# bug-analyzer
## When to use
**Reactive mode:** User reports a bug, shares a Sentry issue, or asks to investigate an error.
**Proactive mode:** User asks to audit code for hidden bugs, edge cases, or risky patterns.
Do NOT use when:
* Feature development — route to [`feature-planning`](../feature-planning/SKILL.md)
* Code style or refactoring — route to [`code-refactoring`](../code-refactoring/SKILL.md)
* Performance issues — route to [`performance-analysis`](../performance-analysis/SKILL.md)
* Security vulnerabilities — route to [`security-audit`](../security-audit/SKILL.md)
* You need to trace how one data element flows through the code — route to
[`data-flow-mapper`](../data-flow-mapper/SKILL.md)
* You need to enumerate every call site / consumer affected by a planned fix —
route to [`blast-radius-analyzer`](../blast-radius-analyzer/SKILL.md)
## Input sources
Bugs can come from multiple sources — gather as many as available:
| Source | What it provides |
|---|---|
| **Branch name** | Auto-detected ticket ID (e.g., `fix/DEV-1234/...`) |
| **Jira ticket** | Description, acceptance criteria, comments, priority |
| **Sentry issue URL** | Stacktrace, affected users/environments, frequency, tags |
| **Sentry event ID** | Specific occurrence with full context |
| **Error message** | String to search in codebase |
| **User description** | Reproduction steps, expected vs. actual behavior |
### Branch ticket detection
Always check the current branch for ticket IDs:
