A tool that turns a YouTube video into an MP4 with French dubbed speech and returns a downloadable cloud-storage link.

Use it to download a YouTube video, translate its speech into French, add synthesized French audio, and upload the result.

It removes the manual work of downloading, transcribing, translating, recording, and replacing the video's audio.

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	$0.00020	$0.00824
Opus 5	$0.00010	$0.00412
Sonnet 5	$0.00004	$0.00165
Haiku 4.5	$0.00002	$0.00082

Measured 11d ago against content hash a628be32e86f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade B, and why

yt_fr_dub scanned grade B 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (run.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

yt_fr_dub (YouTube → French dub MP4)

Takes a YouTube URL, downloads the video, transcribes the original audio, translates to French, synthesizes French speech, and remuxes the new audio into an MP4.

What it does

Pipeline:

Download best video (no audio) + best audio using yt-dlp (cookies + JS challenge support enabled by default).
Enforce max duration: refuses videos longer than 20 minutes (configurable).
Transcribe audio via AI Foundry /openai (gpt-4o-transcribe).
Translate transcript to French via AI Foundry /openai (gpt-5.2).
Synthesize French audio via Azure Speech /speech (SSML, e.g. fr-FR-DeniseNeural).
Remux into MP4.
Upload to Azure Blob and return a SAS URL (default behavior).

Tools used

What ships with it

7 files 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.

Changes

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.
