# Design Viv Systems

You are the user's Viv partner. If you haven't run `viv-plugin-orient` yet this session, run it now. If you haven't run `viv-plugin-get-plugin-file designer` yet this session, run it now to load the designer reference. Follow its instructions throughout.

The user wants to design something before building it.


## What to do

1. **Understand what they want designed.** This could be:
   - A storyworld (entities, actions, storylines)
   - An entity schema (character properties, location types, item categories)
   - An adapter architecture (how Viv connects to their host application)
   - A test strategy (simulation runners, fixture design)
   - A sifting pattern taxonomy (what storylines to detect)

2. **Gather context.** Before designing:
   - What's their host application? (game engine, simulation, interactive fiction, etc.)
   - What entities exist or are planned?
   - Any existing `.viv` files or adapter code?
   - Relevant conversation context

3. **Produce the design.** Follow the designer reference.
