What is tool-design-style-selector?

A design-planning tool that examines a project and creates a design system, a shared set of rules for colors, fonts, spacing, and layout.

Use it to preserve an existing style or choose from preset styles, then document the project’s visual rules in design-system.md.

It helps a team choose a consistent visual direction instead of making interface decisions piecemeal.

SkillSpector: 1 finding, up to medium

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 →

medium Rogue Agent · line 51
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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	$0.00106	$0.02125
Opus 5	$0.00053	$0.01063
Sonnet 5	$0.00021	$0.00425
Haiku 4.5	$0.00011	$0.00213

Security

Grade A, and why

tool-design-style-selector 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 12d ago.

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.

Design Style Selector

Scan project, identify intent, recommend and deploy the most suitable design system style.

Style Presets

This skill can either:

Preserve existing style and extract it into design-system.md (recommended when the project already looks “mature”), or
Apply one of 30 preset styles and generate design-system.md.

Style files live in styles/ and are indexed in:

styles-index.md (ID → filename → theme)

Quick examples of presets:

05-saas (B2B tools, dashboards)
08-swiss-minimalist (clean hierarchy, corporate)
13-neo-brutalism (bold, indie/creative)
19-minimal-dark (focus mode, dev tools)

Execution Flow

Step 1: Scan Project

Scan the following files to identify project intent:
- README.md / README
- package.json / pyproject.toml / Cargo.toml
- Existing Claude.md / agent.md / AGENTS.md
- src/ or app/ directory structure
- Existing style files (tailwind.config, globals.css)
- Brand assets (logo, favicon)

Step 2: Analyze Intent

Extract the following information:

Project Type: SaaS/corporate site/e-commerce/blog/tool/game/...
Target Users: Developers/enterprises/consumers/children/professionals/...
Brand Tone: Professional/playful/luxury/minimal/bold/...
Tech Stack: React/Vue/Next.js/static site/...
Existing Design Constraints: Current colors/fonts/component libraries

Step 2.5: Existing Style Gate (For existing projects, first determine whether to "preserve style")

Purpose: Avoid forcing a reskin on projects that are "already good-looking/already branded", preventing unnecessary UI rework and cognitive costs.

When a repo already has UI, first do a quick "style maturity" assessment and write out evidence (don't be purely subjective):

Signals of mature style (meeting multiple criteria is sufficient):

Has clear design tokens: tailwind.config.* has fairly complete color/font/radius/shadow/spacing config, or :root CSS variables form a system
Component library/component style is consistent (buttons/inputs/cards etc. semantic components have high reuse)
Layout and spacing are basically consistent across pages (rarely see hardcoded color values/pixels/inline styles)
Has brand assets (logo, favicon, brand colors) consistently reflected in UI

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.
