Why doesn't my post-checkout hook fire when creating a new worktree in a bare repository?

I want to run a post-checkout script whenever I git worktree add <branch> in my bare repository.

So far I've:

• bare cloned the git repo and cd'd into it.
• created hooks/post-checkout with a simple echo foo
• set chmod +x hooks/post-checkout
• run git worktree add master

However, the post-checkout hook isn't run... or at least my echo isn't visible.

Is there something I'm missing or misunderstanding?

Appreciate any help!

In this case, it was husky that was changing the git hooks dir in git config. It was enough to simply commit the post-checkout hook to the repo under .husky/
