Board game to digital concept extractor — transforms board game rulebooks (PDFs) into development-ready digital game concepts.
RuleForge extracts mechanics, game loops, balance parameters, and produces GDDs, feature lists, user stories, architecture diagrams, and more. It can also translate the extraction into a complete real-time interactive game design.
RuleForge is built as a collection of Claude Code slash commands (skills) that form an extraction and analysis pipeline. Each skill handles a specific stage and writes structured output to a game-scoped directory.
