## What it does

The skill lays out how inventories work in Diablo, Resident Evil and Minecraft, then maps those patterns onto Godot. A scenario table routes you to the right script: slot bags with stacks, a Tetris grid with item footprints, equipment, loot tables, consumables, persistence and item database loading. Each row names its file — `inventory_data_resource.gd`, `grid_inventory_logic.gd`, `loot_table_resource.gd`, `inventory_persistence.gd` and others.

Items are `Resource` objects, never nodes. Adding runs in two passes: fill partial stacks first, then empty slots, and only after weight and volume checks. The UI binds once to `inventory_updated` and reuses existing slot widgets instead of rebuilding the whole list. Saving writes just `item_id` or `resource_path` plus the amount.

The skill leans on companion topics such as `godot-resource-data-patterns` and `godot-signal-architecture`, so skipping those leaves some decisions dangling. One rule stands out: duplicate a blueprint resource with `duplicate(true)` for each stack instance, or changing quantity in one slot corrupts every copy of that `.tres`. That bug tends to surface only once the game is running.
