🍋🥤 lemonaid

Monitor progress of and switch between lemons (go on... say 'LLMs' three times fast) running in the terminal.

How It Works

Lemonaid has two parts: hooks that fire when your lemons need attention, and a TUI (lma) that shows what's going on and lets you jump to sessions.

1. You add hooks to Claude Code, Codex CLI, and/or OpenCode (see Integrations below)
2. When a session stops or needs input, the hook writes a notification to a local SQLite database
3. The lma TUI displays active notifications, watches transcripts for live activity, and auto-archives sessions when they end
4. When you select an active session, you are taken directly to that pane/tab in tmux/WezTerm
5. Over time, archived sessions accumulate into a searchable session history — press h to browse past sessions across all projects and resume them

The TUI doesn't need to be running for notifications to arrive (hooks write directly to the DB), but it does need to run for live activity updates and automatic archiving.

Features

• Notification inbox: Track which Claude Code, Codex CLI, OpenClaw, and OpenCode sessions need your attention, and what they're doing as they do it
• Terminal integration: Hit enter to jump directly to the waiting session's pane (supports tmux and WezTerm)
• Session history & resume: Browse archived sessions across all projects, filter by name/cwd/branch, and resume directly or copy the command
• Bootstrap: lemonaid claude bootstrap imports historical Claude sessions from before lemonaid was installed into the archive
• Scratch pane (tmux): Toggle an always-on inbox with a keybinding - no startup delay, auto-hides after selection
• Auto-refresh TUI: See new notifications appear without losing your place

Assorted helpers

• Claude statusline: Colorful statusline showing time, elapsed, git branch, context %, vim mode
• tmux session templates: Spin up new named workspaces with a predefined window layout
• tmux window status formatting: An optional tmux integration to keep your status bar sane

🍋 Integrations

Claude Code

Add hooks to ~/.claude/settings.json:

{
  "hooks": {
    "Stop": [{ "hooks": [{ "type": "command", "command": "lemonaid claude notify" }] }],
    "Notification": [{ "matcher": "permission_prompt", "hooks": [{ "type": "command", "command": "lemonaid claude notify" }] }]
  }
}

Features: auto-dismiss via transcript watching, live activity updates, binary patch for faster notifications.

Full documentation: docs/claude.md | Binary patch

Codex CLI

Add to ~/.codex/config.toml at the very top (before any [table] headers):

notify = ["lemonaid", "codex", "notify"]

Features: auto-dismiss via session watching, live activity updates.

Full documentation: docs/codex.md

OpenClaw

Register from within an OpenClaw TUI session:

!lemonaid openclaw register

Features: turn-complete detection, live activity updates, auto-dismiss on user input.

Full documentation: docs/openclaw.md

OpenCode

Add this plugin at ~/.config/opencode/plugins/lemonaid.js (or .opencode/plugins/lemonaid.js in a project):

export const LemonaidPlugin = async ({ $ }) => ({
  event: async ({ event }) => {
    if (event.type === "session.idle" || event.type === "permission.asked") {
      await $`lemonaid opencode notify ${JSON.stringify(event)}`
    }
  },
})

Features: idle/permission notifications via plugin hooks, auto-dismiss via session DB watching, live activity updates.

Full documentation: docs/opencode.md

Terminal Setup

• tmux: See docs/tmux.md for pane switching, back navigation, session templates, and window colors
• WezTerm: See docs/wezterm.md for workspace/pane switching setup

Usage

# Open the inbox TUI
lma

# Or via the full CLI
lemonaid inbox

# List notifications (non-interactive)
lemonaid inbox list

TUI Keybindings

Key	Action
Enter	Open notification (switches to that session)
u	Jump directly to earliest unread session

a	Archive (remove from list)
r	Rename session (clear to revert to auto-name)
h	Toggle session history
c	Copy resume command (in history mode)
/	Filter history
g	Refresh
q / Escape	Quit

All keybindings are configurable. See docs/keybindings.md.
