Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.05061 |
| Opus 5 | $0.00000 | $0.02531 |
| Sonnet 5 | $0.00000 | $0.01012 |
| Haiku 4.5 | $0.00000 | $0.00506 |
Grade B, and why
video-cleaning scanned grade B with 1 finding 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 12d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Video Cleaning Skill
Automated video transcription and editing workflow that removes pauses and filler words from Korean videos using OpenAI Whisper API and MoviePy for frame-accurate cuts.
When to Use This Skill
Use this skill when you need to:
- Clean up recorded presentations or talks
- Remove awkward pauses and "uh/um" sounds from videos
- Reduce video length by removing dead air
- Create polished videos from raw recordings
- Process Korean language videos with natural speech patterns
Perfect for: Presentation recordings, lecture videos, podcast recordings, interview footage, or any speaking video that needs cleaning.

Requirements
System Requirements
- FFmpeg: Video processing tool (must be installed)
- macOS:
brew install ffmpeg - Linux:
sudo apt install ffmpeg - Windows: Download from ffmpeg.org
- macOS:
Python Requirements
- OpenAI Python SDK:
pip install openai - MoviePy:
pip install moviepy(video editing with frame accuracy) - OpenAI API Key: Set environment variable
OPENAI_API_KEY- Get your API key from platform.openai.com
- Cost: ~$0.15 per 25-minute video (Whisper transcription)
Python Version
- Python 3.7 or higher
How It Works
This skill uses a two-step workflow:
Step 1: Transcription (transcribe_video.py)
- Extracts audio from video using FFmpeg
- Sends audio to OpenAI Whisper API for transcription
- Receives word-level timestamps (precise timing for each word)
- Generates three output files:
{video_name} - transcript.json(complete API response){video_name} - transcript.md(formatted markdown){video_name} - word_timings.txt(simple text reference)
Step 2: Video Editing (edit_video_remove_pauses.py)
- Loads word-level transcript from Step 1
- Identifies long pauses between words (> 1.0 seconds by default)
- Identifies Korean filler words (어, 음, 아, 이, 오, 저)
- Calculates which video segments to keep
- Uses MoviePy for frame-accurate cutting and reassembly
- Generates edited video and detailed report
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

video-cleaning is a skill published in the GitHub repository jykim/claude-obsidian-skills (50 stars, last pushed 20d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,061 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
