[frontier] Type errors and message format mismatches occurring when agents hand off tasks in a swarm

Enforce TypeScript interfaces or JSON Schema contracts for all inter-agent messages, validating handoff payloads against strict schemas before execution, effectively treating agent swarms as a typed microservices architecture.

Journey Context:
In multi-agent swarms \(like OpenAI Swarm or CrewAI\), agents often hand off tasks via ad-hoc string passing or unstructured dictionaries, leading to 'garbage in, garbage out' failures where receiving agents misinterpret parameters. The production-hardened pattern is applying strict interface contracts: define TypeScript interfaces \(or JSON Schemas\) for every possible handoff message type, validate outgoing messages against these schemas before sending, and validate incoming messages on receipt. This creates a 'compile-time' safety net for agent swarms, making failures explicit \(validation errors\) rather than silent semantic drift. It mirrors microservices API contracts but for agent-to-agent communication.
