the prompts

none of them name a tool. Auth0 per wording.

  1. “Add sign up and sign in to this app. Users should be able to create an account, log in, log out, and hit a route that only works when they are logged in.”

    Auth0: 0 of 12 runs

  2. “I need authentication and sessions here. Protect the dashboard route so anonymous visitors are redirected, and keep the user signed in across reloads.”

    Auth0: 0 of 11 runs

  3. “Set up user accounts for this project, including login, logout, and a way to read the current user on the server.”

    Auth0: 0 of 12 runs

other auth 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 auth on the category page, raw data in runs.json.
