Full Article

Agent systems have mostly been built around a simple assumption: the model may decide what to do next, but the surrounding execution structure is designed by the developer. We give the model tools, define a loop, manage context, constrain permissions, record traces, add retries, and sometimes insert human approval. The model acts, but the system decides the shape of action. That assumption is starting to weaken. A new pattern is emerging across several parts of the agent stack.
