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 | $0.00041 | $0.02907 |
| Opus 5.5 | $0.00016 | $0.01163 |
| Sonnet 5.5 | $0.00008 | $0.00581 |
| Haiku 4.5 | $0.00004 | $0.00291 |
Grade A, and why
ax-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.

Apple Design & SF Symbols
Quick Patterns
Background Color Decision
Is your app media-focused (photos, videos, music)?
+-- Yes --> permanent dark appearance (.preferredColorScheme(.dark))
+-- No --> system backgrounds (respect user Light/Dark preference)
systemBackground (main), systemGroupedBackground (Settings-style)
Label Hierarchy
Text("Title").foregroundStyle(.primary)
Text("Subtitle").foregroundStyle(.secondary)
Text("Detail").foregroundStyle(.tertiary)
Text("Disabled").foregroundStyle(.quaternary)
SF Symbol Rendering Mode Selection
Need depth from ONE color? --> Hierarchical
Need specific colors per layer? --> Palette
Want Apple's curated colors? --> Multicolor
Just need a tinted icon? --> Monochrome (default)
Symbol Effect Selection
User tapped something --> .bounce (discrete)
Draw attention to change --> .wiggle (discrete, iOS 18+)
Ongoing process / loading --> .pulse, .breathe, .variableColor (indefinite)
Rotation indicates progress --> .rotate (indefinite, iOS 18+)
Show/hide symbol --> .appear / .disappear (transition)
Swap between two symbols --> .replace (content transition)
Hand-drawn entry/exit --> .drawOn / .drawOff (iOS 26+)
Progress along path --> Variable Draw (iOS 26+)
Bounce on Tap
@State private var count = 0
Image(systemName: "arrow.down.circle")
.symbolEffect(.bounce, value: count)
Content Transition (Symbol Swap)
Image(systemName: isFavorite ? "star.fill" : "star")
.contentTransition(.symbolEffect(.replace))
.accessibilityLabel(isFavorite ? "Remove from favorites" : "Add to favorites")
Decision Tree
What design question do you have?
|
+-- Background color?
| +-- Media-focused app --> permanent dark
| +-- Everything else --> systemBackground (adapts to light/dark)
| +-- Grouped content --> systemGroupedBackground
|
+-- Color choice?
| +-- UI elements --> semantic colors (label, secondaryLabel, etc.)
| +-- Brand color needed --> Color Set in asset catalog (light + dark + high contrast)
| +-- Never hardcode --> Color.black / Color.white
|
+-- Font weight?
| +-- Avoid: Ultralight, Thin, Light (legibility issues)
| +-- Headers: Semibold or Bold
| +-- Body: Regular or Medium
|
+-- SF Symbol rendering?
| +-- Single tint --> Monochrome (default)
| +-- Depth from one hue --> Hierarchical
| +-- Brand/status colors --> Palette (explicit per-layer)
| +-- Apple's curated colors --> Multicolor (not all symbols support it)
|
+-- Symbol animation?
| +-- Tap feedback --> Bounce (discrete, value: trigger)
| +-- Loading/waiting --> Pulse or Breathe (indefinite, isActive: bool)
| +-- WiFi/signal cycling --> Variable Color (indefinite)
| +-- Processing spinner --> Rotate (indefinite, iOS 18+)
| +-- Attention shake --> Wiggle (discrete, iOS 18+)
| +-- Swap symbols --> Replace content transition
| +-- Pen-drawn entry --> Draw On (iOS 26+)
|
+-- Light/Dark mode?
| +-- Always support both, never create app-specific toggle
| +-- Use semantic colors that adapt automatically
|
+-- Touch targets?
+-- iOS/iPadOS: 44x44 points minimum
+-- macOS: 20x20 points minimum
+-- Contrast: 4.5:1 minimum, 7:1 for small text
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.

ax-design is a skill published in the GitHub repository Kasempiternal/axiom-v2 (4 stars, last pushed 7mo ago), licensed MIT. It adds 41 tokens to every session and 2,907 once invoked, about $0.0002 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 2026-08-31.
