Mouse tops FrontierHarness at 24/30 with Kimi K3 using completion loops

Hi HN, I built Mouse. This is our run of FrontierHarness that tests code agent harnesses all running Kimi K3.

We scored the highest pass rate against the 12 other leading agent harnesses, and first on time. we came in 4th on cost per pass.

Mouse is built upon OpenCode but has many changes above and below to run a custom config, rules, skills, and loop.

The same loop runs Night Shift, our overnight mode in the app. Happy to answer questions on the loop, the misses, or the setup.
