❌ Incorrect

{ "name": "CI", "description": "Template", "iconName": "workflow" }

✅ Correct

{
  "name": "CI",
  "description": "Template",
  "iconName": "workflow",
  "categories": ["JavaScript"],
  "filePatterns": ["package.json$"]
}

Additional examples

For larger repositories, this rule is often enabled together with one of the published presets so violations are caught in pull requests before workflow changes are merged.

ESLint flat config example

import githubActions from "eslint-plugin-github-actions-2";

export default [
  {
    files: ["**/*.{yml,yaml}"],
    plugins: {
      "github-actions": githubActions,
    },
    rules: {
      "github-actions/require-template-file-patterns": "error",
    },
  },
];
