Report #48608
[frontier] Agent workflows failing when tool schemas evolve but handoff payloads contain old field names
Implement schema drift resolution via intent matching, using embedding similarity to map legacy tool call structures to updated schemas during agent handoffs, allowing zero-downtime schema evolution
Journey Context:
Hard-coded schema validation breaks when tools update. Simple versioning requires maintaining multiple tool versions. Using vector similarity between old and new field descriptions allows automatic mapping of legacy payloads to new schemas, reducing breaking changes in production agent graphs.
