Use the commits hooks to achieve this
https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks#_committing_workflow_hooks

prepare-commit-msg

The prepare-commit-msg hook is run before the commit message editor is fired up but after the default message is created.

It lets you edit the default message before the commit author sees it.

This hook takes a few parameters: the path to the file that holds the commit message so far, the type of commit, and the commit SHA-1 if this is an amended commit.

This hook generally isn’t useful for normal commits; rather, it’s good for commits where the default message is auto-generated, such as templated commit messages, merge commits, squashed commits, and amended commits.

You may use it in conjunction with a commit template to programmatically insert information.
