What problem does it solve? Plans often ship with unchallenged assumptions, narrow scope, or hidden gaps in architecture, error handling, and security. This Skill runs an interactive CEO/founder-mode review that challenges premises, expands or reduces scope deliberately, and walks every finding past the user before anything changes. ## Core Features & Use Cases - Four review modes: Scope Expansion, Selective Expansion, Hold Scope, and Scope Reduction, chosen with the user at the start. - 11-section deep review: architecture, error/rescue mapping, security threat model, data flow edge cases, code quality, tests, performance, observability, deployment, long-term trajectory, and design/UX. - Outside voice cross-check: runs an independent second opinion via the Codex CLI or a Claude subagent, then surfaces cross-model disagreements for user decision. - Use Case: Before committing to a quarter-long build, ask for a strategy review of the plan to find the 10-star product framing, catch silent failure modes, and confirm the scope is ambitious enough. ## Quick Start Ask the assistant to run the plan-ceo-review skill on your current plan document to rethink scope and rigorously review it section by section.
