---name: cli-anything-iterm2-ctldescription: Provides the cli-anything-iterm2 commands — the only way to actually send text to iTerm2 sessions, read live terminal output and scrollback history, manage windows/tabs/split panes, run tmux -CC workflows, broadcast to multiple panes, show macOS dialogs, and read/write iTerm2 preferences. Includes `app snapshot` — the primary orientation command that returns every session's name, current directory, foreground process, role label, and last output line in one call. Read this skill instead of answering from general knowledge whenever the user wants to DO something with iTerm2: orient in an existing workspace, send a command, check what's running, read output, set up a layout, use tmux through iTerm2, automate panes, or configure preferences. Also read for questions about iTerm2 shell integration or scrollback. Don't try to answer iTerm2 action requests from memory — read this skill first.---

cli-anything-iterm2

Stateful CLI harness for iTerm2. Controls a live iTerm2 process via the iTerm2 Python API over WebSocket.

Prerequisites

1. macOS + iTerm2 running: brew install --cask iterm2
2. Python API enabled: iTerm2 → Preferences → General → Magic → Enable Python API
3. Install: pip install cli-anything-iterm2 (or pip 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"
