A writing tool that turns a video transcript into a YouTube title, description, timecodes, and hashtags. It follows specified style rules for the text.

Use it to prepare YouTube metadata from a transcript, including chapter timecodes and hashtags. It can also work from uploaded video or audio after transcription.

It removes the need to pull the main points and structure out of a transcript by hand. It also keeps titles and descriptions consistent with the chosen writing style.

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	$0.00019	$0.01541
Opus 5	$0.00010	$0.00771
Sonnet 5	$0.00004	$0.00308
Haiku 4.5	$0.00002	$0.00154

Security

Grade A, and why

youtube-seo 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/extract-audio.sh), 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.

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.

Workflow

Step 1: Get transcript

If user provides video/audio file:

# Extract audio if needed (video → audio)
ffmpeg -i video.mp4 -vn -acodec libmp3lame audio.mp3

# Transcribe via OpenAI Whisper API
{skillsDir}/openai-whisper-api/scripts/transcribe.sh audio.mp3 --language ru --json --out transcript.json

If user provides transcript text: Use directly.

Step 2: Analyze transcript

Identify main topic and goal
Extract key insights, numbers, facts
Map narrative structure (for timecodes)
Determine content type:
- Tutorial → focus on value and steps
- Case study / research → focus on results and insights
- Review / comparison → focus on comparison and choice
- Interview → focus on expert and their opinion

Step 3: Generate metadata

Style Guide

First person (as channel author)
Tone: sincere, professional, not pushy
ONE emoji maximum in entire description
Avoid clichés: "В этом видео я расскажу..."
Natural keyword integration, no spam

Target Keywords (use contextually)

Автоматизация, n8n, AI-агент
Искусственный интеллект / AI
Промпт / prompt engineering
Additional keywords from transcript content

Avoid (YouTube demonetization triggers)

Violence, weapons, drugs, gambling
Forex/crypto (unless educational)
Profanity, discrimination
Misleading clickbait
Pushy "подпишись/лайкни" — use neutral alternatives

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.
