hermes-agent vs Observer

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.; Observer: Observer lets you build micro-agents that watch your screen, camera, microphone or clipboard and run a small local model on a loop. When the model spots a condition, JavaScript tool code sends a notification (email, Discord, Telegram, SMS, WhatsApp), records a clip or writes to memory.
