The mistakes that quietly hurt your docs.
Malformed links and images
Empty destinations, missing anchor text, unencoded spaces, and images with no alt text. This checks markup structure, not whether remote URLs return 200.
Heading hierarchy
Missing H1, multiple H1s, level skips (H1 → H3) — search engines and screen readers expect sequential structure.
Front-matter integrity
YAML, TOML, or JSON front-matter that opens but never closes is a common cause of broken static-site builds. We catch delimiter problems before deploy.
Unclosed code fences
A ``` you forgot to close swallows the rest of the document. We tell you exactly which line opened it.
Table column mismatches
When the separator row has fewer columns than the header, the renderer silently misaligns rows. We flag the mismatch.
SEO-adjacent warnings
Missing image alt text, links with no anchor text, documents without an H1. The things Google notices, even if your renderer doesn't complain.
