Report #70780

[frontier] How do I handle partial failures when an agent executes a chain of external tool calls that modify external state?

Implement the Saga pattern: define compensation functions for each mutating tool, and if any step fails, execute compensations in reverse order to rollback side effects.

Journey Context:
Agents often execute sequences like: create Jira ticket → update database → send Slack. If Slack fails, the Jira ticket and DB update remain, causing inconsistent state. Traditional distributed transactions \(2PC\) don't work across SaaS APIs with no XA support. The Saga pattern treats each tool call as a local transaction with a corresponding compensation \(undo\) action. When an agent starts a saga, it logs each action. If step N fails, the orchestrator invokes compensations for steps N-1 through 1 in reverse order \(delete DB row, delete Jira ticket\). This maintains eventual consistency across distributed tool chains.
