    steps:
      # Check out the repository
      - uses: actions/checkout@v2

      # Run Spectral
      - uses: stoplightio/spectral-action@latest
        with:
          file_glob: 'doc/api/*.yaml'

• file_glob: Pattern describing the set of files to lint. Defaults to *.oas.{json,yml,yaml}. (Note: Pattern syntax is documented in the fast-glob package documentation)
• spectral_ruleset: Custom ruleset to load in Spectral. When unspecified, will try to load the default .spectral.yaml ruleset if it exists.

Spectral Action will respect your Spectral Rulesets, which can be defined, extended, and overriden by placing .spectral.yml in the root of your repository.

However, if you'd like to simply use a core ruleset without additional configuration, create a .spectral.yml in you repository's root with only the contents: extends: ["spectral:{rulesetTagHere}"]
