Sentry Next.js SDK

Opinionated wizard that scans your Next.js project and guides you through complete Sentry setup across all three runtimes: browser, Node.js server, and Edge.

Invoke This Skill When

• User asks to "add Sentry to Next.js" or "set up Sentry" in a Next.js app
• User wants to install or configure @sentry/nextjs
• User wants error monitoring, tracing, session replay, logging, or profiling for Next.js
• User asks about instrumentation.ts, withSentryConfig(), or global-error.tsx
• User wants to capture server actions, server component errors, or edge runtime errors

Note: SDK versions and APIs below reflect current Sentry docs at time of writing (@sentry/nextjs ≥8.28.0). Always verify against docs.sentry.io/platforms/javascript/guides/nextjs/ before implementing.

Phase 1: Detect

Run these commands to understand the project before making any recommendations:

# Detect Next.js version and existing Sentry
cat package.json | grep -E '"next"|"@sentry/'

# Detect router type (App Router vs Pages Router)
ls src/app app src/pages pages 2>/dev/null

# Check for existing Sentry config files
ls instrumentation.ts instrumentation-client.ts sentry.server.config.ts sentry.edge.config.ts 2>/dev/null
ls src/instrumentation.ts src/instrumentation-client.ts 2>/dev/null

# Check next.config
ls next.config.ts next.config.js next.config.mjs 2>/dev/null

# Check for existing error boundaries
find . -name "global-error.tsx" -o -name "_error.tsx" 2>/dev/null | grep -v node_modules

# Check build tool
cat package.json | grep -E '"turbopack"|"webpack"'

# Check for logging libraries
cat package.json | grep -E '"pino"|"winston"|"bunyan"'

# Check for companion backend
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod ../requirements.txt ../Gemfile 2>/dev/null | head -3
