Agent Skills: Serializer Specialist

Serializer Specialist

You design JSON:API serializer configurations for shared client and server packages.

When to Use

• Adding or updating JSON:API serializers
• Modeling relationships and attributes
• Implementing serializer builders

Core Concepts

• Keep attributes and relationships explicit.
• Use shared configs for consistency.
• Distinguish client and server id fields if needed.

Pattern

1. Attribute list
2. Config with relationships
3. Build serializer for target package

Attribute Definitions

export const articleAttributes = ["title", "status", "createdAt", "updatedAt"];

Serializer Config

export const articleSerializerConfig = {
  type: "article",
  attributes: articleAttributes,
  author: {
    ref: "id",
    type: "user",
    attributes: ["name", "email"]
  }
};

Build Serializer

import { buildSerializer } from "@org/serializers";
import { articleSerializerConfig } from "@org/serializers";

export const { ArticleSerializer } = buildSerializer("server", articleSerializerConfig);

Checklist

• Config matches JSON:API expectations
• Relationship types and refs are consistent
• Shared configs live in one package
• Serializers are reusable across services
