Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/vinvcn/mattpocock-skills-zh-cn --skill prototype- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads prototype automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
Security audits
Independent scans of the skill's instructions and bundled files.
SKILL.md
The instructions your agent reads when the skill is triggered.
原型
Prototype 是用来回答一个问题的 throwaway code。问题决定形状。
选择分支
先识别正在回答哪个问题：来自用户 prompt、周围代码，或在用户在线时直接询问：
- "Does this logic / state model feel right?" → LOGIC.md。构建一个单一、可分享的 HTML 文件（free-play buttons 加 tabbed guided walkthroughs），推动 state machine 跑过纸面上难以推理的 cases，而且非开发人员也能驱动它。
- "What should this look like?" → UI.md。在单一路由上生成几种差异很大的 UI variations，并通过 URL search param 和浮动底栏切换。
这两个分支会产出非常不同的 artifacts；选错会浪费整个 prototype。如果问题确实模糊且用户不可达，默认选择更匹配周围代码的分支（backend module → logic；page 或 component → UI），并在 prototype 顶部说明假设。
两个分支通用的规则
- 从第一天就是 throwaway，并明确标记。 Prototype code 要靠近它实际会被使用的位置（放在被 prototype 的 module 或 page 旁边），这样上下文清楚；但命名要让随手读代码的人看出它是 prototype，不是 production。对 throwaway UI routes，遵守项目现有 routing convention；不要发明新的顶层结构。
- 运行毫无负担。 UI prototype 从项目 task runner 中的一条命令启动：
pnpm <name>、python <path>、bun <path>等。Logic demo 则是用户双击即可打开的单个 HTML 文件。无论哪种，启动都不需要动脑。 - 默认不持久化。 State 保存在内存中。Persistence 是 prototype 要_检查_的东西，不该成为依赖。如果问题明确涉及 database，就用 scratch DB 或带有清晰 “PROTOTYPE, wipe me” 名称的本地文件。
- 跳过 polish。 不写 tests，不做超过“能跑起来”所需的 error handling，不做 abstractions。重点是快速学到东西。
- 暴露 state。 每次 action（logic）或每次 variant switch（UI）后，打印或渲染完整相关 state，让用户看到发生了什么变化。
- 完成后 capture。 把验证过的 decision 折进真实 code，然后把 prototype 本身作为 primary source 保存：commit 到 main 之外的 throwaway branch，并在 implementation issue 上留下指向该 branch 的 context pointer。同时在 issue 或 commit 中 capture answer，也就是 verdict 与它解决的问题。Main branch 只保留验证过的 decision。
FAQ
What does the prototype skill do?
构建一次性原型来回答一个设计问题。适用于用户想验证某个 state model 或 logic 是否感觉对，或探索 UI 应该长什么样时。
How do I install prototype?
Run npx skills add https://github.com/vinvcn/mattpocock-skills-zh-cn --skill prototype in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/prototype/ (personal) or .claude/skills/prototype/ (project).
Which AI agents can use prototype?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is prototype safe to install?
Security partners have reviewed it: Gen Agent Trust Hub passed; Socket passed; Snyk passed. As with any skill, read the SKILL.md and bundled scripts before installing.
Who maintains prototype?
It is published by vinvcn in vinvcn/mattpocock-skills-zh-cn. It has 5,793 recorded installs.

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). Also covers auditing an existing composition's choreography (animation map) and 24 named text-animation effects. HyperFrames-native: single paused timeline, seek-safe, deterministic.
