Add, archive, or browse the accounts in your chart

The chart you got from create_book is a starting point, not a ceiling. As your books grow, you'll need a new category — a second bank account, a new expense line, a vendor big enough to warrant its own code — and manage_accounts is where that happens. It also lists the full chart with codes, names, and types, which is how your assistant finds the accountId that categorize_transactions and post_journal_entry both need to do anything.

Adding an account is a two-step conversation by design: ask for it, and the assistant previews the code and name it would create — including a warning if that code is already taken — before anything is written. Only when you confirm does the account actually get created. The same pattern applies to archiving: nothing changes on the first pass, only on confirmation.

Archiving is deliberately not deleting. An archived account stops accepting new postings, but everything that was ever posted to it stays exactly where it was — on every report, in the general ledger, in history. You can unarchive it later if you decide you need it again. There is no way to delete an account outright, on purpose: an account with history behind it should never disappear and take that history with it.
