## What it does

The skill describes Sentry v8 patterns for service code. Controllers can route failures through `BaseController`; standalone routes use `Sentry.captureException` with tags and extra context. Workflow errors can carry operation metadata, while database calls and other async work are wrapped in `Sentry.startSpan`.

Cron scripts import `../instrument` immediately after the shebang, then record the job as a Sentry span and capture failures. The examples use `@sentry/node`, `@sentry/profiling-node`, `SENTRY_DSN`, and `NODE_ENV`. A `console.error` call without sending the exception to Sentry breaks the skill’s required error-handling pattern.

## Requirements
- Works with: Sentry

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add diet103/claude-code-infrastructure-showcase --skill error-tracking -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/error-tracking/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/error-tracking/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add diet103/claude-code-infrastructure-showcase --skill error-tracking -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/error-tracking/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add diet103/claude-code-infrastructure-showcase --skill error-tracking -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/error-tracking/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install diet103/claude-code-infrastructure-showcase error-tracking
```

2. **Manually: put the files in place**
- File: `.github/skills/error-tracking/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add diet103/claude-code-infrastructure-showcase --skill error-tracking -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/diet103/claude-code-infrastructure-showcase --path .claude/skills/error-tracking
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/error-tracking/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add diet103/claude-code-infrastructure-showcase --skill error-tracking -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/diet103/claude-code-infrastructure-showcase/tree/HEAD/.claude/skills/error-tracking/SKILL.md

## When to use it
- add Sentry handling to a controller
- capture route exceptions with request context
- attach workflow metadata to failures
- trace a database query with a Sentry span
- instrument a cron job

## Example prompts
- Add error handling to this controller through `BaseController` and send every exception to Sentry.
- Instrument this cron script: import `../instrument` after the shebang and create a span for the job.
- Wrap `PrismaService.main.userProfile.findMany` in a Sentry span with database model and operation attributes.

description: Add Sentry v8 error tracking and performance monitoring to your services. Use this skill when adding error handling, creating new controllers, instrumenting cron jobs, or tracking database performance. ALL ERRORS MUST BE CAPTURED TO SENTRY - no exceptions.

# Sentry Integration Skill

## Purpose
This skill enforces comprehensive Sentry error tracking and performance monitoring across all services following Sentry v8 patterns.

## When to Use This Skill
- Adding error handling to any code
- Creating new controllers or routes
- Instrumenting cron jobs
- Tracking database performance
- Adding performance spans
- Handling workflow errors

## 🚨 CRITICAL RULE

**ALL ERRORS MUST BE CAPTURED TO SENTRY** - No exceptions. Never use console.error alone.

## Current Status

### Example: API Service ✅ Complete
- Sentry v8 fully integrated
- All workflow errors tracked
- Background job processors instrumented
- Test endpoints available

## Sentry Integration Patterns

### 1. Controller Error Handling

```typescript
// ✅ CORRECT - Use BaseController
import { BaseController } from '../controllers/BaseController';

export class MyController extends BaseController {
    async myMethod() {
        try {
            // ... your code
        } catch (error) {
            this.handleError(error, 'myMethod'); // Automatically sends to Sentry
        }
    }
}
```

### 2. Route Error Handling (Without BaseController)

```typescript
import * as Sentry from '@sentry/node';

router.get('/route', async (req, res) => {
    try {
        // ... your code
    } catch (error) {
        Sentry.captureException(error, {
            tags: { route: '/route', method: 'GET' },
            extra: { userId: req.user?.id }
        });
        res.status(500).json({ error: 'Internal server error' });
    }
});
```

### 3. Workflow Error Handling

Example of a domain-specific Sentry helper from the original production project. If you build a helper like this for your domain, the call site looks like:

```typescript
import { WorkflowSentryHelper } from '../workflow/utils/sentryHelper';

WorkflowSentryHelper.captureWorkflowError(error, {
    workflowCode: 'INVOICE_APPROVAL',
    instanceId: 123,
    stepId: 456,
    userId: 'user-123',
    operation: 'stepCompletion',
    metadata: { additionalInfo: 'value' }
});
```

Without a helper, plain Sentry works everywhere:

```typescript
Sentry.captureException(error, {
    tags: { operation: 'stepCompletion' },
    extra: { workflowCode: 'INVOICE_APPROVAL', instanceId: 123, userId: 'user-123' }
});
```

### 4. Cron Jobs (MANDATORY Pattern)

```typescript
#!/usr/bin/env node
// FIRST LINE after shebang - CRITICAL!
import '../instrument';
import * as Sentry from '@sentry/node';

async function main() {
````
