Action Steps
  1. Implement retry mechanisms with exponential backoff to handle transient errors
  2. Use circuit breakers to detect and prevent cascading failures
  3. Configure fallback behaviors for critical components like API calls
  4. Monitor and log errors to facilitate quick debugging and resolution
  5. Apply idempotence principles to ensure safe retries and prevent data corruption

You have a document processing pipeline. It ingests contracts, extracts key clauses, validates them against policy, and generates a summary. Monday morning it processes 200 documents without a hiccup. Tuesday at 2 AM, Anthropic’s API returns a 429, the extraction node throws, and the entire pipeline stops. Not just the one document — the whole batch. Your on-call engineer spends 45 minutes figuring out it was a transient rate limit that would have resolved itself with a 2-sec
