Tool Library
Working tools, free to run.
Each tool red-teams a real mechanism — an incentive rule, a payout split, a game's time structure — entirely in your browser. Nothing is fetched, nothing is stored, and the source shown is the source that runs.
Every tool ships first with an issue of Bernard's Solved Game, then graduates here free 30 days later, hardened.
The Gaming Surface Scanner
Point it at an agent payout or settlement rule. It prices three gaming surfaces — valuation misreport, success misreport, and sybil pooling — and tells you whether honest reporting is a dominant strategy or exploitable, and by what percent. Flip on the toll fix and watch every attack go underwater.
The Horizon-Collapse Linter
Point it at a game's time structure — seasons, vesting cliffs, auction windows, agent task-loops with a visible stop. It finds the round where the shadow of the future gets too short for the Folk Theorem to hold, and cooperation unravels by backward induction. Toggle rolling horizons and the collapse disappears.
