> Fixing unreliable agents by adding more unreliable agents.

I think the 'reliability add' is from how it's presented back to the user. If you can trust the agent to at least say what tool it called, then you can mark a chart as being the canonical output of "get_projected_profit" tool vs "get_realised_profit" tool and everyone knows it hasn't come down to the current dice roll of randomness what the agent itself did this time.
