What problem does it solve? Coordinating a second AI agent to review code often produces redundant edits or conflicting changes. This Skill defines a lightweight cross-model review loop where the REVIEWER only sends findings and instructions while the IMPLEMENTER writes every line of code, keeping responsibilities cleanly separated. ## Core Features & Use Cases - Steer-only reviewer mode: The reviewer sends findings and instructions but never edits code; the implementer performs the initial build and every fix. - Shared coreview mechanics: Marker files, background watchers, and the autonomous finish sequence (curated commits, one no-ff merge, one docs(memory) commit) are inherited from the consolidated coreview skill. - Use Case: You want Claude to implement a feature while Codex reviews each round of the working tree without committing, looping until the reviewer says it is ready to ship. ## Quick Start Ask the agent to run coreviewlight so it implements the change while a second agent reviews the working tree and steers with findings until ready to ship.
