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, presented visually rather than as a wall of prose. ## Core Features & Use Cases - Hot-spot-driven 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: Generates a self-contained HTML file in the OS temp directory using Tailwind and Mermaid via CDN, with before/after diagrams, recommendation-strength badges, and ADR conflict callouts for each candidate. - Guided decision loop: After the user picks a candidate, runs a grilling workflow that updates the domain glossary in CONTEXT.md and offers ADRs for load-bearing rejections. - Use Case: A team notices their order intake flow is scattered across six thin wrappers. Run this Skill to get a visual report of deepening candidates, pick one, and walk through the refactor decision interactively. ## Quick Start Ask the assistant to review this codebase for architecture deepening opportunities and show the results as an HTML report.
