Claude Code

Place the file in your project directory. Claude Code will read it automatically when you reference Yumina, or you can paste it directly:

Read yumina-world-spec.md, then create a survival horror world with health, sanity, and hunger tracking.

Cursor

Add the file as a context reference in your Cursor workspace. Then ask:

Using the Yumina world spec, build a dating sim with three heroines and an affinity system.

ChatGPT / Other

Paste the spec contents (or relevant sections) into the conversation, then describe your world.

What the Spec Contains

The downloadable file combines all sections into one document:

1. World schema (top-level structure)
2. Entries & sections (types, keywords, matching, presets)
3. Variables & directives (types, operations, syntax, behavior rules)
4. Rules & reactions (triggers, conditions, actions, system effects)
5. Macros (all placeholders)
6. Custom UI API (rootComponent, useYumina(), components)
7. Audio (tracks, directives, playlists)

The file is ~15KB of pure technical reference — no tutorials, no explanations, just the spec. Optimized for AI consumption.
