Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Comment threads say where on the page they sit

Under the hood
Useful2 Signal3
Artifacts

Anchored artifact comments now record the nearest heading, so their location is described.

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.
