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-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 7d 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.

Platforms: YouTube SEO

Guides YouTube video and channel optimization for search and discovery. Google now prioritizes YouTube video results in search; YouTube + Reddit comprise ~78% of social media citations in AI Overviews. Title, description, and thumbnail form an interconnected system; channels using systematic keyword strategies see 156% longer view durations, 89% better CTR, and 312% higher search discovery. Use this skill when optimizing videos for YouTube search, Google search, and AI citation. For website-embedded video SEO, see video-optimization.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read Sections 6 (Keywords), 11 (Content Strategy).

Identify:

  1. Video type: Tutorial, review, vlog, Shorts
  2. Target keyword: Primary and secondary
  3. Audience: Subscribers vs casual viewers

Video Titles

Rule Guideline
Length Under 60 characters; mobile may show partial
Keyword Primary keyword in first 5–55 characters
Structure Social proof/authority + emotional trigger + primary keyword
Style Conversational; avoid keyword stuffing
Avoid ALL CAPS except emphasis

Video Descriptions

Rule Guideline
First 2–3 sentences Primary and secondary keywords naturally; meta description under 160 chars
Links Website, store, relevant resources
Readability Natural flow; help search understand topic

Tags

  • Help YouTube understand content; titles and descriptions matter more
  • Use relevant tags; avoid over-optimization

Thumbnails

90% of best-performing videos use custom thumbnails.

Rule Guideline
Contrast High contrast; readable fonts; bold colors
Composition Rule of thirds; simple, uncluttered
Audience Consider subscribers vs casual viewers
Test What works evolves; test styles

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.
