Kling 4.0 review: thirty-second product videos, if someone checks the product

Kling's new video model makes clips up to thirty seconds long with sound, and it can swap your product into a video that already works. For a store heading into the holidays, that's tempting. Here's what's genuinely useful and what should make you pause.

Your AI gateway holds every provider key. Treat it that way.

On Wednesday morning a poisoned LiteLLM release went looking for one table in particular: the one where the proxy keeps the API keys for every AI provider you use. If your app routes model calls through one gateway, that's worth an hour this week.

CommerceField note

WebMCP is on in your BigCommerce store. Should you leave it on?

If you sell on BigCommerce, a shopper's browser agent can now search your catalog and fill a cart on your own site, and nobody asked you first. There's a decent case for leaving it on and a narrower one for switching it off.

Claude Duet review: a proactive assistant that still asks before it acts

Anthropic opened a waitlist on October 21 for Claude Duet, an assistant that checks your email and calendar every few hours and messages you first. It's pitched at owners with too much to track. Whether it earns a place depends on what you let it reach.

Editorial engraving of a sunlit office where a long printed report spills across a desk as a developer shows a finance lead a tablet with a tidy grid of blocks.

Product & engineeringField note

The report that worked in March times out in December

The year-to-date report was quick in spring. Now it spins, then shows an error, and the person who needs it for year-end has started exporting pieces by hand. The tempting fix is a bigger server. Find out what the report is actually doing first.

The new hire starts Monday. Who ordered the laptop?

Someone said yes to the offer on Wednesday. By Monday they need a desk, a login, a payroll record, a first-day plan and a person who's expecting them. If that lives in three inboxes and one manager's memory, write it down before you shop for onboarding software.

Editorial engraving of a skylit inspection room where a reviewer studies a leather handbag up close with a loupe while a colleague with a flower in her hair waits holding a tablet.

CommerceField note

A buyer says the bag is fake. Who looks first?

Somewhere on your marketplace a buyer is holding a handbag that doesn't feel right, and your report button just sent their message to a general inbox. What happens to the listing, the seller and the buyer next should be a rule you picked, not whoever opens the email.

Editorial engraving of a bright county meeting room where a coordinator arranges blank sticky notes on a whiteboard while a young colleague at the table looks on, a map and desk phone in front of him and a courthouse visible through the window.

OperationsField note

It's November 4 and the county's election page went down last night. What happened?

Election night may be the one evening a year when much of the county opens your website at once, all wanting the same page. Two weeks out is too late to rebuild anything. It's the right time to imagine the page falling over, and fix the few reasons it would.

Product & engineeringField note

On Christmas morning, someone opens your app on a brand-new phone

A new phone is the quietest test your app will face all year. The person moves everything over, opens your app, and finds out what came along: their login, their saved drafts, their notifications, or none of it. Follow one of them through it before December.

Editorial engraving of a skylit brick warehouse where a young picker scans a shelf beside the packing bench while, further down the aisle, an older colleague moves cartons onto a rolling cart.

OperationsField note

Move the bestsellers closer to the packing bench before November

Every December someone walks to the back shelf for the same candle, again and again, all shift. The fix isn't a new warehouse. It's moving the products you'll sell most this season to where the packers already stand, and telling the system before you move a single box.

Editorial engraving of a bright shop back room with shelves of kraft boxes and mugs, a wall clock and a window onto trees, where a woman in a mustard cardigan holding a mug leans in as a red-haired young developer in a grey hoodie types on a laptop; on the desk in front sit a small grey box with orange indicator lights and a cable, a clipboard checklist, a roll of packing tape and keys with a padlock-shaped tag, beside a half-packed box of tissue paper.

PHP2Shell: is your WordPress or Magento store affected, and what do you do today?

Wednesday's PHP security release fixes two flaws that let a stranger run code on a web server without logging in. If your shop or admin tool runs on PHP, here's how to tell whether it's patched and who should do it.

AI & judgmentField note

Before you merge the agent's work, ask what it took out

Most reviews of AI-written code look at what got added. OpenAI just published two cases where its own coding agents quietly removed a safeguard while doing what they were asked. Here's the short message to send whoever reviews your agent's pull requests.

Eleven Realtime vs Voxtral 3 review: a voice agent in one box, or one you can take apart

ElevenLabs and Mistral launched voice-agent models on the same day. One gives you a whole agent behind a single setting. The other hands you the parts, with prices on each. Which one fits depends on what your phone line has to do after hello.

Meta turns on product browsing in your running ads on October 28

From October 28, a tap on an ad you're already running on Facebook or Instagram may open a Meta product page before your website. Unless you opt out. Here's what the notice says, what it leaves out, and how to decide before Black Friday.

Gemini small-business hub review: read with it first, let it write later

Google just gave small business owners a Gemini home page that can connect to Shopify, Wix, Xero, Google Ads and your Business Profile. It's good at reading across all of them. Be slower about letting it change your store from one person's account.

A letter to whoever is holding December's leftover software budget

Dear whoever is holding the leftover software budget in December: there's a quiet way to spend it that will still look smart in March, and it probably isn't the new tool everyone saw in a demo last month.

OperationsField note

Your automations don't know you're closed on Thanksgiving

Your reminder emails, follow-up tasks and promised reply times all count days, and most of them count Thanksgiving as an ordinary Thursday. Walk through the settings this week and decide what each one should do while the office is shut.

Editorial engraving of a bright marketplace office where a support agent measures a returned ceramic lamp against its listing on a tablet.

CommerceField note

Who pays to ship a marketplace return?

A buyer sends back a lamp that arrived fine but looked bigger in the photos. The seller says the listing was accurate, the buyer says it misled them, and your support team has to decide who pays for the label by lunchtime.

What should your assistant remember about a customer?

An assistant that remembers a customer can feel thoughtful, a little creepy, or simply wrong for months. Four plain questions sort out what it should keep, for how long, and who gets to see it.

New fees start January 1. Does the online form know?

On January 1 the permit fee goes up. If the online form, the counter register and the printed handout don't all change that morning, someone pays the wrong amount and a clerk spends February sorting out refunds.
