A fun one is that in claude code, you can configure 'agents' which are prompt presets + some configuration. Or sub-agents sometime are indistinguishable from the foreground agent (usually called orchestrator) in configuration except that they have different contents in their context window (forks more or less).

IMO, if there's a ubiquitous term that is unambiguous, use it (harness, model). If there's an ambiguous term you have to explain, try not to use it. Language is for communication.
