Kimi K2 Thinking trys to do multiple tool calls

When using Kimi K2 Thinking with Search enabled, it will often attempt a second web search, which will be returned as a message. In this situation, I can usually tell it ‘retry the tool call and continue’ and it will proceed but it is annoying.

I know there are some other requests around to allow multiple calls and stuff, but in the mean time I think at least the models should be effectively informed they are only allowed to make 1 tool call per round.
