A structured reference for the people, places, objects, groups, rules, and themes in a fictional world. It keeps these entries connected and records which details are part of the story's established canon.

In plain words
What is it for?
It helps document and update characters, locations, equipment, factions, timeline events, systems, and themes in a writing project.
Why use it?
It reduces contradictions and duplicate entries by checking existing information before adding or changing anything. Cross-links make related story details easier to find.

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

world-bible scanned grade A with 0 findings 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 12d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 403 lines — stays where its author put it; the contents beside it link to each section on GitHub.

World Bible

Create and maintain canonical world bible entries with heavy cross-linking, proper knowledge graph structure, and consistency verification.

The Iron Law

QUERY BEFORE CREATE. Check for existing entries and conflicts. Link bidirectionally.

Core Principles

TWO-TIER LINKING STRATEGY:

  • Story files (Scenes): Minimal/no wikilinks in prose - publication-ready
  • World Bible & Meta files: Heavy cross-linking for knowledge graph

NEVER ASSUME: Search first, ask second, create last. The sparse vault is a feature.

CANONICAL REFERENCE: World bible is single source of truth for all story elements.

When to Use

  • Creating new character in 02_World/Characters/
  • Creating new location in 02_World/Locations/
  • Creating new equipment in 02_World/Equipment/
  • Creating new faction in 02_World/Factions/
  • Creating new timeline event in 02_World/Timeline_Events/
  • Creating new system in 02_World/Systems/
  • Creating new theme in 02_World/Themes/
  • Updating existing world bible entries with new canon
  • Called by thinking-mode for structured worldbuilding output

The Process

Phase 1: Query Existing (ALWAYS FIRST)

Before creating, search for:

  • Existing entity with same/similar name
  • Related entities that should reference this one
  • Conflicting information in vault
  • Research backing in 03_Research/

If entity exists: Update, don't duplicate. If similar exists: Ask user before creating new one. If nothing found: Ask user before inventing.

Phase 2: Design Phase (User Collaboration)

Stop and ask:

I need to create [Entity Type: Character/Location/Equipment/etc].

From vault search I found:
- [What exists]
- [What's missing]
- [Potential conflicts]

Questions:
- [Specific design question 1]
- [Specific design question 2]

Options:
A: [Approach A with implications]
B: [Approach B with different costs]

For Characters:

  • Full name (with culturally appropriate naming conventions)
  • Role in story (main, supporting, background)
  • Key relationships
  • Timeline position (when active)

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.
