  trunk-path:
    description:
      Path to Trunk Launcher. If not provided, we'll look for it the repo root, `.trunk/bin` and
      `tools/`. If it can't be found anywhere and is not provided explicitly, we'll download it on
      demand.
    required: false

  label:
    description:
      Label to append to the check run name (useful if running Trunk Check on multiple platforms)
    deprecationMessage: "Use `arguments: --github-label=value` instead."
    required: false

  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
      to 'populate_cache_only' in a dedicated workflow to populate the GitHub Actions cache with
      Trunk artifacts (see docs for more details).
    required: false

  check-all-mode:
    description:
      If set to "hold-the-line", computes new/existing issues by comparing to previous upload.
    required: false

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

  cache:
    description:
      Cache trunk downloads and results between runs. Caching is only needed when using ephemeral CI
      runners.
    required: false

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

    required: false

  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
      uploaded to the Trunk web app if this job is a scheduled job running on a branch, or if
      `check-mode` is set to 'all'.
    required: false

  upload-series:
    description:
      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
    default: auto

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

  setup-deps:
    description:
      Install dependencies for trunk check that the trunk CLI does not manage. This is only
