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, and glossary terms for the world's invented words in glossary/terms/. 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 lists it in 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. Leave the locations table in worldbuilding/_index.md to story reindex ., even without the CLI; never add a row by hand
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 wordcount . --write, and story check .

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. Create it with story add system '{System Name}' --type '{type}' --prevalence '{prevalence}' when the CLI is available (the type and prevalence values are in references/system-template.md); it writes worldbuilding/systems/{name-kebab}.md and lists it in worldbuilding/_index.md. Then fill the body from references/system-template.md
6. Without the CLI, write the file from references/system-template.md to worldbuilding/systems/{name-kebab}.md
7. Leave the systems table in worldbuilding/_index.md to story reindex .; never add a row by hand
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 wordcount . --write, and story check .

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. Leave the Factions table in worldbuilding/_index.md to story reindex .; never add a row by hand
3. If members are listed, verify those character files exist
4. When CLI access is available, run story reindex ., story wordcount . --write, and story check .

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. Leave the Artifacts table in worldbuilding/_index.md to story reindex .; never add a row by hand
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 wordcount . --write, and story check .

Adding A Glossary Term

Record an invented word, title, rank, or concept that the prose must spell and use the same way every time as a glossary term in glossary/terms/.

1. Read glossary/_index.md for the existing terms, then run story names '{Term}' to catch a clash with another name or term
2. Use story add term '{Term}' --category '{person|place|faction|artifact|concept|term|other}' when the CLI is available, with --alias '{Variant}' once for each accepted variant; it writes glossary/terms/{term-kebab}.md and lists it in glossary/_index.md. Otherwise create the file with frontmatter fields term, category, and aliases, and leave the glossary/_index.md table to story reindex .
3. Fill ## Definition (what it means in the story) and ## Usage Notes (spelling, capitalisation, who uses it, and what it never means). Add a pronunciation when the term is invented or easily misread
4. When the term's capitalisation or hyphenation is a house-style decision, record it in style-sheet.md too (see the voice-style skill)
5. When CLI access is available, run story reindex ., story wordcount . --write, and story check .

A glossary for translators belongs to the adaptation skill, which adds a ## Translations section to these term files.

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. Rename an element with story rename (see references/naming-languages.md). Change its type or status in its own file only: the worldbuilding/_index.md tables pick it up at the next story reindex ., so never edit their rows
5. When CLI access is available, run story reindex ., story wordcount . --write, and story check .

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 reindex ., story wordcount . --write, and story check ..

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 the bundled fallback node ../story-maintenance/scripts/story.js with the same arguments. Use node <checkout>/bin/story.js instead only when the user names a Story Skills repository checkout or you are working in one. Write the script as an absolute path (resolve the fallback relative to this skill folder) and run it from the folder you would run story from, so . and other relative paths keep their meaning. Use Node, not Bun or a package script: Bun would load that folder's bunfig.toml (which can run code) and .env, and a package script runs from the checkout's root. If no CLI is available, perform the registry, backlink, and word-count checks manually.

Reference Files

• references/location-template.md - Template for location files
• references/system-template.md - Template for system files
• references/faction-template.md - Template for faction files
• references/artifact-template.md - Template for artifact/object files
• references/world-element-types.md - Detailed prompts for each system type (magic, political, technology, religion, economic, military, social)
• references/maps-and-routes.md - Recording routes, the story diagram locations map-graph, and the continuity travel check
• references/calendars.md - Adding a custom calendar to story.md, dating scenes in it, and recording seasons and moons as a system file

Shared Conventions

Every story skill follows the shared conventions in ../story-maintenance/references/conventions.md, resolved relative to this skill folder. Read it before creating, renaming, or linking story files. If that file is missing because this skill was installed without story-maintenance, the essentials are: kebab-case ids and filenames, YAML frontmatter on every story-project file, _index.md registry tables that story reindex rebuilds (never edit them by hand), bidirectional links between entities, characters for who is on the page and mentions for who is only referred to, status: deceased plus died-in: chapter-{NN} for deaths, and no project-local generator or build scripts (run only the installed or bundled Story CLI).
