The class: Runs a job on a queue or a clock, is safe to retry, and alerts when the job or its traces go dark.
- Idempotency key on every retry
- An alert when trace ingestion drops
Depot Pick: Upstash QStash
When not to use it: Need durable multi-step state/retries as code — Inngest/Temporal; need NATS subjects/leaf nodes — Synadia; need Kafka protocol/replay — WarpStream (or Confluent if that's already standard).
Runner-up: Inngest.

Failure modes this class and job share (5)
- Partial tool success: Require a per-item status and a failure count. Success for the task requires the failed count to be zero or explicitly handed to a retry queue.
- Non-determinism: Run the task more than once and compare the end state, not a single transcript. Record the trial count next to any success rate you cite.
- Observability gap: Alert on a drop in trace ingestion and on certificate expiry for the trace host. Do not treat a missing trace as a successful quiet run.
- Runaway spend: Set a budget and a tool-call cap per task. Alert when spend jumps. Stop the run at the cap instead of summarizing a partial trace as success.
- Tool loop: Hash the last several tool names and arguments. Stop when the same call repeats and the observation did not change. Cap tool calls per task.
