dead-code

What it does

This skill enables AI agents to identify and remove unused, obsolete, or redundant code within software projects. It streamlines maintenance by automatically scanning repositories to find functions, variables, or files that are no longer referenced or executed.

When to use it

• Refactoring legacy codebases where documentation is missing or outdated.
• Reducing technical debt before deploying a new feature to production.
• Cleaning up projects after deleting specific modules or dependencies.
• Preparing code for performance optimization by eliminating bloat.

Key capabilities

• Automated detection of dead functions and variables.
• Identification of unused imports and dependencies.
• Removal of obsolete files from the project structure.
• Integration with continuous integration workflows for ongoing cleanup.

Example prompts

• "Scan my current repository and list all JavaScript functions that have never been called."
• "Remove any Python modules in this folder that are no longer imported by other scripts."
• "Identify unused CSS classes and delete them from the stylesheet to reduce file size."

Tips & gotchas

Ensure you back up your code before running automated deletion scripts, as false positives can inadvertently remove functional logic. This skill works best on projects with established build pipelines where execution paths are clear.
