Check Analytics

Audit existing Google Analytics implementation. Checks for common issues, missing configurations, and optimization opportunities.

Security Scan

The skill is an instruction-only analytics auditor whose requested resources and instructions are consistent with its stated purpose and do not ask for unrelated credentials or installs.

Purpose & Capability

Name and description match the instructions: the SKILL.md describes searching a codebase for Google Analytics/GTM/third-party analytics patterns and producing an audit report. It does not request unrelated binaries, credentials, or config paths.

Instruction Scope

Instructions are scoped to locating analytics integrations and producing a report. They imply reading project files (searching for patterns like 'gtag', 'GTM-', etc.), which is appropriate for this audit task. The guidance is somewhat high-level (no exact file-glob commands or paths), so the agent will have discretion about how broadly to scan the repository; that is expected for an audit but worth noting.

Install Mechanism

No install spec and no code files — instruction-only. Nothing will be downloaded or written by the skill itself.

Credentials

The skill declares no environment variables, credentials, or config paths. The checks described (IDs, debug flags, async loading, consent mode, etc.) don't require secrets or external credentials, so no disproportionate access is requested.

Persistence & Privilege

always is false and the skill is user-invocable. The skill does not request permanent presence or modify other skills or system settings.

Assessment

This skill is instruction-only and appears internally consistent for auditing analytics code. Before installing or running it: (1) be aware the audit requires reading your project files — run it against a non-sensitive or sanitized copy if you have private data; (2) the SKILL.md is high-level about where to search, so review the agent's reported file paths and results for false positives; (3) the skill does not request network exfiltration or credentials, but the agent runtime may have network access — do not allow the agent to send sensitive findings outside your environment unless you trust the destination; (4) note it recommends redacting measurement IDs (good practice) — verify redaction is actually applied in any exported reports.

Analytics Audit Skill

You are auditing the Google Analytics implementation in this project.

Step 1: Find Existing Analytics

Search for analytics code:

• gtag or dataLayer references
• Google Tag Manager (GTM-)
• Universal Analytics (UA-) - deprecated
• GA4 Measurement IDs (G-)
• Third-party analytics (Mixpanel, Amplitude, Plausible, etc.)

Step 2: Generate Audit Report

Create a report with these sections:

Current Setup

• Framework detected
• Analytics provider(s) found
• Measurement ID(s) found (redact last 6 chars for security: G-XXXX******)
• Implementation method (gtag.js, GTM, npm package)

Issues Found

Check for:

1. Deprecated UA properties - Universal Analytics sunset July 2024
2. Missing pageview tracking for SPAs
3. Hardcoded Measurement IDs (should use env vars)
4. Missing TypeScript types for gtag
5. No consent mode implementation
6. Debug mode in production (check for debug_mode: true)
7. Duplicate script loading
8. Missing error boundaries around analytics code
9. Blocking script loading (should be async)
10. No fallback for ad-blocker scenarios

Recommendations

Provide actionable fixes ranked by priority:

• 🔴 Critical (breaking/deprecated)
• 🟡 Warning (best practice violations)
• 🟢 Suggestion (optimizations)
