Quality audit: onboarding-pulse skill

Run the onboarding-pulse skill end-to-end and evaluate output quality. Check: 1. Step 0 (data freshness) — script runs, stale warning logic correct? 2. Step 1 (context) — data-context.md is read and understood? 3. Step 1.5 (top-of-funnel) — runs if signup-events.csv present, skips correctly if absent? 4. Step 2 (scripts) — all 4 scripts run without error? Output consistent? 5. Step 3 (RAG thresholds) — deltas computed correctly? Statuses assigned per rules? 6. Step 4 (pulse.md) — follows template? RAG table correct? Watchlist identifies right merchants? Cancelled trials table has correct flags? Narrative adds value beyond the table? 7. Step 5 (today.md) — individual journeys correct? Timeline tables accurate? Also evaluate: does the skill still rely on manual CSV Prerequisites (not yet migrated to Redshift MCP)? If so, note as a gap. Grade each step: Pass / Minor issues / Major issues.
