What is variable-rewards?

A generator for randomized in-app rewards such as daily spins, mystery boxes, bonus points, and reward wheels. It also accounts for limits and probability disclosure.

Use it to create daily bonuses, random reward systems, mystery boxes, or other gamification features in a Swift app.

It provides a structured way to add surprise-based engagement while setting boundaries around frequency and fairness. The rewards described are non-paid mechanics.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.03350
Opus 5.5	$0.00018	$0.01340
Sonnet 5.5	$0.00009	$0.00670
Haiku 4.5	$0.00005	$0.00335

Security

Grade A, and why

variable-rewards scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Variable Rewards Generator

Generate a variable reward system — randomized rewards (daily spins, mystery boxes, bonus points) that leverage variable-ratio reinforcement to increase engagement. Implements ethical engagement patterns with daily/weekly caps, transparent probability disclosure, and no pay-to-play mechanics.

When This Skill Activates

Use this skill when the user:

Asks to "add daily rewards" or "daily spin" mechanic
Wants a "reward system" or "random rewards"
Mentions "mystery box" or "loot box" (non-paid)
Asks about "bonus system" or "daily bonus"
Wants "gamification rewards" or "engagement rewards"
Mentions "reward wheel" or "spin to win"
Asks about "variable rewards" or "intermittent reinforcement"

Pre-Generation Checks

1. Project Context Detection

Check Swift version (requires Swift 5.9+)
Check deployment target (iOS 17+ / macOS 14+ for @Observable and SwiftData)
Check for SwiftData availability and existing model container setup
Identify source file locations

2. Conflict Detection

Search for existing reward or points systems:

Glob: **/*Reward*.swift, **/*Points*.swift, **/*DailySpin*.swift, **/*MysteryBox*.swift
Grep: "reward" or "dailySpin" or "mysteryBox" or "rewardPool" or "lootBox"

If existing reward system found:

Ask if user wants to replace or extend it
If extending, generate only the missing components

3. Platform Detection

Determine if generating for iOS or macOS or both (cross-platform). The templates use SwiftUI and are cross-platform by default.

Configuration Questions

Ask user via AskUserQuestion:

Reward types? (multi-select)
- Points (numeric currency the user accumulates)
- Items (unlockable content: themes, stickers, avatars)
- Features (time-limited feature unlocks)
- Badges (collectible achievement badges)
- Mixed (all of the above) -- recommended
Reward mechanism?
- Daily spin (wheel animation, one spin per day)
- Mystery box (card-flip or chest-open, one per day)
- Random bonus (surprise toast notification on qualifying action)
- Multiple (daily spin + random bonus) -- recommended

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
