# Sentry Skill

Access Sentry data via the API for debugging and investigation. Uses auth token from `~/.sentryclirc`.

## Quick Reference

| Task | Command |
|------|---------|
| Find errors on a date | `search-events.js --org X --start 2025-12-23T15:00:00 --level error` |
| List open issues | `list-issues.js --org X --status unresolved` |
| Get issue details | `fetch-issue.js <issue-id-or-url> --latest` |
| Get event details | `fetch-event.js <event-id> --org X --project Y` |
| Search logs | `search-logs.js --org X --project Y "level:error"` |

## Common Debugging Workflows

### "What went wrong at this time?"

Find events around a specific timestamp:

```bash
# Find all events in a 2-hour window
./scripts/search-events.js --org myorg --project backend \
  --start 2025-12-23T15:00:00 --end 2025-12-23T17:00:00

# Filter to just errors
./scripts/search-events.js --org myorg --start 2025-12-23T15:00:00 \
  --level error

# Find a specific transaction type
./scripts/search-events.js --org myorg --start 2025-12-23T15:00:00 \
  --transaction process-incoming-email
```

### "What errors have occurred recently?"

```bash
# List unresolved errors from last 24 hours
./scripts/list-issues.js --org myorg --status unresolved --level error --period 24h

# Find high-frequency issues
./scripts/list-issues.js --org myorg --query "times_seen:>50" --sort freq

# Issues affecting users
./scripts/list-issues.js --org myorg --query "is:unresolved has:user" --sort user
```

### "Get details about a specific issue/event"

```bash
# Get issue with latest stack trace
./scripts/fetch-issue.js 5765604106 --latest
./scripts/fetch-issue.js https://sentry.io/organizations/myorg/issues/123/ --latest
./scripts/fetch-issue.js MYPROJ-123 --org myorg --latest

# Get specific event with all breadcrumbs
./scripts/fetch-event.js abc123def456 --org myorg --project backend --breadcrumbs
```

### "Find events with a specific tag"

```bash
# Find by custom tag (e.g., thread_id, user_id)
./scripts/search-events.js --org myorg --tag thread_id:th_abc123

# Find by user email
./scripts/search-events.js --org myorg --query "user.email:*@example.com"
```

## Fetch Issue

```bash

- `--json` - Output raw JSON

**Output includes:**
- Title, culprit, status, level
- First/last seen timestamps
- Event count and user impact
- Tags and environment info
- With `--latest`: stack trace, request details, breadcrumbs, runtime context

## Tips for Debugging

1. **Start broad, then narrow down**: Use `search-events.js` with a time range first, then drill into specific events

2. **Use breadcrumbs**: The `--breadcrumbs` flag on `fetch-event.js` shows the full history of what happened before an error

3. **Look for patterns**: Use `list-issues.js --sort freq` to find frequently occurring problems

4. **Check related events**: If you find one event, look for others with the same transaction name or trace ID

5. **Tags are your friend**: Custom tags like `thread_id`, `user_id`, `request_id` help correlate events
