A "harness" is basically what you call Claude Code and such, i.e. a TUI to run the agent.

Aren't VS Code, Claude Code, Hermes Agent, Goose or Letta harnesses, but with UI, too?
I thought the harness was mainly a TAI (tangible AGENT interface). Its a harness for the agent, not a user interface. That is bolted on top of the harness.
