READlist_workspaces

Lists the companies this connection was granted, with the id to pass as workspace and the KvK number and IBAN ending where Neno has them. It answers about the connection itself, so it never asks which company.

Description for models

List the companies this connection can act on, with the id to pass as the workspace argument on other calls, and the Chamber of Commerce (KvK) number and account-number ending where we hold them. Use this when the user asks which companies you can see, or when you need to work out which company a document or a question belongs to before acting on it.

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

Arguments

None. Call it with an empty arguments object.

Result

text

Success. The answer as plain text in content[0].text.

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.
