It addresses the challenge of building flexible and extensible AI agent systems by making every part a plugin, allowing developers to swap or compose components without tight coupling. This contrasts with monolithic agent frameworks, enabling easier customization and community-driven plugin sharing.

Developers can build custom AI agent workflows with a modular plugin system, integrating various tools, models, and UI components. Real-world use cases include creating specialized assistants, automating complex tasks with custom tool integrations, and building multi-agent systems. The ceiling is high due to the plugin ecosystem and Cordis's composability paradigm, allowing for sophisticated spatiotemporal compositions.
