  "name": "open-oncall-failover",
  "description": "Open Oncall provider failover block. Runs one agent-task prompt on a chain of up to three workers of different harnesses (default claude, then codex, then opencode). Each attempt that fails (provider down, rate limit, auth, crash, or a staged drill) re-runs the same prompt on the next harness. The pick node returns the first successful JSON output plus a per-attempt provider record (harness, agent, status, failure reason, providerError). Called as a sub-workflow by open-oncall for the investigate and fix steps.",
