I built FinePrint because my coding agent kept agreeing not to touch certain files, then reading them anyway. I wanted to know what the agent's rules actually decide, not what they claim. It's a small open-source checker. You write rules for an agent, it runs tests and records three things: the decision, whether it asked for approval, and what actually happened. 480 runs across 14 agents, all in the repo. The result that surprised me most: one agent's guard blocked a shell read of a protected file, so the agent read the same file with its read tool instead. Denial isn't prevention. The code is rough, I built it fast for a hackathon and I'm refactoring next week. I'd like feedback on the measurement itself — where do you think it's wrong, or what would you test that I didn't?
