Use Forge Plan mode for larger structural changes
Plan mode lets you review every change Forge intends to make before a single line of code is written — essential for confident, large-scale edits.
Switch to Plan mode
In the Forge chat toolbar, click the mode selector (defaults to Agent) and choose Plan. The input box label will change to reflect the active mode.
Describe the structural change
Explain what you want to refactor or add in plain language. For example: "Restructure the project to use a separate API layer, and move all database calls out of the UI components." Forge will analyse the current codebase before responding.
Review the proposed plan
Forge returns a step-by-step plan listing every file it intends to create, modify, or delete — along with the reasoning for each change. Read through it carefully before approving.
Approve or redirect
Click Approve Plan to execute all the changes at once, or respond in the chat to adjust the plan first. Once approved, Forge applies every change and creates a checkpoint so you can roll back if needed.
Verify in the preview
After execution, the live preview will reload. Click through the key flows you changed to confirm everything still works as expected. If something is off, describe the issue in the chat and Forge will fix it.
