What problem does it solve? Codebases accumulate speculative abstractions, hand-rolled standard library behavior, unnecessary dependencies, and wrappers around native platform features. This Skill provides a structured review workflow that identifies what can be deleted, replaced with stdlib or native features, or deferred until a real requirement exists. ## Core Features & Use Cases - Four Review Modes: Run a prebuild check before implementing, review a diff for bloat, audit an entire repo for simplification candidates, or collect a debt ledger of deliberate simplifications marked with simplicity: comments. - Minimal-Correct-Change Ladder: A seven-step decision ladder that prioritizes reusing local code, standard library, native platform features, and existing dependencies before writing new code. - Tagged Findings: Findings are labeled with actionable tags (delete, stdlib, native, yagni, shrink, reuse) and ranked by expected cut and risk. - Use Case: Before adding a new utility library to a project, run a prebuild review to check whether the standard library or an already-installed dependency solves the requirement, avoiding a new dependency entirely. ## Quick Start Ask the assistant to run a simplicity review on the current diff and list anything that can be deleted or replaced with standard library or native platform features.
