What problem does it solve? Getting a second opinion on Google Ads campaigns, SEO metadata, or code changes usually means relying on a single AI model's perspective, which can miss platform-specific issues. This Skill launches Google's Gemini CLI as an independent reviewer with native Google ecosystem knowledge, catching problems a single model might overlook. ## Core Features & Use Cases - Review Mode: Produces a structured PASS/FAIL verdict on Google Ads changes, SEO metadata updates, or code diffs, with blocking issues, warnings, and strengths. - Challenge Mode: Runs an adversarial stress test that questions assumptions, cites Google policy and auction mechanics, and rates each change as SOUND, RISKY, or RETHINK. - Consult Mode: Answers open strategy questions about Google Ads bidding, SEO best practices, or implementation with an opinionated recommendation. - Cross-Model Analysis: Compares Gemini's findings against a prior Claude review, highlighting overlapping findings, unique catches, and disagreements. - Use Case: After adding 50 broad-match keywords to a Search campaign, ask for a Gemini review to get a pass/fail gate covering match-type risks, budget efficiency, and missing negative keywords before shipping. ## Quick Start Ask the assistant to run a gemini review of your pending Google Ads or SEO changes and report the verdict.
