Build an interview coach app with the GitHub Copilot SDK
Summary
The GitHub Copilot SDK enables developers to embed Copilot's agent runtime into custom applications, demonstrated by an interview coach app. This allows applications to define agents with specific instructions and custom tools, leveraging Copilot for model interaction and tool execution.
- The GitHub Copilot SDK allows embedding Copilot's agent runtime into custom applications, extending its use beyond code editing.
- Applications define agents with specific instructions and custom tools, while Copilot handles model interaction and tool calls.
- The sample uses Microsoft Agent Framework to orchestrate multiple Copilot-backed "specialist" agents for different interview stages.
- Custom tools are exposed to Copilot via SessionConfig using a "custom:" prefix to distinguish them from built-in tools.
This article is relevant for developers looking to build agent-based applications or internal workflows by reusing an existing LLM agent runtime like GitHub Copilot.
