Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

c-screen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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

# 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

# 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
