What
The whole set of bundled claude-api skill guides shows up as new text in this build, but this is a bundling artifact. The file map has the same 65 entries, every document occupies the same line span with the same content, and no model ID, beta header or guide entry changed. The skill works exactly as before.

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