cli-anything-iterm2
Stateful CLI harness for iTerm2. Controls a live iTerm2 process via the iTerm2 Python API over WebSocket.
Prerequisites
- macOS + iTerm2 running:
brew install --cask iterm2 - Python API enabled: iTerm2 → Preferences → General → Magic → Enable Python API
- Install:
pip install cli-anything-iterm2(orpip install -e .from source)
Basic Syntax
cli-anything-iterm2 [--json] <group> <command> [OPTIONS] [ARGS]
Always use --json for machine-readable output (required for agent use).
Command Groups
| Group | Purpose |
|---|---|
app | App status, workspace snapshot, context management, app-level variables, modal dialogs, file panels |
window | Create, list, close, resize, fullscreen windows |
tab | Create, list, close, activate tabs; navigate split panes by direction |
session | Send text, inject raw bytes, read screen, full scrollback, split panes, prompt detection |
profile | List profiles, get profile details, list/apply color presets |
arrangement | Save and restore window layouts |
tmux | Full tmux -CC integration: bootstrap, connections, windows, commands |
broadcast | Sync keystrokes across panes via broadcast domains |
menu | Invoke any iTerm2 menu item programmatically |
pref | Read/write global iTerm2 preferences; list all valid keys; tmux settings |
Orienting in an Existing Workspace
Use app snapshot when you land in a session with existing panes and need to understand what's running without reading full screen contents for each pane:
cli-anything-iterm2 --json app snapshot
Returns name, current directory, foreground process, user.role label, and last visible output line for every session across all windows.
Naming convention — label panes when setting up a workspace so you can find them later:
cli-anything-iterm2 session set-var user.role "api-server"
cli-anything-iterm2 session set-var user.role "log-tail"
cli-anything-iterm2 session set-var user.role "editor"
app snapshot will surface these roles alongside process and path, giving you a full picture in one call.
Typical Agent Workflow
# 1. Orient — snapshot every session: name, path, process, role, last output line
cli-anything-iterm2 --json app snapshot
# 2. Establish context (saves window/tab/session IDs for subsequent commands)
cli-anything-iterm2 app current
# 3. Interact — no --session-id needed once context is set
cli-anything-iterm2 session send "git status"
cli-anything-iterm2 --json session scrollback --tail 200 --strip
# 4. Create a multi-pane workspace — label panes so snapshot identifies them later
cli-anything-iterm2 session split --vertical --use-as-context
cli-anything-iterm2 session send "python3 -m http.server 8000"
cli-anything-iterm2 session set-var user.role "http-server"
