Agents are demystified as LLMs with tool-calling capabilities—no orchestration frameworks needed. The release adds an Agent base class with macros for model configuration, instructions, tools, and temperature, supporting lazy evaluation for runtime context. Rails integration enables prompt conventions via ERB templates and persisted chat sessions. The update also includes AWS Bedrock full coverage via Converse API, Azure Foundry API support, and clearer instruction semantics. ## Full article daily.dev links to this article rather than hosting it.
