 - Name tests freely; use `@Test("Display Name")` to set the navigator title.
 - `#expect` is the primary assertion; pass a boolean expression to assert truthy outcomes.
 - Async/throwing tests are supported via `async`/`throws` on the test function.
-- Works alongside XCTest in the same project.

 # Commit Messages
 
-Use this skill to generate clear, conventional commit messages that explain the "why" not just the "what". Follow this guide when writing commit messages or helping users structure their commits.
-
-## When to Use
-
-- User asks for help writing a commit message
-- User wants to understand conventional commit format
-- User needs to split a large commit into smaller ones
-- User asks about commit best practices
-
-## Philosophy
-
-- **Why > What** - The diff shows what changed; the message explains why
-- **Atomic commits** - One logical change per commit
-- **Future readers** - Write for someone debugging at 2am in 6 months
-- **Searchable** - Make it easy to find with `git log --grep`
+Generate clear, conventional commit messages that explain the "why" not just the "what".

-## When to Use Each Guide
+## Inline Example: Schema-First Pattern
 
-### Schemas
+```typescript
+import { z } from "zod";
 
-Use [schemas.md](references/schemas.md) when you need:
+// 1. Define schema at trust boundary
+const UserSchema = z.object({
+  id: z.string().brand<"UserId">(),
+  email: z.string().email(),
+  role: z.enum(["admin", "member"]),

-- Decision framework: when schema is required vs optional
-- Trust boundary identification
-- Test data factory patterns with schema validation
-- Examples of schema usage (API responses, business validation)
+// 2. Derive type from schema
+type User = z.infer<typeof UserSchema>;
 
-### Types and Interfaces
-
-Use [types-interfaces.md](references/types-interfaces.md) when you need:
-
-- Type vs interface guidance
-- The any vs unknown decision
-- Type assertion best practices
-- Strict mode configuration
-- tsconfig.json settings
-
-### Immutability
-
-Use [immutability.md](references/immutability.md) when you need:
-
-- Immutability patterns (spread operators)
-- Readonly modifiers
-- Forbidden array methods reference
-- Options objects vs positional parameters
-- Boolean parameter anti-patterns
-- Result types for error handling
-- Early return patterns
-
-### Utilities
-
-Use [utilities.md](references/utilities.md) when you need:
-
-- Branded types for domain concepts
-- Built-in utility types (Pick, Omit, Partial, etc.)
-- Custom utility types
-- Code smell reference tables
-
-### Patterns
-
-Use [patterns.md](references/patterns.md) when you need:
-
-- Schema-first examples at trust boundaries
-- Internal type examples without schemas
-- Schema with test factory patterns
-- Result type for error handling
-- Branded types for domain safety
-- Immutable array operations
-- Options object pattern
+// 3. Validate at boundary, trust internally
+function parseUser(raw: unknown): User {
+  return UserSchema.parse(raw);
+}

-## When to Use Each Guide
+## Canonical Feature Module
 
-### Project Structure
-
-Use [project-structure.md](./references/project-structure.md) when you need:
-
-- Directory organization (app, features, components)
-- Feature module structure
-- Import architecture (unidirectional flow)
-- ESLint boundary enforcement
-- File naming conventions
-
-### Component Patterns
-
-Use [component-patterns.md](./references/component-patterns.md) when you need:
-
-- Colocation principles
-- Composition over props patterns
-- Wrapping third-party components
-- Avoiding nested render functions
-
-### Compound Components
-
-Use [compound-components.md](./references/compound-components.md) when you need:
-
-- Multi-part components (Card, Accordion, etc.)
-- Flexible composition patterns
-- Semantic component structure
-
-### State Management
-
-Use [state-management.md](./references/state-management.md) when you need:
-
-- State category decisions (component, application, server cache)
-- useState vs useReducer guidance
-- Server cache with React Query
-- State placement guidelines
-
-### API Layer
-
-Use [api-layer.md](./references/api-layer.md) when you need:
-
-- API client configuration
-- Request structure (schema, fetcher, hook)
-- Error handling (interceptors, boundaries)
-- Security patterns (auth, sanitization, authorization)
-
-### Performance
-
-Use [performance.md](./references/performance.md) when you need:

-- Alternatives to useEffect
-
-### Testing Strategy

+src/features/auth/
+├── components/
+│   └── LoginForm.tsx      # Feature-scoped component
+├── hooks/

+│   └── auth.ts            # Schema → fetcher → hook
+└── index.ts               # Public API (barrel export)
+```
 
-- Testing pyramid (prioritize integration over unit)
-- What to test at each level (unit, integration, E2E)
-- Testing Library principles (query by accessible names)
+```tsx
+// src/features/auth/api/auth.ts — schema-first API pattern
