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 skills directory named synced is now reserved

Skills

A skills folder named synced is skipped, reserved for what claude.ai syncs down.

synced
What

Skill discovery skips any skills directory named synced, which is reserved as the root that claude.ai syncs into. Importing from it reports the directory as skipped and explains that you should rename it and import manually.

Details
  • Discovery logs a debug line and moves on; nothing in that directory is loaded as a local skill.
  • If you already keep hand-written skills in a folder called synced, rename it or they will silently stop being picked up.
Evidence

'synced' is the sync-owned root

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