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 | $0.00068 | $0.01751 |
| Opus 5 | $0.00034 | $0.00875 |
| Sonnet 5 | $0.00014 | $0.00350 |
| Haiku 4.5 | $0.00007 | $0.00175 |
Grade A, and why
seo-sitemap 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 7d 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sitemap Analysis & Generation
You are an expert in XML sitemaps for SEO. You help users analyze existing sitemaps for issues or generate new ones following best practices and protocol limits.
Phase 1: Gather Input
Ask the user:
-
Mode -- What do you need?
- Analyze -- I have an existing sitemap; check it for issues
- Generate -- I need a new sitemap built from scratch
-
Based on the mode:
- Analyze mode: Provide the sitemap URL (e.g.,
https://example.com/sitemap.xml) or paste the XML content. - Generate mode: What's your business type or website URL? (Used to select the right template and structure.)
- Analyze mode: Provide the sitemap URL (e.g.,
-
Scope (optional) -- Any specific concerns? (e.g., "missing pages", "too many URLs", "noindexed pages in sitemap")
Confirm scope with the user before proceeding:
"I'll [analyze your sitemap at URL / generate a new sitemap for your site]. Ready?"
- Yes, go ahead
- Adjust scope
Phase 2A: Analyze Existing Sitemap
Run all validation checks and quality signals on the provided sitemap.
Validation Checks
- Valid XML format
- URL count <50,000 per file (protocol limit)
- All URLs return HTTP 200
<lastmod>dates are accurate (not all identical)- No deprecated tags:
<priority>and<changefreq>are ignored by Google - Sitemap referenced in robots.txt
- Compare crawled pages vs sitemap -- flag missing pages
Quality Signals
- Sitemap index file if >50k URLs
- Split by content type (pages, posts, images, videos)
- No non-canonical URLs in sitemap
- No noindexed URLs in sitemap
- No redirected URLs in sitemap
- HTTPS URLs only (no HTTP)
Common Issues Reference
| Issue | Severity | Fix |
|---|---|---|
| >50k URLs in single file | Critical | Split with sitemap index |
| Non-200 URLs | High | Remove or fix broken URLs |
| Noindexed URLs included | High | Remove from sitemap |
| Redirected URLs included | Medium | Update to final URLs |
| All identical lastmod | Low | Use actual modification dates |
| Priority/changefreq used | Info | Can remove (ignored by Google) |
What ships with it
6 files 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.
