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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.02544 |
| Opus 5.5 | $0.00036 | $0.01018 |
| Sonnet 5.5 | $0.00018 | $0.00509 |
| Haiku 4.5 | $0.00009 | $0.00254 |
Grade A, and why
on-page-seo-checker scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

On-Page SEO Checker
This skill audits the structural on-page SEO signals a single page controls and provides actionable, prioritized recommendations.
What This Skill Does
Audits structural on-page signals (title tag, meta description, header structure, keyword placement, internal/external links, images) with scored results and prioritized fix recommendations. For E-E-A-T and publish-readiness scoring, hand off to content-quality-auditor; for crawl, indexing, and Core Web Vitals, use technical-seo-checker.
Quick Start
Start with one of these prompts, then finish with the standard handoff summary from Skill Contract.
Audit a Single Page
Audit the on-page SEO of [URL]
Check SEO issues on this page targeting [keyword]: [URL/content]
Compare Against Competitors
Compare on-page SEO of [your URL] vs [competitor URL] for [keyword]
Audit Content Before Publishing
Pre-publish SEO audit for this content targeting [keyword]: [content]
Site-Wide / Bulk Audit (5+ URLs)
For content category batches (e.g., "audit all 40 blog posts"), switch to bulk mode — group URLs by cluster template, sample 2-3 per cluster, report pattern-level findings + portfolio priority:
Bulk audit: all 40 blog posts on example.com/blog/
Pre-publish audit for these 6 articles: [URLs]
See references/bulk-audit-playbook.md for the full workflow (cluster classification, sampling, extrapolation, portfolio priority, template suggestions).
Skill Contract
Expected output: a scored diagnosis, prioritized repair plan, and a short handoff summary ready for memory/seo-geo/tune/on-page-seo-checker/.
- Reads: the page URL or HTML, target keyword, page type, competitor URLs, and symptoms.
- Writes: a user-facing audit or optimization plan plus a reusable summary that can be stored under
memory/seo-geo/tune/on-page-seo-checker/. - Promotes: blocking defects, repeated weaknesses, fix priorities, and pending decisions to
memory/open-loops.md. - Done when: every on-page element has a /10 score with evidence; fixes are ranked by impact (P0/P1/P2); an overall score and handoff summary are produced.
- Primary next skill: use the
Next Best Skillbelow when the repair path is clear.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
