Review changes
After an agent plans and implements a change, you review the results before integrating it. In JetBrains Air, review is interactive. You can inspect diffs and also review changes in the context of the whole project by navigating to the modified files. You can revert parts you do not want and turn feedback into the next iteration.
Review can be done by a human or by an agent. This topic describes human review. For agent-based review, see Agentic review.
Review, revert, and iterate
Open the unified diff.
After a task is finished, the Chat tool shows the Changes button. Click it to open the merged diff in a single editor tab named Task Changes.
Navigate the diff and switch diff presentation.
Use the diff header to switch between diff views: Unified and Side-by-side. Use the navigation controls to jump to the next or previous hunk.
Revert or exclude changes you do not want.
There are two different ways to handle changes you do not want:
Revert removes changes from the working copy. To revert all changes in a file, use the revert action in the file header. To discard the entire result of the task, use Revert All in the diff header.
Exclude from commit keeps the change in the working copy but does not include it in the commit. Clear/select the hunk checkbox to stage only the parts you want to commit. This works like Git staging and takes effect when you commit (or when you apply changes locally and commit there).
Add review feedback and iterate.
If the result is not ready, add feedback and run a follow-up. Select code in the diff and choose Add to Task to request a specific change. This becomes input for the next iteration.
You can also add more context using the same tools as when defining a task: attach files and folders, mention symbols, add terminal output, or upload a file. Learn more in Task context.
Verify the result.
You can verify changes by running the project yourself or by asking the agent to run commands or tests. For example, ask the agent to run newly added tests, or run the app if it is a console project.
After the agent completes the follow-up, JetBrains Air shows the Changes button again. Each iteration returns you to the updated Task Changes tab.
