game-design

game-design is a skill for Claude Code, Codex from zhuanggenhua/BoardGame. It costs 38 tokens per session (420 once invoked), scanned A, original, MIT.

A decision framework for designing games, covering areas such as the core loop, rules, balance, levels, onboarding, interface design, player behavior, and playtesting. It directs each question to the relevant topic guidance.

In plain words
What is it for?
Use it to define a game, improve its main interactions, tune mechanics, plan levels or tutorials, design controls, and prepare playtests.
Why use it?
It helps turn a broad game-design question into a specific decision with trade-offs, risks, and a small testable next step. It also keeps design advice separate from code and asset implementation workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

game-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Game Design

本 skill 是游戏设计工作的单一入口。它只提供设计判断方法,不承载具体游戏案例库、课程讲义或项目管理长文。

Workflow

  1. 锁定用户要解决的是:立项、核心循环、机制 / 平衡、关卡 / 引导、UI / UX、玩家心理、测试,还是团队决策。
  2. 读取 references/topic-cards.md 中对应主题卡;不要加载旧讲义或案例副本。
  3. 先给直接建议,再说明取舍、风险和最小验证动作。
  4. 如果问题已经进入 BoardGame 代码、UI、测试或资源实现,回到对应项目 skill,不用本 skill 代替工程 workflow。

Topic Routing

  • 立项和框架:pillars、problem statement、80/20、范围 / 资源三角。
  • 核心循环和迭代:verbs、反馈、可重复乐趣、prototype loop。
  • 机制和平衡:flow、动态难度、奖惩反馈、min/max、倍增 / 减半。
  • 关卡、谜题和引导:能力类型、affordance、环境叙事、节奏结构。
  • UI、控制和错误:UCD、Hick、Fitts、错误分类和恢复。
  • 玩家心理和测试:认知偏差、归因偏差、playtest 方法。
  • 团队和主题:决策权、共同愿景、主题与机制协同、比例 / 张力。

Default Output

  • Target player and fantasy
  • Core loop or key interaction
  • Recommended direction
  • Main tradeoffs or abuse cases
  • Next prototype or playtest step
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
