## What it does

Thirteen skills land in Claude, and they fire on their own once you ask an analytics question. Start with `analytics-profile-setup`: it interviews you about your business model, main conversion, traffic volume, ICP and data stack, then writes `analytics-profile.md` at the repo root. Every other skill reads that file, so the answers match your scale instead of generic advice.

\`analytics-diagnostic-method` is the backbone — five steps from loading the profile to framing hypotheses and presenting a conclusion. The applied skills hang off it. `traffic-change-diagnosis` walks a drill path for a traffic drop and matches fingerprints: broken tracking, bot spikes, deploy-correlated dips, campaign ramps, SEO decay. `channel-and-funnel-quality` lays volume, engagement and conversion out as a matrix. `metric-context-and-benchmarks` tells you when a metric lies. Two experiment readers cover frequentist and Bayesian cases, and `sequential-monitoring` handles honest peeking at a live dashboard.

Nothing here is tied to one vendor. Per-platform MCP invocations sit in `tool-maps/`, one file each for Amplitude, Clamp, GA4, Mixpanel and PostHog, and you can drop your own in. The event-schema and experiment skills build on the open Event Schema spec. Those two expect an `event-schema.yaml` — without it `experiment-result-reader` finds no `experiments:` section and works only from the numbers you hand it.

## When to use it
- work out why traffic dropped on Tuesday instead of staring at a chart
- separate junk traffic from real visitors by volume and conversion
- check whether 14% at the checkout step is actually low
- turn existing `track()` calls into a typed event schema
- read a running A/B test without calling a false positive

## Example prompts
- Set me up. I want the skills calibrated to my business.
- Traffic dropped 30% on Tuesday. What happened?
- Is our signup funnel broken? Pricing to checkout converts at 14%.

# analytics-skills

Analytics skills for Claude, Cursor, and other AI agents. Read web analytics like a senior analyst: diagnose traffic changes, judge channel quality, read funnels, declare typed events, and read A/B tests without the usual rookie mistakes. Ships with tool-maps for [Amplitude](tool-maps/amplitude.md), [Clamp](tool-maps/clamp.md), [GA4](tool-maps/ga4.md), [Mixpanel](tool-maps/mixpanel.md), and [PostHog](tool-maps/posthog.md); add your own under [`tool-maps/`](tool-maps/). The schema-authoring and experiment-reading skills are built on the open [Event Schema spec](https://github.com/clamp-sh/event-schema).

## What's in the box

| Skill | What it does |
|---|---|
| [`analytics-profile-setup`](skills/analytics-profile-setup/SKILL.md) | One-time interview that captures your business context (model, primary conversion, traffic range, ICP, data stack) into a local `analytics-profile.md`. Every other skill reads this file so answers are calibrated to your industry and scale. Run this first. |
| [`analytics-diagnostic-method`](skills/analytics-diagnostic-method/SKILL.md) | The spine. Five-step method: load profile, frame the question, build a MECE hypothesis tree, triangulate, present with the Pyramid Principle. Covers signal vs noise and Simpson's paradox. Referenced by every other skill. |
| [`traffic-change-diagnosis`](skills/traffic-change-diagnosis/SKILL.md) | Drill path for "why did traffic change". Fingerprints for tracking regressions, bot spikes, deploy-correlated drops, campaign ramps, SEO decay, and platform changes. Measurement checks first, always. |
| [`channel-and-funnel-quality`](skills/channel-and-funnel-quality/SKILL.md) | Volume × engagement × conversion as a matrix. Vanity-traffic detection. Expected drop-off ranges per funnel step type. Mix-shift handling. Industry-specific benchmarks. |
| [`metric-context-and-benchmarks`](skills/metric-context-and-benchmarks/SKILL.md) | What's a good bounce / engagement / duration / CVR / churn / LTV:CAC / activation, by model. When each metric lies. Minimum sample sizes before trusting a rate. |
| [`event-schema-author`](skills/event-schema-author/SKILL.md) | Authors `event-schema.yaml` from existing `track()` calls. A portable, typed declaration of every product analytics event the codebase fires. The CLI generates a TypeScript type so call sites are autocompleted and type-checked at build time. Vendor-neutral; works with any analytics SDK. |
| [`experiment-result-reader`](skills/experiment-result-reader/SKILL.md) | Read a running A/B test honestly. Pulls per-variant exposure and conversion counts, computes lift, applies sample-size and sequential-testing discipline, checks for mix-shift and sample-ratio mismatch, and returns a verdict with caveats instead of a false-positive. Reads the experiment from the `experiments:` section of `event-schema.yaml` when present. |
| [`bayesian-experiment-reader`](skills/bayesian-experiment-reader/SKILL.md) | Bayesian counterpart to `experiment-result-reader`. Beta-Binomial for CVR, Normal-Normal for continuous. Returns P(variant beats control), credible intervals, and expected loss. Ship-decision rule: ship if P(better)>95% AND expected loss < tolerance, instead of "stat sig yes/no." |
| [`sequential-monitoring`](skills/sequential-monitoring/SKILL.md) | mSPRT and confidence sequences for honest peeking. Answers "can I call this early?" without α-inflation from looking at the dashboard every day. Pairs with both experiment readers. |
| [`causal-query-classifier`](skills/causal-query-classifier/SKILL.md) | Pearl's three-rung hierarchy as a query classifier. Tags every analytics question as rung-1 (association), rung-2 (intervention), or rung-3 (counterfactual). Refuses to escalate rung-1 findings into rung-2 recommendations without an identification strategy. |
