Zod schema validation patterns for API types. An agent skill from LedgerHQ/ledger-live.

  • Tasks that involve Forms and validation
  • SKILL.md covers Structure, Using Schemas in API and Best Practices
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Zod Schemas is an agent skill from LedgerHQ/ledger-live. Zod schema validation patterns for API types

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Forms and validation. It works with Zod. The repository describes itself as: Mono-repository for Ledger Wallet apps and related packages. The licence is MIT.

When your agent uses it

  • Tasks that involve Forms and validation

Example prompts

  • “/zod-schemas”

What it can do on your machine

Read from SKILL.md and the folder at commit 46bd13a. 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 (its code samples are typescript).

    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

Zod Schemas loads about 554 tokens when it runs. Until then it costs about 14 tokens; SKILL.md has 70 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~14
When it runs · the whole SKILL.md, loaded when a task matches
~554

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.

Zod schema validation patterns for API types

Zod Schema Validation

Define types in state-manager/types.ts using Zod schemas for runtime validation.

Structure

  • Define Zod schemas first, then infer TypeScript types
  • Use enums for tag types
  • Export both schemas and inferred types
typescript
// ✅ GOOD - state-manager/types.ts
import { z } from "zod";

// 1. Define tag types as enum
export enum MyDataTags {
  Items = "Items",
  Item = "Item",
}

// 2. Define Zod schemas with validation rules
const ItemSchema = z.object({
  id: z.string().uuid(),
  name: z.string().min(1),
  value: z.number().min(0),
  status: z.enum(["active", "inactive"]),
  createdAt: z.string().datetime(),
});

const ItemResponseSchema = z.object({
  data: ItemSchema,
  meta: z.object({
    timestamp: z.string(),
    version: z.string(),
  }),
});

const ItemListResponseSchema = z.object({
  items: z.array(ItemSchema),
  pagination: z.object({
    nextCursor: z.string().optional(),
    total: z.number(),
  }),
});

// 3. Infer TypeScript types from schemas
export type Item = z.infer<typeof ItemSchema>;
export type ItemResponse = z.infer<typeof ItemResponseSchema>;
export type ItemListResponse = z.infer<typeof ItemListResponseSchema>;

// 4. Define query params as interfaces
export interface GetItemsParams {
  search?: string;
  limit?: number;
  cursor?: string;
}

// 5. Export schemas for runtime validation
export { ItemSchema, ItemResponseSchema, ItemListResponseSchema };

Using Schemas in API

typescript
// state-manager/api.ts
import { ItemListResponseSchema, type ItemListResponse } from "./types";

endpoints: (build) => ({
  getItems: build.query<ItemListResponse, GetItemsParams>({
    query: (params) => ({ url: "items", params }),
    transformResponse: (response: unknown) => {
      // Runtime validation
      return ItemListResponseSchema.parse(response);
    },
  }),
}),

Best Practices

  • Use .min(), .max(), .uuid(), .email() for field validation
  • Use z.enum() for fixed string values
  • Use z.union() for multiple possible types
  • Use .optional() for nullable fields
  • Always infer types with z.infer<typeof Schema>
