Selecting and Composing Agent Design Patterns: Industrial Case Evidence and Controlled Reference-System Experiments

Agent pattern catalogs describe architectural alternatives, but engineers also need evidence for selecting and composing them.

Key points

  • We extend a cognitive-function--execution-topology framework with an evidence-driven selection procedure and explicit composition contracts.
  • The study combines two industrial case accounts, a contributor's collaboration design, seven practitioner workshops, and executable fault-injection experiments.
  • A 2 x 2 ablation separates function-specific contracts from execution controls across 36 scenario families, with ten input variants per family.
  • Recovery without consumer-side verification increases false-success cases in the map surrogate.
