Coding agents

Your agent writes into it on every plan.

There is no agent add-on and no per-seat anything. Claude Code, Codex and Cursor connect with one prompt or one command; Claude.ai and ChatGPT connect over MCP and sign you in. Pages they file count against the same numbers your own typing does.
