The corner cases your agent won't think of.
The checkout the client can't break.
Blueprints are feature specs with every edge enumerated — the empty cart, the declined card, the expired invite — plus the shadcn components to build them. Your agent pulls only the sections it needs over MCP, so it ships the flow you'd have found in QA, before you quote.
This is where your project lives on Monday morning.
Projects come first. Components and blueprints come with them.
Projects
Private workspaces to plan a whole app. Screens, pinned sections, status, comments, sharing.
Blueprints
Feature specs for whole app types — every screen, every corner case enumerated, every component named. Your agent consumes just the sections it needs over MCP.
Registry
Installable shadcn-spec sections. Add them with the official shadcn CLI or pull them over MCP — the code lands in your repo, yours to keep.
Pick it. Point your agent at it. Ship it.
