PHP Code:

stock TF2_AddCond(client, cond) {
    new Handle:cvar = FindConVar("sv_cheats"), bool:enabled = GetConVarBool(cvar), flags = GetConVarFlags(cvar);
    if(!enabled) {
        SetConVarFlags(cvar, flags^FCVAR_NOTIFY);
        SetConVarBool(cvar, true);
    }
    FakeClientCommand(client, "addcond %i", cond);
    if(!enabled) {
        SetConVarBool(cvar, false);
        SetConVarFlags(cvar, flags);
    }
}
stock TF2_RemoveCond(client, cond) {
    new Handle:cvar = FindConVar("sv_cheats"), bool:enabled = GetConVarBool(cvar), flags = GetConVarFlags(cvar);
    if(!enabled) {
        SetConVarFlags(cvar, flags^FCVAR_NOTIFY);
        SetConVarBool(cvar, true);
    }
    FakeClientCommand(client, "removecond %i", cond);
    if(!enabled) {
        SetConVarBool(cvar, false);
        SetConVarFlags(cvar, flags);
    }
} 


TF2_AddCond(client, 5) will ubercharge a player and TF2_AddCond(client, 11) will kritzkrieg them (works with tf_weapon_criticals 0).
