Report #87277

[frontier] Agent workflows failing mid-trajectory and losing hours of progress on expensive reasoning chains

Adopt durable execution patterns \(Temporal.io or Cadence\) to persist agent state after every tool call, enabling automatic replay from last known good state on crashes, and implement 'compensating transactions' for undoing partial side-effects across distributed tools

Journey Context:
Agent workflows are long-running and inherently flaky due to API timeouts, rate limits, or infrastructure crashes. A crash after 20 minutes of reasoning wastes tokens and time. 'Durable execution' treats the workflow as event-sourced: every step \(LLM call, tool result\) is logged to a durable store \(Temporal, Cadence\). On failure, the system replays the log to reconstruct state without re-executing side effects \(using idempotency keys\). On success, the saga pattern handles distributed transactions across multiple tools with rollback logic \(e.g., if payment succeeds but inventory fails, trigger compensation\). This brings mainframe-grade reliability to agentic processes, allowing agents to run for hours or days without losing progress.
