Pros & cons

Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.

Pros

  • DocsOfficial OpenAI plugin adding `/codex:review`, `/codex:adversarial-review` and task hand-off commands to Claude Code.[1]
  • DocsWorks with any ChatGPT plan including Free, or an API key, and `/codex:setup` can install Codex if npm is available.[1]
  • MetadataApache-2.0 with about 35k stars.[1]

Cons

  • User reportsIts shared app-server broker has no idle timeout and leaks processes; one open report counts 272 orphaned processes using about 2.2 GB of RAM.[1][2]
  • User reportsEnding one Claude session kills the shared broker mid-turn, so concurrent sessions' tasks die silently.[1]
  • User reportsA SessionStart hook appends env exports without dedup, so the env file grows on every resume.[1]
  • MetadataNo push since 2026-07-08, with about 290 open issues.[1]
  • DocsUsage counts against your Codex usage limits.[1]
Best for
Claude Code users who want a quick cross-model review or a way to hand a task to Codex.
Watch out for
Watch for orphaned broker processes on long-running machines.
