I'm unsure what it's supposed to achieve.

I know typos very well.

I see two problems here:

• you're calling typos without -w
• typos might suggest multiple solutions to fix a typo. So -w won't fix it. You will have to fix it manually, and typos will return an non-zero exist code, which may be interpreted wrongly by your tool
