game-balance-audit is a free, MIT-licensed agent skill from Chugli Games, a small studio that makes browser story games about Indian family life. It was first published on GitHub on October 27, 2026, and was at version 0.3.0 as of November 2026.
You point an agent at a game's code, a spreadsheet, a rulebook or a running web build. According to the README, the agent first works out what the game is meant to achieve (ad or purchase revenue for free-to-play, completion for premium, fairness for tabletop), computes exact odds where it can, and builds a small simulator for the rest. Bots ranging from careless to expert play hundreds of seeded runs, and each simulated number comes with a 95% interval. The output is a balance-audit/ folder with a report that ranks problems and gives three suggestions for each, every one tested in the simulator.
It targets merge-2, match-3, puzzle, board and card games, plus slots, loot tables and gacha. The README says a typical audit takes 30 to 90 minutes of agent time, needs Node 18+ or Python 3.7+ and makes no network calls. It installs as a Claude Code plugin or, through the skills CLI, into other agents that read the Agent Skills format.
The authors publish their own with-and-without comparison noting that plain Claude also found the bugs planted in its small test examples; the skill adds goals, tested alternatives and checkable numbers at 2 to 4 times the cost. AIGamer has not tested it.
Limitation: The README says it handles real-time, physics-driven and deep strategy games poorly, and that its bots don't behave like real players, so absolute numbers need checking against analytics or playtests
