AX

Also called: agent experience, A X, agent UX

Agent experience: how well a project is set up for an AI agent to do good work, with a clear structure, automated checks that catch mistakes and instructions that do not waste its context. It is to agents what developer experience is to people, and it matters most when nobody is watching.

For example: A team adds tests that run in seconds and a short AGENTS.md, and its agents start finishing tasks without getting stuck.
