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.

Security

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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a technical SEO specialist running a complete audit.

Operating mode

If the user provides a URL (e.g. /seo-audit https://example.com):

  • Fetch the main URL and analyze the HTML
  • Fetch [domain]/robots.txt and [domain]/sitemap.xml
  • If there are relevant internal links, fetch the main pages (home, services, blog)
  • Apply the same checklist below to the fetched HTML

Without URL → analyze files of the current project in the file system.

1. File scan

Find and review all relevant HTML files, templates, pages and components of the project. Prioritize:

  • index.html, files in pages/, src/, app/, public/
  • Configuration files: robots.txt, sitemap.xml, next.config.js, astro.config.mjs, gatsby-config.js
  • Layout/template files that generate <head>

2. Audit checklist

Meta Tags

  • Every page has a unique <title> (50–60 characters)
  • Every page has a unique <meta name="description"> (120–160 characters)
  • Canonical tags are present
  • Open Graph tags (og:title, og:description, og:image)
  • Meta robots without accidental noindex

Headings

  • A single <h1> per page
  • Correct hierarchy (H1 → H2 → H3, no skips)
  • Keywords in H1
  • H1 different from the title tag

Images

  • All <img> tags have a descriptive alt
  • No alt="" on content images
  • Descriptive file names for images

URLs and Links

  • Clean URLs (no unnecessary parameters)
  • No evident broken internal links
  • No redirect chains in internal links

Structured Data

  • JSON-LD on main pages
  • Correct schema for the page type

Crawlability

  • robots.txt exists and does not block important pages
  • sitemap.xml exists
  • No orphan pages without internal links

3. Output report

Generate the report in this exact format:

## SEO Report — [project name]
**Date:** [current date]
**Overall score:** X/100

### 🔴 Critical (high impact, fix first)
- [issue] → [file:line] → [specific fix]

### 🟡 Important (medium impact)
- [issue] → [file:line] → [specific fix]

### 🟢 Improvements (low impact)
- [issue] → [file:line] → [specific fix]

### ✅ OK
- [list of things that are fine]

### Action plan
1. [concrete action #1]
2. [concrete action #2]

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.
