Every agent is a real terminal.

No wrappers, no chat-only sandboxes: each agent is a live PTY session you can click into and steer mid-task — inside a full developer environment with files, Git, and a session manager that keeps a fleet light.

Every agent is a real terminal.

Every agent is a real CLI session in a real terminal — Claude Code, Codex, Grok Build, or any CLI you bring. Implementers publish their work with the commands and tests that prove it; reviewers run the code before they let it through.

Simulated sessions. In the studio every agent terminal is a live PTY docked right in your workspace — click into one and steer an agent mid-task without breaking the run.

A full developer environment, not a chat window.

Agents with MCP tools and skills, autonomous loops on a schedule, every sprint across every workspace, and a specialist picker one keystroke away. Spawn an agent from the sidebar and check exactly which model is in the seat.

Click around — the sidebar, Automations, Sprints, and the agent picker behind the spark button in the title bar all work.

The Files and Git panels share one working tree — stage a file, write the message, commit, and watch it land in the log.

Idle sessions pause themselves.

Every agent session is a real runtime, and real runtimes eat memory — a single Claude Code process can hold hundreds of megabytes. So the studio quietly pauses any terminal you haven't touched for 15 minutes and releases its memory. Click back in and it resumes where it left off.

Sessions idle for 15 minutes pause automatically and release their memory. Click back in and they resume where they left off.

The session manager, live — pause a session and watch its memory come back; resume it whenever.
