As part of this update, a new tool package for building **HELLO\_CUSTOM SoT** has been introduced. This package is dispatched separately from the main Harmony Suite, providing a dedicated and flexible solution for custom SoT generation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
