RPG API Development FAQs

Question 1

What is the RPG API Development skill?

Accepted Answer

It is a specialized capability for Claude Code designed to guide the development of gRPC-based tabletop RPG backends. It focuses on maintaining a strict data-driven architecture and high testing standards.

Question 2

How does this skill handle the separation of game rules and data?

Accepted Answer

The skill enforces a philosophy where the API acts as a game-agnostic orchestrator that stores data, while the rpg-toolkit handles all mechanical game rules (like damage calculations or stat validation).

Question 3

What is the 'Outside-In' development approach used here?

Accepted Answer

This workflow starts at the API handler layer and moves inward to services and repositories. Each layer's contract is defined and verified with tests and mocks before the next internal layer is implemented.

Question 4

Why does this skill mandate dedicated Input and Output types?

Accepted Answer

Using specific I/O structs for every function prevents breaking interface changes when adding fields, simplifies mock regeneration, and ensures a consistent contract across the entire architecture.

Question 5

When should I use this Claude Code skill?

Accepted Answer

Use this skill whenever you are working on the rpg-api codebase, implementing new gRPC handlers, creating orchestrators, or integrating game rules from the rpg-toolkit.
