The protocol-layer coordinate for structured cognitive AI communication.

A cross-cutting position naming the protocol layer for cognitive AI — the standards and structured communication formats by which cognitive agents exchange reasoning, context, and intent.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

'Cognitive protocol' names the emerging layer of structured communication between intelligent agents — not just data transfer, but the exchange of reasoning states, context windows, and cognitive representations. On .ai, this is the canonical coordinate for any platform formalizing how cognitive AI systems talk to each other.

Where it fits

A few directions this coordinate opens —

Agent interoperability standard
The protocol layer enabling cognitive agents from different vendors and architectures to share reasoning context, goals, and state.
Agent interoperability standard builders, AI protocol consortia, open-source agent framework developers
Cognitive API design
The product identity for platforms defining how AI applications communicate cognitive state — prompt protocols, reasoning-exchange formats, cognitive context APIs.
AI API platform builders, LLM gateway companies, cognitive middleware developers

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
