+      "description": "Returns a single hash for the set of files that matches the `path` pattern. You can provide a single `path` pattern or multiple `path` patterns separated by commas. The `path` is relative to the `GITHUB_WORKSPACE` directory and can only include files inside of the `GITHUB_WORKSPACE`. This function calculates an individual SHA-256 hash for each matched file, and then uses those hashes to calculate a final SHA-256 hash for the set of files. If the `path` pattern does not match any files, this returns an empty string. For more information about SHA-256, see [SHA-2.](https://wikipedia.org/wiki/SHA-2)\n\nYou can use pattern matching characters to match file names. Pattern matching is case-insensitive on Windows.
