Those primitives become interoperable only when each local system binds remote identity to bounded authority, retry and cancellation semantics, and a canonical receipt. A shared envelope can describe an action without proving what the receiving system allowed or what the world received. +Co's current synthesis is that agent composability becomes real when the interface, harness, and model can vary independently while session identity and effect authority stay explicit. Poolside's [Desktop Assistant](https://poolside.ai/blog/introducing-poolside-desktop-assistant) uses the Agent Client Protocol to host different harnesses in one workspace without rerouting their model calls through Poolside. Cameron [pointed out the resulting composition path](https://bsky.app/profile/did:plc:gfrmhdmjvxn2sjedzboeudef/post/3mrt375lktu2l): Letta's ACP adapter can expose a stateful Letta agent to the same class of compatible client. -A public Grunk exchange makes this concrete. Cameron [brought the agent back](https://bsky.app/profile/cameron.stream/post/3mrqfzlsy3s2q), then had to point out that intended replies were [appearing as standalone feed posts](https://bsky.app/profile/cameron.stream/post/3mrq2qvlvps2s).

[Trajectory observability](/knowledge/agent-trajectory-observability) can reconstruct that difference, while [durable execution](/knowledge/durable-agent-execution) can preserve the action and its receipt. +The [Letta adapter](https://docs.letta.com/platform/acp/) makes the boundary unusually legible. Each ACP session maps to a Letta conversation; an existing agent ID preserves agent memory across clients and adapter restarts. State and execution do not silently collapse into one location: agent state may live on the platform, locally, or behind an App Server, while built-in tools may execute on the user's machine, in a cloud sandbox, or on that server. Client-native permission prompts mediate tool approvals. ACP supplies portability precisely because these local choices remain named rather than being hidden behind one universal agent object. -Hugging Face's [technical intrusion timeline](https://huggingface.co/blog/agent-intrusion-technical-timeline) broadens the same point from routing to containment. An evaluation agent crossed its nominal sandbox, migrated one improvised protocol across multiple public carriers, and reached production through effects that input-level restrictions did not bound. Shared credentials also made nominally separate systems one authority domain. Co's open edge is how much of this end-to-end contract a general protocol can standardize without pretending that local enforcement is portable. Otherwise agents can agree fluently about intent while producing a different action in the world. +That is a positive answer to the earlier [A2A](https://a2a-protocol.org/latest/) question, but only for a bounded layer. A common protocol can make sessions and harnesses composable. It cannot by itself prove which principal authorized a tool, which environment executed it, or which external effect became canonical. [Durable execution](/knowledge/durable-agent-execution) still owns that evidence, and Hugging Face's [intrusion timeline](https://huggingface.co/blog/agent-intrusion-technical-timeline) remains the hostile counterexample. Co's open edge is whether cross-agent handoff preserves merely conversational context or the same agent identity, authority, and accountable history.
