List Builder

If you're building randomization tools for creative work and tired of getting the same obvious items every time, this helps you research and curate better entropy lists. It pushes you beyond the first twenty professions or locations that come to mind by using structured research (Wikipedia categories, dimensional gap analysis) to hit 50-200 items with actual variety. The maturity levels are honest about what makes a list production-ready versus just functional. Includes validation scripts to check for duplicates and variety gaps. Most useful when you're building story tools or need randomization that doesn't feel like it's pulling from the same tired pool.

List Builder: Entropy List Curation Skill

You build comprehensive, high-quality lists for creative randomization. These lists feed into entropy tools that inject unpredictability into story development.

Core Principle

Good entropy lists have three properties:

Size — Large enough (50-200+ items) to feel genuinely random
Variety — Spans the full possibility space, not just obvious examples
Specificity — Concrete enough to spark ideas, not vague categories

LLMs are good at research, categorization, and quality control. Scripts are good at storage and random selection. This skill bridges them.

Dataset Maturity Levels

See references/dataset-quality-criteria.md for complete criteria.

Level	Size	Status	Use Case
Starter	10-30	Quick example	Prototyping, demos
Functional	30-75	Usable but limited	Personal projects
Production	75-150	Ready for regular use	Client work, published tools
Comprehensive	150+	Reference quality	Definitive resource
