What problem does it solve? Before designing a new feature, teams need to understand what already exists in the codebase and what is missing. This Skill performs a structured gap analysis between approved requirements and the current code, producing multiple implementation options with effort and risk estimates. ## Core Features & Use Cases - Codebase Investigation: Scans existing modules, architecture patterns, conventions, and integration points relevant to the feature. - Multi-Option Analysis: Evaluates extend-existing, create-new, and hybrid implementation approaches with explicit trade-offs. - Effort & Risk Assessment: Labels work as S/M/L/XL effort and High/Medium/Low risk with justifications, and flags items needing further research. - Use Case: After approving requirements for a new payment feature, run the gap analysis to discover existing billing modules, identify missing capabilities, and save a research document that guides the design phase. ## Quick Start Run the gap validation for my feature to analyze how its requirements map against the existing codebase and save the findings to research.md.
