Can I use it to request leave?

Yes! The tool has specialized handling for leave requests. Simply state that you are taking leave, and it will automatically log a full day.

What kind of reports can I generate?

You can generate time reports by project, client, task, or team member. Reports can cover custom time periods like 'last month' or 'this week'.

What credentials does it need?

It reads `HARVEST_ACCESS_TOKEN`, `HARVEST_ACCOUNT_ID` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
