Report #88137

[architecture] Breaking changes in agent output format cause downstream failures that are discovered at runtime rather than deployment time

Treat inter-agent boundaries as public APIs with OpenAPI/JSON Schema and semantic versioning; enforce compatibility checks in CI/CD

Journey Context:
Agent teams often treat internal boundaries as 'private implementation details', changing output formats without coordination. When Agent A v2 changes a field name, Agent B fails mysteriously in production. The fix is strict contract management: define OpenAPI or JSON Schema specifications for all inter-agent traffic, use semantic versioning \(major.minor.patch\), and enforce backward compatibility checks in CI/CD \(e.g., breaking change detection\). Consumers pin to major versions. This treats agents as microservices with explicit service boundaries, preventing 'works on my machine' integration failures.
