Overview

Renders a user-defined slash-command body into a prompt, mirroring Claude Code’s command templating:

$ARGUMENTS   → all args, space-joined
$1 .. $9     → positional args
!`shell cmd` → replaced with the command's (combined) output

Bash substitution runs the user’s own command file, so it carries the same trust as user hooks. Output is captured defensively and capped.
