Our go-to reference implementation for a task and mesh shader has been this project: https://github.com/zeux/niagara, which is also accompanied by a series of videos showing its development: https://www.youtube.com/playlist?list=PL0JVLUVCkk-l7CWCn3-cdftR0oajugYvd.
These libraries can be used to generate meshlets:
