What problem does it solve? Plans often ship with unchallenged assumptions, narrow scope, and hidden failure modes. This Skill stress-tests a plan the way a CEO or founder would: questioning premises, expanding or reducing scope deliberately, and forcing every finding through an explicit user decision before anything changes. ## Core Features & Use Cases - Four scope modes: SCOPE EXPANSION, SELECTIVE EXPANSION, HOLD SCOPE, and SCOPE REDUCTION, chosen interactively at the start of the review. - 11-section deep review: architecture, error and rescue mapping, security threat model, data flow edge cases, code quality, tests, performance, observability, deployment, long-term trajectory, and design/UX, each with mandatory per-finding user questions. - Outside voice cross-check: runs an independent second opinion via the Codex CLI or a Claude subagent, then surfaces cross-model disagreements for the user to resolve. - Use Case: Before committing a team to a quarter of work, run this review on the plan to catch unrescued error paths, missing rollback steps, and scope that is either too timid or too large. ## Quick Start Ask the agent to run a CEO-mode strategy review on the current plan to challenge its scope and find gaps before implementation.
