What problem does it solve? Plans often ship with unchallenged premises, hidden failure modes, and scope that is either too timid or too bloated. This Skill performs a founder-mode review of an implementation plan before any code is written, catching landmines early and forcing explicit scope decisions. ## Core Features & Use Cases - Four Review Modes: SCOPE EXPANSION (dream big), SELECTIVE EXPANSION (hold scope plus cherry-picked expansions), HOLD SCOPE (maximum rigor), and SCOPE REDUCTION (strip to essentials), each chosen explicitly by the user. - System Audit and Failure Mapping: Runs a pre-review audit of git history, TODOs, and design docs, then maps error paths, shadow data flows, edge cases, and observability gaps. - Structured Decision Gates: Every scope change is presented as an individual AskUserQuestion with recommendations and completeness scores, so the user stays in control. - Use Case: Before implementing a new feature, run this review to challenge whether the plan is ambitious enough, verify every error path is named and tested, and produce a GSTACK REVIEW REPORT appended to the plan file. ## Quick Start Ask the AI to run a CEO review on the current branch's plan and challenge whether the scope is ambitious enough.
