What
An anchored artifact comment now records a label for its location, the nearest heading or a name the page gives that spot, alongside the existing file and path information.
Details
- The label is captured when the thread is created.
- It is shown to Claude both in the tool output listing live threads and in the prompt used to react to comments automatically.
Evidence
says where on the page this thread sits (the nearest heading, or a name the page gives that spot)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
