What is page-prototype?

An HTML wireframe tool for making a rough, clickable model of one page or screen. A wireframe shows structure and interactions with simple gray boxes rather than finished visual design.

Use it to prototype pages with sliders, tabs, accordions, toggles, modals, and mobile menus, then open the result in a browser.

It lets you test page structure and basic interactions before building the real interface. It avoids treating a rough prototype as production UI.

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.

agentmods

npx agentmods add skills/vkirill/claude-lane-stack/page-prototype

Any agent

npx skills add VKirill/claude-lane-stack --skill page-prototype

Clone the repo

git clone --depth 1 https://github.com/VKirill/claude-lane-stack

Made for: Claude Code, Codex.

Or install lane-stack, the plugin that ships this one along with the rest of its 53 skills, 4 commands, 17 agents, 1 hook.

Token cost

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	$0.00086	$0.01769
Opus 5	$0.00043	$0.00885
Sonnet 5	$0.00017	$0.00354
Haiku 4.5	$0.00009	$0.00177

Measured today against content hash 7ff06735288f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-05, from the pricing page.

Security

Grade A, and why

page-prototype 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 today.

The scan reads SKILL.md. This mod also ships 2 executable files (references/kit/proto.js, references/publish.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Page prototype

One HTML file per screen + shared kit. Gray boxes. Real copy if a brief exists. Open in a browser.

Not a designed page. Not a writer lane. Not Vue. Not npm.

Info (print and stop)

If $ARGUMENTS is info: print the block below verbatim, then stop.

page-prototype — серый HTML-вайрфрейм + общий kit.

Update INDEX. If a copy brief exists, one-line prototype:.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
