# WP-CLI doctor (`wp doctor`)

Use this for quick “production readiness” checks.

## Install (if missing)

- `wp package install wp-cli/doctor-command`

Docs:

- Default checks: https://make.wordpress.org/cli/handbook/doctor-default-checks/
- Customize checks: https://make.wordpress.org/cli/handbook/guides/doctor/doctor-customize-config/

## Recommended usage

- `wp doctor check`
- `wp doctor list` (to see available checks)

Especially relevant to performance:

- `autoload-options-size` (autoloaded options threshold)
- `constant-savequeries-falsy` / `constant-wp-debug-falsy` (avoid perf-costly debug flags in prod)
- cron checks (count/duplicates)
