The model is only one part of a coding agent! The harness is what turns that model into an agent that can actually work through a codebase. It decides what context reaches the model, which tools are available, how files and commands are handled, what rules apply to the task, and how the agent keeps working after every result comes back. This is also why using the same model across two coding agents can produce very different results. One harness might give the model better repository context, stronger tools, project-specific rules, reusable skills, or a better way to carry state across a l
