Worldbuilding
This is diagnostic tooling for fiction writers whose settings feel thin or unconvincing. It walks you through seven world states, from backdrop worlds to flat non-human species, and points you toward specific interventions for each. The consequence cascade framework is the core piece: trace any speculative element through direct effects, systemic adaptations, and cultural evolution. It's opinionated about common failures like monocultures and convenient technology. Think of it as a checklist for whether your magic system has actually transformed society or your institutions feel like they evolved rather than got designed last Tuesday. Pairs with other worldbuilding skills for the actual construction work.

Worldbuilding: Diagnostic Skill
Diagnose world-level problems in fictional settings. Identify what's missing or unconvincing and recommend specific interventions.
When to Use This Skill
Use this skill when:
- Setting feels like a painted backdrop
- Technology/magic hasn't transformed society
- Institutions feel designed rather than evolved
- Economy doesn't make sense
- Cultures lack depth
Do NOT use this skill when:
- Story problems are character-focused (use character-arc)
- Plot structure issues (use scene-sequencing)
- Need to generate worlds from scratch (use systemic-worldbuilding)
Core Principle
Worlds fail when they feel designed rather than evolved.
Good worldbuilding creates the perception that the setting has history, internal logic, and processes that operate independently of the plot.
The World States
W1: Backdrop World
Symptoms: Setting exists but has no independent logic Interventions: systemic-worldbuilding (trace consequences)
W2: World Without Consequences
Symptoms: Technology/magic exists but hasn't transformed society Interventions: Consequence Cascade Analysis
