Documentation

README

Excerpt

Worldbuilding pack — how to work here

This project is a fiction encyclopedia. The graph is the product: characters, settings, themes, factions, and lore that link to each other. The agent's main jobs are auto-stubbing new entities as they're mentioned and flagging contradictions. This skill holds those behaviors so templates and folder descriptions stay clean.

This skill is pack guidance. The platform /open-knowledge skill (read/write/preview/linking/grounding rules) still governs every markdown operation — this layers the worldbuilding conventions on top.
