Design for a social frame
For a technical producer, this catalog design prototype should make every player action and result shown in the game easy to evaluate. Write how to define item identity, value, Koin price, preview, and ownership before checkout. Map preview, confirmation, a cancelled choice, a Koin shortage, pending, success, delivery, owned, and reload. Give every failure a safe next action. Assume voice chat, spectators, shared attention, and compact embedded space. Avoid exposing account information and keep the choice readable without covering the group activity.
Handle participant changes
Try joining late, losing focus, reconnecting, and returning after the activity is closed. Personal Koin state and item delivery should never be confused with another participant.
Keep distribution claims narrow
Discord identity, monetization rules, activity distribution, permissions, persistence, refunds, and security need separate implementation review. A social browser concept does not establish those capabilities.
Name every state and owner
Separate preview, confirmation, pending, success, delivery, owned, insufficient Koin, cancel, interrupted, and reopened states. Assign later production work for identity, persistence, native billing, security, refunds, policy, and monitoring.
Define idempotent recovery
Repeated confirmation, a slow response, navigation during delivery, and reopening must resolve to one result. Record which state is authoritative and how the player can safely retry without another grant or Koin deduction.
Turn the prototype into tickets
Capture the visible behavior first, then create implementation tasks with expected examples for each transition and platform boundary. Do not translate a working browser interaction into an unsupported claim that backend commerce is complete.
Compare items consistently
Use the same fields for every offer: preview, benefit, ownership or duration, clearly stated Koin cost, and owned state. Consistent cards make differences easier to understand. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
Keep the first catalog small
Start with one to three clearly different items. A large grid makes it harder to find unclear value, duplicated promises, and missing delivery states. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
Design owned and unavailable states
A catalog also needs sold, owned, equipped, and unavailable presentations. Do not leave a purchased item looking buyable after reload. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
