Daily competitor price and promo watch for any website

Every weekday at 7am, watch my competitors' prices so I never miss a change. I keep a watchlist of competitor product and pricing page URLs in a Google Sheet, along with the most recent price, promo, and stock snapshot for each one, and I want you to read that list at the start of every run.

Read the watchlist with Get Values in Google Sheets. Each row should give you a competitor name, the page URL, and the last logged price, discount or promo, and stock status, so you have a baseline to compare today's numbers against.

For each URL, dispatch a Browser Use agent task with Run Agent Task, then poll Get Session until it finishes. Tell the agent to open the page and extract the current price, any discount or promo banner, and the stock status. Browser Use is the right tool here because it can read prices on sites that have no public API and that render prices with JavaScript, and it copes with wildly different page layouts from one competitor to the next.

Compare each result against the most recent snapshot already logged in the Sheet. Then append today's prices for every tracked page as a new row with Append Values, so the spreadsheet becomes a running price history I can chart or review later.

Post a Slack digest with Send a Message that highlights only the meaningful moves: price drops, price increases, and new promotions. Show the old and new value for each change so I can see the delta at a glance. Skip any page that did not change so the channel stays quiet on slow days, and if nothing changed across the whole watchlist, say so in a single short line rather than listing every unchanged page.

Use your judgement about what counts as a meaningful change before writing the summary. A rounding difference or a reworded banner is not worth flagging, but a real price move or a genuinely new promotion is. This is an agent workflow precisely because it has to interpret pages that all look different and decide what actually matters.
