What it does

Web Prototype is an agent skill from sanqiufong/slides-from-anything. General-purpose desktop web prototype. Single self-contained HTML file built by copying the seed assets/template.html and pasting section layouts from references/layouts.md. Default for any landing / marketing / docs / SaaS page when no more specific skill matches.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `references/checklist.md` and `references/layouts.md`).

The repository describes itself as: Turn anything into slides. The licence is Apache-2.0.

Example prompts

  • “/web-prototype”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Pre-flight (do this once before writing anything)
  2. Copy the seed
  3. Plan the section list
  4. Paste and fill
  5. Self-check
  6. Emit the artifact

What it can do on your machine

Read from SKILL.md and the folder at commit 65da4ac. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Web Prototype loads about 1k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 453 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Web Prototype Skill

Produce a single, self-contained HTML prototype using the bundled seed and layout library — not by writing CSS from scratch. The seed already encodes good defaults (typography, spacing, accent budget). Your job is to compose it.

Resource map

web-prototype/
├── SKILL.md                ← you're reading this
├── assets/
│   └── template.html       ← seed: tokens + class system + chrome (READ FIRST)
└── references/
    ├── layouts.md          ← 8 paste-ready section skeletons
    └── checklist.md        ← P0/P1/P2 self-review

Workflow

Step 0 — Pre-flight (do this once before writing anything)
  1. Read assets/template.html end-to-end — at minimum through the <style> block. The class inventory at the top of references/layouts.md lists every class that must be defined there; if one is missing, add it to <style> rather than re-defining it inline on every section.
  2. Read references/layouts.md so you know which section skeletons exist. Don't write a section type that isn't covered — pick the closest layout and adapt.
  3. Read the active DESIGN.md (already injected into your system prompt). Map its colors to the six :root variables in the seed; don't introduce new tokens.
Step 1 — Copy the seed

Copy assets/template.html to the project root as index.html. Replace the six :root variables with the active design system's tokens. Replace the page <title> and the topnav brand.

Step 2 — Plan the section list

Pick layouts before writing copy. Default rhythms (from layouts.md):

Page kindDefault rhythm
Landing1 hero → 3 features → 4 stats or 5 quote → custom split → 6 cta
Marketing / editorial1 hero-center → 7 log list → 6 cta
Pricing1 hero-center → 8 comparison table → 6 cta
Docs index1 hero-center → 7 log list (sections of docs) → 6 cta

State the chosen list in one sentence to the user before writing — they can redirect cheaply now and not after 200 lines of HTML.

Show full SKILL.md (193 more words)Show less
Step 3 — Paste and fill

For each chosen layout, copy the <section> block from layouts.md into <main id="content"> of your index.html. Replace bracketed [REPLACE] strings with real, specific copy from the user's brief. No filler — if a slot is empty, the section is the wrong choice; pick a different layout.

Step 4 — Self-check

Run through references/checklist.md top to bottom. Every P0 item must pass before you move on. P1 items should pass; P2 are bonus.

Step 5 — Emit the artifact

Wrap index.html in <artifact> tags. One sentence before describing what's there. Stop after </artifact>.

Hard rules (the seed protects most of these — don't fight it)

  • Single accent, used at most twice per screen. Eyebrow + primary CTA is the default budget.
  • Display font is serif (Iowan Old Style / Charter / Georgia in the seed). Sans for body. Mono for numerics, captions, eyebrows.
  • Image placeholders, not external URLs. Use the .ph-img class — never link to a stock photo CDN.
  • Mobile reflow already works via the seed's media query at 920px. Don't break it by adding fixed widths.
  • data-od-id on every <section> so comment mode can target it.

Output contract

<artifact identifier="kebab-case-slug" type="text/html" title="Human Title">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact. Nothing after.

To copy it by hand, put the folder in .cursor/skills/web-prototype, .gemini/skills/web-prototype, .github/skills/web-prototype and .opencode/skills/web-prototype in your project.

What does Web Prototype need to run?

SKILL.md names no scripts, command-line tools or credentials: Web Prototype is instructions for the agent only.

Does Web Prototype access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Web Prototype safe to install?
