Report #47242

[architecture] Passing agent outputs downstream without structural validation causes cascading failures in multi-agent chains

Implement JSON Schema validation at agent boundaries; reject outputs that violate contracts before state mutation occurs

Journey Context:
Teams often rely on LLM 'good behavior' but face drift or prompt injection; strict schema validation is cheaper than downstream error recovery and prevents poisoned context from propagating
