Frontend Observability (the field side)
Portable skill — readable by Claude Code, OpenCode, Codex, Cursor, Windsurf, and others. This skill describes a field-side observability system — event taxonomy, provider fan-out, real-user vitals, error reporting, consent — not a dashboard or a specific vendor. It is the field complement to the frontend-lighthouse skill: Lighthouse is the lab gate (synthetic, pre-merge); this is the field (what real users actually experience). It lives in a
services/analytics/module per the frontend-architecture skill.
The goal: you can answer "what are real users doing, and what are they experiencing?" — with a
typed event vocabulary (no stringly-typed track("clicked_thing") scattered everywhere), a
fan-out that is best-effort (a broken provider never breaks the app), real Core Web Vitals
from the field, and consent respected before anything fires.
