[architecture] What schema contract should agents use when they are not built by the same team?

Publish and version an OpenAPI-style contract for agent-to-agent messages: required fields, typed slots, enum values for intent labels, and a \`confidence\` scalar. Consumers should reject messages that violate the contract rather than trying to 'parse around' the mismatch, and producers should bump the version for any breaking change.

Journey Context:
Ad-hoc prompt engineering lets every agent invent its own output shape, which becomes undeclared technical debt. A shared schema is the only way to compose agents safely. People worry that strict schemas stifle agent creativity, but agents are not creative about wire formats—creativity belongs in the payload, not the envelope. OpenAPI/JSON Schema is the right lingua franca because tooling \(validation, code generation, documentation\) already exists. The tradeoff is upfront coordination cost versus downstream integration breakage.
