What is an agent harness?

An agent harness is the surrounding setup that lets an AI model act on a task. It can include instructions, skills, tools, environment mappings, checks and workflows. Harness Library focuses on reusable, task-specific setups: from a small skill folder to an MCP workflow or a larger harness package.
