Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00039 | $0.04535 |
| Opus 5 | $0.00019 | $0.02268 |
| Sonnet 5 | $0.00008 | $0.00907 |
| Haiku 4.5 | $0.00004 | $0.00453 |
Grade A, and why
seo-audit-full 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.

The opening of the file, as written. The whole thing — 415 lines — stays where its author put it; the contents beside it link to each section on GitHub.
seo-audit-full — Advanced Full SEO Audit
This skill runs a full single-page SEO audit from the seo-audit-full directory.
It does not route to seo-audit when only a URL is provided.
When to Use This Skill
Use seo-audit-full when the user asks for:
- "seo-audit-full"
- "full SEO audit"
- "advanced SEO audit"
- "technical SEO audit"
- "deep audit"
- "comprehensive SEO review"
- "audit everything"
URL-only requests are valid. When external datasets are not supplied, run the full public-signal workflow and clearly note missing data sources in the report.
Input Expected
| Input | Required | Notes |
|---|---|---|
| Page URL | Yes | The primary page to audit |
| Primary keyword | Recommended | Improves content relevance scoring |
| PageSpeed API key | Yes | Required for full audit PageSpeed checks. Ask at the start and do not run PageSpeed without it. |
| Raw HTML or page content | Optional | Enables more accurate content checks when supplied |
| GSC / crawl / analytics data | Optional | Include when supplied, otherwise mark unavailable |
| Competitor benchmark data | Optional | Include when supplied |
At the start of a full audit, ask the user for a PageSpeed Insights API key:
For PageSpeed checks, please provide a Google PageSpeed Insights API key.
Get one here: https://developers.google.com/speed/docs/insights/v5/get-started
Open "Acquiring and using an API key" → "Get a Key".
If you do not provide one, I will stop before running the full audit because
PageSpeed is a required full-audit module.
Do not run seo-audit-full PageSpeed checks without a PageSpeed API key supplied
by --api-key, PAGESPEED_API_KEY, or GOOGLE_PAGESPEED_API_KEY. If the key is
missing, stop and ask the user to configure it instead of rendering a full report
with missing PageSpeed data.

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.
