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.

bedrock-agent is a versatile AI agent framework that integrates with AWS Bedrock’s suite of large language models to orchestrate complex, task-driven workflows. It offers a plugin architecture for registering custom tools, memory modules for context persistence, and a chain-of-thought mechanism for improved reasoning. Through a simple Python API and command-line interface, it enables developers to define agents that can call external services, process documents, generate code, or interact with users via chat. Agents can be configured to automatically select relevant tools based on user prompts and maintain conversational state across sessions. This framework is open-source, extensible, and optimized for rapid prototyping and deployment of AI-powered assistants on local or AWS cloud environments.
