Built for agents
Andromeda Pro Brain
PremiumComponents are the pieces. The Brain is the judgment.
69 files your AI agent reads before it builds: the system's rules and inventory, fifteen foundations, a rule file for each of the 45 components, two skills and five tools. Every file name is open on this page. Premium puts the files in your project.
The difference
Where the classic workflow leaks.
A design system made for people loses intent at every handoff. One made for agents is already code, tokens and written rules.
| Classic design system | With the Brain |
|---|---|
Docs written for people, skipped by agents | Rules written for the agent that builds |
Intent lost between the mock-up and the code | No handoff: the system is already code and tokens |
Every new screen drifts a little further off-brand | Every screen is built against the same rules |
Done means it looked right once | Done means it passed the done-gate |
A change means another design-to-code round trip | Change a token and everything built on it follows |
Your agent does the building. You stay in the loop, and you decide what ships.
The design brain
The taste lives in the system, not the prompt.

What comes out
Andromeda Pro Brain69 filesWhat's inside
The 69 files your agent reads first.
Rules written for the machine: when a color may carry meaning, how far a panel may breathe, what every state owes the user. The names are open. What is written inside them ships with Premium.
One file per component, holding the decisions that make it Andromeda Pro instead of generic.

Legacy vs Pro
A step forward from the Andromeda Brain.
The Pro Brain grew out of Andromeda Legacy. It covers more of the system, closes the gaps agents slipped through, and hands the checking to scripts.
| Measure | Legacy Brain | Pro Brain |
|---|---|---|
| Files | 56 | 69 |
| Foundations | 12 | 15 |
| Component rules | 39 | 45 |
| Tools | 1 | 5 |
New foundations: family-shape-law, theming, typography. New component rules: Burst, ChoiceCard, FunnelChart, Nodes, Orb, TopBar.
Three color layers
Raw colors belong to the theme. A component only reads what a color means, and the done-gate fails any component that reaches past that line.
Themes that stay live
Tokens are read when the page runs, not baked in at build, so one component serves light and dark. Canvas and SVG get their own rule.
One type ladder
Small, medium and large controls take 12, 14 and 16px type, with a 12px floor. Your agent stops guessing font sizes.
Checked by scripts, not by eye
Contrast is measured in both themes, and every accent and status color follows one shape law. A retune that hurts readability fails a check before anyone looks.
How it works
Your agent reads it, not you.
Nobody has to learn the system or keep it in their head. The two skills walk your agent through the same four steps on every build.
Start at the index
It reads the system's rules first, then checks the inventory, so it reuses a component before inventing one.
rules.mdINVENTORY.mdOpen what the task needs
Only the foundations and component rules this screen touches, never a guess from generic taste.
layout.mdButton.rules.mdBuild on the tokens
The building skill keeps every value on a token, and a quick color check runs while it works.
building-with-andromedaCheck before it says done
The done-gate runs on the finished screen, then the review skill walks every must rule.

Give your agent the Brain.
One command installs all 69 files in your project, and running it again updates them. Premium also opens the reader, with every rule a click away while you work.
