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.

Enhanced Shell Safety Checks

New safety checks for shell commands:

  • Detection of carriage returns (\r) in commands, which shell-quote and bash tokenize differently — a potential injection vector
  • Detection of unquoted redirect operators in git commit remainder arguments
  • Improved metacharacter detection for glob, backtick, dollar-sign, and other shell expansion characters in tool inputs
Evidence

Carriage return detection (search for "Command contains carriage return")

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