Full instrumentation from day one. PostHog consolidates product analytics + feature flags + error tracking (one platform, one bill). GA4 via GTM (14-step automation, custom dimensions over events, server-side tagging). Sentry (deep error tracking + performance). Stripe (webhook-first with idempotent processing). Listmonk on Coolify (newsletters via Amazon SES SMTP relay). PLG 7-layer framework. Programmatic SEO (5 page types). Incident auto-remediation via Sentry→Inngest pipeline. AI search…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 13 — Observability and Growth
Tiered PostHog+Sentry+GA4 stacks wired from day one; feature flags, PLG patterns, incident auto-remediation.
## Instrumentation tiers
Per `_kernel/standards.md#integrations`:
- **Tier 1 (solo)** — PostHog + Workers Tracing OTLP (2 vendors max, cookie-free, free tier covers <10k MAU)
- **Tier 2 (enterprise)** — + Sentry `@sentry/cloudflare` v9 + GA4/GTM + Axiom
- **Tier 3 (LLM-heavy >10k calls/mo)** — + AI Gateway
## PostHog (Tier 1 cornerstone)
- Snippet on every HTML page w/ `persistence:'memory'` (cookie-free); `capture_pageview` + `capture_pageleave` + `autocapture:true`
- Unified platform: product analytics + feature flags + session replay + error tracking
- CSP: `script-src` + `connect-src` for posthog domain
- Per-feature event naming: `<feature>:<action>` (`signup:complete`, `editor:save`, `share:copy`)
## Sentry (Tier 2)
- `@sentry/cloudflare` v11 (stream trace lifecycle default since 11.0) + `withSentry` wrapper; project via `mcp__sentry__create_project` (org:`megabyte-labs`)
- `SENTRY_DSN` via `wrangler secret put`
- Pattern: `withSentry(env => ({ dsn, tracesSampleRate: 1.0, sendDefaultPii: false }), worker)`

How to install
mdr add heymegabyte/agent-skills/observability-and-growth@sha256:47f92299344fbec4The line at the top of this page pins the label v2.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
