quietshrink — Agent Skill
You have access to cli-anything-quietshrink, a CLI for compressing video files on macOS Apple Silicon. It uses the Media Engine (hardware HEVC encoder), not the CPU, so encoding is fast and silent.
When to use it
- User wants to compress a screen recording, screencast, or any .mov/.mp4 file
- File is too large to share (chat, email, GitHub)
- Need smaller files but cannot tolerate visible quality loss
- Apple Silicon Mac (M1/M2/M3/M4) — best results
Don't use this on non-screen content (camera footage, vlogs) — savings will be much smaller because there are no duplicate frames to drop.
