What it does

Adding Error Tracking is an agent skill from spencerpauly/awesome-cursor-skills. Add Sentry error tracking, performance monitoring, and source maps to a web application.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Sentry, Next.js, npm and Vite. The repository describes itself as: A curated list of awesome skills for Cursor. The licence is CC0-1.0.

Example prompts

  • “/adding-error-tracking”

Requirements

  • Python 3
  • Node.js
  • A credential in SENTRY_AUTH_TOKEN

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Detect the framework — check package.json, config files, and directory structure to determine the stack (Next.js, React, Node.js…
  2. Install the SDK
  3. Initialize Sentry
  4. Add environment variables
  5. Add error boundary — wrap the app (or critical subtrees) with Sentry.ErrorBoundary and a fallback UI.
  6. Source maps — for production builds, configure the Sentry webpack/vite plugin to upload source maps. For Next.js, this is handled by…
  7. Test the integration — add a temporary button that throws an error to verify events appear in the Sentry dashboard.

What it can do on your machine

Read from SKILL.md and the folder at commit 99cd265. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • sentry.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SENTRY_AUTH_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Adding Error Tracking loads about 504 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~504

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Add Error Tracking (Sentry)

Use this skill when the user asks to add error tracking, crash reporting, exception monitoring, or performance tracing.

Steps

  1. Detect the framework — check package.json, config files, and directory structure to determine the stack (Next.js, React, Node.js, Python/Django/Flask, etc.).

  2. Install the SDK

    • Next.js: npx @sentry/wizard@latest -i nextjs
    • React (Vite): npm install @sentry/react
    • Node.js: npm install @sentry/node
    • Python: pip install sentry-sdk

  3. Initialize Sentry

    • For Next.js, the wizard creates sentry.client.config.ts, sentry.server.config.ts, and sentry.edge.config.ts. Verify they exist and contain the DSN.

    • For React (Vite), init in main.tsx:

      tsx
      import * as Sentry from "@sentry/react";

Sentry.init({
  dsn: import.meta.env.VITE_SENTRY_DSN,
  integrations: [Sentry.browserTracingIntegration()],
  tracesSampleRate: 1.0,
});

    • For Node.js, init at the very top of the entry file before any other imports.

  4. Add environment variables

    NEXT_PUBLIC_SENTRY_DSN=https://...@sentry.io/...
SENTRY_AUTH_TOKEN=sntrys_...
SENTRY_ORG=your-org
SENTRY_PROJECT=your-project

  5. Add error boundary — wrap the app (or critical subtrees) with Sentry.ErrorBoundary and a fallback UI.

  6. Source maps — for production builds, configure the Sentry webpack/vite plugin to upload source maps. For Next.js, this is handled by withSentryConfig in next.config.js.

  7. Test the integration — add a temporary button that throws an error to verify events appear in the Sentry dashboard.

Notes

  • Set tracesSampleRate to a lower value (e.g. 0.1) in production to control costs.
  • Add sentry.properties and .sentryclirc to .gitignore.
  • Never commit SENTRY_AUTH_TOKEN.
