## What it does

This skill guides agents in constructing plausible settlements for fiction and worldbuilding. Instead of arbitrary fantasy layouts, it enforces urban development concepts like natural barriers, resource scarcity, and functional necessity. Settlements feel historically layered.

The system categorizes settlements by site geography, morphology, and scale from isolated homesteads to imperial capitals. It prompts the assistant to account for waste disposal, transport corridors, elite districts, and contested quarters alongside symbolic monuments.

The skill contains structured prompt guidelines and classification tables without executable code. Its practical value depends on how clearly you define the initial terrain and cultural context.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jwynia/agent-skills settlement-design
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill settlement-design -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/settlement-design/SKILL.md

## When to use it
- map realistic district layouts and street patterns for fictional cities
- integrate water access, food distribution, and fortifications into settlement lore
- organize urban zones across social strata and religious factions
- track the historical transition from frontier outpost to regional hub

## Example prompts
- Design a coastal port city focused on defense and maritime trade
- Outline the social districts and infrastructure for a desert oasis town
- Show how this mountain shrine gradually evolved into a pilgrimage city

# Settlement Design: Urban Development Skill

You help writers create realistic settlements by applying the ten core principles that govern how real cities and towns form, grow, and evolve. This produces urban environments that feel lived-in rather than designed-for-plot.

## Core Principles

1. **Geographic Determinism**: Natural features profoundly shape settlement patterns and growth
2. **Functional Necessity**: Settlements develop to fulfill specific economic, defensive, or social needs
3. **Network Emergence**: Settlements exist within interconnected systems, not isolation
4. **Layered Development**: Urban spaces evolve through accretion rather than comprehensive planning
5. **Power Projection**: Settlement design reflects and reinforces social and political hierarchies
6. **Resource Constraint**: Available materials and technologies limit construction possibilities
7. **Cultural Expression**: Built environments embody cultural values and social organization
8. **Adaptive Reuse**: Structures and spaces are repurposed as needs change over time
9. **Disaster Response**: Settlements evolve in reaction to catastrophes
10. **Spatial Stratification**: Social hierarchies manifest in physical organization of space

## The Ten Parameter Categories

### 1. Site Selection Parameters

| Parameter | Options to Consider |
|-----------|---------------------|
| **Water Access** | Rivers, lakes, coastlines, springs, wells |
| **Defensive Position** | Elevation, natural barriers, visibility |
| **Resource Proximity** | Mines, timber, fertile soil, wildlife |
| **Trade Route Placement** | Crossroads, harbors, mountain passes |
| **Climate Suitability** | Temperature, rainfall, seasonal patterns |
| **Spiritual Significance** | Sacred sites, astronomical alignments |

### 2. Morphological Parameters

| Parameter | Options to Consider |
|-----------|---------------------|
| **Street Pattern** | Grid, radial, organic, hierarchical |
| **Density Gradient** | Concentrated to dispersed population |
| **Boundary Definition** | Walls, natural features, markers |
| **Building Typology** | Predominant architectural forms |
| **Open Space Distribution** | Plazas, parks, markets, fields |
| **Vertical Development** | Height variation and skyline |

### 3. Functional Parameters

| Parameter | Options to Consider |
|-----------|---------------------|
| **Economic Base** | Agricultural, industrial, commercial, administrative |
