wp-performance

name	wp-performance
description	Use when investigating or improving WordPress performance (backend-only agent): profiling and measurement (WP-CLI profile/doctor, Server-Timing, Query Monitor via REST headers), database/query optimization, autoloaded options, object caching, cron, HTTP API calls, and safe verification.
compatibility	Targets WordPress 7.0+ (PHP 7.4.0+). Backend-only agent; prefers WP-CLI (doctor/profile) when available.

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.

Inputs required

• Environment and safety: dev/staging/prod, any restrictions (no writes, no plugin installs).
• How to target the install:
  • WP root --path=<path>
  • (multisite/site targeting) --url=<url>
• The performance symptom and scope:
  • which URL/REST route/admin screen
  • when it happens (always vs sporadic; logged-in vs logged-out)

Procedure

0) Guardrails: measure first, avoid risky ops

1. Confirm whether you may run write operations (plugin installs, config changes, cache flush).
2. Pick a reproducible target (URL or REST route) and capture a baseline:
