Timers or jumps can still be used,\ but they no longer take on safety tasks.\ A timer only confirms that time has passed, not that an action has occurred.\ And a jump is only safe if its target state is defined and verifiable.\ This separation of "process control" and "safety monitoring" is a central component of Selmo design. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://infosys.selmotech.com/selmo-solution/selmo-solution-en/selmo-how-it-works/selmo-training/chapter-3-the-advanced-standard-functions-in-selmo/3.6-the-safety-concept-in-the-background.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
