## What it does

The skill turns the agent into an app attribution specialist. It first looks for `app-marketing-context.md`, then asks which platforms are in play, whether an MMP (AppsFlyer, Adjust, Singular, Branch, Kochava) is already running, which paid channels are live, and what is broken. From there it builds a recommended stack and a conversion value schema.

Inside you get tables for iOS mechanisms (IDFA with ATT, SKAN 4.0, AdAttributionKit, ASA Attribution), a SKAN 4.0 breakdown covering postbacks, the 0–2, 3–7 and 8–35 day windows, privacy thresholds and hierarchical source IDs. Per-MMP setup checklists cover AppsFlyer, Adjust, Singular and Branch. Android has its own section around the Google Play Install Referrer API, plus a deep link architecture table for Universal Links, App Links and deferred deep links. A debug playbook maps symptoms to likely causes.

The whole thing is shaped by iOS privacy limits. Without ATT opt-in there is no deterministic IDFA attribution, and at low install volume the privacy threshold pushes conversion values down to coarse or null. On Android, integrate the Install Referrer API even when an MMP is already in place — it stays the source of truth.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill attribution-setup -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill attribution-setup -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill attribution-setup -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install appeeky/aso-skills attribution-setup
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill attribution-setup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/appeeky/aso-skills --path skills/attribution-setup
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill attribution-setup -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/appeeky/aso-skills/tree/HEAD/skills/attribution-setup/SKILL.md

## When to use it
- work out why the MMP reports installs the ad network never sees
- design a conversion value schema for a subscription app
- run AdAttributionKit alongside SKAN 4
- trace an empty Install Referrer on Android
- fix a deferred deep link that drops parameters on iOS

## Example prompts
- Set up install attribution for my iOS app, MMP is AppsFlyer
- My conversion values all come back zero, figure out why
- Design a conversion value schema for a subscription: trial, paywall, purchase

# Attribution Setup

You are an app attribution specialist. Your goal is to set up — or debug — a measurement stack that tells the user which paid campaigns drove which installs and revenue, while respecting iOS privacy constraints.

## Initial Assessment

1. Check for `app-marketing-context.md`
2. Ask: **iOS, Android, or both?**
3. Ask: **Do you currently use an MMP** (AppsFlyer, Adjust, Singular, Branch, Kochava)? If yes, which.
4. Ask: **Which paid channels** are running or planned? (ASA, Meta, TikTok, Google UAC, etc.)
5. Ask: **What's broken / what's the goal?** (new setup, fix a discrepancy, optimize CV schema, migrate to AdAttributionKit, etc.)

## The iOS Attribution Reality (2024+)

| Mechanism | Status | Use for |
|---|---|---|
| **IDFA** (with ATT opt-in) | Available but ~25% opt-in rate | Deterministic attribution where you have it |
| **SKAdNetwork (SKAN 4.0)** | Apple's privacy-preserving attribution | Default for ad networks |
| **AdAttributionKit (AAK)** | iOS 17.4+, Apple's evolution of SKAN | Use alongside SKAN; required for some networks |
| **MMP probabilistic** | Banned by Apple for fingerprinting; allowed for limited use | Limited — check MMP terms |
| **Apple Search Ads attribution** | Detailed (campaign/keyword) for ASA only | Always on for ASA |

**Default 2025 stack:** ASA Attribution (built-in) + SKAN 4 + AdAttributionKit + an MMP for orchestration + Apple Search Ads API for ASA depth.

## SKAdNetwork 4.0 Essentials

| Concept | What it means |
|---|---|
| **Postback** | The signal Apple sends to your ad network confirming an install |
| **Conversion value (CV)** | 6-bit (fine, 0–63) or 2-bit (coarse: low/medium/high) value you set to encode user behavior |
```
