Claude-skill-registry decay-upkeep

Building decay and upkeep systems for survival games. Use when implementing timer-based decay, Tool Cupboard patterns (Rust-style protection radius), resource upkeep costs, or server performance management through automatic cleanup. Balances gameplay and server health.

Decay & Upkeep

Timer-based building decay and resource-based upkeep for survival games.

Quick Start

import { DecayManager } from './scripts/decay-manager.js';
import { UpkeepSystem } from './scripts/upkeep-system.js';
import { ToolCupboard } from './scripts/tool-cupboard.js';

// Decay without protection
const decay = new DecayManager({ 
  mode: 'rust',
  decayMultiplier: 1.0 
});
decay.addPiece(piece);
decay.tick(deltaTime); // Called every frame/tick

// Tool Cupboard protection
const tc = new ToolCupboard({
  radius: 30,
  upkeepCost: { wood: 100, stone: 50 }
});
tc.setPosition(position);
tc.depositResources({ wood: 500, stone: 250 });
// Protected pieces won't decay while upkeep is paid

Scripts

```
scripts/decay-manager.js
```
- Tick-based decay, material rates, damage states
```
scripts/upkeep-system.js
```
- Resource drain, calculation, UI data
```
scripts/tool-cupboard.js
```
- Protection radius, authorization, resource storage
```
scripts/cleanup-scheduler.js
```
- Server-side cleanup of abandoned structures

Decay Modes

Rust: Linear decay over 8-24 hours (material dependent), prevented by Tool Cupboard
ARK: Slower decay (days to weeks), tribe-based protection
Minecraft: No decay (creative/survival), optional via mods

Design Philosophy

Decay serves dual purposes in survival games: gameplay balance (prevents infinite hoarding) and server performance (removes abandoned bases). The Tool Cupboard pattern elegantly ties both together—players must actively maintain bases, and inactive players' structures automatically clean up.
