# OpenDesigner: extend an existing system

Use this skill when the project already has an OpenDesigner system and someone wants something new. That means `opendesigner/state.json` exists, or a root DESIGN.md made by OpenDesigner. Common requests: a new component, a new theme or platform, a token tweak, zooming deeper into an area, or "why is this blue?". The goal is harmony: new work reuses existing values, and every change is recorded.

The engine is `scripts/engine.py` in this skill when it was installed from a release zip. Otherwise use the sibling opendesigner skill's `scripts/engine.py`. Run it from the project root; state lives in `./opendesigner/`. Stage files, zoom levels, rules, the glossary and the Decision Cards live in `<opendesigner>/references/`. Talk the way `rules.md` says: one idea per message, plain words first, and the person's `profile.voice`.

## 1. Start-up routine (before touching anything)
1. Read, in order:
   - `DESIGN.md` and `PRODUCT.md` (project root). Note each section's zoom line.
   - `opendesigner/state.json` (`profile.voice`, `zoom`, answers, `locks`, hooks).
   - `opendesigner/decisions.md` (newest entries last).
   - `opendesigner/tokens/`.
   - `git log --oneline -15 -- opendesigner/ DESIGN.md`, if the project uses git.
2. If `DESIGN.md.hand-edited` exists, someone edited the generated file by hand. Offer to turn each edit into a decision.
