Metrics Track

Other

Set up PostHog metrics plan with event funnel, KPI benchmarks, and kill/iterate/scale decision thresholds. Use when user says "set up metrics", "track KPIs", "PostHog events", "funnel analysis", "when to kill or scale", or "success metrics". Do NOT use for SEO metrics (use /seo-audit).

/metrics-track

Set up a metrics tracking plan for a project. Defines PostHog event funnel, KPI benchmarks, and kill/iterate/scale decision thresholds based on lean startup principles.

MCP Tools (use if available)

kb_search(query) — find PostHog methodology, analytics patterns

If MCP tools are not available, fall back to Grep + Read.

Methodology Reference

This skill implements metrics tracking based on lean startup principles:

Relative metrics vs niche benchmarks — compare against your own trajectory, not vanity averages
Kill/iterate/scale decision rules — data-driven thresholds for product decisions (see step 7 below)

Steps

Parse project from $ARGUMENTS.
- Read PRD for features, ICP, monetization model.
- Read CLAUDE.md for stack (iOS/Web/both).
- If empty: ask via AskUserQuestion.
Detect platform:
- iOS app → PostHog iOS SDK events
- Web app → PostHog JS SDK events
- Both → cross-platform identity (shared user ID across platforms)
Load PostHog methodology:
- If MCP available: kb_search("PostHog analytics events funnel identity")
- Otherwise: check project docs for existing analytics configuration
- Extract: event naming conventions, identity resolution, funnel pattern

Define event funnel based on PRD features:

Standard funnel stages (adapt per product):

Awareness → Acquisition → Activation → Revenue → Retention → Referral

Map to concrete events:

Stage	Event Name	Trigger	Properties
Awareness	`page_viewed`	Landing page visit	`source`, `utm_*`
Acquisition	`app_installed` or `signed_up`	First install/signup	`platform`, `source`
Activation	`core_action_completed`	First key action	`feature`, `duration_ms`
Revenue	`purchase_completed`	First payment	`plan`, `amount`, `currency`
Retention	`session_started`	Return visit (D1/D7/D30)	`session_number`, `days_since_install`
Referral	`invite_sent`	Shared or referred	`channel`, `referral_code`

Forced reasoning — metrics selection: Before defining KPIs, write out:
- North Star Metric: The ONE number that matters most (e.g., "weekly active users who completed core action")
- Leading indicators: What predicts the North Star? (e.g., "activation rate D1")
- Lagging indicators: What confirms success? (e.g., "MRR", "retention D30")
- Vanity metrics to AVOID: (e.g., total downloads without activation)

Set KPI benchmarks per stage:

KPI	Target	Kill Threshold	Scale Threshold	Source
Landing → Signup	3-5%	< 1%	> 8%	Industry avg
Signup → Activation	20-40%	< 10%	> 50%	Product benchmark
D1 Retention	25-40%	< 15%	> 50%	Mobile avg
D7 Retention	10-20%	< 5%	> 25%	Mobile avg
D30 Retention	5-10%	< 2%	> 15%	Mobile avg
Trial → Paid	2-5%	< 1%	> 8%	SaaS avg

Adjust based on product type (B2C vs B2B, free vs paid, mobile vs web).

Define decision rules (lean startup kill/iterate/scale):

## Decision Framework

**Review cadence:** Weekly (Fridays)

### KILL signals (any 2 = kill)
- [ ] Activation rate < {kill_threshold} after 2 weeks
- [ ] D7 retention < {kill_threshold} after 1 month
- [ ] Zero organic signups after 2 weeks of distribution
- [ ] CAC > 3x LTV estimate

### ITERATE signals
- [ ] Metrics between kill and scale thresholds
- [ ] Qualitative feedback suggests product-market fit issues
- [ ] One stage of funnel is dramatically worse than others

### SCALE signals (all 3 = scale)
- [ ] Activation rate > {scale_threshold}
- [ ] D7 retention > {scale_threshold}
- [ ] Organic growth > 10% week-over-week

Generate PostHog implementation snippets:

For iOS (Swift):

// Event tracking examples
PostHogSDK.shared.capture("core_action_completed", properties: [
    "feature": "scan_receipt",
    "duration_ms": elapsed
])

For Web (TypeScript):

// Event tracking examples
posthog.capture('signed_up', {
    source: searchParams.get('utm_source') ?? 'direct',
    plan: 'free'
})

Write metrics plan to docs/metrics-plan.md:

# Metrics Plan: {Project Name}

**Generated:** {YYYY-MM-DD}
**Platform:** {iOS / Web / Both}
**North Star:** {north star metric}

## Event Funnel

| Stage | Event | Properties |
|-------|-------|------------|
{event table from step 4}

## KPIs & Thresholds

| KPI | Target | Kill | Scale |
|-----|--------|------|-------|
{benchmark table from step 6}

## Decision Rules

{framework from step 7}

## Implementation

### PostHog Setup
- Project: {project name} (EU region)
- SDK: {posthog-ios / posthog-js}
- Identity: {anonymous → identified on signup}

### Code Snippets
{snippets from step 8}

## Dashboard Template
- Funnel: {stage1} → {stage2} → ... → {stageN}
- Retention: D1 / D7 / D30 cohort chart
- Revenue: MRR trend + trial conversion

*Generated by /metrics-track. Implement events, then review weekly.*

Output summary — North Star metric, key thresholds, first event to implement.

Notes

PostHog EU hosting for privacy compliance
Use $set for user properties, capture for events
Identity: start anonymous, identify() on signup with user ID
Cross-platform: same PostHog project, same user ID → unified journey
Review dashboard weekly, make kill/iterate/scale decision monthly

Common Issues

Wrong platform detected

Cause: Project has both web and iOS indicators. Fix: Skill checks package manifests. If both exist, it generates cross-platform identity setup. Verify the detected platform in the output.

KPI thresholds too aggressive

Cause: Default thresholds are industry averages. Fix: Adjust thresholds in docs/metrics-plan.md based on your niche. B2B typically has lower volume but higher conversion.

PostHog SDK not in project

Cause: Metrics plan generated but SDK not installed. Fix: This skill generates the PLAN only. Install PostHog SDK separately: pnpm add posthog-js (web) or add posthog-ios via SPM (iOS).
