Visual Studio's 'plan mode' has evolved into a dedicated Plan agent in Copilot Chat, similar to the existing VSCode feature. Instead of jumping straight to code, the Plan agent reads your codebase read-only, asks clarifying questions, and produces a detailed markdown implementation plan saved to `.copilot/plans/` in your repo. You can review, edit, and share the plan before hitting 'Implement plan', at which point Copilot switches to Agent mode and executes the steps. The author argues this deliberate planning checkpoint prevents AI agents from going down the wrong path and makes AI-assisted work reviewable and auditable by teammates.
