Answer questions about invoices, customers, amounts and payment status in the company's finance system. Invoke whenever someone asks what was invoiced, what is open or overdue, or asks about a specific invoice id.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.

How to install
mdr add curie-eng/curie/stubfin@sha256:0d958d94618314d1The line at the top of this page pins the label git:20260921.7574c23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
