GitHub Copilot App Simplifies AI Code Verification with Integrated Diff, Terminal, and Browser

The GitHub Copilot app has improved the process of reviewing and executing code generated by AI agents by integrating diff, terminal, and browser panels into a single interface. Previously, frequent switching between the editor, terminal, and web browser was required, but now verification can be done without interrupting the workflow through built-in panels.

Reviewing and Executing Changes

The diff panel visually compares added (green) and deleted (red) code to clearly show changes. Users can accept changes, leave comments, or request additional modifications. In the terminal panel, users can directly run project-specific commands or configure scripts (Run button) to start servers, and open multiple terminal windows simultaneously to work in parallel.

UI Verification and Iteration

The browser panel handles the final verification of projects that include UI. After running the development server, functionality can be tested as if it were a live website, and the Pick & Polish tool allows users to select specific elements and refine details with the agent. After modifications, the development server can be run again to immediately check the changes.

Benefits of an Integrated Workflow

This integration simplifies the process of answering three key questions: "What changed?", "Does it run?", and "Does it actually work?" By completing review, execution, and preview in one place and accepting changes to create a Pull Request, the stability of AI-generated code can be ensured without switching tabs.
