SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill drives a focused discovery conversation that produces or revises books/{name}/docs/world_rules.md, aggressively filtering for world-building rules that actually affect causality and avoiding decorative background details.

Core Features & Use Cases

  • Causality-focused discovery: Extract only rules that constrain what characters can do, decide, or fear, ensuring the plot remains driven by mechanic constraints.
  • Iterative refinement: Run successive discovery rounds to incrementally flesh out or revise world_rules.md and surface open questions.
  • Surgical writes to world_rules.md: Update the target file with concrete rules and append unresolved questions for later rounds.

Quick Start

Provide a focused discovery round to capture the world rules for the target book.

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

FAQPage Schema
How do I write world rules that actually affect plot causality instead of just decorative background?

World rules drive causality when they capture only constraints on what characters can do, decide, or fear. A focused discovery conversation filters decorative worldbuilding, ensuring rules directly drive plot mechanics through validated, concrete commitments.

What is a world_rules.md file and how do I generate it for book authoring?

A world_rules.md file documents causality-relevant constraints for your fictional setting. You generate it through a focused discovery round that validates inputs, asks targeted questions, and updates the file alongside open_questions.md.

How do I run a focused discovery round to establish world-building constraints?

To run a focused discovery round, provide targeted inputs for your book and engage in an iterative question process. This validates your initial concepts, refines world rules, and appends unresolved items to an open_questions.md file for later rounds.

Can I iteratively revise existing world rules without rewriting the entire document?

Yes, you can iteratively revise existing world rules through successive discovery rounds. This process performs surgical writes to world_rules.md, updating specific constraints and appending new open questions without requiring a full document rewrite.

What is the best way to track unresolved world-building questions during a writing workflow?

The best way to track unresolved questions is to append them to an open_questions.md file. As each focused discovery round concludes, new questions about world rules are logged there for later revision and iterative refinement.

Why does my world-building discovery process keep capturing decorative details instead of usable rules?

Discovery processes capture decorative details when they lack a causality filter. By aggressively filtering for rules that constrain character actions and decisions, you ensure the world_rules.md output remains focused on plot-driving mechanics.
