## What it does

The skill takes numbers from three systems — an ad platform, an analytics tool and the source of truth (CRM or order system) — and explains why they disagree. Every unit of the gap gets sorted into one of three buckets: timing, definitional, or unexplained residual. The residual is never forced to zero. These systems genuinely count different things, so the aim is a small explained residual, not a zero one.

Work starts with normalization. Both sides are rolled to a common basis: conversion date, timezone, currency, conversion definition, attribution window. Skip this and the comparison is worthless, because most reported gaps shrink once both reports cover the same action over the same period. Then comes classification of each variance and an estimate of its share of the total gap.

The skill does not fix broken tracking and does not pick an attribution model. When the analysis shows a tag misfiring or dedup broken, it names the finding, quantifies its share of the gap and hands off to `mbfinotti/advertising-skills@ad-conversion-tracking`. To run it you need exported reports or each system's own values: conversions and revenue for the window, date basis, timezone, currency, attribution window and counting rule.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mbfinotti/advertising-skills --skill ad-attribution-gap -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ad-attribution-gap/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ad-attribution-gap/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mbfinotti/advertising-skills --skill ad-attribution-gap -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ad-attribution-gap/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mbfinotti/advertising-skills --skill ad-attribution-gap -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ad-attribution-gap/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mbfinotti/advertising-skills ad-attribution-gap
```

2. **Manually: put the files in place**
- File: `.github/skills/ad-attribution-gap/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mbfinotti/advertising-skills --skill ad-attribution-gap -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mbfinotti/advertising-skills --path skills/ad-attribution-gap
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ad-attribution-gap/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mbfinotti/advertising-skills --skill ad-attribution-gap -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mbfinotti/advertising-skills/tree/HEAD/skills/ad-attribution-gap/SKILL.md

## When to use it
- put a number on the gap between platform reporting and the CRM
- explain why the platform reports more conversions than the order system
- split a discrepancy into timing, definitional and residual parts
- tell a normal gap from a tracking defect
- get a defensible number for a channel budget decision

## Example prompts
- Reconcile conversions from Google Ads, GA4 and the CRM for last month and show what the gap is made of
- The platform reports more revenue than the order system. Break the difference down by cause
- Is the gap between analytics and the CRM normal, or is tracking broken somewhere?

description: "Quantify and explain the discrepancy between ad platform reporting, an analytics tool, and the source of truth (CRM or order system), classifying every unit of the gap as timing, definitional, or unexplained residual. Use whenever the user says the numbers don't match, that the platform reports more conversions or revenue than the CRM or order system, or mentions cross-platform reconciliation, double-counted conversions, an attribution discrepancy, or asks whether a reporting gap is normal - even if they never say 'attribution'. Covers B2B (CRM-anchored) and B2C/ecommerce (order-system-anchored). Do NOT use to fix broken or missing tracking - use mbfinotti/advertising-skills@ad-conversion-tracking instead."

# Attribution Gap Reconciliation

You are a marketing measurement analyst. Deliver a reconciliation report: a number on the gap between what each reporting system claims, with every unit of that number attributed to a named cause. The gap between an ad platform, an analytics tool, and the system that records the money is structural and expected - a report where the numbers match perfectly is a report where someone fabricated a number.

Apply one test to every step: does it help put a number on the gap and attribute that number to a named cause? If not, skip it.

## Boundaries - hand off, don't absorb

- Fixing or installing tracking (tags, pixels, deduplication setup) is out of scope. When the analysis concludes "a tag is misfiring" or "dedup is broken", name the finding, quantify its share of the gap, assign an owner, and hand off to `mbfinotti/advertising-skills@ad-conversion-tracking`.
- Choosing an attribution model is out of scope. Treat model differences as a cause of discrepancy to measure and neutralize, never as a decision to make. If the user asks "which model should I use", redirect them to an attribution-model selection resource.
- Ad account performance diagnosis, landing page work, and CAC/ROAS benchmarking belong to other skills.

## The discipline, ported from financial reconciliation
