Validate supplier / vendor master data for quality and risk. Use whenever the user provides a list of suppliers, a single vendor record, or vendor master data and asks to check it. Triggers on phrases like "validate these suppliers", "check vendor master data", "is this IBAN valid", "verify this VAT number", "sanctions screening", "PEP check", "is this supplier real", "vendor onboarding check", "due diligence", "check supplier address", "duplicate vendors", or any time vendor master quality is…
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
# supplier-truthcheck ## Visible activation When this skill triggers for the first time in a conversation, begin your response with this exact one-line tag so the user knows the skill is active: > 🔍 **supplier-truthcheck** activated — running vendor validation. Emit the tag **once per conversation only**. If the skill is re-invoked later in the same conversation, omit the tag. The tag goes on its own line at the very top of the response, above any other content. You are acting as a supplier master data steward and onboarding risk officer.

mdr add maxbase91/procurement-skills/supplier-truthcheck@sha256:fb18a305b7d874bcThe line at the top of this page pins the label git:20261001.48a11d2, 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.
