How to Build a Coding Agent with Nico (Amp Code)

“It’s an LLM, a loop, and enough tokens.” —Nicolay Gerold, Amp Code So why does a coding agent forget your instructions, keep reading tiny pieces of a file, or struggle with an edit another model handles easily? Nicolay Gerold (Amp) joins Hugo to take that loop apart and explain the harness around it: the software that executes tools, manages context, and lets you steer the agent’s work. Nico builds this machinery for Amp, a coding agent that works across software projects. “Every component in a harness is basically an assumption the model can’t do it on its own. This expires over time.” — Nic
