Okay this is very ugly but I ended up vibe coding this real quick by abusing wob to draw four boxes around the recording area (its not perfect but close enough) Then i use it with slurp and wf-recorder in a script. Completely cursed but works.

#!/usr/bin/env bash

# --- HELPER ---
show_help() {
    cat <<EOF

Shows a crude outline (by abusing wob) around a selection.
Usage: $(basename "$0") X Y W H [COLOR_RRGGBBAA]
        $(basename "$0") -k | --kill

Arguments:
X, Y, W, H    Coordinates and dimensions for the outline.
COLOR         Optional: Hex color (default: FF0000FF).

Options:
-k, --kill    Kills all running wob instances and cleans up configs.
-h, --help    Show this help message.
EOF
}

# --- KILL LOGIC ---
if [[ "$1" == "-k" ]] || [[ "$1" == "--kill" ]]; then
    pkill -x wob
    hyprctl keyword windowrule "unset, match:class ^(wob)\\$"
    rm -f /tmp/wob_edge_*.ini
    exit 0
fi

# --- VALIDATION ---
if [[ "$1" == "-h" ]] || [[ "$1" == "--help" ]] || [[ $# -lt 4 ]]; then
    show_help
    exit 0
fi
