ラベル関連の GitHub Actions

Work with Other Auto Label Actions

You need to provide a personal access token (with public_repo for a public repository, repo for a private repository) to an auto label GitHub Actions or GitHub Bot like actions/labeler.

Authenticating with the GITHUB_TOKEN - GitHub Docs

When you use the repository’s GITHUB_TOKEN to perform tasks on behalf of the GitHub Actions app, events triggered by the GITHUB_TOKEN will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository’s GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.
