Tell HN: Do not include co-authored-by Claude in your commits

By including co-authored-by claude you are helping AI companies to exclude it from their training set.

Make sure you don't include Claude contributions in the commit messages, if model is so good, they should dogfood and use it for training their models

They can automatically determine which are their own model outputs anyway by comparing the code to their internal logs

Are they practically doing this ?

When it comes to data quality it justifies a few checks.

Seems impractical

Generally, it's automatically included when Claude Code makes a commit.

You can just add the following to ~/.claude/settings.json

"alwaysThinkingEnabled": true, "includeCoAuthoredBy": false, "gitAttribution": false

You can always configure it per ^^^. And anyone can search by that flag as well so eitherway it should be a good practice.
