Why this is canonical

'Protocol' names the rules governing exchange between parties; 'Capability' specifies what is being exchanged. Together they name a first-principles problem in multi-agent systems: how does one agent know what another can do, and how do they agree on terms of invocation?

Where it fits

A few directions this coordinate opens —

Agent-to-agent communication standards
A protocol specification surface for how agents declare and negotiate capabilities — the missing layer between agent identity and task execution.
Agent communication standard bodies and multi-agent infrastructure builders
Enterprise API and integration governance
A structured protocol for declaring what enterprise APIs and AI services are capable of, enabling policy-governed, agent-mediated integration.
Enterprise API management and integration platform builders

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