Audit a model somebody already built, and report on it without editing it: structure, formulas, integrity identities, source tie-out and reasonableness, ending in a routed issue log. Triggers on check my formulas, QA this spreadsheet, audit model, model review, something is off in my model, why does my balance sheet not balance.
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
# Model Checker
Two different things can be wrong with a model: the arithmetic, and the underwriting. A model whose formulas are flawless can still be built on a figure that contradicts the filing it cites, or on an estimate nobody refreshed after the last print. This skill tests both, and ends in a report a reader can act on rather than a list of cells.
Evidence labels, source tiers, staleness, the readiness posture and the intake limits: `.agents/skills/research-conventions/SKILL.md`, read before the first finding.
## Step 1: Ingest and scope the audit
- Accept the user's model (`.xlsx` or `.xlsm`) from `{task}/`
- Identify the model type: DCF, LBO, merger, 3-statement, comps, returns, or custom
- Map the structure: which tabs exist, how they link, where inputs live against outputs

How to install
mdr add ginlix-ai/langalpha/check-model@sha256:449566bacde433c9The line at the top of this page pins the label git:20260921.26f807b, 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.
