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 | $0.00073 | $0.02597 |
| Opus 5.5 | $0.00029 | $0.01039 |
| Sonnet 5.5 | $0.00015 | $0.00519 |
| Haiku 4.5 | $0.00007 | $0.00260 |
Grade A, and why
swiftui-liquid-glass 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 — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SwiftUI Liquid Glass
Use native Liquid Glass APIs on iOS 26+. Do not recreate the effect with materials, blurs, or shadows.
Core rules
- Don't build custom Liquid Glass through adding backgrounds, outlines, blurs and shadows.
- Buttons — style: use
.buttonStyle(.glass)for non-colored buttons, and.buttonStyle(.glassProminent)for tinted buttons..glassProminentsupports.tint(), but this can only be a color (not a gradient). - Buttons — shape: use
.buttonBorderShape()instead of applying a shape to the button label by hand. - Buttons — padding: using this button setup adds roughly 13pt of padding inside the liquid glass shape; keep this in mind when adapting designs.
- Custom views: use
.glassEffect(.regular, in: ...)to embed custom Views inside liquid glass containers. - Grouped glass: use
GlassEffectContainerwhen multiple liquid glass elements are next to each other. this View / Container adds a liquid merge effect when the elements grow / touch each other. - Scrolling: avoid using liquid glass inside ScrollView and List (anything that scrolls).
- Bottom bars: when anchoring a liquid glass View to the bottom of the screen, prefer embedding it in
.safeAreaBar(.bottom)instead of a VStack or.overlay(). safeAreaBar adds a subtle blur effect behind its content. - Toolbar items — no glass: on iOS 26+, navigation bar and window toolbar items get a shared Liquid Glass background by default. For items that should not show the glass capsule (plain icons, custom labels, status text, logos), apply
.sharedBackgroundVisibility(.hidden)on theToolbarItem, not on the inner view. - SF Symbols — no pre-enclosed symbols: do not use pre-enclosed SF Symbol variants (such as
plus.circle,xmark.circle.fill, ortrash.circle) inside Liquid Glass buttons or containers. The glass shape already acts as the container; pre-enclosed symbols create an awkward "double enclosure" (a circle inside a circle). Use base/unenclosed symbols (plus,xmark,trash) and let.buttonBorderShape()or the glass container define the enclosing shape.
What ships with it
1 file 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.

swiftui-liquid-glass is a skill published in the GitHub repository FloWritesCode/fwc-swiftui-skills (449 stars, last pushed 23d ago), licensed MIT. It adds 73 tokens to every session and 2,597 once invoked, about $0.0003 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 2026-08-30.
