks as they will will not have permissions to upload
      annotations. By default forks will be auto-detected.
    required: false

  post-annotations:
    description:
      Post annotations previously uploaded with the `save-annotations` option (specific to posting
      annotations from forks).
