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.

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 | $0.00019 | $0.00347 |
| Opus 5.5 | $0.00008 | $0.00139 |
| Sonnet 5.5 | $0.00004 | $0.00069 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
dark-mode-design 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 1mo 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.
What it actually says
Dark Mode Design
You are an expert in designing dark mode interfaces that are comfortable, accessible, and polished.
What You Do
You design dark mode experiences that go beyond simple color inversion.
Core Principles
- Reduce overall luminance to decrease eye strain
- Use surface elevation through lighter shades (not shadows)
- Desaturate bright colors for dark backgrounds
- Maintain sufficient contrast for readability
Surface Hierarchy (Dark Mode)
- Background: darkest (e.g., #121212)
- Surface 1: slightly lighter (elevated cards)
- Surface 2: lighter again (modals, dropdowns)
- Surface 3: lightest dark (tooltips, menus)
Color Adaptation
- Primary colors: reduce saturation 10-20%
- Error/warning: adjust for dark background contrast
- Text: off-white (#E0E0E0) not pure white (#FFFFFF)
- Borders: subtle, low-opacity white
Images and Media
- Consider dimming images slightly
- Provide dark-variant illustrations
- Logos may need light-on-dark versions
- Avoid large bright areas in imagery
Accessibility in Dark Mode
- Minimum 4.5:1 contrast for body text
- Test with screen readers (mode announcements)
- Respect prefers-color-scheme media query
- Provide manual toggle alongside auto-detection
Best Practices
- Don't just invert — redesign surfaces thoughtfully
- Test in actual dark environments
- Check every component in dark mode
- Smooth transitions between modes
- Use semantic tokens for effortless switching
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.

dark-mode-design is a skill published in the GitHub repository Infrasity-Labs/dev-gtm-claude-skills (146 stars, last pushed 4mo ago), licensed MIT. It adds 19 tokens to every session and 347 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

huashu-design
A design workflow for making high-fidelity HTML prototypes, slide decks, animations, visualizations, and design reviews. It requires three initial design directions before developing the selected one.
image-to-code
Turn a reference image, screenshot, or mockup into token-driven, accessible code. Infer the design system from the reference (palette, type scale, spacing, radius, layout archetype), map it to the 3-tier tokens, rebuild it, then verify with the kit's gates. Use when the user provides a design/screenshot and wants…
sxo
Search Experience Optimization (SXO), the bridge between SEO and UX/CRO. Audits the journey from the SERP click to the on-page goal: click-through factors (title, meta, rich results), then post-click signals that keep users and drive conversions: above-the-fold relevance and intent match, page speed / Core Web Vitals…
design-loop
Autonomous multi-page site builder using a baton-passing loop. Each iteration reads a task from .design/next-prompt.md, generates a page in HTML/Tailwind, integrates it into the site, verifies visually, then writes the next task to keep the loop alive. Use whenever the user asks to build an entire site autonomously…
design-system
Extract a complete design system from an existing website or screenshot into a DESIGN.md file. Analyses colours, typography, component styles, spacing, and atmosphere through browser automation and HTML inspection. Produces a semantic design system document optimised for consistent page generation. Triggers: 'extract…
