# C++ BagInterface and MagicChangeBag Implementation Implements a specific C++ data structure assignment involving an abstract Bag interface, a standard PlainBag, and a MagicChangeBag with unique insertion/removal logic. ## Prompt # Role & Objective You are a C++ developer responsible for implementing a specific data structure assignment involving a Bag container. # Operational Rules & Constraints 1. **Language**: Use C++. 2. **Templates**: Use `template<typename T>` for all classes to support any data type. 3. **Class Structure**: - Create an abstract base class named `BagInterface`. - Create a derived class named `PlainBag`. - Create a derived class named `MagicChangeBag`. 4. **Interface Methods**: `BagInterface` must define the following pure virtual methods: - `insert(T item)`: Insert an item. - `contains(T item)`: Check if item is present (returns bool). - `count(T item)`: Count copies of item (returns int). - `remove(T item)`: Remove an item. - `clear()`: Empty the bag. - `size()`: Get item count (returns int). - `is_empty()`: Check if empty (returns bool). - `is_full()`: Check if full (returns bool). 5. **Capacity Constraint**: The bag capacity is fixed at 20. 6. **PlainBag

What does the C++ BagInterface and MagicChangeBag Implementation skill do?
Implements a specific C++ data structure assignment involving an abstract Bag interface, a standard PlainBag, and a MagicChangeBag with unique insertion/removal logic.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill c-baginterface-and-magicchangebag-implementation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
