# /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 1. **Parse project** from `$ARGUMENTS`. - Read PRD for features, ICP, monetization model. - Read CLAUDE.md for stack (iOS/Web/both). - If empty: ask via AskUserQuestion. 2. **Detect platform:** - iOS app → PostHog iOS SDK events - Web app → PostHog JS SDK events - Both → cross-platform identity (shared user ID across platforms) 3. **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 4. **Define event funnel** based on PRD features: Standard funnel: `Awareness → Acquisition → Activation → Revenue → Retention → Referral` See `references/kpi-benchmarks.md` for the full event table, KPI thresholds...
