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 | $0.00030 | $0.03048 |
| Opus 5.5 | $0.00012 | $0.01219 |
| Sonnet 5.5 | $0.00006 | $0.00610 |
| Haiku 4.5 | $0.00003 | $0.00305 |
Grade A, and why
seo-on-page 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 297 lines — stays where its author put it; the contents beside it link to each section on GitHub.
On-Page SEO
When to Activate
Use this skill when optimizing individual pages for search engine visibility: writing or improving title tags, meta descriptions, headings, content structure, internal links, image optimization, or URL structure. Applies to blog posts, product pages, landing pages, category pages, and any page targeting organic search traffic.
First Questions
- What is the target keyword (and its search intent)?
- What currently ranks in the top 10 for this keyword? (analyze the SERP)
- Is this a new page or an optimization of an existing one?
- What page type is it? (blog post, product page, category page, landing page)
- What is the content's primary goal beyond ranking? (conversions, education, link building)
Title Tag Optimization
The title tag is the single most important on-page ranking factor and the primary driver of click-through rate from SERPs.
Rules
- Length: 50-60 characters (Google truncates at ~580px, roughly 60 chars)
- Keyword placement: Primary keyword as close to the beginning as possible
- Unique: Every page must have a unique title tag
- Compelling: The title must earn the click, not just contain the keyword
- Brand: Include brand name at the end for branded searches (optional for long-tail)

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.
