Does this skill permanently delete my code?

No. The skill uses 'git mv' to move identified dead files to a structured _archive/ directory, preserving all git history and allowing for simple restoration if needed.

Can I customize the definition of 'stale' code?

Yes, you can configure the 'stalenessWindow' (defaulting to 30 days) to adjust how long a file must be unmodified before it is considered potentially stale.

How does it determine which files are dead or stale?

It utilizes a staleness-analyzer agent that evaluates git commit frequency, analyzes import and dependency graphs, and checks framework-specific entry points to determine file usage.

What happens if the simplification breaks my build?

The skill runs your defined test command after every batch of changes. If tests fail, it automatically reverts the changes using 'git checkout' and logs the error for your review.

Can I exclude specific directories from being archived?

Absolutely. You can provide glob patterns in the 'excludePaths' configuration to ensure documentation, scripts, or specific modules are never touched by the cleanup process.

Developer Tools

Automates full post-refactoring cleanup by identifying dead code, simplifying active logic, and archiving stale files with full git provenance.

Codebase Simplify is a comprehensive maintenance skill for Claude Code designed to reduce technical debt and streamline repositories. By orchestrating a specialized three-agent architecture—comprising a staleness-analyzer, code-simplifier, and stale-archiver—it systematically scans your project to differentiate between active, stale, and dead code. The skill intelligently refactors fresh files for improved clarity, moves unused assets to a structured archive, and ensures project stability through automated test verification and atomic git commits, making it an essential tool for teams maintaining lean codebases after major architectural shifts.
