When writing or changing a value in the file, also follow `yaml-conventions`. ## GITHUB_TOKEN Default Permissions Don't assume a repo's default `GITHUB_TOKEN` permissions — check them: ``` gh api repos/<owner>/<repo>/actions/permissions/workflow ``` Why: the read-only default ([since February 2023](https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github_token-permissions-to-read-only/)) applies only to repos created after that change, and it's a repo/org/enterprise setting (Settings → Actions → General → Workflow permissions) that anyone can flip. An older repo, or one where someone selected "Read and write permissions," defaults to read-write instead.
