`events` is the streaming interface an agent builds on, and it was the one verb whose JSON shape the reference did not give — every other one lists its fields exactly. Now it does: the externally tagged envelope, the four event kinds a listener sees, and the thirteen `layout` delta kinds. The prose also listed "pane exits" as an event type. There is no such event. `ControlEvent::PaneExited` is defined, encodes, and has a line `tty7 events` would print for it — and nothing anywhere constructs one outside the round-trip tests in its own file. `AgentStatus`, `Preempted` and `LayoutResync` have 2, 10 and 6 emitters respectively; this one has none. An agent waiting for a pane-exit line waits for good. What actually happens is checked against a running server: exit the shell in a pane and exactly one event arrives — a `layout` delta carrying `pane_facts` for that pane with `"live": false`, and the pane is gone from `pane ls --all`. The docs now say to watch for that, in a note that says outright there is no pane-exit line whatever the wire protocol's shape suggests. The variant keeps a comment saying the same thing, and that resolving it means either emitting it where the pane is reaped or removing it along with the `event_line` arm — not something to do in passing, since taking a variant out of a wire enum is a dialect change. 2951 tests pass.
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Editor-grade input — suggestions, completion, highlighting, history search
- Remote development — files, repos, panes, and git data stay on the remote machine
- Native SSH — profiles, SFTP, port forwarding, and jump hosts
- Agent-aware — Claude Code, Codex & co.: status, notifications, git context
- CLI + Skills — agents create panes, run commands, and inspect output
