GitHub Copilot 计划模式与自定义 AI 代理：一个意外发现

While attempting to write an article about recent VS Code updates using a custom article-writing agent, an unexpected outcome occurred. The custom agent was designed to ask clarifying questions before writing, with specific instructions to gather context, understand the audience, and clarify the angle. However, it only asked one or two questions before starting to write. In contrast, GitHub Copilot's out-of-the-box plan mode was probing deeper, asking more thoughtful questions, and generally performing better than the specialized tool I had built. This moment crystallized the realization that sometimes building custom AI solutions is not the best approach, and it is better to let existing tools take the lead.
