My First Agent: Trading
Why this one: Trading scored highest because it combines meaningful time cost with the single highest-impact outcome — profitability. You identified it yourself as the activity with the biggest real-world financial upside if handled better, which signals strong motivation to build and actually use it. The asymmetric reward profile makes it the obvious first build.
What success looks like: The agent surfaces high-quality trade signals or executes a defined strategy consistently enough that it measurably improves decision quality or P&L over a defined trial period.
(I agree with this assessment)
