Pull Request Title Rules

Pull request format must respect this format:

<type>(<scope>, <scope>...): <Notion ID> or "sentry" - <description>

Allowed types: feat, fix, refactor, chore.
Allowed scopes: release, app, admin, misc, api, all, github, terraform, kb, lib.

Notion ID, followed by a - is mandatory on types refactor, feat and fix.

If you really need to bypass the pull request title validation, you can add the bypass title label to you PR.

Examples of valid PR titles:

• chore(release): New version 1.3.3.7
• refactor(api): 1789 - Removed monarchy from codebase
• fix(api, app, admin): 1981 - User cannot delete each other accounts anymore.
• fix(api): sentry - Implement capture or fix a bug.
