[synthesis] Agent assumes a tool call changed the environment state, but the call was silently dropped or rate-limited

Implement idempotency keys and state-reconciliation checks. Never assume an action succeeded based on the agent's internal log; always query the environment state after a mutation to confirm the change took effect.

Journey Context:
Agents often assume their actions are atomic and successful if no error is returned. However, in distributed systems, tool calls can be silently dropped, rate-limited \(HTTP 429\), or fail asynchronously. The agent will then base its next steps on an imagined state that diverges from reality. This is a synthesis of LLM agent architecture and distributed systems failure modes: the agent's context is a cache of the world state, and like any cache, it can become stale if writes are not confirmed.
