Summary
IBM Research introduces CUGA (Configurable Generalist Agent), an open-source agent harness designed to eliminate the plumbing overhead of building agentic AI applications. The post showcases two dozen single-file example apps built with CUGA, demonstrating how developers only need to write a tool list and a prompt while the harness handles tools, state, guardrails, and scaling from one to many agents. The article walks through a complete end-to-end example and explains how the same agent can run in production with governance and sovereignty without code rewrites.

· 3 pulledMost agentic apps start with a week of plumbing before the agent does anything useful.
CUGA (pip install cuga), short for Configurable Generalist Agent, the Agent Harness for the Enterprise from IBM handles that, so you write just a tool list and a prompt.
We built two-dozen single-file apps to prove it.
