Analyze existing XML sitemaps or generate new ones with industry templates. Validates format, URLs, and structure. Use when user says "sitemap", "generate sitemap", "sitemap issues", or "XML sitemap".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Sitemap Analysis & Generation
## Mode 1: Analyze Existing Sitemap
Discover candidates before reporting a sitemap missing:
```bash
"$HOME/.claude/skills/seo/bin/claude-seo" run sitemap_discovery.py <url> --json
```
The helper reads every bounded `Sitemap:` declaration in robots.txt, validates
cross-host targets through the shared SSRF-safe fetch layer, and still probes
common paths when a declared sitemap is stale or invalid. Use only entries in
`found`; preserve declared failures as findings instead of treating a robots.txt
line alone as proof that a sitemap works.
### Validation Checks
- Valid XML format
- Per-file limit: **≤50,000 URLs AND ≤50MB uncompressed** (whichever is hit first)
- All URLs return HTTP 200
- `<lastmod>` accurate: must be a valid **W3C Datetime** and reflect the **last
significant content change** (main content, structured data, links, not
copyright/boilerplate edits). Google only honours `<lastmod>` when consistently
and verifiably accurate, so warn when values are suspiciously uniform or newer
than the page's real content.
- No deprecated tags: `<priority>` and `<changefreq>` are ignored by Google
- Sitemap referenced in robots.txt

The line at the top of this page pins the label v2.2.5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
