5 SEO and content-planning skills that work in Antigravity and Claude Code. We read each one at a fixed commit (static review, nothing was run) and list only those. None of them crawls your site, reads Search Console or ranks anything: they are instructions for your agent, so the quality of the result depends on the evidence you give it.
You are considering many templated pages and want a go / no-go first

Honest limits we found: the audit and feasibility scores are subjective rubrics, not search-engine metrics; the SEO Fundamentals script matches text rather than parsing HTML; and Programmatic SEO is inconsistent at the 50-64 band. Details are on each page.
Instruction-only skill for diagnosing crawlability, indexation and on-page SEO problems: it asks for scope first, then reports evidence-backed findings with severity and confidence. It does not crawl or connect to any account.
Safety: Markdown-only audit guide; no scripts, no network, no keys, no account access.
