Agent harness
OpenClaw
OpenClaw · Open-source agent harness
Use this when you want an agent runtime you can shape with local skills, plugins, and workspace-level behavior.
Start
Start with the docs, install the minimum useful setup, then add one skill only after you understand its file access and commands.
Self-improving agent
Hermes Agent
Nous Research · Open-source agent
Use this when persistent memory, skill creation from completed tasks, and remote agent operation matter more than a simple chat UI.
Start
Read the README, run it in a contained environment, and test one recurring workflow before trusting broader memory.
