sandbox — An isolated environment where AI-generated code or agent actions run without being able to touch anything real.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
Why it matters
Notion now hosts your code (Workers) and admits externally built agents as native workspace participants via an API, with a CLI for deploys — so agents on other frameworks can act in a workspace without you running infrastructure or bolting on a third-party automation layer.
