Wordpress Performance Best Practices
This is a structured ruleset for keeping WordPress code performant, with 34 rules across database queries, caching, assets, and theme development. It's designed for code review and generation, triggering when you're working with WP_Query, hooks, or REST API implementations. The rules are prioritized by impact (database and caching are marked critical, things like cron optimization are lower), which is smart because not all WordPress performance issues matter equally. Each rule has a prefix system and points to detailed markdown files with bad/good code examples. If you're building plugins or themes and want Claude to catch performance antipatterns like post__not_in or hardcoded script tags, this gives it a concrete checklist to work from.
