      files_yaml:
        description: |
          YAML string containing mappings of the form `{key}: [{glob1}, {glob2}, etc.]`.
          Where `{key}` is an arbitrary identifier for grouping a set of changed files
          (e.g. "test_cpp" for "if these files change, C++ tests should be re-run") and
          each `{glob}` is a glob expression matching file paths in the calling repo.
          For example, "re-run all C++ tests on any changes EXCEPT docs" might look like this:
          'test_cpp: ["**", "!docs/**"]'.
