What it does
iOS Design System is an agent skill from pproenca/dot-skills. Clinic-architecture-aligned iOS design system engineering for SwiftUI (iOS 26 / Swift 6.2) covering token architecture, color/typography/spacing systems, component style libraries, asset governance, and theming. Enforces @Equatable on views and keeps design-system usage compatible with Feature-to-Domain+DesignSystem boundaries. Use when building or refactoring DesignSystem infrastructure for the clinic modular MVVM-C stack.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 56 other files, including reference files and assets (for example `assets/templates/_template.md`, `metadata.json` and `references/_sections.md`).
It sits in Frontend & Design, covering Design systems, iOS development and Typography. It works with iOS, Swift and SwiftUI. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.
When your agent uses it
- Refactoring DesignSystem infrastructure for the clinic modular MVVM-C stack
- Tasks that involve Design systems
- Tasks that involve iOS development
Example prompts
- “/ios-design-system”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
iOS Design System loads about 2.7k tokens when it runs, and up to ~58k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 905 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Clinic-architecture-aligned iOS design system engineering for SwiftUI (iOS 26 / Swift 6.2) covering token architecture, color/typography/spacing systems, component style libraries, asset governance, and theming. Enforces @Equatable on views and keeps design-system usage compatible with Feature-to-Domain+DesignSystem boundaries. Use when building or refactoring DesignSystem infrastructure for the clinic modular MVVM-C stack.
Airbnb iOS Design System Best Practices
Opinionated, strict design system engineering for SwiftUI iOS 26 / Swift 6.2 apps. Contains 50 rules across 8 categories, prioritized by impact. Derived from Airbnb's Design Language System (DLS), Airbnb Swift Style Guide, Apple Human Interface Guidelines, and WWDC sessions. Mandates @Equatable on every view, @Observable for state, and style protocols as the primary component API.
Mandated Architecture Alignment
This skill is designed to work alongside swift-ui-architect. All code examples follow the same non-negotiable constraints:
- Feature modules depend on
Domain+DesignSystem; no directDatadependency @Observablefor mutable UI state,ObservableObject/@Publishednever@Equatablemacro on every view- Style protocols as the primary component styling API (Airbnb DLS pattern)
- Asset catalog as the source of truth for color values
- Local SPM package for design system module boundary
Scope & Relationship to Sibling Skills
This skill is the infrastructure layer — it teaches how to BUILD the design system itself. When loaded alongside sibling skills:
| Sibling Skill | Its Focus | This Skill's Focus |
|---|---|---|
swift-ui-architect | Architecture (modular MVVM-C, route shells, protocol boundaries) | Design system infrastructure (tokens, styles, governance) |
ios-design | Using design primitives (semantic colors, typography) | Engineering the token system that provides those primitives |
ios-ui-refactor | Auditing/fixing visual quality issues | Preventing those issues via governance and automation |
ios-hig | HIG compliance patterns | Asset and component infrastructure that makes compliance easy |
Clinic Architecture Contract (iOS 26 / Swift 6.2)
All guidance in this skill assumes the clinic modular MVVM-C architecture:
- Feature modules import
Domain+DesignSystemonly (neverData, never sibling features) - App target is the convergence point and owns
DependencyContainer, concrete coordinators, and Route Shell wiring Domainstays pure Swift and defines models plus repository,*Coordinating,ErrorRouting, andAppErrorcontractsDataowns SwiftData/network/sync/retry/background I/O and implements Domain protocols- Read/write flow defaults to stale-while-revalidate reads and optimistic queued writes
- ViewModels call repository protocols directly (no default use-case/interactor layer)
When to Apply
Reference these guidelines when:
- Setting up a design system for a new iOS app
- Building token architecture (colors, typography, spacing, sizing)
- Creating reusable component styles (ButtonStyle, LabelStyle, custom DLS protocols)
- Organizing asset catalogs (colors, images, icons)
- Migrating from ad-hoc styles to a governed token system
- Preventing style drift and enforcing consistency via automation
- Building theming infrastructure for whitelabel or multi-brand apps
- Reviewing PRs for ungoverned colors, hardcoded values, or shadow tokens
