The hard prerequisite for prompt caching to take effect is prefix determinism: any dynamic content located in the prefix (timestamps, user IDs, randomly ordered tool lists) causes the cache key to change, driving the hit rate to zero.

UnverifiedThe idempotency key must come from stable input features (such as meeting ID or item content hash) and must not depend on the order or random IDs of this run, otherwise the key will change on rerun and deduplication will fail.70% similarUnverifiedCommon means of achieving idempotency include: assigning a unique request ID to each operation and deduplicating on the storage side; using optimistic locking or version numbers so that duplicate writes are rejected; and designing operations to set a final state rather than make incremental modifications.68% similarUnverifiedEvery external change needs an idempotency strategy: when the downstream API supports idempotency keys, derive them from the stable intent and effect identity; when it does not, create an application-side uniqueness record and look it up before retrying; after an ambiguous response, reconcile before repeating the action.66% similarUnverifiedVector stores recall memory entries by semantic similarity, and malicious instructions are automatically brought into context as long as they are semantically close to the current task.65% similarUnverifiedInfinite scrolling, randomly popping like notifications, and intermittent message alerts exploit the principle of 'variable ratio reinforcement,' operating on exactly the same logic as slot machines.64% similar
