Sequential Pattern: Agents in a Pipeline

~10 min read

Each agent adds value step by step — one generates, the next reviews, a third deploys — the straightforward pipeline pattern used in workflow automation, ETL chains, and multi-step reasoning.

Key points

  • Each agent adds value step by step, in fixed order — one agent's output feeds directly into the next
  • The book's example: generate code -> review it -> deploy it, each stage building on the previous one
  • Used in workflow automation, ETL chains, and multi-step reasoning pipelines with genuine stage dependencies
  • Easy to reason about and debug, since there's a single linear path from input to output
  • Main limitation: total latency is the SUM of every stage's latency — no parallelism, even where some stages could theoretically run independently
