Diff viewer

When an agent modifies a file, the diff viewer shows you exactly what changed. You can review line-by-line, accept or reject individual chunks, and navigate between changes.

How it works

When an agent writes to a file, the render pane automatically switches to diff mode. You see the current file with changes highlighted — added lines, removed lines, and modifications.

You can also open a diff manually: create a render pane, select a file, and switch the mode dropdown to Diff. This compares the working copy against the last git commit.

Reviewing changes

Each change is a chunk — a group of related additions or deletions. The status bar shows your progress: "3 of 5 chunks reviewed".

• Added lines appear highlighted in the file
• Deleted lines appear with a reveal control on hover
• Navigate between chunks with the arrow buttons in the toolbar

Accepting and rejecting

Each chunk has Accept and Reject controls:

• Accept — keep the change as-is
• Reject — revert to the original content

This lets you cherry-pick the good parts of an agent's output and discard the rest, without accepting or rejecting the entire file.

Supported file types

The render pane handles more than just code:
