I personally like the way Scion breaks it down into

- model

- harness (tools/config)

- agent (live/running)

https://googlecloudplatform.github.io/scion/concepts/

Scion allows for multiple configurations of a harness, allowing you to configure the same tool differently based on what you are doing, particularly important when you want to restrict permissions.

for the unfamiliar, Scion is an OpenClaw like platform from a Google dev, not supported or sponsored by the company
