All changes and additions seems to be fine. General comments:

• Why the change on convention from _id to index? Because to be similar to react?
• I like the change from acronym to challenge_label
• Should the files _id.spec.js and _id.vue from the tools page be removed? Same for community?

All seems correct

I think that, even in codecov is failing (because of the downgrade of the score of -13.87%), the PR can be accepted.
