What problem does it solve? Codebases accumulate dead code, duplicate state, redundant layers, and ownerless abstractions that increase maintenance burden. This Skill provides a disciplined workflow to prove which code is genuinely removable and execute safe, validated simplifications. ## Core Features & Use Cases - Simplification Audit (Survey mode): Read-only investigation that ranks deletion candidates by confidence, blast radius, and maintenance concepts retired. - Authorized Simplification (Change mode): Proves each cut with consumer maps and contract analysis, removes the obligation vertically, and validates the surviving system in widening verification rings. - Boundary and Lifecycle Analysis: Maps validation, concurrency, and cleanup mechanisms to owners and failure windows before classifying them as redundant. - Use Case: Ask the agent to audit a repository for dead code and over-engineering; it returns ranked proof records showing reachability evidence, consequences, and the smallest check that would expose an incorrect cut. ## Quick Start Use the simplify-codebase skill to audit this repository and rank the safest high-impact simplifications without editing files.
