Claim-level verification of any report or data set — extract every figure and factual claim, check each against a primary source (SEC filing, company IR, FRED, exchange data, or the user's own document), recompute derived numbers, mark ✅ verified / ⚠️ mismatch / ❓ unverifiable, and re-issue the report with inline citations and a References section; Verification Score 0–10.
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
# Fact Check — Verify the Numbers, Cite the Sources ## ⚠️ Data Verification — Do This Before Any Analysis Before verifying anything, establish what data each claim actually needs: 1. **Fetch current price only where a claim needs it** — market claims (price, market cap, yield, multiples "today") are checked against a live quote for the report's as-of date and today's; use web search or ask the user. Reported figures, historical comparisons, and `--recompute` runs need **no** live quote — do not request one, and do not let its absence block them. Never assume a price from training data. 2. **Confirm key figures** — for this skill the "key figures" are the *sources themselves*: the filing (10-K / 10-Q / 8-K / proxy / Form 4 / 13F), the IR release, the FRED series, the exchange or issuer data, or the document the user pasted. Retrieve or request them before judging a single claim. A claim checked against memory is not checked. 3. **State your data source** — fill in the `Data & Sources` header (next section) so the origin, as-of date, retrieval path, and confidence of every figure are explicit at the top of the output. …

How to install
mdr add yennanliu/investskill/fact-check@sha256:2879fb3d1c5a9723The line at the top of this page pins the label git:20261024.1726f29, 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.
