What problem does it solve? Non-trivial implementation work in a Codex session often needs a separate execution pass, but handing an unresolved plan to another agent causes scope creep and redesign. This Skill enforces a strict workflow where Codex freezes the plan, Grok CLI executes it, and Codex reviews and verifies the result. ## Core Features & Use Cases - Session Gate: Applies only inside a Codex session and explicitly forbids nested Codex invocations, keeping planning in the coordinator. - Frozen Plan Contract: Requires the plan to specify files, ordered steps, exact verification commands, and risks before delegation. - Grok Execution & Follow-Up: Provides ready prompt-file templates for initial execution and narrow follow-up fixes, with a two-round failure limit before the coordinator takes over. - Use Case: You have a refactor with a known outcome but an unclear file-level path. Freeze the plan in Codex, delegate execution to Grok CLI with grok --prompt-file, then review the diff and run the tests yourself. ## Quick Start In a Codex session, ask the agent to use the codex-grok workflow to freeze your implementation plan and delegate execution to Grok CLI.
