## Author's description

Find and remove dead code - unused functions, imports, variables, and files

## Pairs well with

- [Duplicate code finder (/code-quality--dry)](https://skills.sgomez.dev/en/s/code-quality--dry.md): Scans your codebase for duplicated code, shows every location, and suggests a shared abstraction with refactored code, ranked by occurrences and risk.
- [Code complexity analysis (/code-quality--complexity)](https://skills.sgomez.dev/en/s/code-quality--complexity.md): Measures cyclomatic and cognitive complexity per function, flags those over the thresholds and suggests how to simplify them.
- [Code smell detection (/code-quality--code-smells)](https://skills.sgomez.dev/en/s/code-quality--code-smells.md): Scans code for smells and anti-patterns, reporting each one's location, severity and a concrete refactoring suggestion.
- [Code naming review (/code-quality--naming)](https://skills.sgomez.dev/en/s/code-quality--naming.md): Reviews variable, function and class names in your code and returns a table of current name, suggested name and the reason for each change.
- [Error handling review (/code-quality--error-handling)](https://skills.sgomez.dev/en/s/code-quality--error-handling.md): Audits how your code handles errors, finding swallowed errors, generic catches and poor messages, and suggests concrete improvements.
