runtime-error-explainer

Explains runtime errors and compilation failures with actionable debugging guidance. Use when Python or Java code throws runtime exceptions (NullPointerException, TypeError, AttributeError, etc.), compilation errors (syntax errors, type mismatches, import failures), or dependency issues. Analyzes error messages, stack traces, and code context to identify root causes and provide concrete fixes with examples. Distinct from test-related errors - focuses on errors during normal code execution and build processes.

# Runtime Error Explainer

Analyze runtime and compilation errors with clear explanations and actionable fixes.

## Core Capabilities

This skill helps debug runtime and compilation errors by:

1. **Parsing error output** - Extract key information from error messages and stack traces
2. **Identifying root causes** - Determine why errors occur during execution or compilation
3. **Explaining clearly** - Translate technical errors into understandable language
4. **Providing fixes** - Suggest concrete code changes with before/after examples
5. **Preventing recurrence** - Recommend best practices to avoid similar errors
