What is Creational Pattern Selector?
The Creational Pattern Selector is a technical intelligence module designed to solve the common architectural problem of inflexible object creation. By analyzing codebases for hard-coded constructor calls and complex initialization logic, this skill guides developers through the selection of one of the five classic creational patterns: Abstract Factory, Builder, Factory Method, Prototype, or Singleton.
Leveraging Openclaw Skills, this tool provides a structured decision framework that balances two primary strategies: class-based parameterization through subclassing and object-based parameterization through composition. It ensures that developers don't just pick a familiar pattern, but the one that best fits their system's evolution path and runtime requirements.
Creational Pattern Selector Use Cases
- Replacing scattered new ConcreteClass() calls with flexible creation hooks.
- Designing systems that require the creation of families of related or dependent objects.
- Simplifying complex, multi-step object construction processes (e.g., document converters).
- Implementing runtime object creation via cloning to avoid subclass explosion.
- Ensuring global access to a single instance of a resource or state manager.
How Creational Pattern Selector Works
- Frame the Problem: Identify if the issue lies in product type variation, construction complexity, or uniqueness constraints.
- Determine Parameterization Strategy: Choose between subclass-based (Factory Method) or composition-based (Abstract Factory/Builder/Prototype) approaches.
- Apply Checklists: Validate the scenario against specific applicability criteria for each of the five patterns.
- Map Evolution Path: Evaluate if the design should start simple (Factory Method) or requires immediate flexibility (Abstract Factory).
- Generate Recommendation: Produce a scored report including trade-offs, decoupling benefits, and alternative patterns considered.
Creational Pattern Selector Setup
To add this capability to your environment, use the following command through your Openclaw Skills manager:
clawhub install bookforge-creational-pattern-selector
Ensure that the design-pattern-selector dependency is also installed for full routing capabilities.
Creational Pattern Selector Data Schema & Taxonomy
The skill organizes its analysis using a structured taxonomy of creation problems:
| Element | Description |
|---|---|
| Product Type | Single object, family of objects, or complex composite. |
| Variation Axis | Whether the concrete class, construction steps, or state needs to vary. |
| Flexibility Timing | Compile-time vs. Run-time requirements. |
| Strategy | Categorization as Subclassing vs. Composition. |
Creational Pattern Selector Advanced Features
- Evolution Path Mapping: Predicts when to migrate from Factory Method to more complex patterns like Abstract Factory.
- Maze Game Simulation: Uses the classic GoF Maze Game scenario to compare pattern implementations side-by-side.
- Runner-up Analysis: Explicitly identifies why the second-best pattern was ruled out to prevent architectural second-guessing.
- Pattern Combination: Recommends compatible pattern pairings, such as using Singleton with Abstract Factory.
