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"

Reference Files

Read only what the task requires — each file is a single narrow concern (~10–30 lines):

references/layout-arrangement.md	Save and restore window layouts
references/app-context.md	Snapshot (orientation), status, context management, app vars, modal dialogs, file panels
references/profile-pref.md	Profiles list/get/presets, preferences read/write, tmux pref shortcuts
references/broadcast-menu.md	Broadcast keystrokes to multiple panes, invoke menu items
references/tmux-commands.md	All tmux CLI commands (bootstrap, send, tabs, create-window, set-visible)
references/tmux-guide.md	Full tmux -CC workflow, pane→session ID mapping
references/json-session.md	--json schemas for session, window, tab, screen, scrollback, inject
