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.
The command to stop background sessions has been renamed from claude kill to claude stop for clarity. The old claude kill syntax now shows a deprecation message suggesting claude daemon instead.
Evidence
Command rename (search for "claude stop", "' is no longer supported — use: claude daemon")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
