ALWAYS use Schema.make() for creating instances:
// ✅ GOOD - Use Schema.make()
const user = Schema.make(User)({ name: 'Alice', age: 30 })
// ❌ BAD - Manual construction
const user = { _tag: 'User', name: 'Alice', age: 30 }
ALWAYS use Schema.is() or static .is method:
// ✅ GOOD
if (Standard.is(value)) { ... }
if (Schema.is(Standard)(value)) { ... }
// ❌ BAD - manual _tag check
if (value._tag === 'Standard') { ... }
ALWAYS inline enum values directly in Schema.Enums():
// ✅ GOOD - inline values, use .enums for runtime access
export const Status = Schema.Enums({
active: 'active',
inactive: 'inactive',
})
export type Status = typeof Status.Type
// Runtime: Status.enums.active
// ❌ BAD - separate const object
export const StatusValues = {
active: 'active',
inactive: 'inactive',
} as const
export const Status = Schema.Enums(StatusValues)

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
