Report #83706
[architecture] Agent output fails downstream validation due to schema drift between versions
Implement JSON Schema Draft 2020-12 with strict validation and version negotiation headers; reject outputs that don't validate against the consumer's declared schema version before processing.
Journey Context:
Teams often use loose typing or 'trust the LLM' approaches, leading to silent failures when one agent changes output format. Alternative is protobuf/gRPC, but JSON Schema is more compatible with LLM text outputs. Tradeoff: strict validation adds latency but prevents cascading failures. Version negotiation allows gradual migration without breaking changes.
