What problem does it solve?

This Skill provides essential procedural knowledge and constraints for writing and debugging at code, ensuring consistency and safety in AI-assisted development.

Core Features & Use Cases

• Enforces explicit return types, alias imports, and explicit effects declarations to improve readability and mockability.
• Provides a comprehensive guide to syntax, control flow, error handling, and tooling conventions for at programs.
• Serves as a reference for building reliable agent-focused code with deterministic tests and safe sandboxing.

Quick Start

Create a minimal at program that demonstrates explicit return types, aliased imports, and a Result-based error path, then run at check to verify type- and lint-diagnostics.
