Using plan mode
In plan mode, Proto investigates first and presents a step-by-step plan. Nothing changes until you approve it.
Start plan mode
Ask for it in plain language, for example “Plan this first” or “Show me the plan before you build anything.” Proto may also switch to plan mode on its own before a larger implementation task.
Review the plan
When the plan is ready, a Review Plan card asks “Ready to implement?” and shows two buttons:
| Button | What happens |
|---|---|
| Implement plan | Proto starts carrying out the plan. |
| Request changes | A feedback box opens. Describe what to change and click Send revision, or click Cancel to go back. Proto revises the plan and asks again. |
If you don’t want to go ahead, don’t implement the plan. Tell Proto what you’d like instead.
