✅ Vale is built in
Mintlify ships two CI checks: one for broken links, one for prose. The prose one is Vale.
Nothing to install, no workflow to copy. Flip on the Grammar linter add-on and it runs on your pull requests—as a Warning that notes what it found, or as Blocking when the prose has to be right before the merge.
Bring a .vale.ini and
they use it, or take their default and start with a style already tuned for MDX.
