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 | $0.00037 | $0.02923 |
| Opus 5 | $0.00018 | $0.01461 |
| Sonnet 5 | $0.00007 | $0.00585 |
| Haiku 4.5 | $0.00004 | $0.00292 |
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 9d 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.

Frontend Design System
Philosophy: Every pixel has purpose. Restraint is luxury. User psychology drives decisions. Core Principle: THINK, don't memorize. ASK, don't assume.
🎯 Selective Reading Rule (MANDATORY)
Read REQUIRED files always, OPTIONAL only when needed:
| File | Status | When to Read |
|---|---|---|
| ux-psychology.md | 🔴 REQUIRED | Always read first! |
| color-system.md | ⚪ Optional | Color/palette decisions |
| typography-system.md | ⚪ Optional | Font selection/pairing |
| visual-effects.md | ⚪ Optional | Glassmorphism, shadows, gradients |
| animation-guide.md | ⚪ Optional | Animation needed |
| motion-graphics.md | ⚪ Optional | Lottie, GSAP, 3D |
| decision-trees.md | ⚪ Optional | Context templates |
🔴 ux-psychology.md = ALWAYS READ. Others = only if relevant.
🔧 Runtime Scripts
Execute these for audits (don't read, just run):
| Script | Purpose | Usage |
|---|---|---|
scripts/ux_audit.py |
UX Psychology & Accessibility Audit | python scripts/ux_audit.py <project_path> |
⚠️ CRITICAL: ASK BEFORE ASSUMING (MANDATORY)
STOP! If the user's request is open-ended, DO NOT default to your favorites.
When User Prompt is Vague, ASK:
Color not specified? Ask:
"What color palette do you prefer? (blue/green/orange/neutral/other?)"
Style not specified? Ask:
"What style are you going for? (minimal/bold/retro/futuristic/organic?)"
Layout not specified? Ask:
"Do you have a layout preference? (single column/grid/asymmetric/full-width?)"
⛔ DEFAULT TENDENCIES TO AVOID (ANTI-SAFE HARBOR):
| AI Default Tendency | Why It's Bad | Think Instead |
|---|---|---|
| Bento Grids (Modern Cliché) | Used in every AI design | Why does this content NEED a grid? |
| Hero Split (Left/Right) | Predictable & Boring | How about Massive Typography or Vertical Narrative? |
| Mesh/Aurora Gradients | The "new" lazy background | What's a radical color pairing? |
| Glassmorphism | AI's idea of "premium" | How about solid, high-contrast flat? |
| Deep Cyan / Fintech Blue | Safe harbor from purple ban | Why not Red, Black, or Neon Green? |
| "Orchestrate / Empower" | AI-generated copywriting | How would a human say this? |
| Dark background + neon glow | Overused, "AI look" | What does the BRAND actually need? |
| Rounded everything | Generic/Safe | Where can I use sharp, brutalist edges? |
What ships with it
9 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.

frontend-design is a skill published in the GitHub repository xenitV1/Antigravity-Workflows (130 stars, last pushed 7mo ago), licensed MIT. It adds 37 tokens to every session and 2,923 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.
