Name: Error Handling Patterns
Author: JimmyPaolini

This skill consolidates error handling conventions across the monorepo.

When to Use This Skill

Use when asked to:

Validate inputs or parse API payloads
Handle errors in server functions
Add retry logic or backoff
Fix any usage in catch blocks

Core Rules

Validate at boundaries with Zod
Use unknown in catch blocks and narrow
Avoid swallowed errors
Prefer early returns over deep nesting

Zod Validation at Boundaries

import { z } from "zod";

const Schema = z.object({
  id: z.string().uuid(),
  limit: z.number().int().positive().optional(),
});

const data = Schema.parse(input);

try {
  await doWork();
} catch (error: unknown) {
  if (error instanceof Error) {
    console.error(error.message);
  } else {
    console.error("Unknown error", error);
  }
}

const MAX_RETRIES = 3;
const BASE_DELAY_MS = 500;

for (let attempt = 0; attempt <= MAX_RETRIES; attempt++) {
  try {
    return await fetchData();
  } catch (error: unknown) {
    if (attempt === MAX_RETRIES) throw error;
    await new Promise((resolve) =>
      setTimeout(resolve, BASE_DELAY_MS * Math.pow(2, attempt)),
    );
  }
