Write and test the rules for a customer loyalty program
Define earning, redemption and exception rules before building a custom rewards app.
What you’ll produce
A loyalty-program specification, sample customer journeys and a prototype tested with fictional accounts.
Inputs & connections
- Reward economics, eligible purchases, expiration policy and redemption rules
- Existing checkout process, staff roles and examples of returns or mistaken stamps
Begin with a local prototype and synthetic customer records. Wallet passes, checkout integrations and customer messaging each require separate service setup.
Your starting prompt
Replace the bracketed fields. This is our suggested prompt, not a quote from the source.
Help specify a loyalty program for [business] using [approved rules]. Define how customers earn and redeem rewards, how refunds affect balances, who can correct a mistake and how every balance change is recorded. Calculate the reward cost from the provided margins without inventing missing costs. Design minimal data fields and staff permissions. Create test cases for duplicate purchases, repeat scans, refunds, lost access and concurrent redemptions. Build only a prototype with fictional accounts. Treat Apple Wallet or point-of-sale support as integration requirements to validate, not completed features. Return the specification, test results and unresolved decisions before any production launch.
How to run it
- 01
Agree on reward rules and calculate their cost using real product margins.
- 02
Map the checkout and redemption steps for customers and staff.
- 03
Create a prototype using fictional accounts and a transaction history.
- 04
Test duplicate scans, mistaken credits, returns and simultaneous redemptions.
- 05
Have the owner approve the rules and validate payment or wallet integrations before handling real customers.
Review before you act
Confirm reward economics, permissions, duplicate protection, balance history and a workable correction process.
Limitations & success checks
- A working demo does not establish that wallet or checkout integrations are production-ready.
- Rewards can create unexpected costs if stacking, refunds or repeat redemptions have not been specified.
Measure: Test cases passed, incorrect balances found, time to redeem and reward cost per eligible purchase.

The author reports building a coffee-shop loyalty app using Google Antigravity and Claude Opus 4.5, including Apple Wallet and gifting features. These integrations are practitioner claims, not independently tested capabilities. This guide proposes a specification and prototype. The prompt, setup and checks are original editorial additions; the directory has not reproduced the deployment.
