Keep your AI coding agents in your Mac's notch — see progress, approve commands, answer questions
Each active AI coding session becomes a card ordered by urgency — approvals and questions first, work in progress next, unread finishes last.
Answer command, file-edit, and plan approvals directly in the notch. Approve once, for the entire session, or persistently where Claude Code suggests a rule.
Read the agent's full plan on the card, then approve it or request changes before any code lands.
Jump lands on the session's own terminal tab or split pane — including tmux and Herdr panes — or its conversation in the Claude or ChatGPT desktop app.

A multitasking macOS terminal and agent manager for orchestrating AI coding agents
Run several CLI agents in one project simultaneously, each isolated in its own git worktree and branch so sessions never collide.
Anoint an orchestrator that genuinely monitors workers and reads their terminals, or convene a roundtable of role-played agents in a shared chat via crystl quest.
Turns, tool calls, results and tables are captured as agent-readable metadata and rendered fast on the GPU with Metal.
Approval requests, questions and alerts appear as color-coded glass cards, while a panel tracks token burn and estimates turns left.
