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.

The "file changed on disk" note tells Claude to speak up

You'll notice
Useful4 Signal3
File Watching

When a file changes under Claude, it's now told to speak up if the change looks wrong.

What

When a file changes underneath Claude mid-session, the note it receives no longer asserts that you made the change deliberately and already know about it. It now says to work from the current contents, to say something if the change looks wrong rather than quietly undoing it, and otherwise not to comment on it.

Details
  • The note refers to the Read tool by name instead of a hardcoded string, so it stays correct if the tool is renamed.
Evidence

changed on disk since you last read it

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
