Problem Description

Filter inlet functions only run on initial requests, not when tool results are sent back to the model. This breaks parameter persistence.

Example Filter:

def inlet(self, body, __user__):
    body["reasoning"] = {"effort": "medium"}
    return body

Impact (using models via OpenRouter with native function calling):

Claude Sonnet (defaults no reasoning): Reasons initially with Filter, stops after tool call
GLM-4.6 (defaults to reasoning): Doesn't reason initially without Filter, starts reasoning after tool call

Filter modifications don't persist through tool interactions.

Desired Solution you'd like

Invoke Filter inlet on tool continuation requests, same as initial requests.

Alternatives Considered
