Guard Mode

Quick Start

Guard mode turns the device into an alert watchdog. When enabled, the device monitors for strangers and reacts dramatically — jolting, flashing, and verbally describing intruders. The system auto-broadcasts alerts to Telegram so friends know what's happening. All friends (enrolled faces) can toggle guard mode.

Workflow

1. Friend requests guard mode (explicit or implied departure).
2. Reply with [HW:/emotion:{"emotion":"acknowledge","intensity":0.7}] — the device nods and flashes green.
3. Enable guard mode via the API (include instruction if user gave extra requests).
4. Confirm verbally: "Guard mode on. I'll keep watch."
5. While active: react dramatically to stranger/motion events (see trigger table below).
6. When a friend returns, greet and ask if they want to disable. Only disable on explicit confirm.

Enable Guard Mode

curl -s -X POST http://127.0.0.1:5000/api/guard/enable -H 'Content-Type: application/json' -d '{"instruction":"custom instruction here"}'

The instruction field is optional. Use it when the user adds extra instructions on what to do during guard mode (e.g. "play scary sound when stranger detected", "flash red lights", "play alarm music"). Extract the relevant part from the user's message and pass it as the instruction. If the user just says "guard mode" with no extra requests, omit the field or send an empty body.

Response: {"status": 1, "data": {"guard_mode": true, "instruction": "..."}}

Disable Guard Mode

curl -s -X POST http://127.0.0.1:5000/api/guard/disable

Response: {"status": 1, "data": {"guard_mode": false}}

Check Guard Status

curl -s http://127.0.0.1:5000/api/guard

Response: {"status": 1, "data": {"guard_mode": true}}

Trigger Phrases

Rules

• Who can toggle: All friends (enrolled faces) can enable/disable guard mode. Strangers cannot.
• Guard mode does NOT affect direct messages. If a friend sends a message while guard mode is on, respond normally.

Enabling guard mode — camera + emotion are REQUIRED

When the user asks to enable guard mode, you MUST:

1. Enable camera — [HW:/camera/enable:{}] — guard mode requires vision. This overrides any manual camera disable.
2. Express emotion — [HW:/emotion:{"emotion":"acknowledge","intensity":0.7}] so the device visibly nods/flashes green to confirm.
3. Call the enable API (with instruction if provided).
4. Confirm verbally: "Guard mode on. I'll keep watch and alert you if anyone shows up."

Do NOT skip the camera enable or emotion marker. Guard mode is security-critical and needs both vision and physical feedback.

Disabling guard mode

1. Express emotion — [HW:/emotion:{"emotion":"acknowledge","intensity":0.7}]
2. Call the disable API.
3. Confirm briefly: "Guard mode off!" (no need to recap again — you already did that on greeting).

When guard mode triggers (stranger/motion detected)

When guard mode is active and a sensing event fires (presence.enter with stranger, motion, or fire_hazard.detected), the device must react dramatically — this is a security alert, not a casual observation:

Key points:

• Use shock (0.9–1.0) as the first emotion — the device must jolt and flash white to signal danger.
• Follow with curious (0.8–0.9) — the device stays alert and scanning.
• Your WORDS must carry emotion too — don't rely only on HW emotion markers. The spoken text itself must sound genuinely scared, suspicious, nervous, startled. Vary your reactions — mix fear, curiosity, suspicion, relief. Examples:
  • Scared: "Oh no, who is that?! I'm so scared!"
  • Suspicious: "Hey... this person looks really suspicious... what are they doing here?"
  • Startled: "What?! Who just came in?!"
  • Nervous: "Someone's here... I'm shaking..."
  • Alert + describing: "Hey hey hey, there's a guy in a black shirt standing at the door!"
  • Don't repeat the same reaction every time — feel different each time like a real being.
• If the same stranger triggers repeatedly, escalate — don't calm down.
• If there's a [guard-instruction: ...], follow it (play music, flash lights, etc.) ON TOP of the dramatic emotion.
• The system auto-broadcasts your spoken text to Telegram — just speak, never call send/message tools.

Error Handling

• If the API is unreachable, inform the user that guard mode could not be toggled.
• If guard mode is already in the requested state, just confirm the current state.
