Use this agent when code changes have been made and you need to write new tests, run existing tests, analyze failures, and fix them while maintaining test integrity. This agent should be triggered proactively after code modifications to ensure comprehensive test coverage and suite health. Examples: <example> Context: The user has just implemented a new feature or modified existing code. user: "I've updated the user authentication logic to support OAuth" assistant: "I've successfully updated the authentication logic. Now let me run the test-writer-fixer agent to ensure all tests pass with these changes." <commentary> Since code changes were made, use the Task tool to launch the test-writer-fixer agent to run relevant tests and fix any failures. </commentary> </example> <example> Context: The user has refactored a module or changed function signatures. user: "Please refactor this payment processing module to use async/await" assistant: "I've completed the refactoring to use async/await throughout the payment module." <function call omitted for brevity> assistant: "Now I'll use the test-writer-fixer agent to run the tests and fix any issues caused by the refactoring." <commentary> After refactoring code, proactively use the test-writer-fixer agent to ensure tests still pass. </commentary> </example> <example> Context: The user has fixed a bug or made a critical change. user: "Fix the race condition in the data synchronization service" assistant: "I've identified and fixed the race condition by implementing proper locking mechanisms." <function call omitted for brevity> assistant: "Let me run the test-writer-fixer agent to verify the fix doesn't break existing functionality." <commentary> After bug fixes, use the test-writer-fixer agent to ensure the fix works and doesn't introduce regressions. </commentary> </example> <example> Context: Code lacks test coverage for critical functionality. user: "Our payment processing module has no tests" assistant: "That's a critical gap. Let me use the test-writer-fixer agent to create comprehensive tests for the payment module including edge cases and error scenarios." <commentary> Critical modules without tests are high-risk areas that need immediate test coverage. </commentary> </example> <example> Context: After implementing a new feature that needs tests. user: "I've added the social sharing functionality" assistant: "Great! The social sharing is implemented. Now let me use the test-writer-fixer agent to write tests that ensure this feature works correctly across different platforms." <commentary> New features should always include comprehensive test coverage from the start. </commentary> </example>

Use this agent when you need to review code for adherence to project guidelines, style guides, and best practices. This agent should be used proactively after writing or modifying code, especially before committing changes or creating pull requests. It will check for style violations, potential issues, and ensure code follows the established patterns in CLAUDE.md. Also the agent needs to know which files to focus on for the review. In most cases this will recently completed work which is unstaged in git (can be retrieved by doing a git diff). However there can be cases where this is different, make sure to specify this as the agent input when calling the agent. Examples: <example> Context: The user has just implemented a new feature with several TypeScript files. user: "I've added the new authentication feature. Can you check if everything looks good?" assistant: "I'll use the Task tool to launch the code-reviewer agent to review your recent changes." <commentary> Since the user has completed a feature and wants validation, use the code-reviewer agent to ensure the code meets project standards. </commentary> </example> <example> Context: The assistant has just written a new utility function. user: "Please create a function to validate email addresses" assistant: "Here's the email validation function:" <function call omitted for brevity> assistant: "Now I'll use the Task tool to launch the code-reviewer agent to review this implementation." <commentary> Proactively use the code-reviewer agent after writing new code to catch issues early. </commentary> </example> <example> Context: The user is about to create a PR. user: "I think I'm ready to create a PR for this feature" assistant: "Before creating the PR, I'll use the Task tool to launch the code-reviewer agent to ensure all code meets our standards." <commentary> Proactively review code before PR creation to avoid review comments and iterations. </commentary> </example>
