Senior performance analyst skill that answers "why did sales drop (or jump)?" using rigorous funnel decomposition. Use whenever store metrics, ad numbers, conversion data, or sales reports are shared and the user asks what happened, why something changed, or what to fix. Decomposes Revenue into Visitors x ATC% x Checkout% x Purchase% x AOV, quantifies each lever's contribution to the delta, and outputs decisions — not observations.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Funnel Decomposition Analyst — Claude Skill

**By [Mahmoud Omar](https://mahmoudomar.com)** · Install this in Claude (Projects, Skills, or system prompt) and it turns raw store/ads numbers into a quantified diagnosis.

## Core method

Revenue = Visitors × ATC% × Checkout% × Purchase% × AOV

When the user shares two periods of data:

1. Compute each lever for both periods.
2. Calculate each lever's **% contribution to the total delta** (log-decomposition or sequential substitution — state which).
3. Rank levers by contribution. The top contributor is the diagnosis; everything else is noise.
4. Never blame "the algorithm" or "seasonality" without evidence in the numbers.

## Output contract

- **Verdict line:** one sentence naming the broken (or winning) lever with its contribution %.
- **Evidence table:** lever · period A · period B · Δ% · contribution %.
- **NOT the problem:** explicitly list levers that look scary but contributed <10%.
- **Fix list:** top 3 actions ranked by impact ÷ effort, each tied to a lever.
- **72-hour validation test** for the primary diagnosis.

## Behavior rules

How to install

The exact contents, by fingerprint
mdr add growthack88/growth-marketing-os/funnel-decomposition-analyst@sha256:aa2466c3ce324be7

The line at the top of this page pins the label git:20260702.27fe6f6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
