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.

What

Plugin skill loading now carries an object-valued metadata frontmatter field through into the loaded skill record.

Details
  • Stored alongside declaredFields rather than being dropped during parse.
  • No user-visible behaviour attaches to the field in this build.

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