breadcrumb-generator
What the author says it does
When the user wants to add, optimize, or audit breadcrumb navigation. Also use when the user mentions "breadcrumbs," "breadcrumb trail," "breadcrumb nav," "breadcrumb links," "path navigation," "site breadcrumb," "BreadcrumbList schema," "location-based breadcrumb," "attribute-based breadcrumb," "site hierarchy display," "add breadcrumbs," or "breadcrumb SEO." For BreadcrumbList JSON-LD, use schema-markup. For main nav, use navigation-menu-generator.

SkillProof status
This skill is in our test queue. We install every skill in a clean environment, run a trigger battery and score output against a baseline before it earns a catalog page — the full protocol is public. Until then, treat it like any unreviewed dependency: read the SKILL.md and any scripts before installing.
