This dispatches a code reviewer subagent that gets clean context about your changes without your session history, keeping reviews focused on the actual work product. It's built for subagent-driven development where you review after each task, but works for any feature or bug fix. The reviewer gets git SHAs, requirements, and a description of what you implemented, then returns categorized feedback (Critical, Important, Minor). The templated approach means you can quickly get fresh eyes on code without context pollution. Works best when you actually fix the Critical and Important issues before proceeding rather than collecting feedback you'll ignore.
