How does this skill help with game balancing?

It provides a numerical design framework and templates to analyze resource symmetry, risk/reward ratios, and combat scaling, helping designers build balanced systems before implementation.

What is a GDD in game design?

A GDD (Game Design Document) is a living document that describes the vision, mechanics, story, and technical requirements of a game to align the development team throughout production.

Can I use this for existing projects with scattered notes?

Yes, the skill includes a specific consolidation workflow (/game-planner gdd consolidate) to help you organize fragmented design notes into a structured, unified master document.

What are design pillars and why are they included?

Design pillars are 3-5 core principles that guide every design decision. This skill helps you define them so you can easily evaluate whether new feature requests align with your game's core vision.

ゲーム開発

Generates and manages industry-standard Game Design Documents (GDD) with a professional planning framework.

概要

The Game Planner skill empowers developers and designers to create, audit, and consolidate professional game design documentation within Claude Code. It follows a modern two-layer architecture—separating high-level Master Documents from detailed Feature Documents—to ensure game visions stay clear, actionable, and agile. Whether you are defining core design pillars, designing complex mechanics, or performing numerical balance analysis, this skill provides the templates and structural guidance needed to maintain a 'living' GDD that serves as the single source of truth for game development teams.
