I gave Claude Code a crew. Codex and Gemini found a race in the plugin that runs them.

Description and use

Crewmate automates offloading tasks from Claude to Codex and Gemini, streams live progress, and manages job lifecycle within Claude Code.

Problem

Integrate Claude with external LLMs (Codex, Gemini) to offload tasks, stream progress, and handle job lifecycle without manual copy‑paste.

Outcome

Crewmate enables seamless, automated second‑opinion workflows, revealing race conditions and improving code quality.

Workflow

• Install crewmate via plugin marketplace
• Run /crewmate:setup to verify dependencies
• Use /crewmate:ask <model> <prompt> to start a job
• Watch progress with /crewmate:watch --brief <job-id>
• Retrieve final result with /crewmate:result <job-id>
• Optionally use /crewmate:critique to send diffs to both models

Evidence

crewmate is a Claude Code plugin that lets Claude hand a task to OpenAI Codex or Google Gemini, keep working, and watch every step land in the conversation.

Source

Each job runs in the background. Claude carries on, and the answer is waiting when the job ends, even if you closed the session.

Source

A job ends done, failed, timeout or canceled, with the reason and any tools the other model was denied.

Source

Codex and Gemini both flagged the same race.
