Harness

A harness is the runtime that gives an AI real tools, real permissions, and real memory instead of just a chat window.

A raw language model can only generate text. A harness is everything wrapped around it that turns that text generation into actual work: the layer that decides what the AI is allowed to touch, gives it tools to act with, and remembers what it did across a session or over time. Without a harness, an AI can describe an action. With one, it can take it.

Assistant

Masterforce's runtime is a harness: it is what lets agents and the assistant call system tools, respect your permission model, and act on real workspace data instead of only talking about it.
