## Description

Use the signed-in ChatGPT website in Chat UI Pro mode, never Work mode, to research, architect, and review one local project through a configured Secure Tunnel and read-only MCP, while Codex alone edits and tests locally. Trigger on explicit $yichen-codex-chatgpt, 让 ChatGPT 设计后由 Codex 写代码, ChatGPT 架构并审查 Codex, or requests for a Codex and ChatGPT collaboration loop. Pure research stays on the official ChatGPT website; code and hybrid work follow ChatGPT PLAN to Codex execution to ChatGPT REVIEW. Website control defaults to in-app browser, then Chrome, then bounded Computer Use. Use a compatible local-only MCP only when the user explicitly requests local-only mode and that optional dependency is configured, never as an automatic fallback.

# Codex × ChatGPT

Use the user's signed-in ChatGPT Chat UI with the active model route visibly labeled `Pro` as the researcher, architect, and reviewer. Codex is the only code writer and command/test executor.

```text
User in Codex
  → ChatGPT Pro researches and/or reads the project through the Secure Tunnel
  → ChatGPT returns PLAN
  → Codex edits and tests locally
  → ChatGPT reads the real diff and verification evidence through the Tunnel
  → ChatGPT returns REVIEW
  → DONE, one bounded repair cycle, or a reported blocker
```

The ChatGPT website UI is the control channel for short protocol messages. The Secure Tunnel and `remote-review` MCP are the data channel for local code, diff, and verification evidence. Do not paste code, diffs, logs, secrets, or absolute local paths into the ChatGPT composer.

## Website Control Surface Priority
