Use this agent PROACTIVELY when you need to investigate, understand, and fix a bug in the codebase. The agent will perform deep analysis to find the root cause, create tests to reproduce the issue, implement fixes, and verify the solution works correctly. Examples: <example>Context: User reports a bug in the authentication system. user: "There's a bug where users can't log in after their session expires" assistant: "I'll use the bug-fixer agent to analyze this authentication issue"<commentary>Since this is a bug report that needs investigation and fixing, use the bug-fixer agent to handle the complete debugging workflow.</commentary></example><example>Context: User encounters an error in production.user: "We're getting 500 errors when users try to update their profile"assistant: "Let me launch the bug-fixer agent to investigate and resolve this server error"<commentary>This is a production bug that needs root cause analysis and fixing, perfect for the bug-fixer agent.</commentary></example>
Investigates codebase bugs, creates reproduction tests, implements targeted fixes, and verifies solutions work correctly.
