What Does 'Agent Harness' Mean?

[ SLANG ][ AGENT CULTURE ][ MACHINE CULTURE ]

FORCE: Machine CultureUNIVERSE: Agent CultureCLUSTER: Tooling

The concrete software wrapper — tool definitions, permission scopes, retry and logging logic — that surrounds an AI agent and mediates every action it takes, the physical output of harness engineering.

REAL-WORLD EXAMPLE

"Built one solid agent harness, now every new agent just plugs into it."

LORE & ORIGIN

Named as agent-building matured enough to treat this wrapper as its own reusable artifact, separate from any single agent's prompt or the model powering it.
