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 | $0.00095 | $0.01122 |
| Opus 5.5 | $0.00038 | $0.00449 |
| Sonnet 5.5 | $0.00019 | $0.00224 |
| Haiku 4.5 | $0.00010 | $0.00112 |
Grade A, and why
apple-platform-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.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Platform Design
Apple apps feel native because they respect platform conventions, use system materials and motion, and get the small physical details right. Copying a web or Android design onto iOS/macOS reads as foreign instantly.

Core HIG principles
- Hierarchy, harmony, consistency — content-first (defer to content), clear focus, familiar patterns.
- Respect system conventions: back gestures, share sheet, context menus, safe areas. Don't reinvent them. Which conventions apply is per-platform — text scaling is one that differs, see the iOS and macOS sections below.
Liquid Glass (iOS 26 / macOS Tahoe)
- Translucent, layered materials convey hierarchy — the navigation layer floats in glass over content. Use it for chrome (tab bars, toolbars, sheets), not everywhere.
- Capsule controls; content shows through with adaptive tint. Verify contrast/legibility over busy content (add a scrim if needed); adoption should be tasteful, not a gimmick.
Fluid-interface principles (WWDC "Designing Fluid Interfaces")
- Response: kill latency — respond to touch instantly.
- Direct manipulation: 1:1 finger tracking during gestures.
- Interruptibility (most important): every animation is redirectable mid-flight.
- Behavior over animation: use springs; hand off gesture velocity into the release; project momentum to where the gesture is going.
- Rubber-banding at boundaries; symmetric, anchored motion paths.
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.

apple-platform-design is a skill published in the GitHub repository HalidSaglam/saglitzdesign-mcp (6 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 1,122 once invoked, about $0.0004 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.
Other skills, from other repositories
platform-conventions
Design to iOS and Android conventions — what each OS mandates, where they diverge, and when to unify. Use when shipping native apps. For breakpoint adaptation use responsive-design; for matching competitor patterns use jakobs-law (interaction-design).
logo-creator
Create logos using AI image generation. Discuss style/ratio, generate variations, iterate with user feedback, crop, remove background, and export as SVG. Use when user wants to create a logo, icon, favicon, brand mark, mascot, emblem, or design a logo.
omh-apple-design
This is an OMH apple-design workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
conversational-ux
Design voice and conversational interfaces — dialog flows, error recovery, and persona. Use when the interface speaks and listens rather than being tapped. For graphical input collection, use form-design.
design-system-governance
Define how the system evolves — contribution model, versioning, deprecation, and change management. Use when multiple teams contribute. For driving uptake use design-system-adoption (designer-toolkit); for design file history use version-control-strategy (design-ops).
design-negotiation
Advocate for design quality, scope, and timeline with partners and leadership using evidence and shared goals. Use in the conversation itself. For the commercial vocabulary behind it, use business-design (ux-strategy).
