would this not be trivially solved by say - removing the websearch skill from the main orchestrating agent and have it always delegate to some subagent? a subagent sans knowledge of any pii would categorically be unable to exfiltrate any information. granted, populating the subagent with useful context stripped of any pii might require a bit of work and not be perfect, i feel like it would take us 90% of the way there. am i missing something?
