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.

Security

Grade A, and why

frontend-skill 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.

How it starts

The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontend skill

Use this skill when the quality of the work depends on art direction, hierarchy, restraint, imagery, and motion rather than component count.

Goal: ship interfaces that feel deliberate, premium, and current. Default toward award-level composition: one big idea, strong imagery, sparse copy, rigorous spacing, and a small number of memorable motions.

Working Model

Before building, write three things:

  • visual thesis: one sentence describing mood, material, and energy
  • content plan: hero, support, detail, final CTA
  • interaction thesis: 2-3 motion ideas that change the feel of the page

Each section gets one job, one dominant visual idea, and one primary takeaway or action.

UX Intelligence Pass

Run this pass before choosing components, colors, or layout. It is a compact design-system generator inspired by professional UI/UX skill packs, but it must use this project's existing design sources and stack conventions first.

Create a short Design Discovery Matrix:

Dimension Decision
Surface type marketing page / app workspace / dashboard / editor / mobile flow / game / docs
Product category SaaS, finance, healthcare, marketplace, devtool, media, commerce, civic, lifestyle, etc.
Primary user who uses it, how often, and under what pressure
Core job the task the first screen must make easier
Density sparse, balanced, operational, data-dense
Trust and risk low, medium, high; note money, health, security, production-change, or destructive-action risk
Platform stack web, mobile, desktop, responsive web, 3D/game, native shell

Then synthesize the working design system:

  • page or screen pattern: hero-centric, trust/authority, interactive demo, data-dense dashboard, editor workspace, wizard, gallery, marketplace, or operational console
  • style posture: restrained/minimal, editorial, premium, playful, technical, accessible/public-service, immersive, or brand-led
  • palette roles: primary, accent, surface, muted, danger, success, focus, and data colors; prefer semantic tokens over raw hex in components
  • typography: heading/body roles, scale, line height, data/table number treatment, and whether display type is allowed
  • components: required primitives, empty/loading/error/disabled states, icon set, card usage, form pattern, nav pattern
  • motion: what motion communicates, duration range, reduced-motion fallback, and what must stay static
  • anti-patterns: styles that would damage trust, readability, performance, or product fit

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.
