+## Project
+
+**Hytale Gravity Flip**
+
+Plugin serveur Hytale (Java 25) qui introduit des **zones de gravité inversée**. Toute entité (joueur, item, mob) entrant dans une zone définie voit sa gravité inversée : marche au plafond, les items tombent vers le haut.
+
+**Core Value:** **Créer des mécaniques de niveau "gravity-flip" en jeu sans toucher au code** : un builder définit une zone via un wand, nomme la région, et la mécanique s'active immédiatement pour toutes les entités qui y entrent.

+## GSD Workflow Enforcement
+
+Before using Edit, Write, or other file-changing tools, start work through a GSD command so planning artifacts and execution context stay in sync.
+
+Use these entry points:
+- `/gsd-quick` for small fixes, doc updates, and ad-hoc tasks
+- `/gsd-debug` for investigation and bug fixing
+- `/gsd-execute-phase` for planned phase work
+
+Do not make direct repo edits outside a GSD workflow unless the user explicitly asks to bypass it.

+## Developer Profile
+
+> Profile not yet configured. Run `/gsd-profile-user` to generate your developer profile.
+> This section is managed by `generate-claude-profile` -- do not edit manually.
