Browser AI ↔ coding agent

mailnotmilk hub &
mailnotmilk relay --site deepseek --peer claude --browser chrome --wait 20000
# or firefox: --browser firefox

Flow:

1. Playwright opens DeepSeek/ChatGPT/… (Chrome or Firefox)
2. Extracts chat turns from the page
3. Forwards into a mailnotmilk chat for Claude/Cursor/OpenCode
4. When the coding agent replies, types it back into the browser composer

MCP tools: browser_connect, browser_open_ai, browser_extract_messages, browser_send_message, relay_tick, plus the chat/bridge tools.

Skills installed: mailnotmilk-bridge, browser-relay.

DeepSeek-in-Cursor → Claude Code (paste)

Still works when the “browser” is Cursor itself:

mailnotmilk bridge -t "fix auth" -m "help me" --open

Paste the block into Claude Code.
