Builds and stress-tests financial models for forecasting, scenario planning, and decision support — revenue build, cost structure, driver logic, and the sensitivities that show where a plan breaks. Use this to model a decision's financial consequence, build a forecast or long-range plan, evaluate an investment or hire, or pressure-test someone else's model before relying on it.
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
# Financial modeling A model is an argument about how the business works, expressed in arithmetic. Its value is the argument, not the output precision. ## Structure Three separated layers, always: 1. **Inputs** — every assumption, in one place, each with a source and a date. An assumption buried inside a formula is invisible and therefore never challenged. 2. **Calculations** — no hard-coded numbers. Ever. A constant inside a formula is an untraceable assumption. 3. **Outputs** — the statements and the summary a decision-maker actually reads. One row, one calculation, carried consistently across periods. Models become unauditable through inconsistent rows more than through complexity. ## Build revenue from drivers Never grow a top-line by a percentage. Build it: volume × price, or accounts × retention × expansion. Driver-based models can be argued with, and being argued with is the point — a growth rate cannot be wrong, only optimistic. Cost structure separated into fixed, variable, and step-fixed. The step-fixed items are where plans break, because they move in jumps nobody modeled. ## Sensitivities are the deliverable …

How to install
mdr add cbrock84/headcount/financial-modeling@sha256:5cb3faae39fac46fThe line at the top of this page pins the label git:20260916.0e7cd01, 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.
