/code-quality--error-handling

Finds unused imports, variables, functions, files and dependencies, verifies each finding and only removes code after you confirm.

Scans your codebase for duplicated code, shows every location, and suggests a shared abstraction with refactored code, ranked by occurrences and risk.

Measures cyclomatic and cognitive complexity per function, flags those over the thresholds and suggests how to simplify them.

Scans code for smells and anti-patterns, reporting each one's location, severity and a concrete refactoring suggestion.

Reviews variable, function and class names in your code and returns a table of current name, suggested name and the reason for each change.

Refactors the code you point to for quality without changing its behavior, explaining each change with a before and after.

Reviews your changed files or the ones you name, rating issues in correctness, security, performance and maintainability by severity with fix suggestions.

Adds or fixes type annotations in TypeScript/JavaScript and Python code without changing how it behaves at runtime.

Analyzes async/await, promise and concurrency code to find swallowed errors, ordering issues and deadlocks, and proposes the fix.

Builds a three-tier breakpoint plan with file, line, condition and what to check, so you can locate a specific bug quickly.

Stress-tests code with extreme inputs and simulated failures, writes tests per scenario, and rates the bugs it finds by severity.
