law-of-demeter

What problem does it solve?

This Skill helps developers avoid deep object access and chained method calls by enforcing the Law of Demeter, reducing coupling and fragility in codebases.

Core Features & Use Cases

• Promotes explicit data access: Replaces nested property chaining with well-defined accessors.
• Refactoring guidance: Provides patterns to move logic from chained calls into owner methods.
• Use Case: When you see code like user.getProfile().getAddress().getCity(), apply this skill to introduce a getCity() method on User or related objects.

Quick Start

Detect chained access patterns and replace them with explicit accessor methods. Example: replace order.customer.paymentMethod.last4 with order.getPaymentLast4() by adding a getter on Order or Customer as appropriate.
