server_cvar(cvarname, cvarvalue) - very useful to check if player tries to cheese the map by trying to change server cvars and handle it accordingly, see example below.

Instance.OnServerCvar((cvarname, cvarvalue) => {
    const bannedCvars = new Set([
        "sv_airaccelerate",
        "sv_jump_spam_penalty_time",
        "sv_staminajumpcost",
        "sv_staminalandcost",
        "sv_air_max_wishspeed",
        "sv_enablebunnyhopping",
        "sv_accelerate",
        "sv_autobunnyhopping"
    ]);

    if (bannedCvars.has(cvarname)) {
        Instance.ServerCommand("kickid 0");
    }
});

If anyone has more suggestions (or use cases to the ones above), feel free to mention them.

It would be nice if there was a parameter added to OnKnifeAttack for whether it was a primary or secondary attack.
To be able to handle each one differently if desired.
