seo-sitemap is a skill for Claude Code from hashgraph-online/awesome-codex-plugins. It costs 49 tokens per session (973 once invoked), scanned A, original, Apache-2.0.

A tool for checking existing XML sitemaps or creating new ones. An XML sitemap is a file that lists website URLs so search engines can discover and assess them.

In plain words
What is it for?
Use it to validate sitemap XML, compare listed URLs with crawled pages, check robots.txt references, or generate sitemaps for different content types.
Why use it?
It finds invalid URLs, missing pages, redirects, blocked or non-canonical pages, and files that exceed the sitemap size limit. It also helps create correctly structured sitemap files.

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-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 2d 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.

Sitemap Analysis & Generation

Mode 1: Analyze Existing 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

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)

Mode 2: Generate New Sitemap

Process

  1. Ask for business type (or auto-detect from existing site)
  2. Load industry template from ../seo-plan/assets/ directory
  3. Interactive structure planning with user
  4. Apply quality gates:
    • ⚠️ WARNING at 30+ location pages (require 60%+ unique content)
    • 🛑 HARD STOP at 50+ location pages (require justification)
  5. Generate valid XML output
  6. Split at 50k URLs with sitemap index
  7. Generate STRUCTURE.md documentation

Safe Programmatic Pages (OK at scale)

✅ Integration pages (with real setup docs) ✅ Template/tool pages (with downloadable content) ✅ Glossary pages (200+ word definitions) ✅ Product pages (unique specs, reviews) ✅ User profile pages (user-generated content)

Penalty Risk (avoid at scale)

❌ Location pages with only city name swapped ❌ "Best [tool] for [industry]" without industry-specific value ❌ "[Competitor] alternative" without real comparison data ❌ AI-generated pages without human review and unique value

Changes

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.
