Source Intelligence

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.

Improved Newline Security Check

The bash command newline injection check has been updated with a more comprehensive regex pattern that better handles line continuations (backslash-newline sequences) as legitimate, while still catching suspicious newline patterns.

Evidence

Updated newline detection regex (search for "NEWLINES" in the security check)

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