Score a Microsoft 365 tenant's readiness for a Copilot rollout against Microsoft's oversharing checks and produce a fix list per site owner, from read-only exports of SharePoint sites, sensitivity labels, Everyone grants, sharing links and DLP policies. Use when asked "are we ready to turn on Copilot?", before a Copilot pilot or before it widens. Not for tenant guest settings alone (guest-and-external-sharing-review), reading file contents, or changing any permission.
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
# Copilot oversharing readiness Microsoft 365 Copilot answers from everything the signed-in user can reach. Sites shared with "Everyone except external users", files shared with anyone or organisation-wide links, sites with no sensitivity label and no owner, and no enforced DLP policy all turn quiet oversharing into answers on screen. Microsoft's Copilot deployment guidance asks for these to be found and fixed before rollout, site by site, with the owners. This skill exports those facts read-only, scores the tenant against the checks, and writes the remediation list grouped by site owner, as a draft for people to confirm. ## Read-only principle Export, evaluate offline, propose. Every export below is a read: PnP `Get-` cmdlets, Security and Compliance `Get-` cmdlets and Graph `GET` requests. The script reads the saved files and prints a report (and writes only to `--out` and `--csv` when given); it never connects to Microsoft 365 and never changes a permission, link, label or policy. Each fix is a portal path shown for review. A change runs only after the user confirms that exact change in the conversation, and the site owner should agree to it first. …

How to install
mdr add basitalisandhu/m365-governance-skills/copilot-oversharing-readiness@sha256:76cf8b0ef8c6e48aThe line at the top of this page pins the label git:20261018.90e09ac, 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.
