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.

Angle brackets rejected in display names and paths

Internals

Angle brackets are now rejected in display names and paths alongside other unsafe characters.

What

The filter that rejects unsafe characters in labels now also rejects < and > and their fullwidth equivalents, on top of the control characters, brackets, quotes and backslashes it already caught. A separate URL matcher was tightened to stop absorbing angle brackets and the ellipsis character.

Evidence

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