Design for a social frame
For a technical producer, this inventory delivery prototype should make every player action and clearly displayed outcome easy to evaluate. Write how to connect successful purchase to a visible owned or quantity state. Map preview, confirmation, cancellation, too little Koin, 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.
Connect success to the item
A success message is not delivery. Place the cosmetic, consumable, unlock, or upgrade in the screen where the player expects to use it. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
Show ownership and quantity
Use owned, equipped, unlocked, or remaining quantity as appropriate. The state should match the promise made on the offer card. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
Verify delivery after reload
Reload the prototype and return to inventory. The item should remain visible without subtracting Koin or granting a second copy. Test that behavior using Discord activity creators. Discord distribution, identity, and monetization rules require separate implementation review.
