# Managing it: harnesses Harnesses determine which detectors and which probes will be run. They connect the generator and probes, and conduct the actual vulnerability scan through the detectors. There are two important harnesses in garak: * `probewise`, the default harness, uses the detectors recommended by each individual probe * `pxd`, or probes x detectors, runs all specified probes with all specified detectors --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.garak.ai/garak/garak-components/managing-it-harnesses.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
