They remember things between requests. They run on your laptop, in CI, or in the cloud. Every step is a terminal command. So your coding agent can do all of it: create the… https://apievangelist.com/2026/10/15/the-wires-are-crossed-slop-for-humans-structure-for-agents/ veille techno-1792130487226046 Thu, 15 Oct 2026 00:00:00 +0000 I think the wires are crossed in how we are using agents right now. The thing agents are actually good at, and the thing they actually need, is structured, machine-readable content written for other machines.

For the last year the Kin Score has measured two things about an API provider: what they publish, and how ready that is for agents.
