PR description says Claude is invoked by mentioning @claude in a PR/issue comment, but this workflow also triggers on issues events (opened, assigned) and can run based on issue title/body contents. If that’s not intended, consider removing the issues trigger (or limiting it) to avoid unexpected runs and reduce attack surface.

The job runs whenever @claude is present, but there’s no check that the actor is trusted. Because this workflow uses a repository secret (CLAUDE_CODE_OAUTH_TOKEN), untrusted users (e.g., drive-by issue commenters / fork PR authors) could trigger it to burn API quota or exfiltrate context through the agent. Add an authorization guard to the if: (e.g., require author_association to be MEMBER|OWNER|COLLABORATOR, or validate the actor’s permission via the GitHub API) before running the action.
