Manage Timers

Own the lifecycle of timer and pomodoro holograms: create them, cancel them, and handle the control events they emit.

Start a countdown

1. Parse the duration to seconds (e.g. "5 minutes" → 300; "an hour and a half" → 5400).
2. Call start_timer{duration_seconds, label?}. The server tracks ends_at_ms and returns a timer_ref plus a timer directive.

timer props (registry.json; durations in ms):

{ "widget_type": "timer",
  "transform": { "anchor": "head", "position": [-0.45,0.1,0.9], "billboard": true },
  "props": { "label": "Tea", "duration_ms": 300000, "remaining_ms": 300000,
             "state": "running", "mode": "countdown" },
  "interactions": ["tap","grab","resize" 

agent.speech: { "text": "Timer started for 5 minutes.", "final": true }

Pomodoro

Call start_pomodoro{task?} → a pomodoro widget cycling focus → short_break → … with completed_sessions tracking:

{ "widget_type": "pomodoro",
  "props": { "phase": "focus", "remaining_ms": 1500000, "focus_ms": 1500000,
             "break_ms": 300000, "state": "running", "task": "Write report" } }

Handle controls (client.interaction, protocol §5.11)

The widget emits events; react with holo.update (or stop_timer):

Event (name)	element	Your action
pause	pause_button	recompute remaining_ms, holo.update state:"paused"
resume	resume_button	set new ends_at, holo.update state:"running"
reset	reset_button	remaining_ms = duration_ms, state:"idle"
dismiss	close_button	stop_timer → holo.destroy

Completion

When remaining_ms hits 0, set state:"completed" and fire a notification_toast (via the system/notify path):

{ "widget_type": "notification_toast",
  "props": { "title": "Timer finished", "body": "Your 5-minute tea timer is done.",
             "severity": "success", "source": "Timer", "actions": [ { "id": "snooze", "label": "Snooze" } ] } }

Edge cases

• No duration given → clarify-intent ("how long?"). Don't default silently.
• "Cancel the timer" with multiple → cancel the most recent (last_timer_ref) or ask which; stop_timer{timer_ref} targets a specific one.
• Very long timers / alarms at a clock time → that's a set-reminders job, not a countdown.
• Stopwatch → mode:"stopwatch" counts up; omit a meaningful duration_ms.
