[synthesis] Agent chains tool calls assuming synchronous state propagation when underlying systems use eventual consistency

Always insert a verification/polling step between dependent tool calls when interacting with distributed systems; do not assume immediate consistency after a 'success' response

Journey Context:
When Tool A \(create resource\) returns success, agents assume the resource exists for immediate use by Tool B \(configure resource\). However, in cloud APIs \(AWS, GCP\), distributed databases \(Cassandra, DynamoDB\), and CI/CD pipelines, success means 'request accepted' not 'state propagated'. Tool B fails with 'not found', leading the agent to debug Tool B's syntax \(wrong path\) rather than recognizing temporal decoupling. The synthesis combines distributed systems theory \(eventual consistency\) with agent orchestration patterns. The fix requires treating inter-tool dependencies in distributed systems as requiring polling or verification loops, not direct chaining.
