Insulated or bare copper for ground pigtail?

I'm currently replacing all the outlets in my 50+ year home. Virtually all have the ground wire attached to the wire clamp screw and nowhere else. I'm updating this to have a dedicated ground screw and pigtail situation with the ground wires, a wire to the ground screw on the metal box, and a wire to the ground screw on the outlet. My question is do I have to completely strip the wire or can I leave it as insulated green between the connections? It comes from the NM wire as bare copper so I assume completely stripping (which is what I've been doing) it is not wrong, but it would be easier to just have to strip the ends if that's allowed.

Either bare or green is allowed. No other colors are allowed.
