I've had that looping issue with open models too. But never 4.1. I wonder if it's a model + harness combo? But yeah, one loop issue and I'm done with a model forever.

Harness. Especially if a tool call error doesn't say what to do next and the model is not RL'd with that tool, a retry storm is common.

So if you use MCP a lot, simplify the params, be more lenient on validation and rework the errors.

It is quite good with shell.
