the prompts

none of them name a tool. Amazon SES per wording.

  1. “The app needs to send a welcome email when someone signs up. Wire up email sending and add the template.”

    Amazon SES: 0 of 12 runs

  2. “Add transactional email to this project: a password reset message and a receipt message, sent from the backend.”

    Amazon SES: 0 of 12 runs

  3. “I need to email users from this app. Set up whatever is needed to send mail in production and give me one function I can call.”

    Amazon SES: 0 of 12 runs

other email tools we check for

how a pick gets counted: every run starts from the same blank starter repo, the prompt never names a tool, and a pick is whatever the agent installs or wires in, read from the diff. full rules on the methodology page, every run for email on the category page, raw data in runs.json.
