First, introduce a new data object for managing the properties `websiteUrl` and `vcsUrl`:

.SiteInfo.java
[source,java]
----
include::{snippetsPath}/developingPlugins/pluginExtension/groovy/buildSrc/src/main/java/org/myorg/SiteInfo.java[tags=snippet]
----

In the extension, create an instance of the `siteInfo` class and a method to delegate the captured values to the data instance.

// Holds the size value of a tensor list and whether the size is statically
// known (fixed).
struct SizeInfo {
  Value size;
  bool fixed;
};

// Modifies a function's signature to rewrite tensor list arguments to buffers
// and sizes.
void ModifyFunctionSignature(
    func::FuncOp func, Type size_type,
    llvm::SmallDenseMap<Value, SizeInfo>* buffer_to_size,
    llvm::function_ref<std::optional<Type>(int64_t)> arg_to_buffer_type,
