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 | $0.00037 | $0.03645 |
| Opus 5 | $0.00018 | $0.01822 |
| Sonnet 5 | $0.00007 | $0.00729 |
| Haiku 4.5 | $0.00004 | $0.00364 |
Grade A, and why
youtube-title-creator 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.

YouTube Title & Thumbnail Creator
Purpose
Generate YouTube titles and thumbnails with a high degree of complementarity that achieve 6%+ click-through rates using the framework fitting method: extract your concept, match to 119 proven formulas ranked by performance, generate variations, select best.
Core Philosophy: Good titles follow proven frameworks. The skill is in matching your concept to the delivery mechanism that amplifies it best.
When to Use This Skill
Use this skill when you need to:
- Create YouTube titles for podcast episodes or educational videos
- Generate thumbnail text that complements titles
- A/B test title variations for same content
Do NOT use for:
- Blog post headlines (use
hook-and-headline-writinginstead) - Social media captions (use
social-caption-writerinstead) - Newsletter subject lines (use
hook-and-headline-writinginstead)
Key Principles
The Framework Fitting Method
Extract your content concept → Review ALL applicable frameworks → Test the fit → Generate volume → Select best.
Critical Rule: Avoid First-Match Bias Do NOT default to first framework that seems to fit. The best framework might not be the obvious one.
The Complementarity Principle
Title + thumbnail work TOGETHER, not repeat each other.
Example:
- ❌ Title: "Five Productivity Myths" + Thumbnail: "Five Productivity Myths"
- ✅ Title: "Five Productivity Myths" + Thumbnail: "You're doing it wrong"
Universalization Strategy (Andrew Muto - July 8)
"Every word after your sexy hook is a filter to lessen the audience."
Examples:
- ❌ "Five Productivity Myths Every Entrepreneur Believes" (filters to entrepreneurs only)
- ✅ "Five Productivity Myths" (anyone interested in productivity)
- ❌ "What to Do When Your Team Doesn't Respect You" (filters to managers)
- ✅ "How to Handle Disrespect at Work" (universalized)
When to narrow: When targeting specific audience is strategic goal. Otherwise, broaden.

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.

youtube-title-creator is a skill published in the GitHub repository cdeistopened/skill-stack (27 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 3,645 once invoked, about $0.0002 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.
