Send the next prompt without leaving the notch

Expand a session and the composer sits at the bottom, ready once the agent is waiting or idle. Type the next instruction and send: the reply streams into the session card as it's written, tool activity updates live on the timeline, and a prompt in flight can be cancelled. If the agent asks for permission or asks a question mid-turn, the same notch controls answer it.

In-notch prompts work for Claude Code, Codex, Cursor, Grok, Kimi, Hermes, OpenCode, and Pi sessions that carry a resumable provider session ID, each through its own native transport. A few stay view-only: Antigravity sessions, Cursor IDE-hosted sessions, remote Hermes dashboard sessions, and editor-hosted (ACP) sessions.

The moment an agent finishes a turn, its work is in the notch: the last reply, the diff counts, the checklist. When the next step is obvious, you send it from right there and drop back into your editor. No hunting for the right terminal among six sessions, no context switch, no idle agent sitting unnoticed.
