2. Core Architecture

The core architecture introduces several new components to WordPress that enable AI agent functionality while maintaining backwards compatibility.

2.1 WP_Agent_Controller

The central orchestration layer for all AI agents in WordPress.

class WP_Agent_Controller {
    private $registered_agents = [];
    private $agent_capabilities = [];
    private $agent_memory;        // Persistent context/memory store
    private $tool_registry;       // Available actions agents can take
    private $guardrails;          // Safety constraints
    
    /**
     * Register an agent with the system
     */
    public function register_agent( string $agent_id, array $capabilities, string $scope ): bool;
    
    /**
     * Dispatch a task to appropriate agent(s)
     */
    public function dispatch_task( string $task, array $context, array $constraints ): WP_Agent_Response;
    
    /**
     * Get a decision from a specific agent
     */
    public function get_agent_decision( string $agent_id, string $prompt, array $tools ): WP_Agent_Decision;
    
    /**
     * Execute an agent action with guardrails
     */
    public function execute_action( string $action, array $params, string $agent_id ): WP_Agent_Result;
}

2.2 Agent Decision Hooks

Extension of WordPress’s action/filter system for AI decision-making.

// Traditional WordPress
do_action( 'save_post', $post_id );
$content = apply_filters( 'the_content', $content );

// Agentic Plugin - New paradigm
do_agent_decision( 'should_publish_post', [
    'post'    => $post,
    'context' => $editorial_context,
    'tools'   => ['publish', 'schedule', 'request_review', 'improve_content']
]);

$content = apply_agent_transform( 'personalize_content', $content, [
    'user_context' => wp_agent_get_user_context(),
    'constraints'  => ['maintain_seo', 'preserve_structure']
]);

2.3 Agent Memory & Context API

Persistent memory system for maintaining context across sessions.

global $wp_agent_memory;

// Store learned information
$wp_agent_memory->store( 'user_preferences', $user_id, $learned_preferences );
$wp_agent_memory->store( 'content_patterns', $site_id, $patterns );

// Recall information
$preferences = $wp_agent_memory->recall( 'user_preferences', $user_id );
$history = $wp_agent_memory->get_conversation_history( $session_id );

// Memory management
$wp_agent_memory->forget( 'user_preferences', $user_id ); // GDPR compliance
$wp_agent_memory->export( $user_id ); // Data portability

2.4 Tool Registry System

Standardized interface for agent-callable functions.

class WP_Agent_Tool_Registry {
    
    public function register_tool( string $name, array $config ): bool {
        // $config structure:
        // [
        //     'callback'    => callable,
        //     'description' => string,      // For agent understanding
        //     'parameters'  => array,       // JSON Schema format
        //     'returns'     => string,      // Return type description
        //     'requires'    => array,       // Required capabilities
        //     'guardrails'  => array,       // Safety constraints
        // ]
    }
    
    public function get_tools_for_agent( string $agent_id ): array;
    
    public function execute_tool( string $name, array $params, string $agent_id ): mixed;
}
