What probably matters to youSection of the release
Unclear The maximum value is not stated.
What
Before running a PowerShell command, Claude Code reads (parses) it to check what it does. The environment variable CLAUDE_CODE_PWSH_PARSE_TIMEOUT_MS sets how long, in milliseconds, that reading may take. Any positive value used to be taken as given. A value above a built-in maximum is now reduced to that maximum.
Why
If you set a very large timeout, Claude Code now quietly uses a smaller one.
