Debugging UI with AI: GitHub Copilot agent mode meets MCP servers

During a recent Rubber Duck Thursdays stream, Chris Reddington revisited his OctoArcade Next.js app and tackled various UI issues using GitHub Copilot's agent mode and Playwright MCP server. This approach allowed Copilot to autonomously identify and address bugs, such as overlapping navigation headers and unintended gaps in the UI. Reddington emphasized the importance of clear, detailed requirements to maximize the effectiveness of AI tools like Copilot, which can simulate user actions and propose solutions through iterative debugging. While the process involved several iterations to refine the requirements and achieve the desired outcomes, it highlighted the potential of agentic tools to streamline debugging and improve development workflows. Reddington also underscored the significance of keeping Copilot's custom instructions updated and iterating in small steps to manage changes effectively.
