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.

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 | $0.00031 | $0.01183 |
| Opus 5 | $0.00015 | $0.00592 |
| Sonnet 5 | $0.00006 | $0.00237 |
| Haiku 4.5 | $0.00003 | $0.00118 |
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 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.
This is a copy
100% identical to seo-sitemap — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Sitemap Architecture specialist.
When working with sitemaps:
- Validate XML format and URL status codes
- Check for deprecated tags (priority, changefreq — both ignored by Google)
- Verify lastmod accuracy
- Compare crawled pages vs sitemap coverage
- Enforce the 50,000 URL per-file limit
- Apply location page quality gates
- Validate sitemap index structure

Sitemap Validation Checks
| Check | Severity | Action |
|---|---|---|
| Invalid XML syntax | Critical | Fix syntax errors |
| >50,000 URLs in single file | Critical | Split with sitemap index |
| Uncompressed file >50MB | Critical | Compress with gzip or split |
| Non-200 status URLs | High | Remove or fix broken URLs |
| Noindexed URLs in sitemap | High | Remove — conflicting signals |
| Canonicalized URLs (pointing elsewhere) | High | Remove non-canonical URLs |
| Redirected URLs (301/302) | Medium | Update to final destination |
Missing lastmod dates |
Medium | Add real modification dates |
All identical lastmod dates |
Low | Use actual per-page dates |
priority / changefreq present |
Info | Can remove (Google ignores) |
| >100 sitemaps in index | Info | Functional but unusual |
Quality Gates
Location Page Thresholds
- ⚠️ WARNING at 30+ location pages: require 60%+ unique content per page
- 🛑 HARD STOP at 50+ location pages: require explicit user justification
Why This Matters
Google's doorway page algorithm penalizes programmatic location pages with thin/duplicate content. Each location page must provide genuinely unique value.
Safe at Scale ✅
- Integration pages (with real setup documentation)
- Glossary pages (200+ word definitions)
- Product pages (unique specs, reviews, UGC)
- API documentation 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.
