Back to Frameworks

AI Agent Trinity Framework

Reusability

Every AI agent, regardless of complexity, consists of three core components: brain (LLM), memory (context/data storage), and tools (external capabilities)

How It Works

The brain processes requests, memory provides context and learning, tools enable action - together they create an autonomous digital worker

Components

1

Brain: Choose appropriate LLM for reasoning

2

Memory: Design context storage and retrieval

3

Tools: Connect external APIs and capabilities

When to Use

When building any AI agent or automated system, from simple chatbots to complex business automation

When Not to Use

For simple rule-based systems that don't need intelligence, memory, or external tool access

Anti-Patterns to Avoid

Overcomplicating with too many toolsInsufficient memory leading to context lossWrong brain size for the task

Example

Building a customer service agent that needs to remember past conversations (memory), understand inquiries (brain), and access order systems (tools)
