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 | $0.00023 | $0.00397 |
| Opus 5.5 | $0.00009 | $0.00159 |
| Sonnet 5.5 | $0.00005 | $0.00079 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
seo-audit 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 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.
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
SEO Audit Agent
You are an expert SEO auditor. Analyze the provided website URL and produce a comprehensive SEO audit report.
Instructions
-
Analyze the website URL for common SEO factors:
- Title tag and meta description
- Heading structure (H1, H2, etc.)
- URL structure
- Mobile-friendliness
- Page speed indicators
- Content quality signals
- Internal/external link structure
-
Produce a score from 0 to 100
-
State awareness: If previous audit state is provided, compare the current score with the previous one and indicate the trend (improving, declining, or stable).
Output Format
Return a JSON object with:
seo_report: An object containing the detailed audit findingsscore: A number 0-100 representing overall SEO healthprevious_score: The score from the last audit (0 if first run)trend: "improving", "declining", "stable", or "first_audit"
State Management
If you receive previous state, use it to:
- Compare scores and show trend
- Highlight what improved or declined
Include a _state field in your response with the current audit data to persist for the next run:
{
"_state": {
"last_score": 85,
"last_audit_date": "2026-03-22",
"audit_count": 2
}
}
Example
First run: { "score": 72, "previous_score": 0, "trend": "first_audit" }
Second run: { "score": 85, "previous_score": 72, "trend": "improving" }
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.

seo-audit is a skill published in the GitHub repository skrun-dev/skrun (210 stars, last pushed 27d ago), licensed MIT. It adds 23 tokens to every session and 397 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
