yt-packagingCreate optimized YouTube titles and thumbnail concepts for maximum CTR.
Yt Packaging is an agent skill from jeremylongshore/tons-of-skills-marketplace. Create optimized YouTube titles and thumbnail concepts for maximum CTR. Use this skill whenever the user says "title ideas", "thumbnail concepts", "package this video", "CTR optimization", "title options", "packaging", or has an approved brief and needs to finalize the title and thumbnail direction before outlining. Packaging determines whether viewers click. Use when working with yt packaging. Trigger with 'yt', 'packaging'.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code
It works with YouTube. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
WebSearchReadWriteFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Yt Packaging loads about 1.7k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 721 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/yt-packaging/SKILL.md (or your agent's skills folder).You are creating the title and thumbnail concept for a YouTube video. Packaging is where CTR is determined - the title and thumbnail are the single biggest factor in whether a video succeeds.
You need from the user:
video-brief-yt-packaging.md from the working directory or get the brief details from the userBefore writing titles, research what's already out there:
Create 5-10 title options across different strategies:
Strategy A: Direct Benefit Focus on what the viewer will be able to DO.
Strategy B: Curiosity Gap Create intrigue without being misleading.
Strategy C: Authority/Definitive Position as THE resource.
Strategy D: Trending/Urgency For update videos and time-sensitive content.
For each title:
Create 3-5 thumbnail concepts. Each concept should include:
Visual description:
For each concept:
For the top 2-3 title + thumbnail combos, suggest A/B testing variants:
Present all options in a structured format:
## Title Options
| # | Title | Strategy | Keywords | Length |
|---|-------|----------|----------|--------|
| 1 | [title] | Direct Benefit | [keywords] | 48 chars |
| 2 | [title] | Curiosity Gap | [keywords] | 52 chars |
...
## Thumbnail Concepts
### Concept A: [Name]
- Visual: [description]
- Text overlay: "[text]"
- Complements titles: #1, #3
### Concept B: [Name]
- Visual: [description]
- Text overlay: "[text]"
- Complements titles: #2, #4
## Recommended Combo
Title #[X] + Thumbnail Concept [Y] because [reasoning]"Pick your title and thumbnail direction."
This is a mandatory human checkpoint.

SKILL.md names no scripts, command-line tools or credentials: Yt Packaging is instructions for the agent only. Its frontmatter pre-approves these tools: WebSearch, Read, Write. Compatibility (from SKILL.md): Designed for Claude Code.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Yt Packaging is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Yt Packaging: Markitdown (ImCa0/just-laws, 781 stars), Banner Design System (nextlevelbuilder/ui-ux-pro-max-skill, 135k stars), Agent Reach (Panniantong/Agent-Reach, 95k stars) and Last30days (mvanhorn/last30days-skill, 64k stars).
