# Pre-Modification Check with Repowise

Look before you touch a file other things depend on

## What this does

Shared utilities and core modules are the ones where a small edit turns into a wide breakage. This runs a check before you modify, move, refactor or delete a file, so you find out what it touches first. Reach for it especially when the file was not one you set out to change.

### Top 3 things it does for you

- Check what a file is used by before editing it
- Look before moving or deleting a shared utility
- Check the reach of a change to a public API
