Poisson Labs · Tools
Four open-source tools: one built and in use by the lab, three in development.
These are what the lab’s audits and studies run on. Each answers one question and works on its own, on your own machines, with nothing sent home.
-
Prove
Built · pre-release
Did the fix work?
Reruns the same conditions on the same seeds, before and after a change: what got better, what got worse, what was too small to detect.

Break
In development
What breaks it?
Throws tool errors, timeouts and truncated outputs at your agent and hunts for the conditions where it fails.
Open source No page yet
-
Trace
In development
Which step failed?
Reads OpenTelemetry and LiteLLM traces and points at the steps where runs are being lost.

Tasks
In development
Where does it break as one thing gets harder?
Agent tasks that get harder one knob at a time, each with its own verifier, so a failure can be pinned to the thing that changed.

Where they go
Break, Trace, Prove: three of these run in that order, and Sangfroid is the platform that runs them for you on every pull request. Tasks feeds them the tasks to run on.
A tool gets its own page when there is something on it a reader can check. Break and Trace are waiting on public repositories. The methods they share are written down now.
