Practical AI Agents provides developers with a comprehensive framework and ready-to-use examples to construct autonomous agents powered by large language models. It demonstrates how to integrate API tools (e.g., web browsers, databases, custom functions), implement RAG-style memory, manage conversation context, and perform dynamic planning. You can adapt examples for chatbots, data analysis assistants, task automation scripts, or research tools. The repository includes notebooks, Dockerfiles, and configuration files to streamline setup and deployment across environments.

Spellcaster provides a structured approach to building AI Agents by using 'spells'—a combination of prompts, logic, and workflows. Developers write YAML configurations to define agents’ roles, inputs, outputs, and orchestration steps. The CLI tool executes spells, routes messages, and integrates seamlessly with OpenAI, Anthropic, and other LLM APIs. Spellcaster tracks execution logs, retains conversation context, and supports custom plugins for pre- and post-processing. Its debugging interface visualizes the sequence of calls and data flows, making it easier to identify prompt failures and performance issues. By abstracting complex orchestration patterns and standardizing prompt templates, Spellcaster reduces development overhead and ensures consistent agent behavior across environments.

Whiz is designed to provide a robust foundation for developing intelligent agents that can perform complex conversational and task-oriented workflows. Using Whiz, developers define "tools"—Python functions or external APIs—that the agent can invoke when processing user queries. A built-in memory module captures and retrieves conversation context, enabling coherent multi-turn interactions. A dynamic planning engine decomposes goals into actionable steps, while a flexible interface allows injecting custom policies, tool registries, and memory backends. Whiz supports embedding-based semantic search to fetch relevant documents, logging for auditability, and asynchronous execution for scaling. Fully open-source, Whiz can be deployed anywhere Python runs, enabling rapid prototyping of customer support bots, data analysis assistants, or specialized domain agents with minimal boilerplate.
