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.

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 | $0.00030 | $0.01501 |
| Opus 5.5 | $0.00012 | $0.00600 |
| Sonnet 5.5 | $0.00006 | $0.00300 |
| Haiku 4.5 | $0.00003 | $0.00150 |
Grade D, and why
youtube-transcript scanned grade D with 3 findings 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 1mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

YouTube Transcript Skill
Download and analyze YouTube video transcripts with automatic frame extraction at visual reference points.
Usage
/youtube-transcript <youtube-url>
What This Skill Does
- Downloads transcript with timestamps (YouTube auto-captions or manual subtitles)
- Detects visual references in the text ("look at this diagram", "as you can see here")
- Extracts frames at those timestamps for context
- Presents transcript with embedded images for analysis
Requirements
macOS
brew install yt-dlp ffmpeg
Linux (Ubuntu/Debian)
sudo apt install ffmpeg
pip install yt-dlp
Linux (Arch)
sudo pacman -S yt-dlp ffmpeg
Instructions for Claude
When the user invokes /youtube-transcript <url>:
Step 1: Check Dependencies
command -v yt-dlp >/dev/null 2>&1 || echo "MISSING: yt-dlp"
command -v ffmpeg >/dev/null 2>&1 || echo "MISSING: ffmpeg"
If missing, show installation instructions for the user's platform.
Step 2: Create Output Directory
Use the scratchpad directory for output:
# Extract video ID from YouTube URL (POSIX-compatible, works on macOS and Linux)
# Handles: youtube.com/watch?v=ID, youtu.be/ID, youtube.com/embed/ID
URL="<url>"
VIDEO_ID=$(echo "$URL" | sed -E 's/.*[?&]v=([^&]+).*/\1/;s|.*/embed/([^?/]+).*|\1|;s|.*youtu\.be/([^?/]+).*|\1|')
OUTPUT_DIR="<scratchpad>/youtube-${VIDEO_ID}"
mkdir -p "${OUTPUT_DIR}/frames"
Step 3: Download Transcript
cd "${OUTPUT_DIR}"
# Try auto-generated subtitles first, fall back to manual
yt-dlp --write-auto-sub --sub-lang en,de --skip-download --convert-subs srt -o "transcript" "<url>" 2>/dev/null || \
yt-dlp --write-sub --sub-lang en,de --skip-download --convert-subs srt -o "transcript" "<url>"
Step 4: Analyze for Visual References
Read the transcript and identify timestamps where visual content is referenced. Look for patterns:
German:
- "schau(t)? (mal )?(hier|das)"
- "(dieses|das|dieser) (Diagramm|Bild|Schema|Chart|Graph|Screen|Slide)"
- "wie (du|ihr|Sie) (hier )?(siehst|sehen)"
- "auf (dem|diesem) (Bildschirm|Screen|Slide)"
- "hier sehen wir"
What ships with it
1 file 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.

youtube-transcript is a skill published in the GitHub repository b33eep/claude-code-setup (57 stars, last pushed 11d ago), licensed MIT. It adds 30 tokens to every session and 1,501 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
