 "title": "Build with Opus through Claude Code, then check in Codex",
 "page_title": "How to build with Opus through Claude Code, then check in Codex with Codex on Crack",
 "summary": "Let Opus implement a whole assignment, then have the Codex host verify it in the browser.",
 "who": "A developer who prefers Claude for a build but wants Codex tools, such as browser checks or computer tools, to verify the result.",
 "problem": "External Claude sessions do not inherit Codex tools, so checking the finished build usually means a manual handoff.",
 "outcome": "Opus implements the assignment through Claude Code, and the Codex host runs the requested browser or computer checks and reports the evidence back.",
 "steps": [
  "Install the Claude Code CLI and confirm it is authenticated through your subscription.",
  "Run `codex plugin marketplace add \"$PWD\"` from this checkout in a stable folder.",
  "Run `codex plugin add codex-on-crack@codex-on-crack`.",
  "Start a fresh conversation and ask Codex to have Opus implement the assignment through Claude Code.",
  "Ask the Codex host to check the result in the browser and report what it found."
 ],
 "agent_prompt": "With the codex-on-crack package in <project folder>, have Opus 5.5 implement <assignment> through Claude Code, then ask the Codex host to open the result in the browser and report any problems. Expected output: the implementation plus a browser check summary. Verify that the browser evidence comes from the Codex host, not from the Claude session.",
