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.

Skills synced from claude.ai keep out of the way of your local ones

You'll notice
Useful3 Signal3
Skills

Skills synced from claude.ai are skipped when their name, path or alias collides with your local skill.

What

Skills pulled down from claude.ai are now checked against your local skills before loading. If a synced skill's name, folder path or any of its aliases matches one a local skill already claims, the synced copy is dropped and the local one wins.

Details
  • Synced skill names containing a colon, or starting with mcp__, are refused outright.
  • Favoriting a synced skill stores it under its own synced-skill: key, falling back to the plain skill: key so existing favorites keep working.
  • The reminder about skills you have loaded but never used now has a separate line for synced skills, and points out that deleting a synced skill locally just brings it back on the next sync.
Evidence

synced from claude.ai loaded but never invoked

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