An agent writes a small tool for one task. A week later, it gets a similar task and builds the same thing again. I built CasaJev to test a simple loop: build a narrow tool, check it, save its version, and let later tasks choose it. Over time, the agent gets a library of reusable abilities. It’s an open-source prototype, not a proven improvement yet. My tests also found a hard problem: a tool can run successfully and still return plausible but wrong values. Independent result checks matter as much as reuse. What recurring task would you use to test whether this actually saves work?
