        # Decompose task
        subtasks = self.task_planner.decompose(task)
        
        # Track progress
        progress = Progress(task.id)
        
        for subtask in subtasks:
            # Select agent
            agent = self.agent_selector.select(subtask)
            
            # Execute with memory context
            context = await self.memory.get_context(task.id)
            result = await agent.execute(subtask, context)
            
            # Update memory
            await self.memory.store_result(task.id, result)
            
            # Track progress

                           execution: Execution) -> Pattern:
        # Extract features
        features = self.feature_extractor.extract(execution)
        
        # Generate embedding
        embedding = self.embedder.embed(features)
        
        # Find similar patterns
        similar = self.pattern_store.find_similar(embedding)
        
        # Update or create pattern
        if similar:
            pattern = self.update_pattern(similar[0], execution)
