WezTerm Agent Deck

Monitor AI coding agents (Claude Code, OpenCode, Aider, etc.) in WezTerm. Shows status dots in tabs and notifications when agents need attention.

Inspired by agent-deck.

Quick Start

local wezterm = require('wezterm')
local agent_deck = wezterm.plugin.require('https://github.com/Eric162/wezterm-agent-deck')
local config = wezterm.config_builder()

agent_deck.apply_to_config(config)

return config

Configuration

agent_deck.apply_to_config(config, {
    update_interval = 500,  -- ms between status checks

    colors = {
        working = '#A6E22E',   -- green: agent processing
        waiting = '#E6DB74',   -- yellow: needs input
        idle = '#66D9EF',      -- blue: ready
        inactive = '#888888',  -- gray: no agent
    },

    icons = {
        style = 'unicode',  -- or 'nerd', 'emoji'
        unicode = { working = '●', waiting = '◔', idle = '○', inactive = '◌' },
    },

    notifications = { enabled = true, on_waiting = true },
})

Notifications with Sound (macOS)

WezTerm's native notifications don't support sound. For sound notifications on macOS, use terminal-notifier:

brew install terminal-notifier

agent_deck.apply_to_config(config, {
    notifications = {
        enabled = true,
        on_waiting = true,
        backend = 'terminal-notifier',  -- or 'native' (default)
        terminal_notifier = {
            sound = 'default',  -- or 'Ping', 'Glass', 'Funk', etc.
            title = 'WezTerm Agent Deck',  -- notification title
            activate = true,  -- focus WezTerm when notification clicked
        },
    },
})

Custom Rendering

Disable built-in display and use the plugin's detection in your own handlers:

agent_deck.apply_to_config(config, {
    tab_title = { enabled = false },
    right_status = { enabled = false },
    colors = { ... },
})

-- Custom tab title with status dots
wezterm.on('format-tab-title', function(tab)
    local formatted = {}
    for _, pane_info in ipairs(tab.panes or {}) do
        local state = agent_deck.get_agent_state(pane_info.pane_id)
        if state then
            table.insert(formatted, { Foreground = { Color = agent_deck.get_status_color(state.status) } })
            table.insert(formatted, { Text = agent_deck.get_status_icon(state.status) .. ' ' })
        end
    end
    table.insert(formatted, { Text = tab.tab_title or 'Terminal' })
    return wezterm.format(formatted)
end)

-- Custom status bar
wezterm.on('update-status', function(window, pane)
    for _, tab in ipairs(window:mux_window():tabs()) do
        for _, p in ipairs(tab:panes()) do
            agent_deck.update_pane(p)
        end
    end

    local counts = agent_deck.count_agents_by_status()
    local cfg = agent_deck.get_config()
    local items = {}

    if counts.waiting > 0 then
        table.insert(items, { Foreground = { Color = cfg.colors.waiting } })
        table.insert(items, { Text = counts.waiting .. ' waiting ' })
    end

    window:set_right_status(wezterm.format(items))
end)

API

agent_deck.get_agent_state(pane_id)      -- { agent_type, status }
agent_deck.get_all_agent_states()        -- all pane states
agent_deck.count_agents_by_status()      -- { working=N, waiting=N, ... }
agent_deck.get_status_icon(status)       -- configured icon
agent_deck.get_status_color(status)      -- configured color
agent_deck.update_pane(pane)             -- trigger detection
agent_deck.get_config()                  -- current config

Supported Agents

OpenCode (including Plan mode), Claude Code, Gemini, Codex, Aider. Add custom agents:

agents = {
    my_agent = {
        patterns = { 'my%-agent' },
        status_patterns = {
            working = { 'thinking' },
            waiting = { 'y/n' },
        },
    },
}

Development

-- Load locally for development
local agent_deck = dofile('/path/to/wezterm-agent-deck/plugin/init.lua')
