analytics-audit

analytics-audit is a skill for Claude Code, Codex from me2resh/apexyard. It costs 27 tokens per session (1,255 once invoked), scanned A, original, MIT.

A codebase review for product analytics, which is the tracking that records actions such as sign-ups and purchases. It checks the tracking software, event names, user journeys, and dashboards.

In plain words
What is it for?
Use it to inventory tracking calls, check whether key funnel steps are recorded, and verify that analytics dashboards exist.
Why use it?
It finds missing or inconsistent tracking before launch, so reports and conversion measurements are less likely to be incomplete or misleading.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analytics-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/analytics-audit — Event Taxonomy & Coverage

Deep-dive analytics analysis. Checks that tracking is configured, events follow a naming convention, key user funnels are instrumented, and dashboards exist. Invoke when /launch-check's analytics row shows WARN or FAIL.

Process

Step 1: SDK detection

Grep for analytics SDK initialization:

  • Google Analytics / GA4: gtag, G-, UA-, analytics.js, @google-analytics
  • Mixpanel: mixpanel.init, @mixpanel
  • Amplitude: amplitude.init, @amplitude
  • PostHog: posthog.init, posthog-js
  • Plausible: plausible.io, data-domain
  • Segment: analytics.load, @segment
  • Custom: any track(, capture(, logEvent( patterns

Step 2: Event inventory

Find all tracking calls in the codebase and list them:

  • Event name
  • Where it fires (file + component/handler)
  • Properties sent with the event
  • Whether it has a consistent naming convention (snake_case, camelCase, verb_noun)

Step 3: Funnel coverage

Identify the core user funnels and check if each step is tracked:

Funnel Steps to check
Signup page_view → form_start → form_submit → signup_complete
Activation first_login → key_action_completed → aha_moment
Purchase (if applicable) pricing_view → plan_select → checkout_start → payment_complete
Retention return_visit → feature_usage → session_duration

Step 4: Output

ANALYTICS AUDIT — <project> @ <sha>

SDK: <GA4 / Mixpanel / PostHog / none>
Total events found: <N>
Naming convention: <consistent / inconsistent / none>

| # | Area | Status | Finding |
|----|------|--------|---------|
| E1 | SDK | PASS | GA4 initialized in _app.tsx |
| E2 | Events | WARN | 8 events found, 3 use camelCase, 5 use snake_case |
| E3 | Signup funnel | FAIL | form_submit tracked but signup_complete missing |
| E4 | Dashboard | WARN | No dashboard URL found in config or docs |

Event inventory:
  signup_start (pages/signup.tsx:42)
  form_submit (components/SignupForm.tsx:89)
  page_view (auto, GA4 enhanced measurement)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
