Promo Code Bulk Generator

Purpose

Generates N unique discount codes (e.g., 100 codes for an influencer giveaway, 500 for a partner distribution drop) with a shared prefix and configurable value, usage limit, and validity window. Each code is created as a standalone DiscountCodeBasic discount node so it can be tracked independently in Shopify Admin and revoked individually if leaked. Typical use: handing each code to a different recipient where each redemption must be tied to one person.

Prerequisites

Parameters

Safety

> ⚠️ Step 1 executes one discountCodeBasicCreate mutation per generated code. Once created, codes appear immediately in Shopify Admin and become redeemable at starts_at. Codes cannot be deleted in bulk via the Admin API — they must be removed individually with discountCodeDelete. Run with dry_run: true to confirm the count, prefix, and value before committing. The default is dry_run: true. For high counts (>100), confirm usage_limit matches intent — a single high-limit code is usually preferable to N single-use codes if uniqueness per recipient is not required.

Workflow Steps

Inputs: basicCodeDiscount.title: " bulk generation ", basicCodeDiscount.code: , basicCodeDiscount.startsAt: , basicCodeDiscount.endsAt: , basicCodeDiscount.usageLimit: , basicCodeDiscount.appliesOncePerCustomer: true, basicCodeDiscount.customerGets.value: percent / fixed-amount / free-shipping union per value_type, basicCodeDiscount.customerGets.items.all: true, basicCodeDiscount.customerSelection.all: true

Expected output: codeDiscountNode.id, codeDiscountNode.codeDiscount.codes.edges[0].node.code, userErrors

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Promo Code Bulk Generator            ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):
