GitHub Copilot CLI makes planning mandatory

The video’s core point lands: planning is what keeps an agent from turning autonomy into chaos. GitHub is betting that a little friction up front will buy a lot more trust on the back end.

• –Plan mode asks clarifying questions before execution, which should cut down on brittle, assumption-driven edits.
• –The surrounding feature set, including review, diff, undo, background delegation, and autopilot, suggests GitHub wants an end-to-end agent loop, not just a chat shell.
• –MCP, plugins, skills, and custom agents make the CLI a platform, so the planning step doubles as a control point before the toolchain fans out.
• –For developers, the tradeoff is clear: slower first steps, fewer cleanup passes later, especially on refactors and test-heavy tasks.
