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 Command Shell Safety Checks

New obfuscation detection for potentially dangerous shell commands:

  • Quoted newlines followed by #-prefixed lines that could hide arguments
  • Consecutive quote characters at word start (potential obfuscation)
  • Empty quote pairs adjacent to quoted dashes (flag obfuscation)
  • Quoted brace characters inside brace contexts (brace expansion obfuscation)
  • Excess closing braces after quote stripping
Evidence

Safety checks (search for "Command contains a quoted newline followed by a #-prefixed line")

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