🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Apply array @length to the array, not its elements.
If a primitive string array has @length(2), this call passes the attribute to makeScalarSchema before applyCardinality creates the array. The resulting schema checks each string’s length. It rejects ['a', 'b'] and accepts ['ab'], contrary to the array constraint. Separate array-level attributes from element attributes, then apply the array constraint after creating the array schema.

@sanny-io, the results confirm the distinction I missed. getAllFieldAttributes combines the consuming field’s attributes with the primitive type’s this attributes. The ORM Zod factory also calls addListValidation, but the schema factory in this thread does not.
My original quick-fix instruction was incomplete. Applying every combined @length to the array would also apply a this String constraint to the array. The fix needs to preserve attribute provenance before it can apply each constraint to the correct schema. I’ll keep the finding open.

@sanny-io, I checked the missing detail: the built-in @length does not have @@@once. My earlier concern about the two @length declarations was unfounded. I have not run the example, but the declaration permits @length on both strings and lists.
Here is the simple distinction:
datasource db {
provider = 'postgresql'
url = env('DATABASE_URL')
}
model Post {
id Int `@id`
tags Tag[] `@length`(2, 3) // Number of array items
}
type Tag with String {
this String `@length`(1, 10) // Length of each string
}With the schema generated from that file, this is the intended behavior:
import { createSchemaFactory } from '`@zenstackhq/zod`';
import { schema } from './schema';
const postSchema = createSchemaFactory(schema).makeModelSchema('Post');
postSchema.safeParse({ id: 1, tags: ['a', 'b'] }).success; // expected: true
postSchema.safeParse({ id: 1, tags: ['ab'] }).success; // expected: falseThe current factory passes the generated tags attributes to the string schema before it creates the array. It can therefore reject ['a', 'b'] because each string is shorter than two characters, and accept ['ab'] despite the array having only one item. The fix needs to apply Tag.this attributes to each string and Post.tags array attributes to the array.

Learning: In `packages/sdk/src/ts-schema-generator.ts`, `getAllFieldAttributes` inlines a primitive TypeDef's `this` attributes into a consuming model field's generated attributes. In `packages/zod/src/factory.ts`, `makeTypeSchema` separately applies the TypeDef's `this` attributes; validation attributes declared only on the consuming field must also be considered when building its Zod schema.

@ymc9 can you advise on what should be done here, if anything? All attributes are inlined into the consuming field. From that perspective, this behavior makes sense, even if unintuitive. Should @length be handled specially?
There was a problem hiding this comment.
Hey @sanny-io , I think the intended behavior shown by @coderabbitai makes sense. The attributes scoped to the primitive typedef should be only applied to its immediate value type (Tag here) instead of extended to the array.
I haven't thought deeply about this, but if we generate zod schema for each type def, is the problem just solved?
There was a problem hiding this comment.
@ymc9, yes—building a Zod schema for each typedef solves the element-validation part. The consuming field must then apply its own constraints to the array.
For the example above, the resulting composition should be:
const tagSchema = z.string().min(1).max(10);
const tagsSchema = z.array(tagSchema).min(2).max(3);makeTypeSchema('Tag') already builds the typedef schema from its this attributes and typedef-level validation. We can reuse that schema as the array element schema.
However, composition alone does not solve the attribute-scope problem. As the retrieved learning confirms, schema generation already combines the consuming field’s attributes with the typedef’s this attributes. The factory cannot reliably distinguish the two @length declarations from that combined list.
The implementation therefore needs to:
- Preserve which attributes belong to the typedef and which belong to the consuming field.
- Build the element schema from the typedef’s attributes.
- Wrap the element schema in an array.
- Apply the consuming field’s array constraints to that array.
This does not require generating separate Zod source files. Runtime composition through makeTypeSchema is sufficient once the attribute scopes remain distinguishable.
Thanks for clarifying the intended scope.

Learning: In zenstackhq/zenstack primitive typedef validation, attributes declared on a primitive typedef apply only to its immediate value type. For example, in `type Tag with String`, `this String length(1, 10)` constrains each string when a consuming model field uses `Tag[]`; it must not constrain the array. A consuming array field's own `length` constrains the array cardinality. Zod schema composition in `packages/zod/src/factory.ts` must preserve this distinction even though `packages/sdk/src/ts-schema-generator.ts` inlines typedef attributes into consuming field metadata.

Learning: In `packages/sdk/src/ts-schema-generator.ts`, `getAllFieldAttributes` inlines a primitive TypeDef's `this` attributes into a consuming model field's generated attributes. In `packages/zod/src/factory.ts`, `makeTypeSchema` separately applies the TypeDef's `this` attributes; validation attributes declared only on the consuming field must also be considered when building its Zod schema.

Each test fails on the current head and should pass once the corresponding finding is fixed: scalar where-filters, SQLite JSON encoding, numeric defaults, atomic update ops, consuming-field attributes, WhereInput types, nested primitive typedefs, and PostgreSQL array casts.

Hi @sanny-io , thanks for your patience waiting for my review 😄. The changes are overall looking good. I've left some comments and replied to the coderabbit's one.
Claude code also identified a couple of failures and summarized them into a new test file to reproduce. Could you take a look when you have time? The test file can be deleted (or incorporated into other existing test suite files).
| // typedef | ||
| const typedefDef = this.schema.getTypeDef(type); | ||
| if (typedefDef) { | ||
| return this.applyCardinality(this.makeTypeSchema(type as GetTypeDefs<Schema>, def.attributes), def); |

Hey @sanny-io , I think the intended behavior shown by @coderabbitai makes sense. The attributes scoped to the primitive typedef should be only applied to its immediate value type (Tag here) instead of extended to the array.
I haven't thought deeply about this, but if we generate zod schema for each type def, is the problem just solved?
