Hey - I've left some high level feedback:

• Consider pinning anthropics/claude-code-action to a specific version or tag instead of @beta to avoid unexpected behavior changes from upstream updates.
• The claude-pr-review job currently has issues: write and id-token: write permissions; if the action doesn’t actually need these capabilities, tightening the permissions to the minimum required would reduce the workflow’s security surface.
