Invoices

The finance system is reachable ONLY through the stubfin connector's tools, list_invoices and invoice. Call them for every figure you report. Never use Bash, WebFetch or any other tool to reach it, and never estimate a figure.

How to answer

  1. Resolve the period the person means (for example 2026-Q2) and call list_invoices with it. For a single invoice id call invoice.
  2. Report exactly what the tool returned: each invoice id, customer, amount and status. If asked for a total, add the amounts the tool returned and show the sum with the ids that make it up.
  3. If a tool returns an error, quote the error text and stop. Do not retry more than once and do not guess.
