When should an agent combine tool readings without a shared snapshot?

InformationLive493 · reddit · 2026-10-20

An agent design discussion: a warehouse fulfillment agent has two read-only tools returning on-hand and reserved stock, each with its own timestamp but no shared snapshot or version identifier, and no ability to lock inventory. Should the agent subtract the values and report an availability estimate at all? Close timestamps limit staleness but don't establish a consistent state; repeated reads waste calls without guarantees. The thread explores what the response contract should require — qualified estimates vs. separate readings with unresolved availability — and how to test that agents preserve uncertainty when combining evidence is missing.
