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.

Security

Grade A, and why

youtube-title-tag-optimizer 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/optimize_title_tags.py), 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.

YouTube Title & Tag Optimizer

Optimize your video title, tags, and description before publishing by analyzing what works for top-ranking videos.

Usage

/youtube-title-tag-optimizer "air fryer recipes"
/youtube-title-tag-optimizer "Python tutorial" --my-title "Learn Python in 10 Minutes"
/youtube-title-tag-optimizer --keyword "home workout" --my-title "Best Home Workout for Beginners 2024"

Instructions

Step 1: Parse Arguments

  • Keyword (required): the topic/keyword to optimize for
  • --my-title "..." (optional): the user's working title to score and improve

Step 2: Get the API Key

Check the user's Claude memory for a YouTube Data API v3 key. If not found, ask:

"I need a YouTube Data API v3 key to analyze ranking videos. You can get one from the Google Cloud Console. Please paste your key."

Step 3: Run the Bundled Script

Run scripts/optimize_title_tags.py — resolve the path relative to this skill's own directory:

YT_API_KEY=API_KEY python3 <skill-dir>/scripts/optimize_title_tags.py "KEYWORD" [--my-title "User Title"]

Dependency: pip3 install google-api-python-client.

The script pulls the top 50 by relevance and top 50 by views, analyzes every title for length, formatting elements, power words and structures, aggregates tag usage, and — when --my-title is given — scores it out of 100 with itemized feedback.

Step 4: Read the Data

reports/data/title-tag-<keyword-slug>-<YYYY-MM-DD>.json

Step 5: Write the Report

Write to the path the script printed:

reports/title-tag-<keyword-slug>-<YYYY-MM-DD>.md

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.
