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 | $0.00123 | $0.02282 |
| Opus 5 | $0.00062 | $0.01141 |
| Sonnet 5 | $0.00025 | $0.00456 |
| Haiku 4.5 | $0.00012 | $0.00228 |
Grade A, and why
audio-extractor scanned grade A with 0 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 4d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 300 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio Extractor
Extract pure audio from videos and download audio content. Supports format conversion, metadata embedding, and batch playlist processing.
Prerequisites
- Executor: Must use the
remotionexecutor (provides yt-dlp, ffmpeg, deno) - JS Runtime: deno is required for YouTube extraction (yt-dlp 2025+ default). The remotion executor includes deno.
- ffmpeg: Required for audio format conversion and metadata embedding. Included in remotion executor.
Limitations
| Issue | Detail |
|---|---|
| YouTube rate limiting | Server IPs are frequently rate-limited by YouTube. If you get "This content isn't available, try again later", wait ~1 hour or ask the user to upload the audio file directly. |
| YouTube JS runtime | yt-dlp requires deno for YouTube. Without it: No supported JavaScript runtime could be found. |
| Geo-restrictions | Some content may be region-locked. Use --geo-bypass flag. |
| Authentication | Some platforms require cookies. Use --cookies-from-browser or --cookies cookies.txt. |
Fallback strategy: If YouTube download fails, suggest the user upload the audio file directly or provide a direct audio URL.
Quick Start
# Extract audio (best quality, original format)
yt-dlp -x "URL"
# Extract as MP3
yt-dlp -x --audio-format mp3 "URL"
# MP3 with metadata and cover art
yt-dlp -x --audio-format mp3 --embed-metadata --embed-thumbnail "URL"
Audio Formats
Format Selection
| Format | Command | Use Case |
|---|---|---|
| MP3 | --audio-format mp3 |
Universal compatibility |
| M4A/AAC | --audio-format m4a |
Apple devices, good quality/size |
| FLAC | --audio-format flac |
Lossless, archival |
| WAV | --audio-format wav |
Uncompressed, editing |
| OPUS | --audio-format opus |
Best quality/size ratio |
| Vorbis | --audio-format vorbis |
Open source, OGG container |
| Best | --audio-format best |

Quality Control
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.

audio-extractor is a skill published in the GitHub repository dp-archive/archive (1,106 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 123 tokens to every session and 2,282 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
