Business notes on what to automate, plus the eCommerce field guide. These posts stay guides. The commercial offer — five families we build — lives on the AI Agents hub. This category URL is not that hub.
OpenAI's 11 February 2026 Codex experiment merged about 1,500 pull requests. AgentCore Harness, GA 17 June 2026, still defaults to 75 iterations and a 3,600-second timeout — the harness sets those bounds, not the model.
On 25 September 2026 AWS published an SES skill for the MCP Server. The example is verify an identity and send a first production email. It does not warm a dedicated IP or pick Essentials versus Pro.
On 25 September 2026 AWS published agent skills for End User Messaging and SES. A delivered US Rich RCS text segment lists at $0.01194. A rich card lists at $0.02949. Pick the channel before you pick the model.
RCS for Business shipped 31 March 2026. A US Rich text segment lists at $0.01194 on delivery. A rich card lists at $0.02949. CLI 2.35.12 is the first release with send-rcs-message.
A US 10DLC number lists at $1 a month, a regular campaign at $10, and company vetting at $41.50. SMS is the OTP and the RCS fallback. It is the wrong place to build the rich agent.
Since 1 July 2025 WhatsApp on AWS is billed per message. The AWS fee is $0.005 outbound and $0.001 inbound. India Authentication and Utility are $0.002. Meta's fee is extra.
Checkout for a shopping agent is your cart math behind a contract, not a prompt. ACP specifies five endpoints. UCP checkout is a select-merchant program. Pin the spec date. Idempotency stops the double order.
Last-click will not explain an order that started in ChatGPT or AI Mode. ACP has an affiliate_attribution field. It is not a reporting suite. On 25 September 2026 the honest status is still immature.
