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 | $0.00096 | $0.02120 |
| Opus 5 | $0.00048 | $0.01060 |
| Sonnet 5 | $0.00019 | $0.00424 |
| Haiku 4.5 | $0.00010 | $0.00212 |
Grade A, and why
seo-audit 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 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.

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

SEO Audit
Identify SEO issues and provide actionable recommendations to improve organic search performance.
Initial Assessment
Product context: If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it first and tailor output to it; only ask for what it doesn't cover.
Before auditing, understand:
- Site Context — site type (SaaS, e-commerce, blog, etc.); primary business goal for SEO; priority keywords/topics
- Current State — known issues or concerns; current organic traffic level; recent changes or migrations
- Scope — full site or specific pages; technical + on-page or one focus area; access to Search Console / analytics
Audit Framework
Schema Markup Detection Limitation
web_fetch and curl cannot reliably detect structured data / schema markup. Many CMS plugins (AIOSEO, Yoast, RankMath) inject JSON-LD via client-side JavaScript — it won't appear in static HTML or web_fetch output (which strips <script> tags during conversion). Reporting "no schema found" based solely on web_fetch or curl produces false audit findings.
To accurately check schema markup, use one of:
- Browser tool — render the page and run:
document.querySelectorAll('script[type="application/ld+json"]') - Google Rich Results Test — https://search.google.com/test/rich-results
- Screaming Frog export — if the client provides one, use it (SF renders JavaScript)
Priority Order
- Crawlability & Indexation (can Google find and index it?)
- Technical Foundations (is the site fast and functional?)
- On-Page Optimization (is content optimized?)
- Content Quality (does it deserve to rank?)
- Authority & Links (does it have credibility?)
Technical SEO Audit
Crawlability
Robots.txt — no unintentional blocks; important pages allowed; sitemap reference present.
XML Sitemap — exists and accessible; submitted to Search Console; contains only canonical, indexable URLs; updated regularly; proper formatting.
What ships with it
3 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.

seo-audit is a skill published in the GitHub repository rajitsaha/100xprism (10 stars, last pushed 12d ago), licensed MIT. It adds 96 tokens to every session and 2,120 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
