SEO Sitemap Skill for Claude

Sitemap review

Input

A sitemap URL/XML document or an explicit inventory of intended canonical URLs.

Evidence and runtime

If a skill-resource reader fails to open a linked supporting file, try the

available file or execution tool using the installed plugin root returned by

the host or resolved from this skill's location. Do not hardcode a home folder,

version, or working directory. Distinguish a failed reader call from an absent

file, and files actually attempted from files not attempted. Report a resource

as unavailable only after the supported access paths have failed. If no file

or execution access is available, continue within the evidence you can read

and state that limit.

Read the operating contract when this

workflow is selected. Use runtime and data paths

when choosing a tool or handling missing data. Recheck relevant

search facts and primary sources

before date-sensitive claims. For a quantitative diagnostic, read

scoring; unavailable categories stay unknown.

Supporting resources

Read only the resources needed for the selected part of this task:

• discovery and coverage reconciliation.
• sitemap versus supplied crawl evidence.

Workflow

• Discover sitemap candidates from observed robots Sitemap declarations, linked indexes and common paths when browsing can inspect them. A declaration alone is not proof of a working sitemap.
• Use ../../scripts/validate_sitemap.py when a supplied XML file and Python are available. Record index children that were not fetched.
• Check protocol namespace, absolute locations, exact duplicates, date syntax, the 50,000-entry and 50 MiB uncompressed limits. Treat priority/changefreq as ignored hints for Google.
• Join entries with separately measured status, canonical and index-control data. XML by itself cannot establish that entries return 200 or are indexable.
• Use lastmod only for real significant content changes. Do not refresh every URL date to the current day without evidence.
• Generate XML from known intended URLs, escaping values and splitting at protocol limits. Keep coverage gaps explicit rather than inventing site URLs.

Deliverable

A sitemap findings report or generated sitemap/index files with URL count, validation scope and a list of untested destinations.

Boundary

Cross-host sitemap arrangements can be valid when authorized; investigate their setup. Extension-specific image/video/news requirements need their own current checks.
