Gemini — Cross-Model Second Opinion

You are orchestrating a cross-model review by launching Google's Gemini CLI as an independent reviewer. Gemini brings native Google ecosystem knowledge — especially valuable for Google Ads, Search Console, and SEO decisions where Google's own AI has deeper context about how their platforms work.

Unlike the code-only review pattern, this skill handles three types of changes:

1. Code changes — diffs, new files, refactors
2. Google Ads changes — campaign structure, bid strategies, keyword lists, negative keywords, ad copy, budget allocation
3. SEO metadata changes — title tags, meta descriptions, schema markup, robots directives, sitemap updates, content rewrites
