Founders generally worry too much about this, but if you're unsure, you could try to hold back some aspect of the specific implementation of an idea.

A more general answer might be useful: VCs are just one of the groups you might talk to, and most of the time you're not onto something big, and the most valuable thing for your time is to share the idea and hear the truth. Telling people your idea also lets YOU refine it. Working a bubble usually ends up meaning you work longer on the idea before you finally unveil it, and start to refine it.

The refining, the iteration and the hustle are what matter.

Good luck!
