## What it does

The skill parses your funnel stages, resolves each one to a measurable condition in Customer Journey Analytics, and reports how many visitors reached it. You get step-to-step conversion, drop-off counts and the worst leakage point. Handy when a team suspects one step is broken but nobody has quantified it yet.

It drives CJA through MCP tools: `findDimensions`, `findMetrics`, `searchDimensionItems`, `runReport` with `adhocSegments`, plus `findSegments` and `describeSegment`. Each stage becomes an ad hoc segment, and the measurement uses a base metric such as Unique Visitors or Sessions. A stage can be a page view, an event or membership in an existing segment.

Vague stages get one clarifying question — what counts as entering checkout, for instance. From there you can break the funnel down by device type, channel or new versus returning visitors to see which group fares worst at the problem step. The skill needs CJA access through an MCP server; without it the tool calls have nothing to talk to.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill cja-funnel-health-check -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill cja-funnel-health-check -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill cja-funnel-health-check -a cursor
```

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

```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add adobe/skills --skill cja-funnel-health-check -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/adobe/skills/tree/HEAD/plugins/adobe-cja/skills/cja-funnel-health-check/SKILL.md

## When to use it
- measure conversion between funnel stages
- find the step with the heaviest drop-off
- confirm whether a specific stage is broken
- compare funnel performance on mobile and desktop
- break drop-off down by acquisition channel

## Example prompts
- analyze our onboarding funnel: signup → step 1 → step 2 → activated
- where are users dropping off between cart and purchase
- show me fallout between these steps by device type

  Analyzes a multi-step conversion funnel to find where users drop off and which
  steps have the worst leakage. Use this skill when someone describes a journey
  or funnel and asks about conversion rates, drop-off, fallout, or step completion.
  Trigger for phrases like "analyze our onboarding funnel," "where are users
  dropping off," "what's our checkout conversion rate," "funnel analysis,"
  "show me fallout between these steps," or "which step loses the most users."

# Funnel Health Check (Customer Journey Analytics)

Turn a plain-English funnel description into a quantified step-by-step
conversion analysis. The output identifies the biggest leakage point in the
funnel and provides dimension-based breakdowns to show which audience or channel
has the worst drop-off.

Funnel health checks are most valuable when a team suspects a specific step is
broken but hasn't quantified it. This skill does the quantification in a single
conversation turn.

## CJA MCP Tools Used

- `findDimensions` — resolve page name, event, or other dimensions for step filtering
- `findMetrics` — get the base metric to measure (sessions, visitors, events)
- `searchDimensionItems` — find exact dimension values for step names
- `runReport` (with `adhocSegments`) — measure visitor counts at each funnel step
- `findSegments` — use existing segments as funnel step filters if applicable
- `describeSegment` — understand segment logic before applying as a funnel step

---

## Phase 0 — Setup

1. Call `findDataViews` to list available data views.
2. If the user hasn't specified a data view, present the list and ask which to use.
3. Call `setDefaultSessionDataViewId` with the chosen ID.
4. Ask the user to define the funnel stages if not already specified (e.g., "What are the steps in the funnel you want to analyze?").

## Phase 1 — Define Funnel Steps

### 1.1 Parse the user's funnel description

Extract the step sequence from the user's plain-English description:
- "Homepage → Product Page → Cart → Purchase"
- "Registration → Onboarding Step 1 → Onboarding Step 2 → Activated"
- "Landing Page → Lead Form → Thank You Page"

Each step must resolve to a measurable condition in CJA. A step can be:
- **Page view**: user viewed a specific page (resolved via page name dimension)
- **Event/metric**: user triggered a specific action (e.g., "Added to Cart")
- **Segment membership**: user meets a pre-built segment condition

### 1.2 Clarify ambiguous steps

If any step is vague (e.g., "checkout" without a page name), ask one question:
```
