SOURCE_CLASS_METADATA_KEY

const val SOURCE_CLASS_METADATA_KEY: String

A customMetadata key holding the binary name of the class a tool was generated or built from, paired with SOURCE_METHOD_METADATA_KEY. Both the KSP @Tool processor and ReflectiveTools record it, so a metadata consumer can resolve the source method and read its annotations.
