What problem does it solve? Codebases accumulate shallow modules whose interfaces are nearly as complex as their implementations, making them hard to test and navigate. This Skill surfaces those architectural friction points and proposes concrete deepening refactors instead of leaving them buried in the code. ## Core Features & Use Cases - Hot-spot exploration: Scopes the review using git history and user direction, then explores the codebase for shallow modules, seam leakage, and poor locality. - Visual HTML report: Renders each candidate refactor as a self-contained HTML file with Tailwind and Mermaid before/after diagrams, recommendation-strength badges, and ADR conflict callouts, written to the OS temp directory. - Grilling loop: After the user picks a candidate, walks the decision tree on constraints, seams, and tests, updating CONTEXT.md and offering ADRs as decisions crystallize. - Use Case: A team notices their order intake flow is spread across six thin wrappers. Run this Skill to get a visual report of deepening candidates, pick one, and grill through the design before writing any code. ## Quick Start Ask the assistant to review this codebase for architecture improvements and show the deepening candidates as an HTML report.
