New Repository Exploration Capabilities

GitHub has made it easier to explore and understand repository structures when working with Copilot on the web. Developers can now ask Copilot to display files and simultaneously browse the full file tree alongside the file contents, providing a more comprehensive view of how files relate to the broader codebase.

Automatic Reference Management

A key improvement is how files are integrated into conversations. As you navigate the file explorer:

• Automatic temporary references: Files you select get automatically added to your current chat as temporary references
• Persistent references: You can convert temporary references to permanent ones by clicking the reference token or double-clicking the file preview tab
• Contextual awareness: This deeper view of the codebase makes it easier to jump between files and ask Copilot relevant questions with proper context

Availability and Next Steps

This feature is now available in public preview on GitHub's web interface. Developers interested in discussing this feature or providing feedback can join the conversation in GitHub Community.

The update builds on GitHub's recent momentum in Copilot enhancements, including auto model selection in JetBrains IDEs and semantic code search improvements for faster coding agent performance.
