Claude Code v2.1.69 ·

Improved Command Shell Safety Checks

Entry
JSON All of v2.1.69
EntryKind: in v2.1.69,
ChangesSection of the release

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.
