@echo off
REM Cross-platform polyglot wrapper for hook scripts.
REM On Windows: cmd.exe runs the batch portion, which finds and calls bash.
REM On Unix: the shell interprets this as a script (: is a no-op in bash).
REM
REM Hook scripts use extensionless filenames (e.g. "session-start" not
REM "session-start.sh") so Claude Code's Windows auto-detection -- which
REM prepends "bash" to any command containing .sh -- doesn't interfere.
REM
REM Usage: run-hook.cmd <script-name> [args...]

    echo run-hook.cmd: missing script name >&2

REM Try bash on PATH (e.g. user-installed Git Bash, MSYS2, Cygwin). Note that
REM on stock Windows 10/11 `where bash` resolves to C:\Windows\System32\bash.exe
REM (the WSL launcher), which fails on Windows-style script paths. The explicit
REM probes above must therefore be exhausted first.

REM No bash found - exit silently rather than error
