How to use the Error Monitoring Setup agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Error Monitoring Setup agent skill is a written checklist and guidance package for AI coding agents that helps check and improve production error monitoring in a web project. It is aimed at developers launching a production web app, teams reviewing incident response readiness, and front-end engineers auditing existing monitoring code. After this guide you will know what the skill does, how to install it, and how to ask for it in plain language.
Error Monitoring Setupthedaviddias/Front-End-Checklist · MIT Download the skill Quick start
- 1Download the ZIP. Get the error-monitoring skill ZIP from this page.
- 2Unzip into a skills folder. Place the folder in ~/.claude/skills/ for personal use or in your project's .claude/skills/ folder.
- 3Or upload in the Claude apps. Go to Settings → Capabilities → Skills and upload the ZIP.
- 4Prepare your monitoring account. Create or locate your error monitoring service account and its DSN or API key, since the skill does not include it.
- 5Ask in plain language. Describe your goal, such as checking whether production errors are captured.
- 6Review the changes. Read the code the agent proposes, especially initialisation and alert settings, before deploying.
What does the error-monitoring skill make the agent do?
When installed, the agent can check whether a web project has production error monitoring, such as Sentry, Datadog or Bugsnag, capturing crashes, unhandled promise rejections, framework errors, failed network requests and Core Web Vitals.
It can also help integrate an SDK, tag events with release and environment, set alert thresholds, and review monitoring code for patterns that hide errors.
- Check: is a monitoring service configured and capturing unhandled errors, promise rejections and React-level errors?
- Fix: integrate an SDK, configure environment and release tagging, capture failed requests and RUM metrics, and set alerts.
- Review: flag missing user context, absent release tagging, overly broad event filters and code that swallows errors.
How do you install the error-monitoring skill?
Download the ZIP from the skill's page on this directory and unzip it. For a personal install, place the folder in ~/.claude/skills/. For a single project, place it in that project's .claude/skills/ folder.
In the Claude apps, you can instead upload the ZIP under Settings → Capabilities → Skills.
- Personal install: ~/.claude/skills/error-monitoring/
- Project install: .claude/skills/error-monitoring/ inside your project
- Or upload the ZIP in the Claude apps under Settings → Capabilities → Skills
What files does the skill contain?
The skill is made of two files. SKILL.md holds the description, the quick reference checklist and the four working modes (check, fix, explain, code review). references/rule.md holds longer material, including installation and framework-specific code examples.
- SKILL.md: metadata, quick reference and workflow summary
- references/rule.md: full implementation details and examples
How do you trigger the skill with natural requests?
You do not need a special command. Describe what you want in plain language that matches the skill's purpose: setting up a new project's production observability, reviewing incident response readiness, or finding out why errors are going undetected.
- Set up production error monitoring for this new React app.
- Check whether our project captures unhandled promise rejections and failed network requests.
- Review our Sentry initialisation code and tell me what might be hiding errors.
- Why are we not getting alerts for production errors? Investigate our setup.
What do you need before you start?
You need a web project to modify. The examples reference JavaScript and React. If you want the agent to integrate a vendor SDK such as Sentry, Datadog or Bugsnag, you also need an account with that service and its DSN or API key. The skill does not create accounts or handle billing, and the vendor account is not included.
The skill runs no scripts and uses no network access. It is guidance the agent follows while working on your code.
- A web project to modify
- An error monitoring service account plus DSN or API key, if integrating a vendor SDK
- Installation example in the source: pnpm add @sentry/react for plain React or pnpm add @sentry/nextjs for Next.js
pnpm add @sentry/reactWhat safety points should you review?
The skill itself runs no scripts and makes no network calls. However, adding a third-party SDK sends error data to an outside service. That data may include user context, so review it for privacy compliance before shipping.
The example configuration disables monitoring outside production (enabled: process.env.NODE_ENV === 'production'), which avoids noise during development. Check that your own config matches your needs.
- Error events may include user context sent to a third-party service; review privacy compliance.
- The skill runs no scripts and uses no network.
- Keep DSNs and API keys in environment variables, as the example does with process.env.
Tips for getting good results
Give the agent your framework and monitoring vendor up front. Ask for one mode at a time, such as a review of existing code before a set-up request, so changes are easier to check.
The skill is estimated at 30 minutes for a developer of intermediate difficulty, according to the source material.
- Name the framework (React, Next.js) and the vendor (Sentry, Datadog, Bugsnag).
- Ask for a review first on existing projects.
- Check each change to the initialisation code before deploying.
What people use it for
- Setting up Sentry in a new React app so unhandled exceptions and promise rejections reach a dashboard.
- Auditing existing monitoring initialisation code for filters or patterns that swallow errors.
- Checking whether release and environment tags are attached to events.
- Investigating why production errors are going unnoticed and what alerting is missing.
- Reviewing incident response readiness for a team launching a production web app.
Frequently asked questions
How do I install the error-monitoring agent skill?
Download the ZIP from the skill's page and unzip it into ~/.claude/skills/ for personal use, or into a project's .claude/skills/ folder. In the Claude apps you can also upload the ZIP under Settings → Capabilities → Skills.
Does the error-monitoring skill need an account or API key?
The skill itself does not include one. If you want the agent to integrate a vendor SDK such as Sentry, Datadog or Bugsnag, you need your own account and its DSN or API key.
Is the error-monitoring skill free?
The source material states the skill is licensed under MIT. It does not list prices, so check the vendor of any monitoring service you choose for its own pricing.
Does the skill run scripts or use the network?
According to the source, the skill runs no scripts and uses no network. It consists of a written checklist and guidance. Any SDK you add will send error data to its vendor, so review that for privacy.
Which error monitoring tools does the skill support?
The source names Sentry, Datadog and Bugsnag as examples of services the skill can work with. It does not say whether other tools are covered.
Can I use this skill for local debugging only?
Not really. The skill targets production observability and adds setup work, so for purely local debugging it is not the best fit.

Our verdict
Use this skill if you are launching a production web app or auditing monitoring code and want an agent to check for gaps such as missing release tags, unhandled rejections or swallowed errors. Pick something else if you only need local debugging, or if you expect the agent to choose a vendor and manage accounts, since it does neither.
