theodosia vs hermes-agent

theodosia: Theodosia acts as a gatekeeper for Burr applications, mounting them as a FastMCP server to manage tool calls and ensure state machine transitions are valid. It significantly improves agent reliability and traceability by enforcing graph logic and logging all interactions, including structured refusals.; 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.
