Worldbuilding

Overview

Create and manage world elements for a story project. Locations, systems (magic, politics, technology, etc.), factions, and artifacts 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
   • Routes to other locations: travel time in hours and mode (see references/maps-and-routes.md)
   • Pronunciation, if the name is invented or easily misread (pronunciation: "KEL-ah-mar")
5. Before settling an invented name, run story names "{Candidate}" to catch clashes and look-alikes (see references/naming-languages.md)
6. Create it with story add location "{Location Name}" --type "{type}" when the CLI is available (add --region, --population, --controlled-by, and --character as known); it writes worldbuilding/locations/{name-kebab}.md and updates worldbuilding/_index.md. Then fill the body from references/location-template.md
7. Without the CLI, write the file from references/location-template.md to worldbuilding/locations/{name-kebab}.md
8. Without the CLI, update the worldbuilding/_index.md locations table
9. If notable characters are listed, verify those character files exist and add this location's kebab-case identifier to each character file's locations frontmatter list
10. When CLI access is available, run story reindex ., story links ., and story validate .

Maps, Routes, and Travel

Record travel between locations as routes on the location file, not in prose notes, so the CLI can check it:

routes:
  - to: harbor-district
    hours: 1.5
    mode: on foot
  - to: saltmarsh-fort
    hours: 9
    mode: coach

• to is a location id; story links . checks it exists.
• A route is two-way unless the other location declares its own route back (for example, uphill slower than down).
• story continuity . errors when a character appears in two dated scenes at locations joined by a route and the story time between them is shorter than the route's hours.
• story diagram locations prints the route network as a Mermaid map-graph with edges labelled in hours; add --out dist/locations.mmd to save it. Use it to spot unreachable places and implausible shortcuts.

Use the travel speeds table in references/economy-logistics.md to set plausible hours, and references/maps-and-routes.md for the full workflow.

Creating a System

1. Read story.md for genre and themes context
2. Read worldbuilding/_index.md for existing systems
3. Identify the system type and consult references/world-element-types.md for the relevant prompts. For calendars, naming languages, economies, and magic costs, also use references/calendars.md, references/naming-languages.md, and references/economy-logistics.md
4. Build the system through conversation, addressing the key questions for that type
5. Write the file using references/system-template.md
6. Save to worldbuilding/systems/{name-kebab}.md
7. Update worldbuilding/_index.md systems table
8. Cross-reference with characters who interact with the system (e.g., magic-users for a magic system)
9. When CLI access is available, run story reindex ., story links ., and story validate .

Creating A Faction

Use story add faction "{Faction Name}" --type "{family|guild|government|military|religion|company|community|criminal|other}" when the CLI is available. Otherwise create worldbuilding/factions/{name-kebab}.md with frontmatter fields name, type, status, members, locations, and tags.

Cover:

• Purpose and ideology
• Power base, resources, and territory
• Important members
• Conflicts and pressure points

Then:

1. Save to worldbuilding/factions/{name-kebab}.md
2. Update the Factions table in worldbuilding/_index.md
3. If members are listed, verify those character files exist
4. When CLI access is available, run story reindex ., story links ., and story validate .

Creating An Artifact

Use story add artifact "{Artifact Name}" --type "{object|weapon|document|technology|relic|symbol|resource|other}" when the CLI is available. Otherwise create worldbuilding/artifacts/{name-kebab}.md with frontmatter fields name, type, status, owner, location, and tags.

Cover:

• Description and recognition details
• Function, constraints, and costs
• History and prior owners
• Current owner/location state

Then:

1. Save to worldbuilding/artifacts/{name-kebab}.md
2. Update the Artifacts table in worldbuilding/_index.md
3. If an owner or location is listed, verify those files exist and cross-reference back
4. When CLI access is available, run story reindex ., story links ., and story validate .

Updating World Elements

1. Read the existing file
2. Make the requested changes. If a location or faction changes partway through the story (a city falls, a guild disbands), add a progression instead of editing the opening value (see Changes Over the Story)
3. If cross-references changed, update the linked files
4. Update worldbuilding/_index.md if name, type, or status changed
5. When CLI access is available, run story reindex ., story links ., and story validate .

Changes Over the Story

Location and faction files describe the world as the story opens. Record a later change as a progression, so drafting an early chapter does not see what happens in a late one:

progressions:
  - from: chapter-10
    field: status
    value: occupied
  - from: chapter-10
    field: controlled-by
    value: lord-maren

• from is the first chapter where the new value holds. It may be a planned chapter-NN with no file yet
• field is a kebab-case single-value field, existing (status, controlled-by, region) or new (ruler, population-note). List fields (notable-characters, routes, members, locations, tags) cannot change this way
• value is one value. A faction's type and status must stay within their allowed values
• Keep entries in story order, and read the progressions up to the chapter being drafted before describing the place or faction in it
• Artifacts and systems do not take progressions; track an artifact's changes with object-state and scene state-changes (see the revision-continuity skill)

After adding or editing progressions, run story validate . and story links ..

Cross-Referencing

• Locations reference characters via notable-characters in frontmatter
• Characters reference locations via locations in frontmatter
• Factions reference character members and locations
• Artifacts reference an owner character or faction and a current location
• Systems reference practitioners via character tags
• Location routes reference other locations by id
• Invented names across characters, locations, systems, factions, artifacts, and glossary terms may carry a pronunciation; story build --format narration gathers them into a pronunciation guide for audiobook narrators
• When a location is used in a chapter, the chapter's frontmatter locations field links back
• Keep the worldbuilding/_index.md world overview section current as elements are added

CLI Maintenance

Use the Story CLI when it is available. If story is not installed, use bun run story -- from the Story Skills repository checkout or the bundled fallback node ../story-maintenance/scripts/story.js with the same arguments, resolving the path relative to this skill folder. If no CLI is available, perform the registry, backlink, and word-count checks manually.
