# Planning Worldbuilding

> Decomposes a large worldbuilding task into a sequenced plan with concrete steps, target files, verification criteria, and dependency order. Use before building a new civilization, designing a planet, or any task spanning more than 3 files. Triggers on "plan this", "break this down", "how should we approach", "build plan for", or "what is the sequence". Does NOT write content — produces the plan only.

# Planning Worldbuilding

Break large worldbuilding tasks into sequenced, trackable steps.

## When to Use

Any task that will produce more than 3 files.

## Process

1. **Scope:** Map files to create/modify, dependencies, existing constraints
2. **Write Plan:** Save to `meta/plans/YYYY-MM-DD-<topic>.md`
3. **Review:** Present for approval before writing

## Task Design Rules

1. Each task targets one file
2. Tasks have verification criteria
3. Dependencies are explicit
4. Content is concrete (not "flesh out")
5. YAGNI — if not needed for current scope, cut it

## Checkpoint Pattern

For 5+ task plans, insert checkpoints every 3-5 tasks for author review.

## Out of Scope

Does NOT write content (use /writing-science or /writing-worldbuilding).
Does NOT interrogate decisions (use /interrogating-design).
