Independently check AI-generated calculations using source inputs, formulas, and a calculator or spreadsheet.
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
# Double-Check AI Math Manually (Deterministic Verification) (AI Skill) ## Overview Because Large Language Models are probabilistic language generators rather than algebraic engines, they can generate an impeccable financial breakdown where the individual line items look flawless, but the **sum at the bottom is subtly wrong by $150 or 2.5%**. The **3-Tier Math Verification Ladder** provides a safety net to ensure that no AI-generated financial quote, invoice, equity cap table, or budget is delivered without deterministic proof of accuracy. --- ## The 3-Tier Math Verification Ladder ``` ┌─────────────────────────────────────────────────────────────┐ │ 3-Tier Math Safety Ladder │ │ │ │ [ TIER 1: AI Formula Derivation ] │ │ • Define variables, logic, and standard formulas │ │ │ │ │ ▼ │ │ [ TIER 2: Code / Python Execution ] │ │ • Force the AI to execute Python math programmatically │ …

How to install
mdr add alivirgo/major-ai-skills/double-check-ai-math-manually@sha256:f52e7224d7b58847The line at the top of this page pins the label git:20260911.25436b5, 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.
