## Definition
Cognitive Architecture is the design blueprint for structuring an autonomous AI Agent. It defines how memory, planning steps, reflection mechanisms, and external tools interact with the core LLM brain to create a persistent agentic loop.

## Architectural Mechanics & Deep Dive
Cognitive architecture refers to the structural design, memory systems, tools, and decision-making logic that define how an autonomous AI agent thinks and acts. Instead of relying on a single raw LLM call, a cognitive architecture structures the system into components like working memory, long-term vector storage, execution loops, tool registries, and self-reflection modules, mirroring cognitive processes to solve complex tasks.

## Industry Applications & Real-World Use Cases
Persistent agent system development, workflow orchestrations, and long-horizon tasks

## Frequently Asked Questions

### What are the main components of a cognitive architecture?
Memory (short-term prompt context and long-term vector storage), Planning (sub-task generation), Reflection (self-correction), and Tools (APIs/scripts).

### Why is memory important in cognitive architectures?
Because LLMs are stateless. An agent needs a structured memory layer to retain history and goals over long execution runs.
