What it does

CLI Anything Quietshrink is an agent skill from HKUDS/CLI-Anything. Compress macOS screen recordings with zero CPU stress using Apple Silicon's hardware HEVC encoder. Typically reduces file size 70-90% while staying visually lossless. Computer stays silent during encoding.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative. It works with macOS and FFmpeg. The repository describes itself as: "CLI-Anything: Making ALL Software Agent-Native" -- CLI-Hub: https://clianything.cc/. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 34f5195. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- brew
- ffmpeg
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

CLI Anything Quietshrink loads about 865 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 216 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~58
When it runs · the whole SKILL.md, loaded when a task matches: ~865

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

Commands

bash

# Compress with default transparent quality
cli-anything-quietshrink compress <input> [output]

# Compress with specific preset
cli-anything-quietshrink compress -q tiny <input>     # smallest
cli-anything-quietshrink compress -q transparent <input>  # default, visually lossless
cli-anything-quietshrink compress -q pristine <input>     # near-source quality

# Inspect a file before compressing
cli-anything-quietshrink probe <input>

# List quality presets
cli-anything-quietshrink presets

# Verify environment
cli-anything-quietshrink doctor

All commands accept --json for machine-readable output.

Quality presets

Preset	q	Typical reduction	SSIM	Use case
`tiny`	50	~90%	~0.95	Chat/email — small artifacts OK
`balanced`	55	~88%	~0.99	Docs/sharing — high quality
`transparent` (default)	60	~87%	~0.99+	Anything important — visually lossless
`pristine`	70	~84%	~0.997	Archival — near-source

JSON output schema

compress returns:

json

{
  "input": "/path/to/input.mov",
  "output": "/path/to/output.mov",
  "input_size": 105952129,
  "output_size": 12345678,
  "saved_bytes": 93606451,
  "saved_percent": 88.3,
  "duration_seconds": 193.3,
  "elapsed_seconds": 87,
  "encoding_speed": "2.2x",
  "quality_preset": "transparent",
  "q_value": 60,
  "gop": 600
}

probe returns:

json

{
  "path": "...",
  "size_bytes": 105952129,
  "size_mb": 101.04,
  "codec": "h264",
  "width": 3024,
  "height": 1964,
  "framerate": "120/1",
  "duration_seconds": 193.31
}

Decision flow for agents

User wants to share a recording
  ├─ Is it on Apple Silicon Mac? → use quietshrink
  │  ├─ For chat/email/quick share → -q tiny
  │  ├─ For docs/important sharing → -q transparent (default)
  │  └─ For archival/editing → -q pristine
  └─ Not on Mac? → falls back to software, less efficient

Before processing, run doctor to verify environment. For unfamiliar files, run probe to understand resolution/codec/duration.

Errors and recovery

ffmpeg not found → brew install ffmpeg
hevc_videotoolbox not available → brew reinstall ffmpeg
compression_failed → check input file isn't corrupted; try --verbose mode to see ffmpeg errors
