Proactive Agent

Proactive Agent

Overview

Zoe can proactively reach out to users via push notifications. Notifications deep-link back into a chat session so the conversation continues naturally.

Endpoints

Schedule a one-shot nudge

POST /api/proactive/schedule
{
  "message": "Time to do your stretches!",
  "send_at": "2026-05-04T14:00:00Z",
  "user_id": "family-admin"   // optional — admin only
}
→ {"id": "<scheduled_id>", "user_id": "...", "send_at": "..."}

List pending scheduled nudges

GET /api/proactive/schedule
→ [{"id": ..., "message": ..., "send_at": ..., "fired": 0, ...}]

Cancel a scheduled nudge

DELETE /api/proactive/schedule/<scheduled_id>
→ {"cancelled": true}

Claim a pending notification (called by UI on tap)

POST /api/proactive/pending/<pending_id>
→ {"session_id": "<new_session_id>", "message": "..."}

Zoe Agent MCP Tool

Use the proactive_schedule MCP tool when the user asks to be notified at a specific future time. Example:

{
  "name": "proactive_schedule",
  "arguments": {
    "message": "Time for your 3pm stand-up!",
    "send_at": "2026-05-04T05:00:00Z"
  }
}

When to Use

• User says "remind me at 3pm to call the doctor"
• User says "notify me in 2 hours"
• User says "send me a message tomorrow morning at 8am"
• Any explicit future-notification request

Workflow

1. Parse the requested reminder message and target time.
2. Ask a clarifying question if the time, date, timezone, or recipient is ambiguous.
3. Use proactive_schedule or POST /api/proactive/schedule to create the nudge.
4. Confirm the scheduled message and when it will fire.
5. Use the list or cancel endpoints when the user asks to review or remove pending nudges.

Example

User: "Remind me tomorrow at 8am to put the bins out"

Steps:

• Parse the message as "put the bins out".
• Resolve "tomorrow at 8am" to an ISO timestamp in the user's timezone.
• Call proactive_schedule with the message and send_at.
• Respond with a short confirmation including the scheduled time.

Error Handling

• Ambiguous time: Ask for a specific time before scheduling.
• Past time: Ask for a future time instead of silently adjusting.
• Duplicate request: If a very similar pending nudge exists, mention it before creating another.
• API failure: Tell the user the notification could not be scheduled and suggest retrying.

Implementation Notes

• Scheduled nudges must use Zoe's configured production persistence path; do not introduce SQLite-only storage for live reminders.
• Quiet hours (22:00–07:00 server local) suppress non-forced notifications.
• Tapping a push notification creates a fresh chat session pre-seeded with the notification message, enabling a natural follow-up conversation.
