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.
A skill available from two sources now shows up once at startup, not twice.

What
The startup payload listing agents, skills and plugins now removes duplicate skill names before filtering, so a skill available from two overlapping sources appears once instead of twice.
Evidence
skills: wA(e.skills, "name")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
