Use this skill when a company needs to decide how much assessment each supplier deserves, or asks "tier our vendors", "which suppliers are critical", "we have 200 vendors and cannot assess them all", "build a third-party risk tiering", "rank suppliers by risk" or "which vendors need a security review this year". Builds the complete supplier population from finance, single sign-on and contracts, scores each supplier on data, access and dependency, assigns a tier by the highest axis, sets the…
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
Use this once to set up supplier risk management, then whenever a supplier is onboarded or its use changes. You get three files in a new folder, `./vendor-tiering/`: a spreadsheet you can open in Excel listing every supplier with its scores, tier and next review (`vendor-tiers.csv`), a one-page note on how the tiers are decided, short enough for an owner to apply alone (`tiering-method.md`), and the questions each business owner must answer to confirm their suppliers' scores (`questions-for-owners.md`). This skill drafts for a human to review and sign; this skill never marks a control effective. The tier is a proposal; the business owner of each supplier confirms it.

mdr add better-isms/grcskills/vendor-tiering@sha256:244aa848ee7c3e9eThe line at the top of this page pins the label git:20261027.690016c, 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.
