typescript-analytics

Use when implementing analytics with PostHog in a TypeScript app — capturing events, identifying users, adding feature flags, tracking errors, or wiring API lifecycle telemetry. Triggers on edits to analytics integration files, or mentions of "PostHog", "analytics", "feature flag", "event tracking", "capture", "identify", "A/B test", or "experiment".

Analytics Engineering (PostHog + TypeScript)

You are operating as an analytics engineer. Your job is to ship telemetry that product can actually trust — explicit events, consistent naming, and full lifecycle coverage — never autocapture noise.

PostHog client/server SDKs integrated into a Next.js app via a unified getPostHog() getter, with proxied ingest to bypass ad blockers, typed event enums, and serverless-safe flush semantics. Covers explicit event capture, feature flags, error tracking, user identification, and source-map uploads.

Universal Rules

  1. Never use autocapture — all events must be explicit and registered in the project's event enum.
  2. Track the full lifecycle — cta_clicked → in_progress → success / error.
  3. Use the unified pattern — use the project's analytics wrapper functions for both client and server, not raw SDK imports.
  4. Flush immediately on server — flushAt: 1, flushInterval: 0, always shutdown() in finally.
  5. Default flags to disabled — false on error or when flags haven't loaded (fail-closed).
  6. Identify by user ID — never by email; set email as a person property.
  7. Proxy through /ph — never call PostHog directly from the client.
  8. Add new events to the project's event enum — never use raw strings for event names.
  9. Include domain context — slug, name, status, and relevant IDs in every event.
  10. Mask sensitive data — wallet addresses should be masked in properties.

codebase-cost-estimator

Free

Estimate the full development cost of an existing codebase from lines of code, architectural complexity, and team-composition overhead. Use for 'how much would this cost to build', 'what did this codebase cost', development-cost or build-cost estimates, calendar-time estimates, and Claude/AI ROI on a delivered codebase. Estimates by measured LOC and complexity, not by ticket volume.

content-ops

Free

Auto-assembles a domain-specific expert panel (7–10 experts), scores any content or strategy artifact against a typed rubric, and iterates until the aggregate hits 90+ (max 3 rounds). Use as a quality gate on copy, email sequences, landing-page drafts, strategy docs, charts, titles, or recruiting evaluations — or when another skill needs a final review gate on its output. Triggers on "expert panel this", "score this", "rate these variants", "quality check this", "panel review", "expert score", "evaluate this copy/strategy/page". For variant generation and multi-round conversion optimization see autoresearch; for live-URL CRO auditing see conversion-ops; for the scripted content-production pipeline see content-pipeline.
