可以添加一些recipe吗，比如retool或者search-r1的复现。

如题。
ROLL的封装挺深的，尤其是在agentic这块，想接入业务场景，但不知道从何下手。 我已经看了官方的文档了，但是有几点还是不太明白。比如：
1. tools 是如何传给system prompt的
2. 如何同时使用多个env进行训练呢；

Start by reviewing the official documentation and the agentic training guidance, focusing on how tools reach the system prompt and how multiple environments are configured. The issue names retool and search-r1 as desired recipe examples, but no files, tests, or entry points are identified. Done would require agreed recipes plus clear answers to both integration questions.
