When a large Workflow/Agent fan-out (dozens of parallel subagents on Opus) mass-fails with "Server is temporarily limiting requests (not your usage limit)" / HTTP 429 — most agents dying, a few that finished before the burst surviving — recover by re-running the SAME fan-out on Sonnet and throttled into sequential waves (not one wide burst). Use when: (1) a Workflow returns far fewer results than dispatched and the failures all read "Rate limited" / 429 with "not your usage limit"; (2) you…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Opus rate-limit on a fan-out → retry on Sonnet, throttled into waves ## Problem A wide parallel fan-out (Workflow `parallel()`/`pipeline()` or many concurrent `Agent` calls) launched on **Opus** mass-fails with a server-side capacity throttle, not your account quota. The whole fan-out collapses to a handful of results — only the agents that happened to finish *before* the burst survive. ## Context / Trigger Conditions - Failure string (one per dead agent): **`API Error: Server is temporarily limiting requests (not your usage limit) · Rate limited`** → HTTP **429**. - The "(not your usage limit)" clause is the tell: this is **Anthropic-side Opus capacity throttling**, NOT your per-account rate limit. Waiting and retrying on Opus alone often re-hits it. - You launched many subagents at once (one `parallel()` over 20–50 items, or a single message with dozens of `Agent` calls). The wider the simultaneous burst, the worse. - Distinct from the empty-`StructuredOutput` loop (that's a *schema*-payload failure under the same storm — see the companion skill `workflow-schema-agents-empty-loop-under-ratelimit`). …

How to install
mdr add wan-huiyan/agent-traffic-control/opus-ratelimit-fanout-retry-on-sonnet-throttled-waves@sha256:ddcd0910ac530965The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
