Architecture SOLID Design

SOLID System Design

AgentMesh was architected from day one according to SOLID software engineering principles:

---

1. Single Responsibility Principle (SRP)

• WorkflowGraph: Only responsible for topological graph representation.
• Scheduler: Only responsible for dependency resolution and execution orchestration.
• PriorityReadyQueue: Only responsible for ordered task queuing.

2. Open/Closed Principle (OCP)

• Pluggable state backends (IStateRepository), dispatchers (ITaskDispatcher), and load balancers (ILoadBalancer).

3. Liskov Substitution Principle (LSP)

• Any implementation of IStateRepository (RAM, PostgreSQL) satisfies all persistence invariants without side effects.

4. Interface Segregation Principle (ISP)

• Interfaces are minimal, cohesive, and decoupled.

5. Dependency Inversion Principle (DIP)

• High-level orchestration depends exclusively on abstract interfaces. Concrete details (network, databases) are injected via constructor dependency injection.\n
