What types of code does this skill detect?

The skill detects unreachable code, unused imports, variables, and functions, large blocks of commented-out code, and legacy backward compatibility shims.

Does this skill automatically delete code?

No, it functions as an auditor that provides a detailed JSON report of findings and recommendations, allowing developers to make informed decisions about deletions.

Can it identify deprecated patterns?

Yes, it specifically greps for @deprecated JSDoc tags, 'legacy' naming conventions, and old version conditional logic to flag code that should be removed.

How does the scoring algorithm work?

It uses a weighted penalty system: high-severity issues (like old legacy shims) deduct 1.0 points, medium issues (unused functions) deduct 0.5, and low-severity issues (unused imports) deduct 0.2 from a base score of 10.

Developer Tools

Identifies and audits unreachable code, unused variables, and legacy shims to reduce technical debt and codebase bloat.

The Dead Code Auditor is a specialized L3 worker designed to streamline codebase maintenance by locating unused or unreachable code. It systematically scans for dead imports, abandoned functions, commented-out blocks, and outdated backward compatibility shims that often bloat modern repositories. By providing a structured compliance score and detailed JSON findings, it helps developers prioritize refactoring efforts and maintain a lean, high-performance codebase within a larger automated delivery pipeline.

Key Features

01Scans for legacy backward compatibility shims and deprecated migration patterns

02Detects unreachable code patterns after return, throw, or break statements

03Analyzes and flags large blocks of commented-out code using grep patterns

04Identifies unused imports, variables, and functions using linter-based logic

05Generates a quantitative compliance score and detailed JSON report for automated workflows

Use Cases

01Improving codebase maintainability by removing unused 'dead weight' before refactoring

02Automating technical debt reviews during high-level project quality gates

03Cleaning up legacy adapters and shims after a successful system migration
