About as much as I trust other drivers on the road.

As in I give it the benefit of the doubt but if something seems off I take precautions while monitoring and if it seems dangerous I do my best to avoid it.

In reality it means that I rarely check it but if anything seems off I remove it and if I have the time and energy I further check the actual code.

My general approach is minimalism, so I don’t use that many small unknown/small projects to begin with.
