sentry-nextjs-sdk

sentry-nextjs-sdk is a skill for Claude Code, Codex from guillermoscript/lms-front. It costs 74 tokens per session (4,605 once invoked), scanned A, a copy of sentry-nextjs-sdk, MIT.

A guided setup for adding Sentry error monitoring to a Next.js application. Next.js is a web framework, and Sentry records errors and related application activity across browser, server, and edge code.

In plain words
What is it for?
Use it to install or configure the Sentry Next.js SDK, error reporting, tracing, session replay, logging, profiling, AI monitoring, or scheduled-task monitoring.
Why use it?
It helps configure monitoring across the different places where a Next.js app runs, while checking the project's router and existing setup first. This reduces missed errors caused by incomplete configuration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sentry-nextjs-sdk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
