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.

Synced skills can no longer take a slash-command name that sometimes exists

Slash Commands

Synced skills can no longer take over slash-command names that only exist in some states.

What

Slash commands that only appear in certain states (fleet fork, fleet background, daemon, skill doctor, logout) now reserve their names permanently. A skill synced from your account that collides with one of those names, or with a local or plugin command, is dropped and logged instead of shadowing it.

Details
  • Each conditional command set now declares both the names it uses when open and the names it uses when closed, and every name from both lists is reserved.
  • If local or plugin skills fail to load at all, every synced skill is dropped, because there is no way to check its name for collisions.
Evidence

a non-synced command or an earlier synced skill owns that name

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