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.

PowerShell parsing tables added

Under the hood
Useful2 Signal3
Windows

Tables for parsing PowerShell commands landed, groundwork for judging Windows command safety.

What

Constants for taking PowerShell commands apart land in the build: the common parameters -erroraction, -warningaction, -informationaction, -progressaction with aliases -ea, -wa, -infa, -proga; variable-capturing parameters such as -errorvariable, -outvariable, -pipelinevariable; scope names, action values including the numeric forms, an approved-verb list, a Unicode whitespace splitter and a smart-quote pattern.

Details
  • Consistent with tighter safety analysis of PowerShell commands; the code consuming these tables is elsewhere in the bundle.
Evidence

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