Report #40732
[architecture] Schema drift in multi-agent chains causes silent data corruption downstream
Implement JSON Schema contracts with backward compatibility checks and validation gates that fail closed on mismatch, using 'additionalProperties: false' to catch unexpected fields
Journey Context:
Teams often skip explicit contracts, relying on 'duck typing' that breaks when one agent evolves outputs independently. Alternative integration testing only catches errors post-deployment. Schema validation at boundaries acts as circuit breakers, trading milliseconds of latency for prevention of cascading failures. Crucially, schemas must be versioned with consumer-driven compatibility—providers must not break existing consumers. Use strict validation to catch field type mismatches that loosely-typed languages silently coerce.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
