Definition
An agent action surface is the part of a page that exposes what can be done next, how it is done, and under what constraints.
Without that surface, an assistant has to guess whether the page supports comparison, contact, download, or purchase.
In Practice
Service pages with scope, deliverables, timeline, and next-step instructions create a stronger action surface than pages built only around persuasion.
FAQ and glossary support layers reduce the amount of guessing needed.
Worth Knowing
This concept becomes more important as assistants move from summarizing to acting.
A clear action surface benefits human readers too.
