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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00040 | $0.00330 |
| Opus 5 | $0.00020 | $0.00165 |
| Sonnet 5 | $0.00008 | $0.00066 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
validate-blog-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 12d 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.
What it actually says
Validate Blog SEO
Scope: blog module SEO validation only (frontmatter, canonical, build) — NOT site-wide SEO audit. For GEO, keyword research, or content strategy use marketing-skills.
Pre-publish checklist
-
descriptionis 80–320 characters -
slugis kebab-case and matches filename -
draft: falsefor publish-ready posts - Canonical URL has no trailing slash
- Internal links resolve to existing slugs
- Title is unique among published posts
-
npm run validate:postspasses -
npm run buildsucceeds
Canonical format
- Standalone / subdirectory:
https://{SITE_URL}/blog/{slug} - Subdomain:
https://{SITE_URL}/{slug}
Commands
Run from the repo root:
npm run validate:posts
npm run build
Out of scope
- Site-wide SEO (homepage, product pages, llms.txt, GSC)
- Keyword research, content optimization, or GEO strategy → marketing-skills
- Marketing landing pages or non-blog routes
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.
