What problem does it solve? Engineering plans often contain hidden architecture flaws, missing edge cases, scope creep, and inadequate test coverage that only surface during implementation. This Skill performs an engineering-manager-style review of a plan or design doc before any code is written, catching issues early when they are cheapest to fix. ## Core Features & Use Cases - Scope Challenge (Step 0): Identifies existing code that already solves sub-problems, flags complexity smells (8+ files or 2+ new services), and recommends minimal-change approaches with web-searched best practices. - Interactive Section Reviews: Walks through Architecture, Code Quality, Tests, and Performance one issue at a time via structured questions, each with an opinionated recommendation and completeness scoring. - Test Coverage Mapping: Traces every codepath in the plan, draws ASCII diagrams of branches and error paths, and ensures the plan includes tests for 100% coverage before implementation starts. - Use Case: Before implementing a new feature, run this review on your design doc to catch a missing error-handling path in the data flow and an over-engineered service boundary, then lock in a revised plan. ## Quick Start Ask the AI to run an engineering review of the current plan or design doc for this branch before starting implementation.
