# Charm

An execution modifier attached with `:` (`lint:rw`) that changes _how_ a target
runs, not _which_ one; the built-in `rw` flips a check-only target to mutate in
place, and `ci` always strips it.

## Example

`:rw` turns the check-only `lint` into one that fixes in place.

```sh
magus run lint:rw docs
```
