Wp Performance

What it does

The Wp Performance skill analyzes the speed of a WordPress site, page, or endpoint without requiring access to a browser UI. It identifies performance bottlenecks and suggests actionable improvements for areas like database queries, autoloaded options, object caching, cron tasks, and remote HTTP calls. The skill relies on tools accessible via command line (WP-CLI), logs, and HTTP requests.

When to use it

• When a WordPress site or page is loading slowly (frontend TTFB, admin area, REST API endpoints, WP-Cron).
• To receive recommendations for profiling plans and tooling (e.g., WP-CLI profile/doctor, Query Monitor, Xdebug/XHProf).
• When optimizing database queries, autoloaded options, object caching, cron tasks, or remote HTTP calls is needed.
• For diagnosing performance issues in development, staging, or production environments.

Key capabilities

• Backend-only analysis: Operates without requiring a browser UI.
• WP-CLI utilization: Leverages WP-CLI for profiling and diagnostics (if available).
• Performance report generation: Creates deterministic performance reports using perf_inspect.mjs.
• Diagnostic checks: Runs wp doctor to identify common WordPress configuration issues.
• Profiling: Uses wp profile to analyze time spent in different phases of WordPress execution (bootstrap, main query, template).
• Query Monitor integration: Provides headless access to Query Monitor data via REST API headers and response properties.

Example prompts

• "Analyze the performance of my WordPress site at [URL] using WP-CLI."
• "Run a wp doctor check on my WordPress installation located at [path]."
• "Generate a backend performance report for the admin dashboard, targeting path [path]."

Tips & gotchas

• Environment Restrictions: Be aware of any restrictions in the target environment (e.g., limitations on write operations like plugin installs or configuration changes).
• Baseline Measurement: Always measure baseline performance before making any changes to ensure improvements are tracked accurately.
• WP-CLI Dependency: The skill heavily relies on WP-CLI being available and functional on the WordPress server.
