Blue Agent serves as a comprehensive toolkit for constructing AI-driven agents in Node.js. It enables developers to implement chain-of-thought prompting to improve reasoning, integrate external tools and APIs for enriched functionality, and maintain conversation memory for context retention. The framework features a planning engine that sequences tasks, an execution module to perform actions, and built-in logging to track agent decisions. Developers can define custom tool interfaces, orchestrate multi-step workflows, and leverage function calling to interact with services. Blue Agent's modular architecture allows seamless extension with plugins and supports debugging tools for observing agent behaviors, making it ideal for building advanced chatbots, autonomous assistants, and automated pipelines.

llm-ReAct implements the ReAct (Reasoning and Acting) architecture for large language models, enabling seamless integration of chain-of-thought reasoning with external tool execution and memory storage. Developers can configure a toolkit of custom tools—such as web search, database queries, file operations, and calculators—and instruct the agent to plan multi-step tasks, invoking tools as needed to retrieve or process information. The built-in memory module preserves conversational state and past actions, supporting more context-aware agent behaviors. With modular Python code and support for OpenAI APIs, llm-ReAct simplifies experimentation and deployment of intelligent agents that can adaptively solve problems, automate workflows, and provide context-rich responses.
