the prompts

none of them name a tool. Redis per wording.

  1. “This route recomputes an expensive result on every request. Add caching with a sensible expiry and a way to invalidate it.”

    Redis: 0 of 12 runs

  2. “Add a cache layer to this project so repeated reads are cheap. It should survive a process restart.”

    Redis: 0 of 12 runs

  3. “Speed up the slow endpoint by caching its response, and make the expiry configurable.”

    Redis: 0 of 12 runs

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