codex-workflow

Author and run a custom Workflow (the Workflow tool's agent()/pipeline()/parallel() orchestration, a.k.a. "ultracode") that BLENDS Codex headless (codex exec) nodes into otherwise-Claude orchestration — for cross-model adversarial verification, judge panels with a Codex juror, and second-opinion generation. This is "Pattern A": the orchestration logic stays in Claude's Workflow JS, and selected nodes shell out to a genuinely different model family (the Codex CLI / GPT) to catch correlated Claude failure modes. Use this skill whenever the user asks to run a task as a "custom workflow using codex", "a workflow that mixes in codex", "blend codex into a custom workflow", "cross-model verify while orchestrating", "have codex verify/double-check the findings", "use codex as a verifier/juror/second opinion in the workflow", "Claude and codex both in one workflow", or any equivalent phrasing. Trigger even when the user only implies it — if they want a Workflow AND a second model family in the loop, this is the skill. Do NOT use it for a pure single Codex handoff (use a dedicated codex handoff command/agent instead), for codex image generation, or for a plain Claude-only Workflow with no second model.
