What
Artifacts are web pages that Claude writes for you. Claude's instructions for writing them list device features that the page frame refuses, and motion sensors are now on that list. Before, the instructions simply said not to build features on those devices.
Now Claude may build on one of them only when you have a runtime capability for that device, meaning your setup actually supports it, and the page declares that it uses it. The instructions name a skill to use for this. The sentence about keeping the screen awake is now separate.
Why
This changes the artifacts Claude writes. Pages can now use some device features where they will work, instead of avoiding them entirely.
