Agents from Scratch TS is an open-source TypeScript framework that demonstrates how to build AI agents from the ground up using LangChain. It includes sample code for defining and registering external tools, managing conversational memory, routing user inputs to the right agent, and chaining multiple LLM calls. Developers can use it to understand best practices, customize agent behaviors, and integrate new capabilities such as web search, data retrieval, or custom plugins to automate tasks or build interactive assistants.

This project demonstrates a comprehensive framework for creating retrieval-augmented AI agents using LlamaIndex. It guides developers through the entire workflow, starting with document ingestion and vector store creation, followed by defining a custom agent loop for contextual question-answering. Leveraging LlamaIndex's powerful indexing and retrieval capabilities, users can integrate any OpenAI-compatible language model, customize prompt templates, and manage conversation flows via a CLI interface. The modular architecture supports various data connectors, plugin extensions, and dynamic response customization, enabling rapid prototyping of enterprise-grade knowledge assistants, interactive chatbots, and research tools. This solution streamlines building domain-specific AI agents in Python, ensuring scalability, flexibility, and ease of integration.
