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 Bash Command Safety Analysis

The Bash command safety checker now correctly parses command wrappers that prepend the real command, preventing false safety denials when using common Unix utilities:

  • timeout — parses --foreground, --kill-after, --preserve-status, --signal, and duration arguments
  • stdbuf — parses -i, -o, -e buffer-mode flags
  • env — parses environment variable assignments and -i, -0, -u, -v flags
  • time, nohup, nice — unwrapped to find the actual command being run
  • These wrappers are recursively stripped before analyzing the inner command for safety
Evidence

Command wrapper parsing (search for "--foreground", "--kill-after", "--preserve-status", "stdbuf")

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