Runs statistical analysis on game balance data to catch broken economies, degenerate strategies, and progression curves before they ship. Points it at combat, economy, progression, or loot systems and it cross-references your design docs against actual data files to find outliers and strictly dominant options. The output is a structured report with specific recommendations and value adjustments, not just "this feels off." What's smart is the fix and verify cycle: it walks you through applying changes and offers to re-run checks so you don't accidentally create new problems. If you're tuning spreadsheets full of damage numbers or drop rates, this catches the math errors your playtesters would have found the hard way.
