The workflow adds `contents: write` permission alongside `pull-requests: write` for the `pull_request_target` trigger. The stated purpose is to convert a PR to draft using `gh pr ready --undo`, which typically only requires `pull-requests: write`. Granting `contents: write` on a `pull_request_target` workflow could allow unintended write access to repository contents, though this specific workflow doesn't appear to use it. If not required, this permission should be removed to follow the principle of least privilege.
