How to block /<tab>?

[blackid512]

I want to block /tab, but my server is using 1.8, so MundoSK isn't compatible with the server.
When I change my server to 1.8, Some addons can't used too.

options:
    blocked-commands: "/bukkit", "/version" and "/plugins"

on packet:
    if event-string is "PacketPlayInTabComplete":
        if "%packet field ""a""%" is {@blocked-commands}:
            cancel event

The syntax I found from @ShaneBee
I dont know what is the packet field & how to use that syntax.
