This skill should be used when several customers, organizations, teams or workspaces share one application and their data must stay apart — and especially when a person can belong to more than one of them.

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
# Multi-tenancy Tenant isolation is one rule — "you only touch what belongs to an organization you are in" — that must hold in every query, every server function and every screen. This skill is about writing that rule **once** and about the places it is forgotten. Analogy: an office building with several companies. The lobby is shared, each floor is private.

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.
