ClawHub - YouTube Downloader & Clipper

Clip and download specific time ranges or full YouTube videos in various qualities, including audio-only MP3 extraction, using precise timestamps.

Security Scan

The skill's files and runtime instructions are consistent with a YouTube clipping/downloading tool — it auto-generates and runs Python yt-dlp-based code and installs yt-dlp if needed; nothing in the package attempts to access unrelated secrets or system areas.

Purpose & Capability

Name, README, SKILL.md, prompt.md and code all describe a YouTube clipping/downloading tool and request only the capabilities needed for that (downloading via yt-dlp, optional ffmpeg for audio). There are minor metadata mismatches (skill.json version 1.0.0 vs registry 1.1.1) and authoring references to 'Claude', but these are not security-critical.

Instruction Scope

The runtime instructions direct the agent to generate, write, execute, and then delete a temporary Python script and to auto-install the yt-dlp Python module via pip. That behavior is coherent for this purpose but means the skill will run code locally and modify the Python environment at runtime — sensible for a downloader but worth noting.

Install Mechanism

There is no remote download/install of arbitrary archives. An included install.sh only copies files into ~/.claude/skills and checks for yt-dlp/ffmpeg. The skill is instruction-only at runtime (creates temporary Python scripts) and does not pull code from untrusted URLs.

Credentials

The skill requests no environment variables, no credentials, and references only local tools (python, yt-dlp, ffmpeg). The requirement to pip-install yt-dlp is proportional to its function. No unrelated secrets or config paths are requested.

Persistence & Privilege

always is false and the skill does not request elevated or persistent platform privileges. install.sh installs files into the user's home skill directory only and does not modify other skills or system-wide settings.

Assessment

This skill appears to be what it claims: a yt-dlp-based YouTube clipper. Before installing/using it, be aware that (1) it will generate and execute temporary Python scripts on your machine, (2) it may run pip install to add the yt-dlp module to your Python environment (which can modify system/site packages depending on your Python setup), and (3) audio extraction may require ffmpeg (a separate binary). If you are comfortable allowing a skill to write and run short Python scripts and to install a Python package, this is proportional for the stated purpose. If you prefer to avoid modifying your environment, run it inside a virtualenv/container or inspect the generated script before execution. Also ensure you comply with copyright rules for downloaded content.

Extracts from 30 seconds to 2 minutes 15 seconds.

Clip with quality selection

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ --clip 01:00-03:30 --quality 1080p

Extracts a 1080p clip from 1 minute to 3 minutes 30 seconds.

Clip audio only

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ --clip 00:10-01:00 --audio-only

Extracts audio from 10 seconds to 1 minute as MP3.

Clip with custom filename

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ --clip 02:00-04:30 --output highlight.mp4

Clip tutorial section

/clawhub https://youtube.com/watch?v=tutorial123 --clip 05:20-12:45 --quality 720p

Perfect for extracting specific tutorial steps.

Clip music section

/clawhub https://youtube.com/watch?v=music456 --clip 01:15-02:30 --audio-only --output chorus.mp3

Download Examples (Secondary Use)

Download full video

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ

Download in specific quality

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ --quality 720p

Extract full audio

/clawhub https://youtube.com/watch?v=dQw4w9WgXcQ --audio-only

Available Options

Option	Description	Example
--clip <start>-<end>	PRIMARY FEATURE - Clip from start to end time	--clip 00:30-02:15
--quality <resolution>	Specify quality (720p, 1080p, best)	--quality 1080p
--audio-only	Extract audio as MP3	--audio-only
--output <filename>	Custom output filename	--output my_clip.mp4
--format <format>	Output format (mp4, mkv, webm, mp3)	--format mkv

Time Format for Clipping

The skill accepts flexible timestamp formats:

• MM:SS: 01:30 (1 minute 30 seconds)
• HH:MM:SS: 01:15:30 (1 hour 15 minutes 30 seconds)
• M:SS: 1:30 (same as 01:30)
• SS: 90 (converted to 01:30)

How Clipping Works

1. You provide a YouTube URL and time range
2. Claude parses your timestamps
3. The skill extracts just that section using optimized methods:
   • Method 1: yt-dlp's native clipping (fastest)
   • Method 2: ffmpeg precise cutting (fallback)
4. Your clip is saved to the current directory

Use Cases

Content Creators

• Extract highlights for shorts or reels
• Clip reaction sections
• Create compilation segments
• Extract B-roll footage

Educators

• Clip specific tutorial steps
• Extract lecture segments
• Create study materials
• Share specific explanations

Musicians

• Extract song sections
• Clip audio for remixes
• Get specific verses or choruses
• Create practice loops

Researchers

• Extract relevant video segments
• Create timestamped references
• Archive specific content
• Analyze particular sections

Output Location

All clips and downloads are saved to your current working directory. You can specify a custom path using the --output flag.

Important Notes

• Pure Python solution - no binary dependencies, just Python
• Auto-installs dependencies - yt-dlp Python module installed automatically if needed
• Clipping is optimized and fast - no need to download full videos first
• Quality is maintained - clips preserve the original video quality
• Copyright matters - only clip content you have rights to access
• Flexible timestamps - use whatever format is natural for you
• Minimal setup - Python is usually pre-installed, everything else is automatic

Technical Details

• Language: Pure Python implementation
• Primary Library: yt-dlp Python module (auto-installed via pip)
• Audio Processing: ffmpeg (required for audio extraction, usually pre-installed)
• Supported Formats: All standard video and audio formats
• URL Support: youtube.com, youtu.be, and all YouTube URL variants
• Installation: Fully automatic - checks and installs yt-dlp module as needed

Troubleshooting

Clip not extracting correctly

The skill will automatically try alternate methods if the first approach fails.

Invalid timestamps

Use format: MM:SS or HH:MM:SS (e.g., 01:30 or 01:15:30)

Video unavailable

Verify the YouTube URL is correct and the video is publicly accessible.
