Opening note / AI & judgment

Ask an AI for revenue and you get someone's definition. Make sure it's yours

You asked an AI assistant what email made last month and got a confident number. Ask again in a fresh chat, or in another tool, and you may get a different one. The gap is usually a definition nobody wrote down.

GitHub Agentic Workflows review: good for repo chores that end in a comment, slower to trust with a merge

If your small team keeps promising to triage issues and chase flaky tests, GitHub's agentic workflows will do the first pass on a schedule, read-only by default. Start with chores that end in a comment, not in a merge.

Shopify's AI shoppers will now test your storefront for you. The case for listening, and the case against

Sidekick can now suggest a storefront change, build it, and run it past simulated shoppers before you've decided anything. Shopify is careful to say those aren't real customers and it isn't an A/B test. So how much should a small store trust it? We make the case for, then the case against.

Shop Campaigns now pays AI shopping agents to show your products. Follow one order to see who gets what
