What is audit-existing-site?

A website health review based only on a live website address. It checks search visibility, content, user experience, and security, then gives a health score, quick improvements, and a longer improvement plan.

Use it to review WordPress, Squarespace, Wix, or custom sites for SEO and answer-engine visibility, copy and content, usability, security, mobile readiness, speed, accessibility, and related concerns.

You may have website problems without knowing whether they come from search settings, unclear writing, difficult navigation, or security issues. This identifies those issues without requiring code, repository, or GitHub access.

Token cost

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	$0.01624
Opus 5.5	$0.00036	$0.00650
Sonnet 5.5	$0.00018	$0.00325
Haiku 4.5	$0.00009	$0.00162

Security

Grade A, and why

audit-existing-site 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 2mo 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.

Audit Existing Site

You already have a website—WordPress, Squarespace, Wix, custom build, doesn't matter. Before you think about rebuilding, let's see what you've actually got.

This skill analyzes your live website without requiring any repo access, GitHub connection, or code handoff. We fetch your site and run a comprehensive 4-part audit: SEO & AEO, Copy & Content, UX, and Security. You get a health score, quick wins, and a roadmap for improvement.

Think of this as a gateway skill. See the value? Then explore how VibeCoding could rebuild or enhance your site from the ground up.

What You Need

A live URL (your existing website, already published on the internet)
That's it. No repo access, no GitHub, no code to share.

The Audit Pipeline

We run 4 specialized audits in sequence, each targeting a different dimension of site health:

1. SEO & AEO Audit

Searches for technical and structural SEO signals:

Meta tags & title tags: Are they present, unique, and keyword-rich?
Open Graph / social sharing tags: Will your site look good when shared?
Heading hierarchy: H1 → H2 → H3 structure (no orphans, no skips)
Schema markup & JSON-LD: Rich snippets for Google
Mobile-friendliness signals: Viewport tags, responsive patterns
Page speed indicators: Core Web Vitals, load time estimates
Alt text on images: Every image described for accessibility and SEO
URL structure: Readable slugs, no parameters, proper trailing slashes

2. Copy & Content Audit

Reviews your actual words and messaging:

Headline effectiveness: Do they hook? Is the benefit clear?
CTA strength and placement: Are calls-to-action specific, urgent, and visible?
Readability score: Target is 6th–8th grade level. Shorter sentences win.
Value proposition clarity: Could a stranger understand your value in 5 seconds?
Microcopy review: Button labels, form fields, error messages, help text
Tone consistency: Is your voice uniform across pages?

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.
