Description for models

Send a draft invoice that create_invoice made: Neno assigns its invoice number and emails it to the customer's address on file. Neno asks the user to confirm the send directly; you cannot confirm it for them. If the reply says this app cannot show that confirmation, tell the user to send it from the Neno app.

Sent verbatim in tools/list. It's written for the model, so it says when to use the tool.

The invoice id that create_invoice returned.

Added by the server

On every tool that acts on one company
workspacestring

The id of the company this applies to. This connection covers a single company, which is filled in for you, so you can leave this out.

Result

text
Success. The answer as plain text in content[0].text, starting with Company: and the company name.
isError
Refused or failed. A missing permission, an invalid argument or a server failure sets isError: true. The text says what went wrong and what to tell the user.
input
Company needed. With several companies and no workspace argument, the server asks which company the call is for. A client that can't ask gets an error that lists the companies.
