Details
The VS Code team has detailed the rationale and architecture for introducing Agent Host, a dedicated process that separates agent sessions from the Extension Host.
By applying the GitHub Copilot SDK to the Copilot harness, they ensured consistent behavior across VS Code, Copilot CLI, and Copilot apps. Additionally, they support the synchronization of a single live session across various environments, such as the editor, agent pane, and browser.
Key technical features include:
- Remote Machine Hosting: Supports running Agent Host on remote machines
- Multi-Harness Support: Simultaneously supports multiple harnesses while maintaining their unique characteristics
- AHP Protocol: An open protocol named Agent Host Protocol that allows anyone to build their own clients
