Vitamins due next week — unless they already subscribe. Predict the window, draft one reminder, never charge the card. Cart abandonment is 70.22%; that is not a refill rate.

Monday, the wholesale counter. An agent looks up their net, not the public product page. 3 signed-in roles keep the price book closed. No payment capture.

Human approval is a queue with order id and tool trace — not a prompt. The public worksheet uses a $75 refund ceiling above which a person must click Approve. Never auto-approve when the SLA expires.

Store-connected agents fail at secrets, PII, and payment tools — not at prompts. Support-shaped pilots tracked roughly 3× spend when a browser tool stayed on for lookup turns. Delete payment tools.

February 2026 server-side tool execution via AgentCore Gateway + Responses API cut median tool-round-trip latency ~180 ms → ~95 ms on a 12-tool SaaS CRM assistant by removing the client orchestration hop.
