# Price Drop Watcher

> Name your price. Hear back only when it drops.

- Category: Shopping
- Schedule: Daily, 9:00 AM
- Works with: Grok Bot, Muse, Dots
- Setup time: 1 minute
- Version: 1.0.0 (updated 2026-10-31)
- Cost: light

## What it does

Paste a product link and the price you'd pay. Price Drop Watcher checks the actual product page, not a cached search result, and confirms it's the same size, colour, condition, and seller before it tells you anything. Most days it stays quiet. When the price hits your number or an item comes back in stock, you get one short note with the link. It never adds to cart or buys.

## What you get

- A watchlist with starting price and date
- Alerts only when the price hits your target or drops past your threshold
- Back-in-stock alerts
- Variant, seller, and condition checked before alerting
- Direct product links

## Data it uses

- Web (product pages)

## Safety

- Writes or sends: Read-only. Never adds to cart or purchases.
- Reads: Public product pages you list (price and stock only)
- Cost: Low to medium: one run a day (~30 a month), one page check per watched product.
- Warning: It never adds to cart or buys anything.
- Warning: Some stores block automated page reads; those items show as 'couldn't check' rather than a wrong price.
- Warning: Prices can change between the alert and checkout.

### Grok Bot (verified)

1. Copy skills/price-drop-watcher/SKILL.md (the whole file, including the --- header).
2. Open a one-to-one chat with your Grok Bot and paste the prompt below, with the file where it says.
3. Try it once now: "Run Price Drop Watcher."
4. The routine shows in the Bot's info pane (click the Bot's name in the chat header) under Routines, where you can pause or edit it.

Note: Skills and routines are saved by asking the Bot; no settings to dig through.

### Muse (partially-verified)

1. Copy skills/price-drop-watcher/SKILL.md.
2. Open Muse and paste the prompt below with the file where it says.
3. Try it: "Run Price Drop Watcher." Muse has no skill install for outside skills, so it follows the pasted instructions.
4. Ask Muse to make it a recurring task every day at 9:00 AM. It then shows under the Assistant icon > Upcoming.
5. Muse Code (developer CLI): unzip downloads/price-drop-watcher.zip, run `muse skills validate ./price-drop-watcher` then `muse skills install ./price-drop-watcher --scope user`. Optional: add the BotPlaza connector (https://botplaza.lol/api/mcp) under mcpServers in ~/.config/muse/settings.json.

Note: Recurring tasks and Muse Code skill install are documented by Meta. Installing outside skills in the Muse app is not.

### Dots (partially-verified)

1. Copy skills/price-drop-watcher/SKILL.md.
2. Paste the prompt below into your dot's conversation in ChatGPT, with the file where it says.
3. Wait for the dot to confirm the schedule, time zone and end date.
4. Optional: in ChatGPT, Plugins > + > Add custom MCP server with https://botplaza.lol/api/mcp (no authentication). Dots can use installed plugins, but OpenAI hasn't said whether that includes custom ones.
5. Business, Enterprise, Healthcare and Edu workspaces can also upload downloads/price-drop-watcher.zip under Plugins > Skills > Create > Upload from your computer.

Note: Dots are available on ChatGPT Pro, Business Premium and Enterprise, and are still rolling out. Pasting instructions in and scheduled check-ins are documented.
