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.
Skill usage report declines cleanly on unsupported connections

Skills
Skill usage reports now say plainly when your connection doesn't support them.
What's wrong with this entry?
Anonymous. No account, no email.
What
The skill doctor command now checks the session both before and after building the report and returns "Skill usage reports are not available on this connection." rather than partial output. Errors on those connections return a short message with no diagnostic detail.
Evidence
Skill usage reports are not available on this connection.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
