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 | $0.00042 | $0.00641 |
| Opus 5 | $0.00021 | $0.00320 |
| Sonnet 5 | $0.00008 | $0.00128 |
| Haiku 4.5 | $0.00004 | $0.00064 |
Grade A, and why
macos-liquid-glass-designer 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 12d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
macOS Liquid Glass Designer
Modernize macOS SwiftUI UI by using standard app structure and system materials first; add custom glass only for app-specific surfaces.
Workflow
- Inspect the scene/root view and identify the pattern: split view, tab, sheet, toolbar, inspector, custom floating controls.
- Remove custom opaque backgrounds, scrims, and toolbar/sheet fills that fight system material unless intentionally required.
- Update standard SwiftUI structure and controls first.
- Add
glassEffectonly where standard controls do not cover the design. - Validate grouping, transitions, icon treatment, pointer/keyboard usability, and foreground activation. Use
macos-runtime-debuggerfor SwiftPM GUI apps.
Rules
- Prefer
NavigationSplitView; let sidebars use system Liquid Glass material. - Use
backgroundExtensionEffectfor hero/media that should extend beyond safe area near floating chrome. - Keep inspectors visually lighter than or equal to the content they inspect.
- Keep
TabViewfor persistent top-level sections; do not force iPhone tab/search patterns onto macOS. - Remove old
presentationBackgroundimitation layers when the system sheet material is enough. - Put hierarchy-wide search on
NavigationSplitView; usesearchToolbarBehaviorfor compact secondary search. - Assume toolbar items live on floating glass; use
ToolbarSpacer,sharedBackgroundVisibility, andbadgeinstead of custom chrome. - Tint icons/glass only for semantic meaning.
- Prefer standard controls and system glass/prominent button styles before custom translucent buttons.
- Use
controlSize,buttonBorderShape, sliderstep/ticks/neutralValue, andLabelbefore custom controls. - Use concentric rectangle/container corner configuration for custom shapes that must align with sheet/card/window corners.
Custom Glass
glassEffectdefaults to a capsule-like shape and vibrant text; pass an explicit shape when needed.- Use
.interactive()for custom controls/containers with interactive elements. - Put nearby custom glass in one
GlassEffectContainer; separate containers cannot sample each other correctly. - Use
glassEffectIDwith a local@Namespacefor collapsed/expanded morphing with stable identity.
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.

macos-liquid-glass-designer is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 15d ago), licensed MIT. It adds 42 tokens to every session and 641 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.
