ChatGPT Pro Coding Agent

Operate a two-agent engineering loop. Codex owns intent, repository truth, permissions, integration, and the final completion claim. ChatGPT Pro supplies deep analysis and candidate implementation through the user's own supported ChatGPT Web surface.

Require Node.js 20+, Python 3.12, uv, ChatGPT Apps/Developer Mode access, upstream daijro/camoufox, and an HTTPS route for web connections.

Choose the transport

Prefer the MCP lane when ChatGPT Developer Mode/Plugins can call a custom Server URL:

1. Use CodexPro with one explicit workspace root.
2. Start in handoff mode for planning or when write authorization is unclear.
3. Use workspace write mode only when the user explicitly wants local changes.
4. Keep bash safe; use --no-bash for untrusted repositories.

Use the bundle lane only when the selected ChatGPT surface cannot call MCP. Read references/bundle-fallback.md before creating or uploading a ZIP.
