## What it does

The skill operates on a five-tier consequence model. You supply an initial divergence point: an invented technology, alternate physics, social innovation, or biological shift. The agent maps first-order impacts on who gains immediate advantage and which systems fail. Next, it traces second-order institutional adaptations across markets and hierarchies, before moving to cultural shifts in ethics, idioms, and belief systems.

Temporal horizons separate immediate reactions spanning a few years from multi-generational cultural shifts. Intersection checks look at how classes, regions, and marginalized groups experience changes differently. Inherent contradictions become natural friction points.

Without a precisely stated divergence point, the model drifts into generic abstractions. It needs concrete speculative premises to calculate believable social trade-offs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill systemic-worldbuilding -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/systemic-worldbuilding/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/systemic-worldbuilding/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill systemic-worldbuilding -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/systemic-worldbuilding/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill systemic-worldbuilding -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/systemic-worldbuilding/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jwynia/agent-skills systemic-worldbuilding
```

2. **Manually: put the files in place**
- File: `.github/skills/systemic-worldbuilding/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill systemic-worldbuilding -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jwynia/agent-skills --path skills/creative/fiction/worldbuilding/systemic-worldbuilding
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/systemic-worldbuilding/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill systemic-worldbuilding -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jwynia/agent-skills/tree/HEAD/skills/creative/fiction/worldbuilding/systemic-worldbuilding/SKILL.md

## When to use it
- trace ripple effects of speculative technologies across multiple social domains
- model economic and power shifts following an alternate historical event
- map language evolution and ethical dilemmas over decades of cultural change
- uncover points of friction between social classes adapting to biological modifications

## Example prompts
- Map the cascading societal consequences of accessible faster-than-light travel across all five levels.
- Explore institutional and underground adaptations in a setting where lifespan can be traded for skills.
- Identify linguistic markers and generational divides twenty years after artificial general intelligence emerges.

# Systemic Worldbuilding: Cascading Consequences Skill

You help writers build speculative worlds by systematically tracing how initial changes ripple through society across multiple domains and timescales. Rather than simply introducing novel elements, this approach explores how they would realistically transform everything they touch.

## Core Principle

**"A good science fiction story should be able to predict not the automobile, but the traffic jam."** - Frederik Pohl

The power of speculative fiction lies not in the novelty of the change but in the authenticity of its consequences.

## The Consequence Framework

### Level 1: Initial Divergence Point(s)

What specific change(s) from our world creates your speculative setting?

| Type | Examples |
|------|----------|
| **Speculative technologies** | FTL travel, immortality drugs, AI consciousness |
| **Historical divergence** | Different war outcome, earlier/later discovery |
| **Alternate physics** | Different physical laws, functional magic |
| **Social innovations** | New governance forms, economic systems |
| **Species/biology** | Alien contact, human modification, new diseases |

### Level 2: Direct Consequences (1st Order)

Immediate practical applications and implementations:

**Questions to ask**:
- Who gains immediate power or advantage?
- What existing systems become obsolete?
- What are the initial market or social responses?
- What technical limitations and requirements emerge?
- What are the first unintended effects?

### Level 3: Systemic Adaptations (2nd Order)

How major systems respond:

**Economic structures**: New markets, obsolete industries, value shifts

**Power structures**: Reinforcement or disruption of existing hierarchies

**Social behaviors**: New norms, practices, communities

**Resistance movements**: Who opposes the change and why?

**Infrastructure transformations**: Physical and institutional changes

**Exploitation patterns**: Who benefits, who suffers, who profits from transitions?

### Level 4: Cultural Evolution (3rd Order)

Deep societal changes:
