 - **Context feed** — palette commands send the current selection or the repo's `git diff` to the running agent as a ready-made prompt
 - **Tray icon** — a system tray / menu bar item that flips to an attention state the moment any agent needs your input; its menu lists every agent pane (brand avatar + status dot, click to reveal), switches the notification policy, and offers *Quit and Stop Server…* alongside the plain session-keeping quit (`show_tray_icon`, on by default)
 - **`tty7 wait`** — the CLI's orchestration primitive: block until a pane's agent needs input or finishes its turn (`tty7 wait %3 --until waiting,done --changed --timeout 600`, exit 124 on timeout), so one agent can sleep until its peer blocks on a permission prompt instead of screen-scraping — then `tty7 capture %3 --plain` to read the result. The agent status is a level, not an event, so `--changed` ignores the state the pane was already in when the wait began; without it, the JSON's `stale` flag says whether the answer might belong to the previous turn
-- **Orchestration skill** — a switch (Settings → Agents) that installs a Claude Code skill (`~/.claude/skills/tty7-orchestration`) teaching a *primary* agent the delegation loop — spawn a worker pane, send it a bounded task, `wait` on it, capture the result. A skill rather than a global instruction on purpose: only its one-line description rides in context until explicitly invoked, and worker agents never inherit orchestration authority
 - **`tty7` on PATH** — the CLI ships inside every installer and is put on PATH at launch, so a script or a coding agent can drive tty7 from any terminal. Inside a tty7 pane it works regardless, since panes inherit the app's environment. On Unix it is a symlink into whichever of `/opt/homebrew/bin`, `/usr/local/bin`, `~/.local/bin`, `~/bin`, `~/.cargo/bin` your PATH already covers; on Windows the install directory is appended to your user PATH, and the uninstaller takes it back out. A `tty7` you installed yourself is left alone, never replaced. Off via Settings → Agents or `install_cli_on_path: false` in `config.json`

 - **上下文回填** —— 面板命令把当前选区或仓库 `git diff` 打包成 prompt 直接喂给正在跑的 agent
 - **托盘图标** —— 系统托盘 / 菜单栏常驻图标，任何 agent 等你输入时立即切换为提醒态；菜单列出所有 agent pane（品牌头像 + 状态点，点击直达）、可切换通知策略，并在保留会话的普通退出之外提供 *退出并停止服务器…*（`show_tray_icon`，默认开启）
 - **`tty7 wait`** —— CLI 的编排原语：阻塞到某个 pane 的 agent 等待输入或完成一轮（`tty7 wait %3 --until waiting,done --changed --timeout 600`，超时退出码 124），让一个 agent 睡到同伴卡在权限确认的那一刻，而不是抓屏猜——然后 `tty7 capture %3 --plain` 收结果。agent 状态是电平不是边沿，所以 `--changed` 会忽略 wait 开始时 pane 本来就处在的那个状态；不加它的话，JSON 里的 `stale` 标记会告诉你这个答案是不是上一轮留下的
-- **Orchestration skill** —— 一个开关（设置 → Agents），安装一个 Claude Code skill（`~/.claude/skills/tty7-orchestration`），教 *primary* agent 完整的委派循环——开 worker pane、发一个边界清晰的任务、`wait` 等待、收结果。特意做成 skill 而非全局指令：平时只有一行描述占上下文，显式调用才加载全文，worker agent 也不会继承编排权限
 - **`tty7` 上 PATH** —— CLI 随每个安装包一起发布，启动时自动放到 PATH 上，脚本和 coding agent 在任何终端里都能驱动 tty7。tty7 自己的 pane 里则一定可用，因为 pane 继承 app 的环境。Unix 上是往 `/opt/homebrew/bin`、`/usr/local/bin`、`~/.local/bin`、`~/bin`、`~/.cargo/bin` 中你 PATH 已经覆盖的那个目录里放一个软链；Windows 上是把安装目录追加到用户 PATH，卸载时再摘掉。你自己装的 `tty7` 一律保持原样，不会被覆盖。关掉：设置 → Agents，或 `config.json` 里 `install_cli_on_path: false`
