Yesterday, we shared in our Community Forum what you should be doing to secure your apps and maintain merchant trust.

These are the steps you should take now:

@DorianDevelops Whatever makes the job the right and cheap way 😉
My case is always Opus. I just play with low, mid, and high effort.

The query, the pair script and the full test protocol:

Black Friday is Nov 27. Six weeks.

Your Shopify discounts will do exactly what their combination settings say. Nobody reads those settings as a set.

That's how a cart drawer promises free shipping and the checkout charges for it.

[Jean Manzo @jdevmanzo]

Before launch:

Pull every active and scheduled discount with discountNodes + combinesWith. Build the pair grid.

Test under, over, and over-then-under the threshold. Live checkout, BFCM set eligible only for a staff test customer.

The Google AI Mode side (on by default) and how to turn direct checkout off:

Shopify's AI commerce numbers, minus the hype.

Q1 2026: AI-driven traffic to Shopify stores up 8x YoY, orders from AI searches up nearly 13x.
Q2 2026: both tripled YoY.

Those are multipliers. Shopify doesn't publish the share. Part of the drop is math: the base got bigger.

Then go through Sales channels > Agentic, channel by channel.

ChatGPT: checkout runs on your store in an in-app browser. No direct checkout toggle.
Google, Copilot, Meta: direct checkout is its own setting.

Title or category in metafields? That's what Catalog Mapping is for.

All five, with the Liquid and JS:

Mobile: about 70% of ecommerce traffic, 2% conversion.
Desktop: 3.4%.

"Put the buy button, delivery date and Shop Pay above the fold" doesn't survive a phone. The first screen is the photo.

Fixes 4 and 5:

Variant buttons over dropdowns. Sold out values get a class, not the disabled attribute, so the tap still says why.

First product image: loading eager + fetchpriority high. One image. Not the whole gallery.

I’ve lived through 3 earthquakes (Venezuela, Colombia, and Panama) so far this year. I’m traumatized now. Every movement I feel triggers survivor mode so badly that I suffer a weird pain in my neck for hours. The last one was Panama, and I felt it here in Medellín

How I let coding agents run unattended without handing them my machine.

No route out. No keys to the house. An undo it can't reach.

The one I'd steal even if you never use ralph-sandbox: the QA agent has no edit tools. Finding and fixing in one pass is how a loop lies to itself.
