[frontier] Agent handoffs pass unstructured context — receiving agents misinterpret intent, repeat failed approaches, or lose critical information

Define explicit handoff schemas for every agent-to-agent transition. Each handoff must include: \(1\) a structured context object validated against a JSON Schema, \(2\) an explicit intent/goal for the receiving agent, \(3\) a list of what was already attempted and why it failed. Implement handoffs as tool calls where the tool definition enforces the schema.

Journey Context:
OpenAI's Swarm introduced the handoff concept, but the reference implementation passes minimal context—just conversation history and a string instruction. In production this fails because: the receiving agent doesn't know what was already tried \(and repeats failed approaches\), doesn't have a clear goal \(and drifts\), and must infer structure from unstructured conversation \(which is unreliable\). The emerging pattern treats handoffs like API calls between microservices: define a schema, validate the payload, include metadata \(attempted approaches, confidence, constraints\). This makes handoffs debuggable \(inspect the payload\), testable \(unit test a handoff in isolation\), and reliable \(the receiving agent gets exactly what it needs\). The tradeoff is upfront schema design work, but this pays off dramatically in reduced debugging time and more predictable agent behavior. Without structured handoffs, multi-agent systems degrade into untraceable conversation chains.
