What problem does it solve? Codebases accumulate shallow modules, leaky seams, and scattered logic that make testing and navigation painful. This Skill surfaces those architectural friction points and presents concrete deepening refactors as a visual report, so teams can decide what to fix first. ## Core Features & Use Cases - Architecture exploration: Uses an Explore sub-agent to walk the codebase, applying the deletion test and depth analysis to find shallow modules, leaking seams, and poor locality. - Visual HTML report: Generates a self-contained HTML file in the OS temp directory with Tailwind and Mermaid diagrams showing before/after visualizations, recommendation strength badges, and a top recommendation. - Guided design grilling: After the user picks a candidate, runs a grilling loop to refine the design, updates CONTEXT.md with new domain terms, and offers ADRs for load-bearing rejections. - Use Case: A team inherits a codebase where order processing logic is scattered across six thin wrappers. Run this Skill to get a report showing how to collapse them into one deep module, then grill through the new interface design. ## Quick Start Ask the assistant to review this codebase for architectural deepening opportunities and present the candidates as a visual report.
