機能

Rider

• Agent Client Protocol (ACP) agent registry support - You can now browse and install ACP-compatible AI agents directly from a curated registry in the AI Chat tool window. ACP defines a standard protocol for AI coding agents, letting Rider connect to any compatible agent without custom integrations. Users can add agents from the registry and use them immediately in AI Chat.
