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.

Backslashes in filenames are left alone on macOS and Linux

You'll notice
Useful3 Signal1
File Paths

On macOS and Linux, filenames containing a backslash are no longer rewritten into slashes.

What

A path helper rewrote every backslash to a forward slash on every platform. It now does that only on Windows, so files whose names legitimately contain a backslash are no longer mangled.

Evidence

zt() === "windows"

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