SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Fiction projects accumulate characters, settings, factions, and lore across many files, and it is easy to lose track of mentioned-but-undocumented entities or introduce contradictions between entries. This Skill keeps a worldbuilding knowledge base consistent by auto-stubbing new entities and flagging conflicts. ## Core Features & Use Cases - Auto-stub on mention: When a chapter, session log, or entry references a name not yet captured, the agent creates a stub file in the correct folder with backlinks to where it was mentioned. - Contradiction flagging: When a character's faction field conflicts with their narrative actions, or a setting is described two ways, the conflict is surfaced as a story-relevant detail rather than silently fixed. - Graph threading: Characters, factions, settings, themes, and lore are cross-linked so each entry becomes a hub for everywhere it appears. - Use Case: While drafting a chapter that mentions a new tavern and an unknown mercenary group, the agent automatically stubs entries in settings/ and factions/ with backlinks, then warns that the mercenary group's stated allegiance contradicts an existing lore entry. ## Quick Start Ask the agent to review the latest chapter draft, stub any newly mentioned characters or locations, and report any contradictions with existing lore entries.

Frequently Asked Questions about worldbuilding

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I auto-create character entries when writing fiction?▼

Mention a new name in a chapter, session log, or existing entry and the agent stubs a file in the characters folder with backlinks to where it was mentioned. The stub uses the appropriate template so structure stays consistent.

How to check a fictional world for internal consistency?▼

Ask the agent to review entries for contradictions, such as a character whose faction field conflicts with their narrative actions or a setting described two different ways. Conflicts are surfaced as story-shaping details rather than silently corrected.

What folders does the worldbuilding starter pack use?▼

The pack uses five folders: characters for PCs and NPCs, settings for locations and world-rules, themes for recurring narrative concerns, factions for political and social groups, and lore for history, mythology, and magic systems.

Does the worldbuilding skill work without the OpenKnowledge MCP server?▼

No, it requires an agent host with the OpenKnowledge MCP server configured, and it is installed project-local via the ok seed command. The platform open-knowledge skill still governs all markdown read, write, and linking operations.

Can I use this skill for TTRPG campaign stat blocks?▼

No, the skill explicitly excludes TTRPG stat-block fields like xp_awarded, which are reserved for a future TTRPG variant. It focuses on narrative encyclopedia content such as characters, factions, and lore.
