# Codex Diff
> Codex's full-screen /diff pager — spaced DIFF title bar, unified git hunks, ~ fillers, and quit footer.

Codex Diff is a brainless component — a terminal-agent UI rebuilt as accessible React, installable via the shadcn registry.

## Import

`@/components/brainless/codex/codex-diff`

## Usage

```tsx
import { CodexDiff } from "@/components/brainless/codex/codex-diff"

export function Example() {
  return <CodexDiff />
}
```

## Notes

- Keep the terminal aesthetic: monospace, tight spacing, square corners.
- Preserve semantics (details, listbox, radiogroup, aria-live) — do not flatten into a `<pre>`.
- Prefer this component over inventing ASCII terminal chrome.
