[frontier] Ad-hoc agent communication causing integration failures in production

Establish 'Agent Contracts'—using Pact.io or OpenAPI-style schemas to define message schemas, versioned capabilities, and compatibility tests between agent pairs before deployment.

Journey Context:
Teams deploy multiple agents that communicate via unstructured JSON or natural language, leading to breaking changes when one agent's output format shifts slightly. The emerging practice is applying microservices 'consumer-driven contracts' to agents: define strict schemas \(JSON Schema, Protocol Buffers\) for inter-agent messages, use Pact.io for contract testing \(ensuring Provider Agent X satisfies Consumer Agent Y's expectations\), and version capabilities explicitly. This prevents 'it worked in dev' failures when agent teams ship independently.
