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 | $0.00032 | $0.01826 |
| Opus 5 | $0.00016 | $0.00913 |
| Sonnet 5 | $0.00006 | $0.00365 |
| Haiku 4.5 | $0.00003 | $0.00183 |
Grade A, and why
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 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.
This is a copy
94% identical to liquid-glass — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Liquid Glass
Overview
Use this skill to bring a macOS SwiftUI app into the modern macOS design system with the least custom chrome possible. Start with standard app structure, toolbars, search placement, sheets, and controls, then add custom Liquid Glass only where the app needs a distinctive surface.
Prefer system-provided glass and adaptive materials over bespoke blur, opaque backgrounds, or custom toolbar/sidebar skins. Audit existing UI for extra fills, scrims, and clipping before adding more effects.
Workflow
- Read the relevant scene or root view and identify the structural pattern:
NavigationSplitView,TabView, sheet presentation, detail/inspector layout, toolbar, or custom floating controls. - Remove custom backgrounds or darkening layers behind system sheets, sidebars, and toolbars unless the product explicitly needs them. These can obscure Liquid Glass and interfere with the automatic scroll-edge effect.
- Update standard SwiftUI structure and controls first.
- Add custom
glassEffectsurfaces only for app-specific UI that standard controls do not cover. - Validate that glass grouping, transitions, icon treatment, and foreground activation are visually coherent and still usable with pointer and keyboard.
- If the UI change also affects launch behavior for a SwiftPM GUI app, use
build-run-debugso the app runs as a foreground.appbundle rather than as a raw executable.
App Structure
- Prefer
NavigationSplitViewfor hierarchy-driven macOS layouts. Let the sidebar use the system Liquid Glass material instead of painting over it. - For hero artwork or large media adjacent to a floating sidebar, use
backgroundExtensionEffectso the visual can extend beyond the safe area without clipping the subject. - Keep inspectors visually associated with the current selection and avoid giving them a heavier custom background than the content they inspect.
- If the app uses tabs, keep
TabViewfor persistent top-level sections and preserve each tab's local navigation state. - Do not force iPhone-only tab bar minimize/accessory behavior onto a Mac app. On macOS, prefer a conventional top toolbar and native tab/search placement.
- If a sheet already uses
presentationBackgroundpurely to imitate frosted material, consider removing it and letting the system's new material render. - For sheet transitions that should visually originate from a toolbar button, make the presenting item the source of a navigation zoom transition and mark the sheet content as the destination.
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.

liquid-glass is a skill published in the GitHub repository fanfan-de/anybox (57 stars, last pushed 28d ago), licensed MIT. It adds 32 tokens to every session and 1,826 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to liquid-glass, differing in 2 lines, and is treated as a copy.
