# web-technique-to-skill Turns a visual or interaction technique you already built into a reusable web-design skill, with a demo that proves both the mechanism and the visual fidelity. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 1100 installs · ★ 7001 - Author: MengTo - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/MengTo/Skills/tree/HEAD/agent-skills/codex/web-technique-to-skill/SKILL.md - Updated: 2026-10-25 - HTML: https://affpapa.org/en/nevibecode/skills/web-technique-to-skill ## What it does The skill starts from working code, not from prose. It pulls out one mechanism per skill — the single thing that, if removed, makes the effect stop working. Everything else gets sorted: staging (palette, copy, layout, brand) stays in the demo, while project selectors and one-off asset paths go nowhere. A page that turned out well usually holds several techniques, so package them separately or each one gets diluted. What's inside is a set of rules, not scripts. The mechanism gets named in one sentence, the demo gets a concrete name in the visible `h1` and browser ``, and the verified stack sits right above it: runtime, renderer, technique layer. The skill insists you check imports and context creation in the source instead of guessing from the look — `getContext('2d')` is Canvas 2D, not a shader. Numbers ship as they are; "subtle" is unusable, `0.3–0.5` is a starting point. Expensive gotchas get their own rules: colour space, layout timing, ordering, platform quirks. The opening lines declare a boundary — which neighbouring skill to reach for instead. Before you start, search `agent-skills/*/*/SKILL.md`; if a skill already covers the mechanism, extend it rather than adding a near-duplicate. The source text is truncated, so I won't speak for the sections beyond that. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add MengTo/Skills --skill web-technique-to-skill -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/web-technique-to-skill/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/web-technique-to-skill/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add MengTo/Skills --skill web-technique-to-skill -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/web-technique-to-skill/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add MengTo/Skills --skill web-technique-to-skill -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/web-technique-to-skill/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install MengTo/Skills web-technique-to-skill ``` 2. **Manually: put the files in place** - File: `.github/skills/web-technique-to-skill/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add MengTo/Skills --skill web-technique-to-skill -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/MengTo/Skills --path agent-skills/codex/web-technique-to-skill ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/web-technique-to-skill/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add MengTo/Skills --skill web-technique-to-skill -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/MengTo/Skills/tree/HEAD/agent-skills/codex/web-technique-to-skill/SKILL.md ## When to use it - extract one mechanism from a finished page and package it as a skill - separate demo staging from the reusable mechanism - record the verified stack instead of guessing from the look - carry real constants and ranges instead of adjectives - declare a boundary against the nearest skill to avoid duplicates ## Example prompts - Break down this canvas effect and build a web-technique-to-skill skill from it - Name the mechanism in one sentence and put the stack above the demo title - Check the imports and context creation, then state the runtime and renderer ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE b01b090cc2888ab6 ```text --- name: web-technique-to-skill description: Turn a visual or interaction technique you already built into a reusable web-design skill, by isolating the one mechanism that makes it work while reproducing its approved reference exactly around that focus, and packaging it with a demo that proves both the mechanism and the visual fidelity. Covers finding the mechanism, naming the technique plainly, disclosing the verified runtime and renderer, auditing reference layers, carrying real numbers instead of adjectives, preserving owned staging, keeping expensive gotchas, declaring the boundary against neighbouring skills, and browser-verifying before claiming it works. Use when a page, canvas scene, shader, scroll effect, layout system, or hover interaction turned out well and should become a skill rather than staying in one project. --- # Web Technique to Skill Start from working code, not from prose. Reach for `article-prompts-to-skills` when the source is an article or a prompt pack that describes behavior. Reach for this when you built the thing, it works, and the knowledge is currently trapped in one file. Extract one mechanism per skill. A page that turned out well usually holds several; package them separately or each one gets diluted. Treat this as the living quality contract for every web-technique skill. On every creation or revision, audit this skill too. If the work exposes a missing fidelity rule, failure mode, packaging constraint, or verification step, update this contract in the same scoped change instead of solving it only inside one child skill. ## Name the mechanism in one sentence Write the sentence before you write anything else: *the one thing that, if removed, makes the effect stop working.* If you cannot write it, you have a look, not a mechanism, and there is no skill here yet. The sentence decides everything downstream. For a leaf fall it is "the tumble crosses edge-on, and that instant of near-disappearance is what the eye reads as a leaf" — so the sprite artwork, the palette, and the night scene are all staging, and the tumble is the skill. ``` END THIRD-PARTY FILE b01b090cc2888ab6 The third-party file has ended.
