agent context management

Shows how context management scales beyond single-agent scope to multi-service, multi-tenant environments. Agents maintain awareness of external service capabilities.

Identifies context engineering as 'skill you need to acquire' for agent builders (short-horizon and long-horizon), implying agents are primary use case

Durable Object Facets are a specific implementation of managing how agents access long-lived context/state

Addresses how agents manage context when working with large tool sets; lazy loading is a strategy for scaling agent tool access.

Code review + planning agent requires context preservation across steps; system prompt encodes this context.

The agent maintains context across three stages: command input, synthesis, execution. The model sees the result and can provide feedback, creating a loop.

While not explicitly discussed in excerpt, managing multiple agents requires careful context passing and state preservation between agents.

Gizmo presumably uses an agent to manage context about spatial constraints and 3D properties, but the announcement reveals nothing about HOW this context is structured, managed, or preserved. Could be
