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.

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 | $0.00020 | $0.00327 |
| Opus 5 | $0.00010 | $0.00163 |
| Sonnet 5 | $0.00004 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
yt-dlp scanned grade A 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says
yt-dlp
Download YouTube videos, audio, and subtitles/transcripts.
Setup
Check if yt-dlp is installed, and download it if not:
if ! command -v yt-dlp &>/dev/null && [ ! -f ~/yt-dlp ]; then
curl -sL https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp -o ~/yt-dlp && chmod +x ~/yt-dlp
fi
Then use ~/yt-dlp (or just yt-dlp if installed globally).
Examples
Download subtitles/transcript:
~/yt-dlp --write-auto-sub --sub-lang en --skip-download -o "/tmp/%(id)s" <url>
Download audio only:
~/yt-dlp -x --audio-format mp3 -o "/tmp/%(title)s.%(ext)s" <url>
Download video:
~/yt-dlp -o "/tmp/%(title)s.%(ext)s" <url>
Get video info (title, duration, description):
~/yt-dlp --print title --print duration_string --print description --no-download <url>
Notes
- Subtitles are saved as
.vttfiles - read them to get the transcript - Use
/tmp/for downloads to avoid cluttering the working directory
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.
