+# WhatsApp Notification Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a WhatsApp notification to the dashcam transfer script that sends a summary to admin Eddy after each transfer.
+
+**Architecture:** A single `send_whatsapp_notification()` function is added to `dashcam-transfer.py`. It POSTs to the local wwebjs-api (running on Mac Mini via Tailscale) using stdlib `urllib.request`. Failures are logged but never crash the script.
+
+**Tech Stack:** Python 3 stdlib (`urllib.request`, `json`), wwebjs-api REST API
+
+---
+
+### Task 1: Add WhatsApp notification to dashcam-transfer.py
+
+**Files:**
+- Modify: `dashcam-transfer.py:3` (add imports)
+- Modify: `dashcam-transfer.py:189-191` (add notification call)
+
+- [ ] **Step 1: Add imports**
+
+Add `import json` and `import urllib.request` after the existing stdlib imports.
+
+- [ ] **Step 2: Add `send_whatsapp_notification()` function**
+
+Insert before `parse_args()` (after `ensure_free_space`):
+
+```python
+WHATSAPP_API = "http://100.97.199.84:3000/client/sendMessage/EdGpt"
+WHATSAPP_CHAT = "31620248011@c.us"
+
+
+def send_whatsapp_notification(ok, errors):
+    status = "geen fouten" if errors == 0 else f"{errors} fout(en)"
+    body = f"Dashcam transfer voltooid: {ok} bestanden overgezet, {status}"
+    payload = {"chatId": WHATSAPP_CHAT, "content": body, "contentType": "string"}
+    try:
+        data = json.dumps(payload).encode()
+        req = urllib.request.Request(WHATSAPP_API, data=data, headers={"Content-Type": "application/json"})
+        urllib.request.urlopen(req, timeout=10)
+        logging.info("WhatsApp notificatie verstuurd")
+    except Exception as e:
+        logging.warning("WhatsApp notificatie mislukt: %s", e)
+```
+
+- [ ] **Step 3: Call notification at end of `main()`**
+
+Replace:
+```python
+    logging.info(
+        "Transfer voltooid: %d ok, %d fouten", ok, errors
+    )
+```
+
+With:
+```python
+    logging.info("Transfer voltooid: %d ok, %d fouten", ok, errors)
+    send_whatsapp_notification(ok, errors)
+```
+
+- [ ] **Step 4: Verify the script parses correctly**
+
+Run: `python3 -c "import ast; ast.parse(open('dashcam-transfer.py').read()); print('OK')"`
+Expected: `OK`
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add dashcam-transfer.py
+git commit -m "feat: stuur WhatsApp notificatie na dashcam transfer"
+```
