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 new unquotedKeepQuoteChars field is now returned from command parsing, providing a third representation of commands alongside withDoubleQuotes and fullyUnquoted. This variant preserves quote characters in the output, enabling more accurate security analysis of commands where quote placement matters (e.g., the new mid-word hash check).
Evidence
New parsing field (search for "unquotedKeepQuoteChars")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
