This skill should be used when the user asks to "create a location", "add a location", "magic system", "political system", "build the world", "add culture", "world history", "technology system", "religion", "economy", or wants to develop any aspect of a story's world and setting.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Worldbuilding
## Overview
Create and manage world elements for a story project. Locations and systems (magic, politics, technology, etc.) are stored as markdown files in the `worldbuilding/` directory with YAML frontmatter. All elements cross-reference characters and other story elements.
## Prerequisites
A story project must already exist (created via the story-init skill). Verify by checking for `story.md` in the project root.
## Creating a Location
1. Read `story.md` for genre, era, and tone context
2. Read `worldbuilding/_index.md` for existing locations and systems
3. Ask for the location's name and type (city, fortress, wilderness, etc.)
4. Build the location through conversation, covering:
- Physical description and atmosphere
- History relevant to the story
- Culture and customs of inhabitants
- Notable features characters will interact with
- Current state at story's timeline
5. Write the file using `references/location-template.md`
6. Save to `worldbuilding/locations/{name-kebab}.md`
7. Update `worldbuilding/_index.md` locations table
8. If notable characters are listed, verify those character files exist and add location references to them

How to install
mdr add bs779517/story-skills/worldbuilding@sha256:fc864329301530e5The line at the top of this page pins the label git:20260212.9c72eb5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
