SACP: Symposium Agent Client Protocol SDK

This repository houses the Symposium ACP SDK, which aims to:

1. Provide a nicer SDK for working with ACP in general - Type-safe, async-first, and easy to use for building agents and editors
2. Support proxy components for composable extensions - Build modular components that extend agent behavior without modifying the agent itself

Instead of building monolithic AI tools, SACP enables composable agent architectures through proxy chains where functionality can be added, removed, or reconfigured dynamically.
