Summary

Repren is a powerful command-line tool for batch renaming and refactoring files and content using regular expressions, now enhanced with Claude Skill support for intelligent code transformations.

Key features

• Batch file and content renaming using regex patterns
• Command-line interface for automation and scripting
• Support for complex search-and-replace operations
• Integration with Claude Skill for AI-assisted refactoring
• Written in Python for cross-platform compatibility

Use cases

• Refactoring codebases with consistent naming conventions
• Renaming multiple files and directories in bulk
• Updating configuration files and documentation
• Migrating projects with systematic text replacements
• Automating repetitive text transformation tasks

It is small, self-contained, self-documenting, and works on Python 3.10-3.14 with **zero runtime dependencies**. Essentially, it is a general-purpose, brute-force text file refactoring tool. **Coding agents:** point your agent at repren and it installs itself as a skill: > **Run `uvx repren@latest --help` and follow the instructions to install repren as a skill.** repren’s `--help` ends with the exact install commands. Once installed, the agent uses repren automatically for bulk refactors and renames. (See [Agent Use](#agent-use).) **Zero runtime dependencies.** Installing repren (or running `uvx repren@latest`) pulls in nothing but repren itself and the Python standard library, so there is no transitive dependency tree to audit or be compromised. It is a single file you can read end to end before trusting it. The dev-only tooling used to build and test repren (pytest, ruff, and so on) is never installed when you use it. For example, repren could rename occurrences of certain names in a set
