Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00163 | $0.05405 |
| Opus 5 | $0.00081 | $0.02703 |
| Sonnet 5 | $0.00033 | $0.01081 |
| Haiku 4.5 | $0.00016 | $0.00541 |
Grade A, and why
game-design-proposal-writer 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.

Game Design Proposal Writer
使用本 skill 时,把已经存在的调研材料、创意方案、玩家承诺、竞品证据、体验诊断、ED 实验、生产约束和商业目标,整理成可以被制作人、老板、发行、投资人、合作方或独立团队成员评审的游戏策划案/独游设计案。
它不是普通 GDD 生成器,也不是把一句话创意扩写成长文的工具。创意还没有被拆出 design nucleus 时,优先提醒使用 game-concept-architect;样本体验还没有证据层时,优先提醒使用 game-experience-analyzer;需要一周体验实验时,优先提醒使用 game-experience-density-optimizer。本 skill 的核心工作是把上游产物变成一份有受众、有论证、有取舍、有风险、有下一步决策的文档。
如果用户给的是一句话创意,但明确要求“写策划案/立项案/独游设计案/pitch/GDD”,不要直接跳过上游。先调用 game-concept-architect 产出 concept brief、player-promise-contract、core loop、scope gate 和 validation plan,再用本 skill 成案。最终文档要标注“上游概念由本轮自动生成,证据等级仍为 assumption / needs_research”。
用户可在自己的环境中处理真实项目、私有项目或客户项目。准备公开仓库案例时,只能使用 synthetic、公开或明确授权的材料,并在发布前执行 Human Gate。
什么时候使用
当用户想写、改写、压缩或评审以下材料时,使用本 skill:
- 商业游戏策划案、立项案、产品方案、项目建议书。
- 独立游戏设计案、GDD、Steam/发行 pitch、Demo/Vertical Slice 方案。
- 给老板、制作人、发行、投资人、合作方或团队看的项目说明。
- 把调研报告、创意方案、竞品分析、玩家承诺和验证计划整合成一份文档。
- 把一句话创意先经
game-concept-architect拆成概念契约,再整理成正式策划案。 - 把玩法脑图、系统设计脑图、xmind、OPML、Markdown 大纲、Word/Excel 导出的设计表,整理成可落地策划案。
- 审核、重写、压缩或改进已有商业策划案、独游设计案、GDD、pitch outline、vertical slice 文档。
- 把过长、幻想化、没有决策点的设计案改成可评审版本。
- 需要说明平台、商业模式、目标用户、核心循环、系统范围、制作成本、里程碑和风险。
以下请求要强触发:
- 写一份商业游戏策划案
- 写一份独游设计案
- 写 GDD / Game Design Document
- 写立项案 / 项目方案 / 产品方案 / pitch deck 文案
- 给发行 / 投资人 / 老板看的游戏方案
- 把这个创意整理成正式策划案
- 只有一句话创意,帮我写成策划案 / 立项案 / pitch
- 这个 xmind / 脑图 / 系统图帮我做成可落地策划案
- 审核这份策划案 / 改进这份 GDD / 帮我把已有方案改成能评审的版本
- 把调研和创意合成一份文档
- 改成能立项评审的版本
- 做 vertical slice 文档 / demo 方案
不适用场景
如果用户只有一句话创意,并且目标是判断创意是否成立,应优先使用 game-concept-architect。如果用户同时要求产出策划案,本 skill 应作为第二步,在 game-concept-architect 输出后接续成案。
如果用户给的是录屏、PV、截图或试玩反馈,并希望诊断体验问题,应优先使用 game-experience-analyzer。
如果用户要的是首局节奏、反馈、具身感、氛围、认知负荷、留存或一周 A/B 实验,应优先使用 game-experience-density-optimizer。
如果用户只是要宣传文案、商店页短描述、众筹页面、PR 文案或广告脚本,本 skill 可以给文档中的定位和承诺,但不应替代专门的 marketing copywriting。
项目内上游产物审核门
写案前先做一次项目内协作自检,但不要把本 skill 退化成泛品类设计回答。本 skill 只负责把项目内其他 skill 或用户已有材料收束成评审文档,不继承项目外的全局设计总师口径。
primary_category:先判断主品类/副品类、平台、商业模型和项目阶段。core_player_action:先看玩家反复做什么,再看题材、系统和文案。anti_pollution:商业案、独游案、Steam pitch、手游立项、Demo 文档不要互相套模板。proof_of_play:对外 pitch 必须说明 playable build、gameplay video、demo、vertical slice、玩家反馈或指标的状态。scope_feasibility:所有系统、内容、预算和里程碑都必须受团队能力约束。negative_example:至少写一个看似相似但不应采用/不应投递的反例。

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.
- 11d ago First seen · 337 lines · 163 tokens per session scan A 9ac38dbce3b3
game-design-proposal-writer is a skill published in the GitHub repository DY-2026/GameDesignOS (385 stars, last pushed 25d ago), licensed MIT. It adds 163 tokens to every session and 5,405 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
