tty7 — скилл

---
name: tty7
description: >-
  Drive the tty7 terminal workbench from the shell with the `tty7` binary — list workspaces/tabs/panes, split a pane, send text or keystrokes into one, capture what is on a pane's screen, run a command in a real PTY and pass its exit code through, run a command in a shell pane you already have and get back its output and exit code, block until a pane finishes or needs input, see which coding agents are running and which ports a pane is listening on. Use this whenever tty7, panes, workspaces, or `%42`/`@7`/"the other pane"/"the other agent" come up; whenever you want to hand work to another agent and collect the result ("get Claude/Codex to do X", "派个活", "let another agent handle this", running several agents in parallel and merging what they produce); whenever you need to start something long-running or interactive (dev server, REPL, ssh session, `tail -f`, a TUI) that should not sit blocking your Bash tool; whenever a program needs a real terminal to behave the way the user sees it; and whenever you need to look at or report on what is running in some *other* terminal on this machine. Cheap to check: if `$TTY7_PANE` is set you are already inside tty7 and every command here works with no setup.

# Driving tty7 from the command line

`tty7` is a thin, non-interactive client of the tty7 server. Every verb returns
and exits; `--json` makes the output machine-readable. The GUI never has to be
running — the server is what owns the panes.

## First: where are you?

```bash
tty7 doctor
```

One table, and it answers everything you need before doing anything else:
whether a server is reachable, whether the dialect matches, whether each agent's
status hooks are installed, and whether `TTY7_CONFIG_DIR` / `TTY7_WS` /
`TTY7_PANE` are set — i.e. whether you are running *inside* a tty7 pane.

Being inside a pane matters for two reasons: the address-taking verbs
(`split`, `send`, `exec`, `capture`, `procs`, `wait`, `pane close`) default to
`$TTY7_PANE`, and `run --keep` files its pane into `$TTY7_WS`. Outside a tty7
shell you must name a target explicitly, and the error will say so rather than
guessing.

The hooks row matters if you intend to delegate to another agent: without them
an agent reports no status, so `tty7 wait` on it will only ever time out.

If `tty7 doctor` says the server is unreachable, stop and tell the user — do
not run `tty7 server start` on your own initiative. Starting a server they
didn't ask for changes what their GUI attaches to.

## What are you here to do?

Four jobs, four shapes:

1. **Run something that shouldn't block you or needs a real TTY** — a dev
   server, a long test run, a TUI. [Running a command](#running-a-command-two-shapes).
2. **Talk to something stateful over time** — a REPL, `ssh`, a debugger.
   Same primitives: [send](#non-blocking-a-pane-you-talk-to-over-time),
   [read](#reading-a-pane), repeat.
3. **Look at what this machine is doing** — other panes, other agents, ports.
   [Looking around](#looking-around), strictly read-only.
4. **Hand work to another coding agent** — one worker or a fan-out of several.
   Read `references/delegation.md` first; the short version is
   [below](#handing-work-to-another-agent).

The Bash tool remains right for anything that starts, does its job, and exits
without needing a terminal or an audience. A pane earns its keep when the
process outlives your turn, needs a real PTY, or should be visible to the user
in their tty7 window — that last one is often the whole point.
