• The meta file must be in JSON format.

• The meta file must be located in the same directory as the registry file.

• The meta file must have the same name as the registry file, but with a .meta.json extension.

• The meta file must contain the following fields:

• name : The registry name in kebab-case, same as file name without extension.

• title : The name of the registry usually the same as the component name in Pascal case.

• type : always "registry:item" .

• description : IMPORTANT! Describe the registry in detail to help LLM understand what the interface looks like and its purpose. Start with "Integrated [library name]" if using third-party libraries (e.g., Base UI). Focus on visible features (buttons, labels, states) and accessibility. DO NOT list individual Material UI components.

• meta : Additional metadata about the registry
