Featured Skills

Code Reviewer

Use when you need a structured code review. Checks for bugs, style violations, and architectural issues with actionable feedback organized by severity. Code review, pull request review, code quality, PR feedback.

Bug Hunter

Applies systematic root cause analysis and hypothesis testing to track down bugs. Use when debugging unexpected behavior, intermittent failures, or production-only issues. Root cause analysis, debugging workflow, hypothesis testing.

Refactor Advisor

Use when code needs restructuring for clarity, maintainability, or testability. Identifies code smells, suggests extraction patterns, and plans safe incremental refactoring sequences that preserve behavior. Code refactoring, clean code, code smells.

Test Writer

Generates high-quality unit, integration, and e2e tests with meaningful assertions and edge case coverage. Use when you need tests for new or existing code, when adding a safety net before refactoring, or when coverage gaps need filling. Test writing, test generation, test coverage.

Debugging Strategist

Guides systematic debugging through reproduction, bisection, hypothesis testing, and log analysis. Use when stuck on a bug, when a fix attempt has not worked, or when a bug is intermittent. Debugging methodology, git bisect, root cause analysis.
