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
# Paid Media Financial Model 1. Identify the decision and collect units, currency, period, tax/refund treatment, margin, attribution basis, and uncertainty. 2. Show the formula and map every input to an operator value or cited artifact. 3. Validate denominators, sign, missing values, incompatible windows, and unit conversions. 4. Calculate base, downside, and upside cases where uncertainty affects the decision. 5. Keep platform-attributed revenue, blended business revenue, cash flow, and contribution margin distinct. 6. Return machine-readable inputs, formulas, outputs, sensitivities, and decision implications. Never fabricate missing financial inputs, hide division-by-zero, or present a point forecast without its assumptions.

How to install
mdr add agricidaniel/claude-ads/ads-math@sha256:b129b371f983c8f4The line at the top of this page pins the label git:20260711.c346837, 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.
