Agent UX: developer tools must now serve humans and their agents with one shared surface, argues Ines Montani

- Explosion AI co-founder Ines Montani publishes a post arguing that building developer tools has fundamentally changed: your users are humans and their agents, so a visual app, good API and docs are no longer enough.
- Core thesis: human-agent collaboration needs a shared surface — what you can do in the app, via the API, and what the agent can do should all be the same things, called the same way.
- She borrows Cory Doctorow's framing to contrast centaur systems (human in charge) with the "reverse centaur" — the vibe-only coder reduced to clicking buttons for the machine.
- The post details her team's concrete ideas and solutions for agent UX.
