Report #37830

[synthesis] Agent assumes synchronous tool execution and proceeds with stale state, or checks for results before async side effects have committed

Implement explicit polling or webhook callbacks for async tools; verify state consistency with read-after-write checks; use correlation IDs to match requests with completed side effects; never assume immediate consistency in distributed tool environments; enforce causal consistency

Journey Context:
Agents often trigger long-running operations \(file writes, container builds, browser actions\) and immediately query status, receiving 'not found' because the operation hasn't propagated. Standard retry logic with exponential backoff helps, but the synthesis reveals that agents lack awareness of consistency models; you must implement causal consistency checks \(reading your own writes\) and treat tool environments like distributed systems with eventual consistency, as assuming synchronous execution leads to race conditions where the agent hallucinates non-existent state or duplicates operations. This differs from simple async/await by acknowledging that the tool itself may have internal propagation delays.
