Agentic pipeline data prepare

Is there a specification or example of the data preparation for Agentic? There are tips in doc about data preparation for RLVR, but no about Agentic data preparation.
ps: I have currently customized an env and an env manager.

Start by reading the existing RLVR data-preparation documentation and then inspect the customized environment and environment manager mentioned in the issue. Document the corresponding Agentic data-preparation specification or a working example, with enough detail for users to prepare their own data; done means the guidance is available alongside the RLVR tips.
