tools-only Code review
Always start by inspecting the changes. If you're on the main git branch, typically the (staged) git diff. If you're on a different branch, the committed and uncommitted changes compared to the main branch.
Method
Please dispatch two subagents to carefully review the code changes. Tell them that they're competing with another agent. Make sure they look at both architecture and implementation. Tell them that whomever finds more issues wins honour and glory.
