Report #86960
[architecture] Silent schema drift between agent outputs and downstream expectations
Enforce JSON Schema validation with additionalProperties: false and strict type checking at every handoff; version schemas explicitly and reject unknown fields
Journey Context:
Without strict schemas, agents subtly break contracts by adding fields or changing types. The temptation is to use 'flexible' schemas for 'future-proofing' but this masks breaking changes. Strict validation with additionalProperties: false catches drift immediately, forcing explicit versioning when contracts change rather than allowing silent failures that cascade downstream.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
