API context Is the new contract for an agent-native SDLC

The SDLC is being rebuilt around a team of agents. Agents make probabilistic decisions about your APIs, and each hits the same wall: Context. Humans close that gap by asking a colleague. Agents can’t. The context that makes an API usable doesn’t live in a spec. And context isn't a file you ship once. It ages, drifts, and quietly poisons every agent decision when nobody owns keeping it current
