analytics

An agent skill by coreyhaines31, from coreyhaines31/marketingskills. Tags: analytics, dashboard, data, tracking, validation.

What it does

When the user wants to set up, improve, or audit analytics tracking and measurement. Also use when the user mentions "set up tracking," "GA4," "Google Analytics," "conversion tracking," "event tracking," "UTM parameters," "tag manager," "GTM," "analytics implementation," "tracking plan," "how do I measure this," "track conversions," "Mixpanel," "Segment," "are my events firing," or "analytics isn't working." Use this whenever someone asks how to know if something is working or wants to measure marketing results. For choosing attribution models, comparing multi-touch/MMM/incrementality, or reconciling conflicting numbers across tools, see attribution. For A/B test measurement, see ab-testing.

Safety box score

Grade A, minimal risk: 9 of 100 risk points, rated 2026-09-22. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This is a documentation-only analytics skill for GA4/GTM, UTM planning, and tracking validation. It does not ship executable scripts, but it does point the agent at hidden context files and includes examples that read browser cookies and handle identity data.

Category levels, from 0 (none) to 3 (high)
CategoryLevelWhy
Code & shell execution0 (none)No native scripts, shell commands, or code execution are shipped; the files are plain markdown with code examples only.
Network access0 (none)The skill does not download code or send data to remote hosts; it only references external documentation links and analytics tools in prose.
Filesystem reach1 (low)SKILL.md tells the agent to read hidden context files if present: "If `.agents/product-marketing.md` exists (or `.claude/product-marketing.md`, or the legacy `product-marketing-context.md` filename...) read it before asking questions."
Secrets & credentials1 (low)The GTM reference includes a helper that reads browser cookies, e.g. `document.cookie.match('(^|;) ?user_id=([^;]*)(;|$)')`, which can surface identifier values if reused carelessly.
Privilege & persistence0 (none)There is no sudo, global install, service registration, shell startup editing, or OS-level configuration in the skill files.
Instruction hijack surface0 (none)The content does not instruct the agent to ignore its rules, hide information, or follow remote instructions; it is ordinary implementation guidance.
Irreversible actions0 (none)The skill advises on tracking and measurement only; it does not send messages, deploy, publish, pay, book, or delete anything.
Transparency0 (none)All shipped content is readable markdown; there are no binaries, minified bundles, base64 blobs, or downloaded installers.
