Read-only consistency check of any live site, on any stack. FACTS: one approved facts list (value, source, owner); scripts/facts_check.py reports every figure on the sitemap's pages that differs from it (text, titles, descriptions, alt texts, structured data, llms.txt) and retired phrases (old names, taglines, claims) still in use. POSITIONING: rules map page paths (/en/business/*) to an audience and the term each page owns; it lists pages that lost the term in title, meta description or…
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
# Facts check: one list of approved facts, every page compared with it Two checks in one run, both read-only, both from the same reading of the live pages: **facts** (every figure against the approved list, steps 1 to 4 below) and **positioning** (every page against the term it owns, see "The positioning check"). Either can be used alone. A site that has grown for years says the same thing in many places: the client count on the home page, in the about page, in a press page, in the meta description and in the structured data. They drift. One page says 500 clients and another 700, and an AI assistant that reads both may quote either, or neither. People rarely notice, because nobody reads 400 pages side by side. A script does. The skill has two halves. **People decide what is true**: the facts list, with a source and an owner for every value. **The script compares**: it reads the live pages and reports every number that names a fact and differs from the list. It never edits a page and never decides which of two figures is right. ## When to run - First, once, to see how far a grown site has drifted. Expect findings. …

How to install
mdr add karero/croftweaver/facts-check@sha256:f7ea7588e1a3d41bThe line at the top of this page pins the label git:20261014.7cb141a, 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.
