game-world-design

game-world-design is a skill for Codex from zenstory-ai/oh-story-dsh. It costs 168 tokens per session (1,118 once invoked), scanned A, a copy of game-world-design, MIT.

A game-design guide that turns an approved idea into a playable plan for the player experience, rules, world reactions, pacing, feedback, failure, and prototype.

In plain words
What is it for?
Use it to define the core gameplay loop, necessary systems, progression, level rhythm, player decisions, and the smallest prototype needed to test the main risk.
Why use it?
It keeps game planning focused on what the player does and how the game responds, instead of drifting into unrelated lore or implementation details.

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-world-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 yesterday.

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.

Origin

This is a copy

100% identical to game-world-design — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

游戏体验与世界设计

把选定概念变成可实现的玩家体验,不写世界观百科、工程方案或美术方向。

输入必须包含 SOURCE_BIBLE.md、已选择的 CONCEPT.mdPRODUCT_BRIEF.md。读取 world-design-method.md;确有资源、门槛或难度时再读 numeric-design-method.md

narrative-ledhybrid 的叙事层同读 narrative-design-method.mddialogue-design-method.md。需要玩家可见文案时按 game-writing-craft.md 统一声口,不为所有项目强制写长篇对白。

产物语言由 PRODUCT_BRIEF.md 锁定;未锁定时跟随对话语言,不默认产出中文。

设计原则

  • 保护 CONCEPT 的玩家承诺、experienceProfile 和不可妥协项;发现范围冲突时回上游修订。
  • 最小切片默认 10–30 分钟且不超过 brief 时长;系统预算、因果句式与关卡节拍按 world-design-method。
  • 不写文件名、函数、存储键、测试脚本、着色器或资产管线;实现结构由构建阶段决定。

输出合同

生成一个 design/GAME_DESIGN.md,保持紧凑并包含:

  1. 体验与循环合同:玩家身份、承诺、目标感受、experienceProfile、首分钟目标、3–5 个核心动词、 短/长循环和主要玩法先例,以及原作如何改变动作对象、顺序、代价和世界回应;
  2. 世界规则与成长:玩家可见/隐藏信息、行动顺序、随机性、资源或持久状态及其读取点;探索、成长、 成熟阶段新增的参与手段、可达空间或局面,以及可观察结束标记;
  3. 决策与关卡节拍:用一个场景证明最优选择会随局面翻转并写清因果权与结算权;说明路线、地标、 压力、教学、组合和检验如何制造选择;
  4. 反馈、失败与重开:输入反馈、状态变化、失败原因、下次可改之处和定义初态;
  5. 叙事附件:仅在叙事实际承载体验时写场景脊柱、人物议程、知识/证词边界、持久回响、 分支汇流和结局回收;否则写 N/A;
  6. 语言、文化与交接边界:界面语言、术语、阅读顺序、内容尺度,以及交给美术和构建的玩家效果;
  7. 可执行切片合同:最大设计风险、与风险匹配的原型形态、最小状态面、关键动作的前置/效果/观察者、 会被后续读取的事件,以及固定初态、seed、输入序列、预期状态与反馈;若概念选择了 signature_command,固定 id / label / intents / slots / validators / commit 六组最小结构,再追加 澄清与拒绝条件、委托执行链、实际结果、证物/知情变化和到期回响;
  8. 验证切片:范围、明确非目标、完整路径和会触发设计修改的观察结果。

规则优先用短表表达,不复制成平行 JSON、go/no-go 表或第二份验收矩阵。

完成检查

按 world-design-method 反向走读可执行闭环、世界回响、三段弧、重放与范围;存在叙事或专属命令时, 再按对应方法检查知识、分支、人物行动、解析候选与实际执行没有串线。只交付设计合同,不替实现选技术, 也不把趣味或平衡写成确定性 PASS。

输出交回总入口,不自行推进美术、构建或 QA。

What ships with it

6 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.

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.
