Frequently asked questions

How many pages can the Site Audit skill crawl?

The skill crawls up to 500 pages per run by default. You can adjust the crawl depth and page limit by passing flags when you invoke the command. For larger sites, run it against specific subdirectories.

Does the Site Audit check Core Web Vitals?

The Site Audit flags page speed signals like large images and render-blocking resources, but for detailed CWV data use the Core Web Vitals Analyzer skill (/cwv-check). The two skills complement each other.

Can I run the Site Audit on staging environments?

Yes. Point it at any accessible URL, including localhost, staging domains, or password-protected environments if you provide credentials. This is useful for catching issues before deployment.

What output format does the Site Audit produce?

The skill outputs a structured markdown report by default. You can also request CSV or JSON output for importing into spreadsheets or project management tools.
