What you saw

[🦚 Manifest M201] Too many requests — wait a few seconds and retry.
See https://manifest.build/docs/errors/M201
The HTTP status is 429, so SDKs that respect retry-after will back off on their own.

Why it happened

Manifest caps each user at 200 requests per minute by default. The cap is there mostly to keep runaway loops from melting the proxy. Your agent crossed it inside a 60-second window.

How to fix it

  1. Add a small delay or exponential backoff on retry. Most SDKs handle this automatically when they see a 429.
  2. If parallel workers are hitting Manifest, throttle them so they share the budget.
  3. On a self-hosted install where you need more headroom, raise RATE_MAX_REQUESTS in proxy-rate-limiter.ts.
