Identify the precise location of bugs in source code, modules, and systems. Use this skill when debugging applications, investigating test failures, analyzing error reports, tracing runtime issues, or performing root cause analysis. Analyzes stack traces, error messages, failing tests, and code patterns to pinpoint buggy functions, classes, files, or modules with confidence rankings and supporting evidence.

# Bug Localization

Precisely identify the location of bugs in source code by analyzing error messages, stack traces, failing tests, and code patterns. Provides ranked suspect locations with confidence scores and evidence.

## Core Capabilities

### 1. Error Analysis

Extract information from error sources:
- **Stack traces** - Parse and analyze call stacks
- **Error messages** - Interpret exception details
- **Failing tests** - Analyze test failures and assertions
- **Crash reports** - Process crash dumps and core files
- **Log messages** - Trace execution through logs
