# JD Price Protection

Auto-apply price protection (价格保护) on all eligible JD.com orders via Chrome Browser Relay.

## Prerequisites

- Chrome with OpenClaw Browser Relay extension installed and connected (badge ON)
- User must be logged into JD.com in Chrome
- OpenClaw gateway running

## Usage

Run the script:

```bash
node <skill-dir>/scripts/price-protect.js
```

The script will:
1. Connect to Chrome via OpenClaw's CDP relay (auto-derives relay token from gateway config)
2. Navigate to `https://pcsitepp-fm.jd.com/` if needed
3. Click every "申请价保" button on the page
4. Reload and collect results (successes with refund amounts, failures with reasons)
5. Output JSON results

## Interpreting Results

```json
{
  "total": 11,
  "clicked": 11,
  "success": [{"name": "ANKER 140W充电线...", "amount": "6.00"}],
  "failed": [{"name": "KAMAN收纳盒...", "reason": "无差价"}]
}
```

- Only notify user if `success` array is non-empty (refunds obtained)
- If all items show "无差价", update state silently

## Scheduled Usage

Set up a cron job to run every ~8 hours. Example agent prompt:

> Run `node <skill-dir>/scripts/price-protect.js`. If Chrome relay is disconnected (error), skip silently. If refunds found, notify user. Otherwise update checkedAt silently.

## Troubleshooting

- **"No browser page available"**: Chrome relay disconnected. User must click Browser Relay toolbar icon.
- **"No gateway token found"**: Set `GATEWAY_TOKEN` env var or ensure `~/.openclaw/openclaw.json` has `gateway.auth.token`.
- **Timeout on clicks**: A popup may be blocking. Script presses Escape after each click to dismiss.

## How It Works

Derives the relay auth token via `HMAC-SHA256(gatewayToken, "openclaw-extension-relay-v1:<port>")`, connects Playwright to Chrome's CDP websocket, then uses `getByText('申请价保', {exact: true}).click()` to trigger each button.
