Patrick Collison posted that he likes agentic coding harnesses but they should not stay primarily terminal-based. The terminal gives low information density and few UI options, he said, though TUIs can work for quick tasks. Romain Huet from OpenAI replied that the Codex app supplies computer use, in-browser annotations, and a richer surface for agents. Other replies pointed to ChatGPT Work for parallel agents, files, and previews in one workspace, Conductor as a GUI that manages multiple harnesses and supports cloud workspaces, and web apps such as deepseek-harness and t3code that users can fork and modify.
