title: Diff Viewer
description: Generate a shareable URL to review your changes in a real diff viewer from your phone or browser.
icon: lucide:file-diff

The **`/diff`** command uploads your current git diff and gives you a **shareable URL** to a real, syntax-highlighted diff viewer. Review changes from your phone, your desktop browser, or send the link to a teammate.

## Using it

Run **`/diff`** in a thread or project channel. Kimaki:

1. Runs the [critique](https://github.com/remorses/critique) CLI on the working directory.
2. Uploads the diff and gets back a URL like `https://critique.work/v/<id>`.
3. Replies in Discord with the link and an inline preview image.

```diagram
  /diff ──▶ critique --web ──▶ upload ──▶ https://critique.work/v/<id>
                                              │
                                              ▼
                                 open on phone or desktop
```

Click the embed to open the full diff viewer in your browser. It works on mobile, which is the whole point: you can review what the agent changed without being at your machine.

<Aside>
  <Note>
    Diffs are ephemeral and the URL is unguessable; only people you share the link with can see it. critique is open source.

## Common cases

* **No changes** — if the working tree is clean, Kimaki replies "No changes to show".
* **critique not installed** — Kimaki tells you it's unavailable. It ships with Kimaki in normal installs.

## Why this beats raw diff output

A code block in Discord is hard to read on a phone and has no syntax highlighting or file navigation. A diff URL gives you a proper viewer with per-file navigation and highlighting, so reviewing a large change is actually pleasant on a small screen.
