Every time an agent modifies a file, stagewise records the change. You stay in full control — see exactly what changed, keep what you like, and undo what you don’t. Every edit is a discrete unit tracked at the tool-call level. You can accept, reject, or undo any edit independently.

​

How diff tracking works

When the agent edits a file:

1. The change is written to disk immediately
2. A diff is recorded — exactly what was added, removed, or modified
3. You review the change in the chat sidebar or the dedicated Diff Review page

​

Reviewing changes

​

In the chat sidebar

After the agent modifies files, a compact diff summary appears inline. Click it to expand the full diff with:

• Which files were changed
• Lines added and removed
• A preview of the actual changes

​

Diff Review page

For changes across multiple files, open the dedicated Diff Review page. It provides:

• A scrollable list of every modified file
• Side-by-side diff view
• Per-hunk and per-file controls

​

Accepting and rejecting changes

• Accept — Keep the change. Accepted hunks disappear from pending review.
• Reject — Undo the change. The file reverts to its previous state.
• Accept/Reject all — Apply your choice to every hunk in a file at once.

​

Undo and redo

Changed your mind? stagewise tracks the full edit history at the tool-call level:

• Undo — Roll back all changes from a specific agent action
• Redo — Reapply changes you previously undid

Step backward and forward through the agent’s entire edit history.

​

Design previews

Before the agent writes real code, use design previews to iterate on visual changes. The agent generates a preview of the result, letting you approve the direction before touching your actual files. This is especially useful for UI work — explore options quickly without committing to code.
