Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00076 | $0.04797 |
| Opus 5 | $0.00038 | $0.02398 |
| Sonnet 5 | $0.00015 | $0.00959 |
| Haiku 4.5 | $0.00008 | $0.00480 |
Grade A, and why
sentry-react-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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sentry React SDK
Opinionated wizard that scans your React project and guides you through complete Sentry setup.
Invoke This Skill When
- User asks to "add Sentry to React" or "set up Sentry" in a React app
- User wants error monitoring, tracing, session replay, profiling, or logging in React
- User mentions
@sentry/react, React Sentry SDK, or Sentry error boundaries - User wants to monitor React Router v5/v6/v7 non-framework navigation, Redux state, or component performance
If project is React Router Framework mode using @sentry/react-router, use sentry-react-router-framework-sdk instead of this skill.
Note: SDK versions and APIs below reflect current Sentry docs at time of writing (
@sentry/react≥8.0.0). Always verify against docs.sentry.io/platforms/javascript/guides/react/ before implementing.
Phase 1: Detect
Run these commands to understand the project before making any recommendations:
# Detect React version
cat package.json | grep -E '"react"|"react-dom"'
# Check for existing Sentry
cat package.json | grep '"@sentry/'
# Detect router and framework mode hints
cat package.json | grep -E '"react-router-dom"|"react-router"|"@react-router/"|"@tanstack/react-router"|"@sentry/react-router"'
# Detect state management
cat package.json | grep -E '"redux"|"@reduxjs/toolkit"'
# Detect build tool
ls vite.config.ts vite.config.js webpack.config.js craco.config.js 2>/dev/null
cat package.json | grep -E '"vite"|"react-scripts"|"webpack"'
# Detect logging libraries
cat package.json | grep -E '"pino"|"winston"|"loglevel"'
# Check for companion backend in adjacent directories
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod ../requirements.txt ../Gemfile ../pom.xml 2>/dev/null | head -3
What to determine:
| Question | Impact |
|---|---|
| React 19+? | Use reactErrorHandler() hook pattern |
| React <19? | Use Sentry.ErrorBoundary |
@sentry/react already present? |
Skip install, go straight to feature config |
React Router Framework mode indicators (@sentry/react-router, @react-router/*)? |
Use sentry-react-router-framework-sdk |
react-router-dom v5 / v6 / v7? |
Determines which router integration to use |
@tanstack/react-router? |
Use tanstackRouterBrowserTracingIntegration() |
| Redux in use? | Recommend createReduxEnhancer() |
| Vite detected? | Source maps via sentryVitePlugin |
CRA (react-scripts)? |
Source maps via @sentry/webpack-plugin in CRACO |
| Backend directory found? | Trigger Phase 4 cross-link suggestion |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

sentry-react-sdk is a skill published in the GitHub repository getsentry/sentry-for-ai (255 stars, last pushed 4d ago), licensed MIT. It adds 76 tokens to every session and 4,797 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
