Compose Multi-Gene Agent Pipelines

Rotifer genes are powerful on their own, but the real magic happens when you compose them. The gene algebra — Seq , Par , Cond , Try , and Transform — lets you wire simple genes into complex agent pipelines that are type-safe, verifiable, and automatically optimizable. In this tutorial, you'll build a real-world pipeline: search the web → summarize results → format output — then extend it with parallel execution, conditional branching, and error recovery. Prerequisites Rotifer CLI installed ( npm i -g @rotifer/playground ) A project initialized ( rotifer init my-pipeline && cd my-pipeline ) Familiarity with basic gene concepts (see Your First Gene in 5 Minutes ) Step 1: Understand the Building Blocks Your project already includes genesis genes. Let's check what we have: rotifer arena list ┌──────┬─────────────────────┬────────────┬────────┬──────────┐ │ # │ Name │ Domain │ F(g) │ Fidelity │ ├──────┼─────────────────────┼────────────┼────────┼──────────┤ │ 1 │ genesis-web-search │ searc
