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 5.1 | $0.00102 | $0.00884 |
| Opus 5.5 | $0.00041 | $0.00354 |
| Sonnet 5.5 | $0.00020 | $0.00177 |
| Haiku 4.5 | $0.00010 | $0.00088 |
Grade A, and why
title-tag 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SEO On-Page: Title Tag
Guides optimization of the HTML title tag for search engines and SERP display.
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.
Scope (On-Page SEO)
- Title tag: Primary search snippet; primary keyword near start; unique per page
Length by Language
Google truncates by pixel width (~580–600px desktop), not character count. Character limits are approximate—CJK chars are wider (~2× Latin), so fewer fit in the same pixels.
| Script / Language | Title (chars) | Notes |
|---|---|---|
| Latin (English, Spanish, French, etc.) | 50–60 | ~55 recommended |
| CJK (Chinese, Japanese, Korean) | 25–35 | Full-width chars; 25–30 desktop; 20–28 mobile; use pixel checker when available |
| Cyrillic (Russian, etc.) | 50–55 | Slightly wider than Latin |
| Arabic, Hebrew | 30–40 | RTL; variable width |
Pixel tools: Use a pixel-accurate checker for CJK—font and locale affect display.
Multilingual: Use locale-specific limits; don't translate then truncate. See localization-strategy, translation.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for brand voice and target keywords.
Identify:
- Page type: Homepage, landing, blog, product, etc.
- Primary keyword: Target search query
- Language / script: Apply length rule above
- Brand: Optional brand append at end
Best Practices
| Item | Guideline |
|---|---|
| Length | Per language (see table above); Google truncates beyond ~600px |
| Front-load | Main phrase first; branding at end |
| Keyword | Include primary keyword near the start |
| Unique | One unique title per page |
| Clarity | Match search intent; avoid keyword stuffing |
| Engagement | Numbers, power words, questions can boost CTR ~36% |
| H1 alignment | H1 should align with title; Google may rewrite titles if they mismatch content or intent |
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.
