Read what is on the user's Mac screen - the accessibility tree, window contents, UI elements, or a screenshot. Use when the user asks what is on their screen, what an app is showing, to find a button or field, or to check the state of something before acting on it.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Reading the screen

Two ways. Pick the cheap one.

## Default: the accessibility tree

```bash
chewie see --app Safari
chewie see --app Mail --json
chewie see                      # frontmost app
```

You get structured JSON: every button, field, menu item and row, with a role, a name,
a value, and a stable ref like `@s8f3k2p9:e12`. About 50ms. A fraction of the tokens a
screenshot costs.

Search instead of dumping everything when you know what you want:

```bash
agent-desktop find --role AXButton --name "Save"
agent-desktop get @s8f3k2p9:e4 value
```

This works on **background windows**. No focus stealing, no cursor hijack, and the user
can keep working while you read another app.

## Empty or unnamed? It is Electron.

Chrome, Edge, VS Code, Slack, Discord, Notion, Figma, Spotify. Chromium builds its
accessibility tree lazily and hands you nothing until a client asks.

```bash
chewie see --app Slack --force-ax
```

Sets `AXManualAccessibility` on the app element, waits ~400ms for the tree to
populate, re-reads. The wait is not optional; an immediate re-read still looks empty
and people conclude the fix does not work.

## Screenshot: only when the tree genuinely cannot see it
…

How to install

The exact contents, by fingerprint
mdr add calebnewtonusc/chewbacca/mac-see@sha256:e82ee81704c1b9f2

The line at the top of this page pins the label git:20260904.ee0eb1b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
