## What it does

The skill uses `peekaboo` to capture a full screen, a named app window, or a selected region, and to extract visible text with OCR. It uses `camsnap` for webcam images, but only when the user explicitly asks for one. After capture, the agent reads the image file to inspect its contents.

\`peekaboo` needs macOS screen recording permission; `camsnap` needs camera permission. OCR results depend on font size and screen resolution, so small text can be harder to extract. To install for Claude Code, run `npx skills add daxaur/openpaw --skill c-screen -a claude-code`; the skill file is placed at `~/.claude/skills/c-screen/SKILL.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-screen -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/c-screen/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/c-screen/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-screen -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/c-screen/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add daxaur/openpaw --skill c-screen -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/c-screen/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**

```bash
npx skills add daxaur/openpaw --skill c-screen -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/daxaur/openpaw --path skills/c-screen
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/c-screen/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**

## When to use it
- capture the full screen for visual inspection
- extract visible text from a screen with OCR
- save an image of a specific app window
- capture a frame from a selected webcam

## What This Skill Does

Enables Claude to take screenshots, extract text from the screen via OCR, and capture webcam images for visual analysis using `peekaboo` and `camsnap`.

## Available CLI Tools

### `peekaboo` — Screenshots & OCR

```bash
# Take a full screenshot and save to file
peekaboo screenshot --output ~/Desktop/screen.png

# Take screenshot and extract all text via OCR
peekaboo ocr

# OCR a specific region (x, y, width, height)
peekaboo ocr --region 0,0,1280,720

# Screenshot a specific window by app name
peekaboo screenshot --app "Safari" --output window.png

# Screenshot and pipe to stdout for immediate analysis
peekaboo screenshot --stdout
```

### `camsnap` — Webcam Capture

```bash
# Capture a single webcam frame
camsnap --output ~/Desktop/photo.jpg

# Capture with a specific camera device
camsnap --device 0 --output shot.jpg

# Capture and print file path
camsnap --output /tmp/cam.jpg && echo "Saved"
```

## Usage Guidelines

- Use `peekaboo ocr` when the user wants text extracted from the screen
- Use `camsnap` only when the user explicitly wants a webcam image
- After capturing, read the image file to analyze its contents visually

## Notes

- macOS screen recording permission required for `peekaboo`
- Camera permission required for `camsnap`
- OCR accuracy depends on font size and screen resolution
