Skill: Analytics Verifier #30

What

Write a browser skill that verifies analytics tracking is working correctly by browsing real pages and checking that events fire. The existing analytics-tracking text skill knows what to implement — this skill verifies the implementation.

Domain knowledge: .agents/skills/analytics-tracking/ (GA4 implementation, GTM setup, event library)

How to build this

1. Set up hanzi-browse locally
2. Read .agents/skills/analytics-tracking/SKILL.md and its reference files
3. Use hanzi-browse to verify tracking on 5+ real sites. Navigate pages, click CTAs, submit forms — check that GA4/GTM events fire via network tab or dataLayer inspection
4. Write server/skills/analytics-verifier/SKILL.md

What the skill needs to cover:

• Open page, inspect for GA4/GTM presence
• Click through key flows, verify events fire (page_view, custom events, conversions)
• Check dataLayer for correct event parameters
• Report: what fires, what's missing, what's misconfigured
• Read-only — doesn't modify tracking, only verifies

Deliverable

One PR with server/skills/analytics-verifier/SKILL.md

Done when

• Verified tracking on 5+ real sites using hanzi-browse (evidence in PR)
• Produces a tracking audit report
• References analytics-tracking skill for what correct implementation looks like

Difficulty: intermediate — need basic understanding of GA4/GTM
