April 2026 - Component Composition
Composition sections across component pages—structured trees that help you and your agents build correct UI.
We've added Composition sections across the component docs so you can see the correct structure at a glance: what wraps what, which subcomponents belong together, and how to avoid invalid nesting.

│ ├── CardTitle

│ └── CardAction
├── CardContent
└── CardFooter
Why we added this
We've found that LLMs and coding agents compose elements more reliably when they can see the full structure: fewer missing wrappers, fewer wrong hierarchies, better matches to the examples.
Bring docs into your agent
You or your LLM can pull the same component documentation, including composition, usage, and examples, into context from the CLI:
Use the JGuang UI Registry URL provided on /systems/jguang-ui#install.
If you're using the JGuang UI/skills, this is done automatically for you.
