What problem does it solve? Code that works can still be built wrong: over-abstracted, inconsistent with repository conventions, or carrying dead weight. This Skill performs a rigorous, design-first code review that judges structure and maintainability before hunting for bugs, so reviews produce evidence-backed findings instead of taste-based opinions. ## Core Features & Use Cases - Design-first review: Builds a counterfactual of the smallest credible shape before line-level review, so every structural finding names the concrete machinery it removes. - Six structured checks: Over-engineering, pattern drift, failure surface, naive edge cases, dead weight, and bugs, each with explicit scoping rules to avoid duplicated findings. - Confidence and cross-verification: Every finding gets a LOW/MEDIUM/HIGH confidence tag, with non-HIGH findings verified by a fresh subagent and empirical checks (tests, repros) where possible. - Use Case: After implementing a feature branch, ask for a review of the diff against the fork point; the Skill derives the target from git state, compares conventions against similar modules, and reports a copy-pasteable markdown review without modifying any code. ## Quick Start Ask the assistant to review the current branch changes using the kiss skill and report design findings with confidence tags.
