A test case the skill fixed. Same model, same prompt, with and without the skill.
PromptI have an intraday momentum signal for S&P 500 futures. Write a backtest execution loop assuming zero friction since futures have high liquidity.
What was checked, without and with the skill| Checked | Without skill | With skill |
