+# Sub-Task 5: CraftingTab Design Phase Compatibility (Bug 7)
+
+## Scope
+- **Components affected**:
+  - `components/CraftingTab.tsx` (Design phase section)
+  - Enchantment data sources (e.g., `data/enchantments.ts`)
+  - Player inventory state (to check owned items)
+- **Files potentially affected**:
+  - `utils/craftingUtils.ts` (enchantment compatibility logic)
+  - `types/crafting.ts` (enchantment-item compatibility types)
+  - `store/inventorySlice.ts` or similar for player item data
+
+## Acceptance Criteria
+1. In CraftingTab Design phase, only enchantments compatible with items the player currently owns are shown (verify by checking UI with different inventory states)
+2. Compatibility is determined by enchantment type (e.g., weapon enchantments only show if player owns weapons)
+3. No performance issues when filtering enchantments
+
+## Dependencies
+- None (independent, but Sub-Task 6 depends on this if modifying same CraftingTab file)
+
+## Estimated Complexity
+- Medium (data filtering + UI update)
