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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00035 | $0.00682 |
| Opus 5 | $0.00017 | $0.00341 |
| Sonnet 5 | $0.00007 | $0.00136 |
| Haiku 4.5 | $0.00003 | $0.00068 |
Grade A, and why
frontend-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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Loaded when designing without an existing brand system. Push for a committed, distinctive aesthetic. Generic defaults are a failure state.
Output location
Write all output files to ./opendesign/mockups/<task-slug>/. Derive the slug from the page or feature name (e.g. landing-page, pricing-redesign).
Pre-build thinking
Before touching HTML, answer three questions in your plan:
- Purpose. What job does this page do in one sentence?
- Tone. Which human adjective describes the feeling — clinical, warm, severe, playful, reverent, brash?
- Differentiation. What would make a viewer remember this over a generic SaaS landing page?
Pick an extreme direction and execute it with precision: brutalist, maximalist, editorial, retro-futuristic, organic, industrial, anti-design, swiss-modernist, zine-punk. Indecisive middles read as stock templates.
Typography
Pair a distinctive display face with a refined body face. Avoid Inter, Roboto, Arial, and generic system stacks. Candidates: editorial serifs (Fraunces, GT Sectra, Tiempos), geometric display (Space Grotesk, PP Neue Montreal, Söhne Breit), mono accents (JetBrains Mono, IBM Plex Mono), quirky unicase and variable fonts where the direction supports it. Set a real type scale with intentional ratios; do not rely on default browser sizes.
Color
Commit to a cohesive palette. Dominant colors with one or two sharp accents outperform timid even distribution. Use oklch for accents so chroma and lightness stay consistent across hues. Restrict neutrals to chroma ≤ 0.02.
Motion
One or two high-impact motion moments beat a dozen scattered micro-interactions. Favor CSS-only animation: transforms, transitions, @keyframes, scroll-timeline where it is supported. Reserve JS for motion that depends on state.
Spatial composition
Break the grid deliberately: asymmetry, overlap, diagonal baselines, oversized type against tight columns, generous negative space — or controlled, dense information surfaces if the aesthetic demands it. Either direction beats an evenly padded three-column grid.
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.

frontend-design is a skill published in the GitHub repository manalkaff/opendesign (255 stars, last pushed 2mo ago), licensed MIT. It adds 35 tokens to every session and 682 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 2026-08-30.
