fast-agent vs ClaudeR

fast-agent: fast-agent is a CLI-first framework for building and interacting with sophisticated multimodal AI agents and workflows. It offers comprehensive support for various LLM providers, structured outputs, and vision, with unique features like MCP Feature support and live streaming responses to the terminal.; ClaudeR: ClaudeR is an R package that connects RStudio to MCP-configured LLM agents like Claude Code and Codex, enabling interactive coding, multi-agent orchestration, automated manuscript auditing, and data annotation. It provides a suite of MCP tools for direct code execution, plot generation, async execution, file reading, and more. The package includes built-in protocols for academic review (Reviewer Zero), statistical best practices, and multi-agent coordination.
