hermes-agent vs cli

hermes-agent: Hermes Agent is a self-improving AI agent from Nous Research with a built-in learning loop: it creates skills after complex tasks, improves them during use, searches its own past sessions and builds a model of the user over time. It works with any model provider, talks through a terminal UI or Telegram, Discord, Slack, WhatsApp and Signal, and runs on local, Docker, SSH or serverless backends.; cli: Syrin is a CLI tool designed to lint and test MCP (Model Context Protocol) servers, ensuring AI agents call external tools correctly. It identifies common issues like vague descriptions, underspecified inputs, and problematic tool behaviors before they reach production, preventing agent malfunctions and wasted tokens.
