Screenshot CLI

One-command screen capture plus post-processing via screenshot.py in this directory (PEP 723 script, mss + Pillow; uv run handles dependencies, no setup). Prefer it over screencapture + sips: screencapture -R takes Retina points (2x pixel surprise) and sips --cropOffset silently center-crops. This CLI uses one consistent unit — whatever --list-monitors reports — verified: -r 100,100,800,600 yields an 800x600 image.

Quick start

screenshot.py ships alongside this SKILL.md — set S to its path inside this skill's directory (the base directory reported when the skill loads):
