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.

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 | $0.00060 | $0.03026 |
| Opus 5 | $0.00030 | $0.01513 |
| Sonnet 5 | $0.00012 | $0.00605 |
| Haiku 4.5 | $0.00006 | $0.00303 |
Grade A, and why
seo-content-optimization 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 10d 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 Content Optimization
Audit-and-fix workflow for improving search rankings on Magnus's content sites. This is the "optimize what exists" counterpart to /content-strategy's "what to write next."
Sites in scope: magnus919.com (Hugo), rdumesh.org (Ghost), groktop.us (Ghost Pro), southeastme.sh (Ghost)
Signals to Run This
- User says "we're not ranking for X" or "SEO is bad"
- User asks to audit a site's search presence
- User mentions poor Google visibility for local terms
- As part of site launch / relaunch
Process
1. Audit page titles and meta descriptions
Fetch the site's sitemap to get all published URLs (see content-strategy skill for sitemap-fetching protocol — try bare domain, www subdomain, Ghost split-sitemaps).
For each published page:
- Check the
<title>tag via curlcurl -s https://example.com/page/ | grep -i '<title' - Check meta description
curl -s https://example.com/page/ | grep -i 'name="description"' - Evaluate against:
- Does the title include the primary keyword near the front?
- Does it include location terms (for local sites)?
- Is it under 60 characters (Google display limit)?
- Is the meta description under 160 chars, compelling, and keyword-rich?
2. Audit structured data
Check for existing schema:
// in browser console
document.querySelectorAll('script[type="application/ld+json"]')
For each JSON-LD block, verify:
- Is there an Organization or LocalBusiness schema?
- Does it include
areaServedwith specific cities? - Is there FAQPage schema on FAQ content?
- Is there BreadcrumbList?
- Is Article schema correctly populated?
3. Inject missing schema
Organization schema — site-wide (Ghost Code Injection → ghost_head). The critical fields for local SEO:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Site Name",
"description": "Description with city and keyword signals.",
"url": "https://example.com",
"areaServed": [
{"@type": "City", "name": "City1", "sameAs": "https://en.wikipedia.org/wiki/City1,_NC"},
{"@type": "City", "name": "City2"}
],
"sameAs": [
"https://discord.gg/..."
]
}

What ships with it
1 file 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.
