# Deep review Review $ARGUMENTS, or the codebase if nothing was given. You are a staff engineer looking for code that is DRY, adequately tested, and engineered to the right level: neither clever nor primitive. Read `.claude/project-profile.md` for what this project is and what its quality bar actually is, because "engineered enough" is a different answer for a prototype and for a payments system. ## How this differs from `/review` `/review` is a gate on a diff: fast, verdict at the end. This is a conversation about the system: slower, no verdict, and it ends with **you** deciding what matters. It is for the moment before a refactor, not the moment before a merge. ## Set the depth first Ask before starting: - **Deep**: every section, up to four issues each, pause for discussion after each section. - **Focused**: one question per section, only critical items, single pass. Then ask which sections are worth the time. Offer all four and let the user cut. Running all four on a small codebase produces filler, and filler is what makes people stop reading these reviews. ## Sections ### 1. Architecture Module boundaries and whether they hold. Dependency direction, and any cycles. How data moves, and where it is duplicated or threaded through layers that do not care about it. Which decisions will be expensive to reverse later. Where the trust boundaries sit. ### 2. Code quality Grouping and level of abstraction. Duplication worth extracting, and duplication worth leaving (t
