Thanks for sharing. I like the format naming for the sketch working files. Apart of putting in the versioning, I also would like to suggest adding in dates as well.

For instance, [Project Name-Feature-v-yymmdd]
A more detailed would be: [Community page-submit post-v02-20180812]

Why? Two reasons:
1. Easier for other team members to identify the latest working file and to do the handoff (in this case, for Skech]. As a newly joined designer, I would be able to tell how ‘old’ are these working files based on the edited date just from a quick glance.

2. Sometime we tend to copy or move files around. Once we copy a file from one place and paste it at another location (backup etc) the last edited date details helps us to easily identify which is the oldest and which is the latest

Thanks!
