A skill for transcribing and summarizing videos and podcasts from supported websites or direct media links. It can use subtitles when available or speech recognition when they are not.

Use it with YouTube, Bilibili, X videos, supported podcast pages, and direct audio or video URLs. It is for producing transcripts and summaries from those recordings.

It removes the need to listen to or watch the entire recording manually before getting its contents. It also provides a path for sources that have no subtitles.

Token cost

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	$0.00035	$0.02752
Opus 5.5	$0.00014	$0.01101
Sonnet 5.5	$0.00007	$0.00550
Haiku 4.5	$0.00003	$0.00275

Security

Grade A, and why

video 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 18d 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.

Makes network callslowCapability

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

Trigger

Auto-triggered when a media URL is detected:

YouTube: youtube.com, youtu.be
Bilibili: bilibili.com, b23.tv
X/Twitter: x.com, twitter.com (tweets with video)
Xiaoyuzhou: xiaoyuzhoufm.com
Apple Podcasts: podcasts.apple.com
Direct: .mp3, .mp4, .m3u8, .m4a, .webm

Pipeline

Step 0: Detect Media Type

URL Pattern	Type	Pipeline
`xiaoyuzhoufm.com/episode/`	Podcast	→ Step 1b (Xiaoyuzhou)
`podcasts.apple.com`	Podcast	→ Step 1c (Apple)
`bilibili.com`, `b23.tv`	Video	→ Step 1d (Bilibili API)
`.mp3`, `.m4a` direct link	Audio	→ Step 2b (direct download)
Other	Video	→ Step 1a (subtitle extraction)

Step 1a: Video — Extract Subtitles

# Clean up temp files
rm -f /tmp/media_sub*.vtt /tmp/media_audio.mp3 /tmp/media_transcript*.json /tmp/media_segment_*.mp3 2>/dev/null || true

# YouTube (prefer English, fallback Chinese)
yt-dlp --skip-download --write-auto-sub --sub-lang "en,zh-Hans" -o "/tmp/media_sub" "VIDEO_URL"

# Bilibili
yt-dlp --skip-download --write-auto-sub --sub-lang "zh-Hans,zh" -o "/tmp/media_sub" "VIDEO_URL"

Check for subtitles:

ls /tmp/media_sub*.vtt 2>/dev/null

Has subtitles → Read VTT content, skip to Step 3
No subtitles → Step 2a (download audio)

Step 1b: Xiaoyuzhou (小宇宙) — Extract Audio URL

# Extract CDN direct link from __NEXT_DATA__
# Xiaoyuzhou is a Next.js SPA, but initial HTML contains audio URL in __NEXT_DATA__
AUDIO_URL=$(curl -sL -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36" \
  "EPISODE_URL" \
  | grep -oE 'https://media\.xyzcdn\.net/[^"]+\.(m4a|mp3)' \
  | head -1)

echo "Audio URL: $AUDIO_URL"

# Download audio
curl -L -o /tmp/media_audio.mp3 "$AUDIO_URL"

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.
