About this skill

The computed interactive-fiction / gamebook engine core for Godot 4 (spec phases P0 + P1) — a pure, seedable, headless-tested engine that plays a data-driven narrative graph (passages/choices/conditions/effects) over a GENERIC rule engine where a ruleset is DATA, not code. Use when a template needs deterministic text-RPG / gamebook resolution with NO LLM and NO networking: attribute/dice checks, item gates, variable & flag effects, branching to endings — with (P1) reusable MODULES, one-off AND campaign adventures, save/load with separated short-term (session) + long-term (campaign/world/character) stores, and DUAL-TIER characters (a lightweight persistent sheet OR a consume-only binding to a full companionaicore entity); and (P2) THREE full genericised ruleset builtins as data (ff-2d6, srd-d20, pbta), a ruleset VALIDATOR/IMPORTER (the engine half the future Ruleset Builder UI writes to), and ruleset-PORTABILITY — a canonical check abstraction (a semantic + a canonical attribute + a canonical difficulty + canonical outcome bands) that lets ONE scenario run under EVERY system. Extends ff-gamebook SessionState + the VN runtime-variables/inventory model + the companion- interchange projection. Full design: Noxdev-Studio/docs/GAMEBOOKENGINESPEC2026-07.md (§2, §2.5, P0+P1+P2).
