game-concept

game-concept is a skill for Codex from zenstory-ai/oh-story-dsh. It costs 139 tokens per session (878 once invoked), scanned A, a copy of game-concept, MIT.

A game-concept guide that develops and compares three different ways to turn a novel into a playable game, then selects a prototype direction.

In plain words
What is it for?
Use it to compare game directions, define core loops and verbs, identify the closest gameplay examples, and choose whether a template or custom prototype is needed.
Why use it?
It makes the key design trade-offs visible before building, including the player’s role, repeated actions, pressure, failure, and how the source material changes gameplay.

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-concept 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 today.

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-concept — 0 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

游戏概念设计

决定做成什么游戏,不写代码、数值表或逐场关卡脚本。

读取 concept-method.md。输入必须包含 SOURCE_BIBLE.md 与 PRODUCT_BRIEF.md;缺任一项就停止并说明缺口,不代替上游补写。

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。

决策边界

直接继承 brief 已锁的平台、输入、受众、分级、时长、目标市场和非目标;发现它们与原作明显冲突 时回总入口修订,不在概念阶段静默改值。原作语言、文化语境、目标市场和界面语言分别处理,不从 其中一个自动推出另一个。

互动叙事是成熟玩法,不因以阅读和对白承载就降低标准;它的动词可以是读局面、追问、比对信息、 表态、隐瞒、交出与承担回响。

概念还要判断验证形态:可用成熟交互语法表达时说明“已有语法 + 原作如何改变它”;核心依赖实时手感、 空间、视线、物理或独特操作时明确走自定义灰盒。不要把文本原型当所有体验的统一前置层,也不要因有 模板可用就让模板替原作决定玩法。

比较范围

先列 brief 的锁定维度和仍开放的维度,只比较能揭示真实取舍的方向,不凑概念数量或差异维度。 仅在方向仍开放时考察可信替代;用户已选定方向或不存在有效替代时说明原因,改为验证该方向的风险, 不重开选择。

选择

先按 concept-method 的硬否决逐个淘汰,不计算总分,再按其比较维度选择。quick 自动选证据最强的 方向;director 只对尚未决定的方向给出推荐并等待用户选择。

输出

生成一个 concepts/CONCEPT.md,只含:

  1. brief 锁定值与开放维度;
  2. 体验承诺及其可观察现象和失败现象;
  3. 紧凑先例说明;
  4. 候选概念卡:主类型、experienceProfile、借用/拒绝的玩法先例、核心动作与循环、压力、失败、 世界响应;说明玩家身份如何形成反复行动、执行阻力与可观察变化。 signature_command 按方法「身份专属命令」写值或 N/A;最后说明原作张力如何由玩家行动体现、 招牌画面、最小验证切片、最大风险和否决观察;
  5. 硬否决结果、关键取舍、推荐与选择状态;
  6. 选定方向的玩家能动性合同、不可妥协体验承诺;
  7. 最小验证问题与开放问题。

narrative-led 或 hybrid 的叙事层还要选择一种分支结构语法并说明内容预算。交接前确认选定方向 可在 brief 范围内做成完整切片。

Files

What ships with it

2 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.
