Architectural Patterns

Patterns are reusable architectural designs and structural solutions to common problems. They describe the topology and relationships between agents and systems. Think of this as the “Engineering” of the domain.

What belongs here:

  • Architectural topologies (e.g., “Supervisor Agent”, “Context Gates”).
  • Common interaction models between components.
  • Solutions to recurring design challenges.
  • Structural diagrams and flow descriptions.
