What problem does it solve?
The skill helps developers separate pure logic from side effects to improve testability and maintainability.
Core Features & Use Cases
- Enforces the Gather → Process → Persist pattern to clearly separate data gathering, processing, and persistence.
- Identifies pure vs side-effecting code and provides a checklist to guide refactoring.
- Supports testing practices that minimize nondeterminism and external dependencies.
Quick Start
Refactor a small function to extract pure logic and isolate I/O in a thin orchestrator, then run tests.
