bug-localization

# 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 - **Debugger output** - Interpret breakpoint and watch data ### 2. Code Analysis Examine code for bug indicators: - **Data flow** - Trace variables and values - **Control flow** - Analyze execution paths - **Type mismatches** - Detect type-related issues - **Null/undefined access** - Find potential null dereferences - **Boundary violations** - Detect array/buffer overflows - **Concurrency issues** - Identify race conditions ### 3. Suspect Ranking Prioritize likely bug locations: - **Confidence scores** - Rank suspects by likelihood - **Evidence strength** - Quantify supporting evidence - **Historical data** - Consider past bug patterns - **Code complexity** - Factor in cyclomatic complexity - **Recent changes** - Weigh recent modifications - **Code churn** - Consider frequently modified code ### 4. Investigation Guidance Provide actionable next steps: - **Verification steps** - How to confirm the bug - *...
