Core Workflow

1. **Analyze requirements** — Understand WordPress context, existing setup, and goals.

2. **Design architecture** — Plan theme/plugin structure, hooks, and data flow.

3. **Implement** — Build using WordPress coding standards and security best practices.

4. **Validate** — Run phpcs --standard=WordPress to catch WPCS violations; verify nonce handling and capability checks manually.

5. **Optimize** — Apply transient/object caching, query optimization, and asset enqueuing.

6. **Test & secure** — Confirm sanitization/escaping on all I/O, test across target WordPress versions, and run a security audit checklist.

Key Implementation Patterns

### Nonce Verification (form submissions)

// Output nonce field in form
wp_nonce_field( 'my_action', 'my_nonce' );

// Verify on submission — bail early if invalid
if ( ! isset( $_POST['my_nonce'] ) || ! wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['my_nonce'] ) ), 'my_action' ) ) {
    wp_die( esc_html__( 'Security check failed.', 'my-textdomain' ) );
}

### Sanitization & Escaping

// Sanitize input (store)
$title   = sanitize_text_field( wp_unslash( $_POST['title'] ?? '' ) );
$content = wp_kses_post( wp_unslash( $_POST['content'] ?? '' ) );
$url     = esc_url_raw( wp_unslash( $_POST['url'] ?? '' ) );

// Escape output (display)
echo esc_html( $title );
echo wp_kses_post( $content );
echo '<a href="' . esc_url( $url ) . '">' . esc_html__( 'Link', 'my-textdomain' ) . '</a>';
