The Swarm Pattern
5.1Concept: Decentralized Test GenerationUnlike the Orchestrator, the Swarm pattern has no single coordinator. Multiple independent agents work on the same codebase simultaneously…5.2ArchitectureEach agent: 1. Receives its assigned module or code area 2. Independently analyzes the code and generates tests 3. Submits its test suite…5.3ImplementationEach agent in the swarm is focused on its module:5.4The Reconciler: The Critical ComponentThe Reconciler is what makes the swarm work. Without it, you get duplicate tests, naming conflicts, and inconsistent patterns.5.5Partitioning StrategiesHow you divide work across swarm agents affects coverage and duplication:5.6When to Use the Swarm PatternBest for: - Maximum coverage breadth (each agent explores independently) - Large codebases that can be cleanly partitioned by module…5.7Swarm vs Orchestrator Comparison5.8Key TakeawayThe Swarm pattern trades coordination overhead for maximum parallelism and coverage breadth. Its success depends entirely on the quality of…
