Better question yet, how do you have agents contribute openly without an insane risk of leaking keys, credentials, PII, etc, etc?

Again it's a terrible idea, and yet I'll SMASH that like button and use it anyway

I trust that an LLM can fix a problem without the help of other agents that are barely different from it. What it lacks is the context to identify which problems are systemic and the means to fix systemic problems. For that you need aggregate data processing.
