What is web-design-picker?

A website concept review package that creates three responsive design directions, a page for switching between them, and a searchable catalog of design assets. It also prepares preview files and deployment handoffs.

It helps create alternative website designs, client review pages, full-screen previews, asset catalogs, and static deployment ZIP files.

It replaces scattered mockups and files with a reviewable package that clients can compare and receive. It keeps each design direction and its assets organized for handoff.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Subtle instructions detected that may alter agent decision-making or introduce hidden biases.

Fix: Review content for implicit steering or bias. Ensure instructions are explicit and align with the skill's stated purpose.

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	$0.00028	$0.02544
Opus 5	$0.00014	$0.01272
Sonnet 5	$0.00006	$0.00509
Haiku 4.5	$0.00003	$0.00254

Security

Grade B, and why

web-design-picker scanned grade B with 1 finding 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 6d ago.

The scan reads SKILL.md. This mod also ships 16 executable files (scripts/_common.py, scripts/browser_qa.py, scripts/build_picker.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.

Subtle steeringmediumPrompt injection

Instructions that bias recommendations or shape behaviour without the user noticing.

Follow [the QA and Cloudflare Drop checklist](references/qa-and-cloudflare-drop.md). Never tell the user a site has been deployed when only a ZIP was created.

How it starts

The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web design picker

Build a complete website-concept review package rather than isolated mockups. The default deliverable is three materially different, responsive website directions; a review shell that switches among them without losing the presentation context; a full-screen presentation mode; a searchable asset catalog with per-format, per-family, and download-all controls; two primary release archives; and supporting review, source, and full-handoff archives.

When invoked for an actual website project, perform the work. Do not stop at a strategy document unless the user asks only for strategy.

Default output contract

Create:

Three standalone direction source pages in src/concepts/, built into dist/concepts/.
One generated review picker at dist/index.html.
One generated asset catalog at dist/design-assets.html.
Direction-specific logos, favicons, palettes, design tokens, and supporting graphic elements.
Optimized client media when source video or animation is supplied.
Desktop and mobile preview images when browser automation is available.
A lean static deployment ZIP with index.html at its root.
A separate complete design-assets handoff ZIP.
A machine-readable and human-readable QA report.

Use scripts/web_design_picker.py as the unified command-line entry point for scaffolding, building, validating, browser-testing, and packaging. Read the workflow reference before beginning a full project.

Non-negotiable rules

Build three distinct design theses, not one template with three palettes.
Each direction must differ in information architecture, typography, spacing, geometry, media treatment, interaction, and emotional register.
Keep each concept independently usable as a static page with its own title, viewport metadata, favicon, accessible navigation, and responsive layout.
Use real supplied content and media as evidence. Do not invent capabilities, clients, metrics, certifications, software compatibility, or testimonials.
Treat trademarks and product names accurately. Never imply an affiliation that does not exist.
Do not use stock imagery merely to fill a composition. Prefer client assets, purposeful diagrams, custom vector elements, crops of real work, or restrained typography.
Avoid generic AI-site styling. Apply the anti-slop guardrails and run scripts/slop_lint.py before packaging.
Do not make a fake contact flow. A prototype form may download a structured brief or clearly state that submission is not connected. Production submission requires a real endpoint.
Do not bundle font files for handoff unless the user owns redistribution rights. Prefer system fonts, licensed web delivery, or outlined logo artwork.
Every direction and the review shell must include a favicon set.
Preserve reduced-motion preferences and keyboard operation.
Do not place a wrapper folder inside the Cloudflare Drop ZIP. The first archive entry must be index.html.
Keep the deployment ZIP lean. Do not place the complete handoff ZIP inside it. The asset page should assemble ZIP downloads client-side from individual static files.

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.
