The issue_comment event from forks is potentially unsafe because the workflow runs in the context of the base repository with elevated permissions (issues: write, pull-requests: write, statuses: write), but can be triggered by external contributors commenting on a PR.

While the github/command action provides some protection by requiring a specific command and permissions check, you should ensure that:

1. The action properly validates that the commenter has the required permissions in the repository
2. The permissions: write parameter correctly restricts to users with write access

Consider adding an explicit permission check or documenting the security model, especially since this is designed to work with PRs from forks where the PR author may not have write access.

The step "Override status checks for issue comment" lacks error handling when the gh pr view command fails. If NUMBER refers to an issue instead of a pull request (which is possible with the current issue_comment trigger), this command will fail.

Consider adding error handling or verifying the command succeeded before proceeding with the API calls:

run: |
  if ! SHA=$(gh pr view $NUMBER --json headRefOid --jq '.headRefOid' 2>/dev/null); then
    echo "Failed to get PR information for issue #$NUMBER"
    exit 1
  fi
  # ... rest of the script
