What problem does it solve? Plans often ship with hidden failure modes, unexamined scope, and missing error handling. This Skill performs a rigorous CEO-style plan review that challenges the premise, maps every error path, and forces explicit scope decisions before any implementation begins. ## Core Features & Use Cases - Scope Mode Selection: Choose between scope expansion, selective expansion, hold scope, or scope reduction, with context-dependent defaults based on plan type. - Eleven-Section Review: Systematically evaluates architecture, error handling, security, data flows, code quality, tests, observability, database design, API contracts, performance, and UX. - Implementation Alternatives: Produces 2-3 distinct approaches with effort and risk estimates before recommending one, requiring explicit user approval. - Use Case: Before starting a multi-file feature, run a CEO review to catch missing error handling, unmapped edge cases, and scope creep, then receive a summary of accepted scope and deferred items. ## Quick Start Ask the assistant to run a CEO review on your implementation plan and challenge its scope before writing any code.
