reusability

What problem does it solve?

This Skill helps developers identify and remove duplicated logic across a codebase by extracting stable patterns into reusable, secure abstractions that prevent divergence and reduce maintenance burden.

Core Features & Use Cases

• Signal-based guidance: when to extract (copy-paste with small changes, a second similar implementation, or a component growing to handle multiple cases).
• Proven patterns: parameterize variations, extract generic hooks for shared async or stateful logic, prefer composition over inheritance, and create pure utilities.
• Security by default: enforce validation and trust boundaries at the abstraction layer so shared utilities do not skip server-side checks.
• Use Case: replace near-identical UI cards with a single parameterized EntityCard, consolidate repeated fetch logic into a useAsync hook, and ensure repository-level schema parsing.

Quick Start

Consolidate two similar components into a single parameterized component, extract shared fetch logic into a generic hook, and add explicit validation at the abstraction boundary.
