onlyworlds-link

A tool for finding missing connections between elements in a fictional world, such as characters, places, institutions, and objects. It can work with a world folder stored on disk or with the OnlyWorlds API.

In plain words
What is it for?
Use it to audit connections, find orphaned elements, link selected types such as characters and locations, and add or update relationships in world data.
Why use it?
It helps when world information is scattered or some elements have no links to anything else. It can identify unlinked elements and suggest relationships to review or add.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

onlyworlds-link scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Find and create missing connections between world elements.

Quick Reference

User Says Action
"Connect my elements" Full link audit + suggestions
"Find orphans" Identify unlinked elements
"Add relations between characters" Targeted Relation creation
"Link my institutions to locations" Targeted field linking
"Audit my world's connections" Report link density by type

Instructions

Step 1: Pick the Source

  • World folder (no account needed): the user has an Atlas world folder or any OW-shaped folder on disk. Read world.json + every .json under elements//, keyed on internal id (see knowledge/world-folder.md). Applying suggested links = editing the files in place (preserve every field you didn't change, including atlas_/x_ extensions).
  • API: check .ow/config.json first; if not found, ask user for API-Key and API-Pin.

The analysis (Steps 3+) is identical for both sources.

Step 2: Fetch World Data (API source)

Fetch all narrative element types in parallel:

character, creature, species, family, collective, institution,
location, zone, object, construct, title, ability, trait,
language, law, event, narrative, phenomenon, relation

Skip: map, pin, marker (spatial, not narrative links).

CRITICAL: v2 endpoints (/api/v2/{type}), singular type names, www.onlyworlds.com, exact API-Key/API-Pin headers. v2 lists paginate — follow next_cursor until has_more is false. Link fields come back as flat UUID arrays.

Step 3: Analyze the Web

Build a connection map from existing link fields across all elements:

For each element, check:

  • Which link fields are populated? (e.g., Character.location, Character.species, Character.institutions)
  • Which link fields are empty but could be filled based on description content?
  • Does the element appear in other elements' link fields?

Produce three lists:

Orphans — elements with zero incoming or outgoing links:

| Element | Type | Links Out | Links In | Issue |
|---------|------|-----------|----------|-------|
| The Stale Roll | Object | 0 | 0 | Completely disconnected |
| Deep Drip | Location | 0 | 1 | Only referenced by one Event |

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

onlyworlds-link is a skill published in the GitHub repository OnlyWorlds/toolkit (2 stars, last pushed 1mo ago), licensed MIT. It adds 85 tokens to every session and 1,434 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
