WP Performance (backend-only)

When to use

Use this skill when:

• a WordPress site/page/endpoint is slow (frontend TTFB, admin, REST, WP-Cron)
• you need a profiling plan and tooling recommendations (WP-CLI profile/doctor, Query Monitor, Xdebug/XHProf, APMs)
• you’re optimizing DB queries, autoloaded options, object caching, cron tasks, or remote HTTP calls

This skill assumes the agent cannot use a browser UI. Prefer WP-CLI, logs, and HTTP requests.
