# Change Sets

Change sets are snapshots of file changes captured during task execution. Each sync produces a new change set so you can review progress over time.

## What a change set includes

* File change list
* Unified and split diffs
* Line additions and deletions
* Optional pull request metadata

## Diff views

You can review changes with:

* Split diff: side-by-side view
* Unified diff: single stream view

Use the view toggle on the task page to switch formats.

## Copy helpers

From the task header menu you can:

* Copy patch
* Copy git apply

These are useful for applying changes locally or sharing them with teammates.

## Tips for reviews

* Focus on the latest change set first.
* Validate high-impact files before opening a PR.
* Use additions/deletions to understand scope quickly.
