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.

Path normalization rewrites each path segment

Under the hood
Useful1 Signal3
Directory Sync

Path handling now transforms each segment, with new six-character reserved-name lists.

What

The helper that converts backslashes to forward slashes now also splits the path and maps every segment through a transform, falling back to the segment unchanged. New sets that cut reserved and ignored names to six characters suggest filename sanitisation for sync, but the transform itself is not identifiable in this build.

Evidence

replaceAll("\\", "/")

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