466466* `"shell": "powershell"` on individual [command hooks](/docs/en/hooks#command-hook-fields): runs that hook in PowerShell. Hooks spawn PowerShell directly, so this works regardless of `CLAUDE_CODE_USE_POWERSHELL_TOOL`.
467467* `shell: powershell` in [skill frontmatter](/docs/en/skills#frontmatter-reference): runs `` !`command` `` blocks in PowerShell. Requires the PowerShell tool to be enabled.

471PowerShell commands also receive the variables hooks persist through `CLAUDE_ENV_FILE`, under the conditions in [Persisted variables in PowerShell commands](/docs/en/hooks#persisted-variables-in-powershell-commands). Requires Claude Code v2.1.296 or later.

471473Exit code 1 from `grep`, `rg`, `egrep`, `fgrep`, `findstr`, and `git grep` means no matches. Exit code 1 from `git diff` means differences exist. Neither result is reported to Claude as a command failure. For `robocopy`, exit codes 0 through 7 are informational results, such as files copied or extra files detected. Exit codes of 8 or higher count as failures.
