# Screenshot Capture

Follow these save-location rules every time:

1) If the user specifies a path, save there.
2) If the user asks for a screenshot without a path, save to the OS default screenshot location.
3) If Codex needs a screenshot for its own inspection, save to the temp directory.

## Tool priority

- Prefer tool-specific screenshot capabilities when available (for example: a Figma MCP/skill for Figma files, or Playwright/agent-browser tools for browsers and Electron apps).
- Use this skill when explicitly asked, for whole-system desktop captures, or when a tool-specific capture cannot get what you need.
- Otherwise, treat this skill as the default for desktop apps without a better-integrated capture tool.

## macOS permission preflight (reduce repeated prompts)

On macOS, run the preflight helper once before window/app capture. It checks
Screen Recording permission, explains why it is needed, and requests it in one
place.

The helpers route Swift's module cache to `$TMPDIR/codex-swift-module-cache`
to avoid extra sandbox module-cache prompts.

```bash
bash <path-to-skill>/scripts/ensure_macos_permissions.sh
```

To avoid multiple sandbox approval prompts, combine preflight + capture in one
command when possible:

```bash
bash <path-to-skill>/scripts/ensure_macos_permissions.sh && \
python3 <path-to-skill>/scripts/take_screenshot.py --app "Codex"
```

For Codex inspection runs, keep the output in temp:

```bash
bash <path-to-skill>/scripts/ensure_macos_permissions.sh && \
python3 <path-to-skill>/scripts/take_screenshot.py --app "<App>" --mode temp
```

Use the bundled scripts to avoid re-deriving OS-specific commands.

## macOS and Linux (Python helper)

Run the helper from the repo root:

```bash
python3 <path-to-skill>/scripts/take_screenshot.py
```

Common patterns:

- Default location (user asked for "a screenshot"):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py
```

- Temp location (Codex visual check):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --mode temp
```

- Explicit location (user provided a path or filename):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --path output/screen.png
```

- App/window capture by app name (macOS only; substring match is OK; captures all matching windows):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --app "Codex"
```

- Specific window title within an app (macOS only):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --app "Codex" --window-name "Settings"
```

- List matching window ids before capturing (macOS only):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --list-windows --app "Codex"
```

- Pixel region (x,y,w,h):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --mode temp --region 100,200,800,600
```

- Focused/active window (captures only the frontmost window; use `--app` to capture all windows):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --mode temp --active-window
```

- Specific window id (use --list-windows on macOS to discover ids):

```bash
python3 <path-to-skill>/scripts/take_screenshot.py --window-id 12345
```

The script prints one path per capture. When multiple windows or displays match, it prints multiple paths (one per line) and adds suffixes like `-w<windowId>` or `-d<display>`. View each path sequentially with the image viewer tool, and only manipulate images if needed or requested.

### Workflow examples

- "Take a look at <App> and tell me what you see": capture to temp, then view each printed path in order.

```bash
bash <path-to-skill>/scripts/ensure_macos_permissions.sh && \
python3 <path-to-skill>/scripts/take_screenshot.py --app "<App>" --mode temp
```
