vale-config deleted "settings in a glob section only apply to files matching that glob" — the single most common Vale misconfiguration. Nothing in either lint skill told an agent that BasedOnStyles under `[*.md]` governs `.md` only; the nearest survivor was a parenthetical in a reference file the skill opens only for the full field listing. Restored to the always-loaded body, at the point of use. vale-config also never mentioned `[formats]` or MDX at all, leaving the whole decision in that same reference file. Verified against Vale 3.15.2: an unmapped `.mdx` covered by one of your globs is `E100 [lintMDX]`, exit 2, and every other file in that invocation produces no output whatsoever. Because the failure is invocation-wide rather than per-file, it belongs in the Gotchas. The crash requires a glob that actually covers `.mdx` — under `[*.md]` the file is skipped and nothing fails — so the Gotcha states that condition rather than the broader claim that any `.mdx` in the tree kills the run. The mapping-versus-mdx2vast attribution disagreed across the two skills: vale-run said `[formats] mdx = md` is "what vale-config recommends" while vale-config presented it as a bare either/or. Fixed on the source side by having vale-config actually recommend it and say why, which makes vale-run's existing sentence true with no edit to vale-run. Refs: #117
vale-config
Install and configure Vale, the prose/style linter — .vale.ini, StylesPath, built-in/third-party/custom styles, and activation via BasedOnStyles.
What it does
Covers the setup side of Vale: getting a project from no config to a working .vale.ini where vale sync runs clean and every declared style is actually activated for the right files. Does not run Vale or interpret its output — see vale-run for that.
Usage
/vale-config
Describe what you want configured: initial setup, adding a third-party style package, or a custom rule. The skill covers install, StylesPath layout, .vale.ini structure, and BasedOnStyles activation.
