GA4 Site Blood Test

What it does

GA4 Site Blood Test is a diagnostic agent that connects to your Google Analytics 4 property and performs an end-to-end assessment of your website's health. It collects engagement and conversion metrics segmented by device (mobile, desktop, tablet), compares them against industry reference ranges, and classifies each metric as healthy, warning, or critical. The diagnostic layer is fully deterministic: the same data always produces the same 0–100 health score, with no LLM involved in this step. A language model (Claude or OpenAI) is engaged only at the synthesis stage, where it writes an actionable, prioritized remediation plan for the abnormal findings. If no API key is provided, the agent degrades gracefully to a template-based output rather than failing. A built-in recommendation engine maps each finding to real B2B SaaS products — CRO tools, personalization platforms, and marketing automation solutions — clarifying which to evaluate. The agent also records each run to a local database, reporting score deltas and metric-level trends against the previous scan. Designed for growth teams, performance marketers, and e-commerce operators, it delivers a fast, repeatable GA4 health audit without manually navigating through dashboards.

Tools (8)

Tools the agent exposes — your AI client calls them automatically when it needs them.

• run_health_check — Run the full GA4 site blood test: collect metrics, diagnose issues, compute a health score 0–100, generate an LLM prescription, and return vendor recommendations.
• get_metrics_panel — Fetch raw GA4 health panel metrics broken down by device category (mobile/desktop/tablet).
• get_worst_pages — Return the top-N worst-performing pages by bounce rate with average session duration.
• analyze_findings — Run pure deterministic analysis on a HealthPanel — no LLM, no I/O. Returns scored findings.
• get_prescription — Given a set of findings, call Claude or OpenAI to generate an actionable prescription. Falls back to template if LLM is unavailable.
• list_available_metrics — List all tracked metrics with their healthy/warning/critical thresholds and direction.
• search_vendor_catalog — Search the B2B SaaS vendor catalog by capability keyword or problem description.
• match_to_finding — Given a specific finding (metric + status + device), surface ranked vendor product candidates that typically address it.
