MengTo/Skills is a collection of reusable instruction folders that teach coding agents workflows for interface design, games, frontend systems, automations, and agent loops. Designers and developers use the skills to turn references, prompts, and implementation habits into repeatable work. The catalogue contains the project’s skills and supporting instruction.
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.

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 | $0.00032 | $0.00839 |
| Opus 5 | $0.00016 | $0.00419 |
| Sonnet 5 | $0.00006 | $0.00168 |
| Haiku 4.5 | $0.00003 | $0.00084 |
Grade A, and why
dark-blue-contrasting-clean 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 8d 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.

Dark Blue Contrasting Clean Skill
Use When
- Create a dark-blue clean design system with strong contrast, cobalt gradient feature blocks, crisp framed structure, and restrained premium glow.
Workflow
Scope
- Apply this as a full design-system direction across page background, framing rails, hero or CTA bands, cards, link groups, navigation, and motion.
- Use it when the interface should feel premium, dark, crisp, and blue-led, with strong contrast between deep navy surfaces and brighter cobalt focal regions.
- This is not an airy cloud-blue system and not loud neon sci-fi. It should stay clean, architectural, and high-contrast.
Visual target
- Build the page on a near-black navy base, using dark blue-black backgrounds with subtle tonal variation rather than flat pure black.
- Introduce one or more prominent cobalt or royal-blue feature blocks as contrast moments, such as hero banners, CTA bands, spotlight cards, or product sections.
- Use white typography and pale-blue support text over the dark system so the contrast feels sharp, readable, and premium.
- Add thin outer rails, border-x container lines, small corner squares, and quiet framing detail so the layout feels disciplined and engineered.
- Let blue glow stay soft and localized, appearing in background blooms, button emphasis, or tiny live indicators instead of flooding the whole page.
Implementation guidance
- Prefer a framed max-width shell or inner container with vertical boundary lines and subtle corner markers holding the composition together.
- Use border-gradient wrappers for premium blue feature blocks and dark cards, then place cleaner inner fills inside them so the edge treatment stays crisp.
- Organize the layout in clean stacked zones: a high-impact contrast block, then quieter index or navigation areas, followed by a restrained legal or footer zone.
- Buttons and CTA cards should feel firm and premium, using dark translucent fills, blue-tinted borders, pale-blue copy, and hover states that brighten slightly.
- Typography should remain light and elegant: thin to regular sans-serif weights, generous spacing, and small uppercase utility lines for section numbering or metadata.
- Use subtle abstract blue light fields, large blurred glows, circular traces, or soft overlay washes to add atmosphere without weakening the clean structure.
- Motion should stay calm and premium: masked word reveals, fade-up sections, quiet icon drift, and gentle hover translation are appropriate.
What ships with it
3 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.
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-blue-contrasting-clean is a skill published in the GitHub repository MengTo/Skills (5,919 stars, last pushed 13d ago), licensed MIT. It adds 32 tokens to every session and 839 once invoked, about $0.0002 per session on Opus 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.
