What problem does it solve? Codebases accumulate shallow modules whose interfaces are nearly as complex as their implementations, making code hard to test and navigate. This Skill surfaces those architectural friction points and proposes concrete deepening refactors, so you can decide what to fix with evidence instead of gut feel. ## Core Features & Use Cases - Hot-spot-driven exploration: Scopes the scan using git history and user direction, then explores the codebase for shallow modules, seam leakage, and poor locality. - Visual HTML report: Generates a self-contained HTML file (Tailwind and Mermaid via CDN) in the OS temp directory with before/after diagrams, recommendation-strength badges, and a top recommendation. - Decision grilling loop: After you pick a candidate, walks the decision tree with the /grilling skill, keeps CONTEXT.md and ADRs current, and respects existing architectural decisions. - Use Case: Point it at a subsystem where changes keep hurting — it identifies that your order intake pipeline is six shallow wrappers deep, renders the collapse into one deep module as a diagram, and grills you through the refactor trade-offs. ## Quick Start Ask the assistant to review the architecture of the current codebase and show deepening opportunities as an HTML report.
