plugin-based architecture
An architectural model where functionalities are added as interchangeable modules or plugins, allowing flexibility and extensibility in software systems.

When to use it
Use a plugin-based architecture when a monolithic system becomes too rigid for evolving requirements. Plugin-based architectures allow developers to add, remove, or update functionalities without altering the core system, enabling modular updates like integrating new AI models or third-party tools.
Quick example
In DeepSeek Harness, developers can extend the AI agent's capabilities by adding plugins for local data processing and tool integration. The Harness framework itself is a plugin-based architecture, allowing developers to customize the agent's functionality while keeping the core system stable. This modularity enables developers to swap out components like NLP models or data connectors without rewriting the entire application.
Ecosystem
Plugin-based architectures interact with various components that can be added or removed as needed, enhancing system flexibility and maintainability.

Misconceptions
| Misconception | Rebuttal |
|---|---|
| Plugins are always third-party | Plugins can be developed in-house for custom needs |
| It's only for large systems | Small projects benefit from modularity too |
| Plugins slow down performance | Efficient design minimizes overhead |
Trade-offs
- Flexibility — requires careful version management
- Extensibility — potential for plugin conflicts
- Customization — increased complexity in plugin interfaces
