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.

Skill versions can carry a "what changed" note

Useful3 Signal3
Skills

Skill and artifact versions can carry a short "what changed" note shown in the picker.

What

When publishing a versioned skill or artifact, authors can attach a short note describing what is new or reworked in that version. It is shown beside the version label in the version picker.

Details
  • Optional field, publish only, with no feature flag.
Evidence

publish only: what changed in this version — a few sentences on what is new or reworked, shown beside \label\ in the version picker

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