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 | $0.00080 | $0.05444 |
| Opus 5 | $0.00040 | $0.02722 |
| Sonnet 5 | $0.00016 | $0.01089 |
| Haiku 4.5 | $0.00008 | $0.00544 |
Grade A, and why
app-icon-generator 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 11d 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 — 388 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Icon Generator
Generate an app icon programmatically with a CoreGraphics Swift script, resize it to every required size, and install it into the Xcode asset catalog — with appearance variants (light/dark/tinted).
Read first — the Liquid Glass era (iOS 26 / macOS 26)
Apple icon standards verified as of July 2026 — Icon Composer, Xcode 26, macOS Tahoe 26.4+. This guidance is static (the skill does no per-run web lookup); if that date is well in the past or the OS has moved on, re-verify against the HIG · App icons before trusting the specifics below.
Apple's shippable icon format changed. On iOS 26 / macOS 26 the modern app icon is a layered, light-responsive Liquid Glass icon authored in Icon Composer (free; ships with Xcode 26, needs macOS Tahoe 26.4+). You supply flat artwork in up to four depth groups (background → foreground); the system renders the glass — specular highlights, refraction, translucency, shadows — and masks the rounded-rect shape. One .icon file adapts across iPhone, iPad, Mac, and Apple Watch and across Default / Dark / Mono (tinted) appearances.
So this skill does NOT produce the final iOS 26 icon. Icon Composer is GUI-first; no script can author a true layered .icon. Its two honest roles are:
- Placeholder — a fast flat 1024 PNG so early builds, TestFlight, and screenshots feel real before you invest in the real icon.
- Layered source art — flat background / midground / foreground PNGs (or SVGs), effect-free, ready to drag into Icon Composer, where you assemble depth and export the
.icon.
What changed vs. the classic flow:
- Do not bake in lighting. No pre-painted specular highlights, drop shadows, or gradients-used-as-lighting — the system owns those now, and baking them in double-exposes against the system glass. (The
drawShine/drawShadowblocks below are legacy-only, off by default for iOS 26+ targets.) - Do not round the corners. Icon Composer / the system apply the shape mask — fill a full square canvas.
- SVG for shapes, PNG for effects — vector where you can, raster only where you must.
- Provide appearance variants — light (default), dark, and tinted/mono. A single flat PNG only fills the light slot and won't adapt on iOS 18+.
What ships with it
2 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.

app-icon-generator is a skill published in the GitHub repository rshankras/claude-code-apple-skills (719 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 5,444 once invoked, about $0.0004 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.
