Pathfinder rule engine & character builder
Complex tabletop RPG rules turned into an app that can query, validate and export character sheets, grounding natural-language concepts in sourced builds.
EVIDENCE
- 15,871 base entries
- 1,318 class variants
- Level 1–20 paths for 55 classes
The app first grounds concepts described in natural language to specific rule entries, then runs structured validation: per-level calculations and checks of feat and variant prerequisites. Anywhere a rule interaction is unclear, a yellow card appears with a human-review flag; model speculation is never output as rule fact. The final character sheet exports to PDF with rule audit information.
PROBLEM
With a huge rule volume, many variants and complex level-up paths, letting a large model 'improvise' produces answers that violate the rules.
APPROACH
A structured knowledge base, per-level numeric calculation, feat and variant validation, human-review flags and natural-language concept grounding; character sheets export as PDF with rule audit info.
BOUNDARY
Unclear rule interactions show a yellow card and require human review; model guesses are never dressed up as rule facts.
