Clawd Buddy

A tiny animated terminal pet that sits on your taskbar and reacts to Claude Code events. Works on Windows and Linux.

What it does

Clawd Buddy is a small always-on-top character that lives on your taskbar while you work with Claude Code:

State	What happens
Idle	Gently bobs, blinks, breathes — your quiet companion
New session begins (UserPromptSubmit hook, first prompt)	Greets with a soft wave, a smaller smile, and a pulsing cyan border
Assistant is thinking (between UserPromptSubmit and Stop)	Pupils sweep upward, three pulsing dots float above the head, gentle purple border
Assistant finishes (Stop hook)	Celebrates with confetti, happy eyes, waving arms, a short motivational fanfare, and a pulsing green border
Assistant needs permission (PermissionRequest hook)	Waves with a floating !, a warm two-note doorbell call, and a pulsing yellow border

If multiple signals arrive in quick succession (e.g. a PermissionRequest while a celebrate is still animating), the buddy now queues them instead of dropping them — up to three pending reactions play back in the order they arrived.

Notification sound packs

Pick the audio style from the system-tray right-click menu → Sound. Four packs ship in the box, plus an Off entry to mute. Clicking a pack previews the celebrate sound immediately so you can audition options without waiting for the next event.

Pack	Celebrate	Wave
Fanfare (default)	Motivational ascending C-major arpeggio that lands on a full triad chord	Warm two-note doorbell (G4 → D4)
Chime	Two ascending bell tones with harmonic decay	Single lower bell
Retro	8-bit square-wave coin-pickup flourish (C5 → E5 → G5 → C6)	Two short low-high blips
Minimal	Single short soft pip	Single short low pip
Off	(silent)	(silent)

No audio file is bundled — every pack is synthesized at startup with pygame.mixer (summed sine / square / bell-decay voices with raised-cosine envelopes). Your choice persists across launches in config.json under "sound_pack".

Toggle from the system-tray right-click menu → Sound. The choice is remembered between launches (saved alongside the theme in config.json). If your machine has no audio device, the buddy logs a one-line warning and runs silently while the visual border still works.

Comfort & accessibility

Three preferences keep the buddy polite across motion sensitivities, audio environments, and quiet hours:

• Reduce motion (system-tray → Reduce Motion toggle). When on, the buddy stops bobbing, swinging limbs, and spawning confetti. The pulsing colored border and notification sounds remain — the signaling minimum — so you can still tell when Claude is greeting, thinking, waving, or celebrating.
• Volume (system-tray → Sound → Volume). Discrete steps from 0% to 100% scale the active pack's per-event base levels (celebrate is intentionally louder than wave). Clicking a level previews the celebrate sound at the new volume.
• Quiet hours (system-tray → Sound → Quiet Hours). Pick a preset window — typical nights, e.g. 23:00 – 08:00 — and the buddy mutes every notification sound inside the window (the visual animations still play). The schedule wraps across midnight. Choose Off to disable.

All three settle into config.json under reduce_motion, volume, and quiet_hours ({start, end} minutes-from-midnight) — the same file as the theme and sound pack. Defaults: motion on, volume 100%, quiet hours off.

Water reminder

The buddy can nudge you to drink water on a schedule. Off by default — turn it on from the system tray (Water Reminder toggle) or from the About → Reminders tab where every preference lives:

Setting	Options
Interval	30 min, 1 h (default), 1.5 h, 2 h, 4 h — picked from a scrolling dropdown directly under the Remind me to drink water checkbox
Start reminders at	HH:MM combobox (30-min steps, default 08:00). The day's schedule cycles from this anchor: with start=09:00 and interval=1 h, reminders land at 09:00, 10:00, 11:00, …
Sound	water (default — high-pitched bell), chime (calmer two-bell pair), beep (square-wave triple-blip), or off for visual-only
Quiet hours	Default 23:00–08:00, edited via HH:MM comboboxes in 30-min increments. Pick the same time for both endpoints to disable.

When the reminder fires:

• The chosen sound plays once (no looping nag).
• The buddy shows a "Drink water!" speech bubble until you ack.
• Press Space to acknowledge — the bubble clears. The next scheduled slot still fires on time (drinking ack doesn't shift the schedule). Space keeps its old "test celebration" meaning at every other moment, so you haven't lost the shortcut.
• Or click I drank water in the tray menu (visible only while an alarm is active).
• Or signal externally: clawd-buddy --drank works the same way for smart-bottle integrations, wrist macros, or scripts.

Inside quiet hours the buddy silently consumes the scheduled slots — on exit, only the next future slot fires, not every slot you were meant to sleep through. Reminder prefs persist under a reminder block in config.json (enabled, interval, anchor_minute, sound, quiet_hours).

Drinking history

Every drink-ack — Space, the tray entry, the About-window button, or clawd-buddy --drank — increments a per-day cup counter that lives in ~/.clawd-buddy/history.json (C:\Users\<name>\.clawd-buddy\ on Windows, ~/.clawd-buddy/ on Linux). The path is intentionally separate from config.json — settings sit in the platform config dir, runtime data sits in the home directory where it's easy to back up or sync via dotfile management.

The About → Reminders tab shows:

• 3 cups today (bold headline, with singular/plural handling)
• Recent days: 6 · 5 · 7 · 4 · 5 · 6 · 3 (last 7 days, newest first)

Both lines tick live on the same 1 Hz refresh as the countdown, and update immediately when you click the I drank water now button.

Crossing local midnight closes out the in-progress day into the recent list and resets the count to zero. Empty days (zero acks) are skipped so the recent list only carries meaningful data.

Schema (small enough to hand-edit if you ever need to):

{
  "today":  { "date": "2026-05-25", "count": 3 },
  "recent": [
    { "date": "2026-05-24", "count": 6 },
    { "date": "2026-05-23", "count": 5 }
  ]
}

The counter is independent of whether the reminder is enabled — manual logging works either way, so you can use the buddy as a pure water- tracker without the nag.

Pomodoro mode

clawd-buddy --pomodoro 25/5    # 25 min work / 5 min break, repeating
clawd-buddy --pomodoro-stop    # end the cycle

The buddy runs the cycle so you don't have to watch a timer:

• Break starts → celebrate animation + "Break time!" bubble
• Break ends → wave animation + "Back to work!" bubble
• Repeats until you stop it (CLI, the tray's Stop Pomodoro entry — visible only while a cycle runs — or quitting the buddy)

Transitions ride the normal celebrate/wave channels, so your volume, quiet hours, and reduce-motion settings all apply. Phase boundaries are wall-clock deadlines: if the machine was asleep at the boundary, the transition fires as soon as the buddy notices, and the next phase still ends at its originally scheduled time. Work/break lengths accept 1–180 minutes each. The cycle is in-memory only — it does not survive a buddy restart. Check progress any time via --status (the pomodoro block shows phase, remaining seconds, and completed cycles).

HTTP webhook — drive the buddy from anything

clawd-buddy --http-port 8787              # start with the webhook enabled
curl -X POST localhost:8787/signal -d '{"action": "wave"}'
curl -X POST localhost:8787/signal -d '{"action": "message", "text": "CI green"}'
curl localhost:8787/status                # same JSON as --status

POST /signal accepts exactly the same JSON payloads as the TCP protocol — the webhook is a thin transport over the same dispatcher, so every action (celebrate, wave, message, pomodoro, …) works over HTTP automatically. GitHub Actions, n8n, IFTTT webhooks, or a two-line script can now make the buddy react.

Security posture:

• Opt-in — no --http-port, no listener.
• Localhost only — binds 127.0.0.1, always.
• --http-token TOKEN (optional) requires Authorization: Bearer TOKEN on every request.
• The quit action is rejected over HTTP (403) unless a token is configured — no unauthenticated curl-able kill switch.

Workspace badge — who just signaled?

Running several Claude Code sessions across workspaces, all driving the same buddy? A small one-letter badge above the buddy's left shoulder shows which workspace last signaled — so when a wave asks for permission, you know which window to switch to.

• The label comes from the Claude Code hook payload's cwd automatically (C:\dev\api → badge A); scripts can override with --workspace LABEL, and webhook callers can send {"action": "wave", "workspace": "ci"}.
• Each workspace keeps a stable color across restarts, so api is always the same tint.
• Self-suppressing: the badge only appears once a second distinct workspace signals — with one session running, the buddy looks exactly as it always did.
• Shows while the buddy is thinking and for ~8 s after a reaction; toggle it from the tray (Workspace Badge, persisted).

Themes

Clawd Buddy ships with 8 color themes — a mix of dark and light with several popular palettes:

#	Theme	Flavor
1	dark	Classic dark blue-gray (default)
2	light	Classic soft light
3	dracula	Dark with purple / pink accents
4	monokai	Dark with green / pink accents
5	nord	Cool nordic blue
6	gruvbox	Warm retro dark
7	solarized	Muted solarized light
8	sunset	Warm peach / orange light

Pick one at launch:

clawd-buddy --theme dark        # default
clawd-buddy --theme dracula
clawd-buddy --theme sunset

Switch at runtime from the Theme submenu on the system-tray icon (right-click the clawd-buddy tray icon → Theme → pick one). The active theme is marked as a radio item.

Your choice is remembered between launches. The buddy stores the last theme in:

• Windows: %APPDATA%\clawd-buddy\config.json
• Linux: $XDG_CONFIG_HOME/clawd-buddy/config.json (falls back to ~/.config/clawd-buddy/config.json)

Passing --theme <name> at launch overrides and updates the remembered theme, so the override sticks for next time too. First-run default is dark.

Platform support

Platform	Transparency	Always-on-top	Autostart
Windows 10/11	Color-key (fully transparent background)	Win32 HWND_TOPMOST	VBS in Startup folder
Linux (X11)	Themed background (dark or light)	_NET_WM_STATE_ABOVE	.desktop in ~/.config/autostart/

Linux notes: Requires an X11 session (Wayland restricts window positioning and always-on-top). Most Wayland desktops support XWayland — set SDL_VIDEODRIVER=x11 (done automatically). Panel/dock height is auto-detected via _NET_WORKAREA; falls back to 48px.

Quick start

1. Launch the buddy

clawd-buddy

The buddy appears on your taskbar, centered at the bottom of the screen. It runs until you close it.

2. Run at startup (optional)

# Enable — buddy starts automatically at login
clawd-buddy --startup

# Disable — remove from startup
clawd-buddy --no-startup

• Windows: Places a VBS launcher in shell:startup. No console window appears.
• Linux: Creates a .desktop file in ~/.config/autostart/.

3. Wire up Claude Code hooks

Add to your global Claude Code settings (~/.claude/settings.json) so every session triggers the buddy:

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "clawd-buddy --prompt-start",
            "timeout": 5000
          }
        ]
      }
    ],
    "Stop": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "clawd-buddy --send done",
            "timeout": 5000
          }
        ]
      }
    ],
    "PermissionRequest": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "clawd-buddy --wave",
            "timeout": 5000
          }
        ]
      }
    ]
  }
}

Note: If you already have other hooks in your settings.json, merge the new entries into the existing hooks object.

--prompt-start does two things in one: a soft greeting on the first prompt of each Claude Code session (de-duplicated by session_id read from the hook's stdin payload), then enters the thinking animation that runs until Stop arrives. Wiring it is optional — without it, the buddy still celebrates and waves, just without the session-start and mid-response reactions.

4. Done

Start a Claude Code session anywhere. When the assistant finishes or needs your attention, the buddy reacts.

CLI reference

clawd-buddy                  Start buddy on taskbar
clawd-buddy --test           Start with a celebration animation
clawd-buddy --send MSG       Signal a running buddy to celebrate

clawd-buddy --message TEXT   Show a 3s speech bubble with TEXT above the
                             running buddy. Pass "" to dismiss any
                             current bubble immediately.
clawd-buddy --status         Print the running buddy's state as JSON
                             (version, pid, port, mode, queue depth,
                             theme, sound pack, bubble, last action,
                             plus M3 comfort prefs and the M4 reminder
                             block) and exit. Exit 1 if no buddy is
                             listening.
clawd-buddy --drank          Acknowledge the water-drinking reminder
                             (clears any active alarm + resets the
                             timer). Exit 1 if no buddy is listening.
clawd-buddy --pomodoro W/B   Start a pomodoro cycle on the running buddy.
                             W/B are minutes (1-180 each), e.g. 25/5.
                             Celebrates at break, waves back to work,
                             repeats until stopped.

                             on 127.0.0.1:N — POST /signal mirrors the
                             TCP protocol, GET /status mirrors --status.
clawd-buddy --http-token T   (launch flag) Require "Authorization:
                             Bearer T" on every HTTP request. Without a
                             token, the HTTP quit action is rejected.

                             Auto-derived from the hook cwd when omitted.
clawd-buddy --prompt-start   Signal start of a Claude Code prompt — greets
                             on the first prompt of a new session, then
                             enters the thinking animation. Reads
                             session_id from JSON on stdin when run as a
                             hook command.

How it works

Architecture

Claude Code                                          Clawd Buddy
-----------                                          -----------
 hooks/UserPromptSubmit ──> clawd-buddy --prompt-start ──> TCP:44556 ──> greet (if new session) + thinking
 hooks/Stop ─────────────> clawd-buddy --send ─────────> TCP:44556 ──> celebrate animation
 hooks/PermissionRequest ──> clawd-buddy --wave ────────> TCP:44556 ──> wave animation

1. Claude Code hooks fire shell commands when events happen (prompt submitted, response done, permission needed).
2. The clawd-buddy --send / --wave / --prompt-start CLI connects to 127.0.0.1:44556 and sends a JSON action.
3. The running buddy process receives the signal and plays the animation. Incoming signals during an active animation are queued (FIFO, capped at three) so attention requests are never silently dropped.

Signal protocol

The buddy listens on a TCP socket (default port 44556). Send a JSON payload to trigger actions:

{"action": "celebrate"}

{"action": "wave"}

{"action": "prompt_start", "session_id": "abc-123"}

The prompt_start action is the wire-once handler for a Claude Code prompt: the running buddy greets when it sees a new session_id (or when none is supplied and there has been no recent activity) and starts the thinking animation either way.

The status action is the only one that elicits a response — the buddy writes a JSON snapshot back on the same socket before closing:

$ clawd-buddy --status
{
  "version": "0.1.21",
  "pid": 12345,
  "port": 44556,
  "mode": "idle",
  "queue_depth": 0,
  "last_session_id": "abc-123",
  "last_action": "wave",

  }
}

reduce_motion, volume, and quiet_hours were added in v0.1.15; the reminder block was added in v0.1.16; reminder.anchor (the daily schedule start time) was added in v0.1.18; cups_today, today_date, and recent_days (the M4.1 drinking history) in v0.1.19; the pomodoro and http blocks in v0.1.20. Both quiet_hours keys are null when their respective window is disabled; reminder.seconds_until_next is null when the reminder is off and 0 when an alarm is firing; pomodoro.remaining_seconds is null when no cycle is running. The workspace block (v0.1.21) reports null label/ts until the first labelled signal arrives.

This is the recommended "is the buddy alive?" probe — exit code 1 plus a stderr message when no buddy is listening, exit code 0 with JSON on stdout otherwise.

You can send signals from any language:

import socket, json
s = socket.socket()
s.connect(("127.0.0.1", 44556))
s.sendall(json.dumps({"action": "celebrate"}).encode())
s.close()

echo '{"action": "wave"}' | nc localhost 44556

Or, with the HTTP webhook enabled (--http-port 8787), from anything that can speak HTTP — no socket code required:

curl -X POST localhost:8787/signal -d '{"action": "celebrate"}'

Single instance

Only one buddy can run at a time. If you launch clawd-buddy while one is already running, it sends a signal to the existing instance and exits.

System tray

The buddy adds a system tray icon with a right-click menu:

• Test Celebration — trigger the celebrate animation
• Bring to Front — re-assert always-on-top (recovers z-order)
• Theme — pick one of the 8 themes (current one is checked)
• Sound — pick a notification sound pack (Off, Fanfare, Chime, Retro, Minimal). Selecting a pack plays a preview immediately; the choice is persisted in config.json.
  • Volume — discrete steps 0% / 25% / 50% / 75% / 100%. Selecting a step previews the celebrate sound at the new level.
  • Quiet Hours — Off or a preset night window (e.g. 23:00 – 08:00). Inside the window all notification sounds are muted; animations still play.
• Reduce Motion — accessibility toggle. When checked, the buddy stops bobbing, swinging limbs, and spawning confetti; the colored attention border and sounds remain.
• Water Reminder — toggle the water-drinking reminder. Detailed config (interval, sound, quiet hours) lives in About… → Reminders.
• I drank water — appears only while a reminder is firing. Same effect as pressing Space when the alarm is active: dismiss the current alarm. The next scheduled slot still fires on time.
• Stop Pomodoro — appears only while a pomodoro cycle is running. Ends the cycle (same as clawd-buddy --pomodoro-stop).
• Workspace Badge — toggle the multi-session workspace badge (default on; it only renders once a second workspace signals anyway). Recording continues while hidden, so re-enabling shows current data.
• Clawd Buddy vX.Y.Z — informational version label (disabled)
• About… — open a tabbed dialog: About (version / repo / author) and Reminders (edit interval, sound, and quiet hours; live countdown; "Drank now" button).
• Quit — close the buddy

Autostart

clawd-buddy --startup registers the buddy to launch at login. clawd-buddy --no-startup removes it.

• Windows: Places a VBS launcher in %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\. Starts with a hidden console window.
• Linux: Creates a .desktop file in ~/.config/autostart/. Uses the XDG autostart standard supported by GNOME, KDE, XFCE, and others.

• Wide smile
• Both arms waving up
• Legs kicking
• Confetti burst (40 particles with gravity and drag)

• Pulsing cyan border around the body
• Silent (audio is intentionally deferred to a later milestone)
• Duration: ~1.8 seconds
• Per-session de-duplication via Claude Code's session_id

Thinking (between UserPromptSubmit and Stop)

• Slow, calm bobbing
• Pupils sweep upward and side-to-side (a "considering" pose)
• Three small pulsing dots float above the head
• Soft purple border, gentler pulse than the other states
• Silent
• Holds indefinitely until Stop arrives (with a 10-minute safety cap in case the assistant crashes or the network drops)

Reactions are queued while another animation is playing — up to three pending events play back in the order they arrived.

Speech bubble (any tool, via --message)

• Triggered by clawd-buddy --message "TEXT"
• Rounded bubble above the buddy's head with a small downward tail
• Theme-coloured (uses the active theme's screen background + body border + text colour)
• Word-wrapped to at most two lines, anything longer is truncated with an ellipsis
• Auto-dismisses after 3 seconds; sending a new message replaces the current one immediately
• Independent of the buddy's mode — bubbles coexist with idle, thinking, greeting, celebrate, and wave animations
• Silent (the visual is the whole point)

--message is the generic display surface — a script, CI job, or any other tool can use it to tell you something without writing its own notification UI:

clawd-buddy --message "tests green"
clawd-buddy --message "deploy starting…"
clawd-buddy --message ""              # dismiss any current bubble

Configuration

Custom port

If port 44556 is taken, use a different one:

clawd-buddy --port 55000

Update your hooks to match:

"command": "clawd-buddy --send done --port 55000"

Disable always-on-top

clawd-buddy --no-topmost

Troubleshooting

Buddy doesn't appear

• Windows: Make sure no other process is using port 44556: netstat -ano | findstr 44556
• Linux: Requires an X11 session. If you're on Wayland, the buddy forces SDL_VIDEODRIVER=x11 via XWayland. If it still doesn't appear, try clawd-buddy --fg to see errors in the terminal.
• macOS: Not yet supported.

Hook doesn't trigger the buddy

• Make sure the buddy is running (clawd-buddy in a terminal or via --startup).
• Test manually: clawd-buddy --send test — if this says "No buddy on port 44556", the buddy isn't running.
• Check that clawd-buddy is on your PATH: where clawd-buddy (Windows) / which clawd-buddy (Linux)

Multiple buddies / port conflict

• The buddy uses a lock socket on port 44557 (main port + 1) to prevent duplicates.
• Windows: taskkill /F /IM clawd-buddy.exe
• Linux: pkill -f clawd-buddy

Startup not working

Windows:

• Verify the VBS file exists: dir "%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\clawd-buddy*"
• Re-run clawd-buddy --startup to regenerate it.

Linux:

• Verify the desktop file exists: ls ~/.config/autostart/clawd-buddy.desktop
• Re-run clawd-buddy --startup to regenerate it.
• Make sure clawd-buddy is on your PATH: which clawd-buddy

Linux: window has a visible background

On Linux, color-key transparency is not available. The buddy renders on a themed background that matches whichever of the 8 themes you choose. Pick a light theme (light, solarized, sunset) on light panels/docks, or a dark one (dark, dracula, monokai, nord, gruvbox) on dark ones to blend in.
