One Sentence to Game (prompt, iterate, check)
/one-sentence-to-game
A GameSkill original for any model: a round-1 prompt that turns one sentence into a small finished browser game, a one-change-per-round loop with a creation log, a reusable spec template, and a headless checker that reports console errors, blank frames and dead controls as PASS or FAIL. It does not promise one-shot.

我们测过
在 Node 20 + Chrome 156 headless (any model writes the game) 上通过 26/26 项检查（2026-10-28）：能触发、有可运行示例、有截图和自检清单、单一职责、中英文文档齐全。触发检查是把提示词和 skill 描述做匹配，不是真实 agent 运行。

自检清单
- 没有向用户承诺一次生成 / Did not promise the user a one-shot result
- 每一轮只改一处，并记录在 CREATION.md / One change per round, logged in CREATION.md
- 每一轮都在桌面和手机上运行 check-game / check-game run on desktop and --mobile every round
- 看过四张截图并亲自玩过 / Looked at the four screenshots and played it
- 完成后写了复用规格 / Wrote the reusable spec once the game was good
- npm test 和 npm run test:browser 都通过 / npm test and npm run test:browser pass
中文指南
这个 skill 做什么
GameSkill 原创（MIT），适用于任何模型。把一句话的游戏点子变成一个小而完整的浏览器游戏，并且安全地迭代：第一轮提示词模板（沿用经典规则、单文件、无外部素材、键盘和触屏、能重开、“小而完整胜过大而粗糙”、不问澄清问题）、首轮检查清单、每轮只改一处的迭代流程和轮次记录、从成品倒推的复用规格模板，以及一个无头 Chrome 检查器：打开游戏、记录控制台和网络错误、检测空白首帧、模拟按键并比较截图判断操作是否有反应，输出 PASS/FAIL 和 JSON 报告。它不承诺一次生成就能成功。
什么时候用
- 用户说“给我做一个关于……的游戏”
- 想用 GPT、Claude、Gemini 等模型一次生成游戏
- 生成的游戏越修越坏
怎么装
下载本页的 ZIP，把 one-sentence-to-game/ 文件夹放进 .claude/skills/（Claude Code）或 .agents/skills/（Codex、Cursor），重启 agent。检查器需要 npm ci（puppeteer-core）和 Chrome。
最小示例
node tools/check-game.mjs fixtures/good 输出 PASS；fixtures/broken（缺素材 + 调用不存在的函数）和 fixtures/frozen（画面正常但没有任何反应）输出 FAIL 并说明原因。加 --mobile 用手机尺寸检查。
我们怎么测的
npm test 跑 6 个单元测试：PNG 解码（所有行过滤器）、空白检测、帧差、按键脚本、判定规则和 favicon 噪音。npm run test:browser 在无头 Chrome 里对三个样例跑检查器共 6 项，确认好的通过、坏的失败、理由正确，无法访问的地址返回退出码 2。

适合
- Turning a one-line game idea into a playable browser game
- Iterating on a generated game without breaking what already works
- Checking generated games automatically before a human plays them
不适合
- Large multi-file projects with build tools
- Judging whether a game is fun (PASS only means not obviously broken)
试试这条提示词
Make me a small browser game where a moth collects lanterns at night, then check it actually runs.关于这个 Skill
A GameSkill original for any model. One sentence becomes a round-1 prompt; each later round changes one thing; a headless checker says PASS or FAIL after every round. It is honest that most good generated games take several rounds.
Agent steps
- Round 1 from
templates/PROMPT.md: classic core rules, one file, no assets, keyboard and touch, restart, no questions. - Check before looking:
check-gameon desktop and--mobile, then play for two minutes with the checklist. - One change per round, written as an observation plus the expected result.
- Re-check and log every round; revert when a round makes things worse.
- Three strikes: shrink the feature or spec that one system.
- Write the reusable spec from the finished game.
- Never promise one-shot; report rounds and hand edits.
Common errors it fixes
- Trusting "done" without opening the game.
- Multi-fix prompts that rewrite and break a working game.
- Missing assets, CDN links and dead controls that nobody noticed.

Kart Drift Boost (tiers, windows, ramps)
A GameSkill original: arcade kart drift-boost rules that reward skill. Drifts charge three tiers, release opens a 0.85 s window you must press in, counter-steer adds a CUT bonus, ramps give one air and one landing boost, boosts take the maximum instead of stacking, and walls cancel everything pending.
