Skills

This plugin provides 8 skills that teach Claude about Microsoft 365:

Skill	Description
`calendar`	Exchange Online calendars through Microsoft Graph: event retrieval and date-range queries, free/busy and availability lookup, meeting and Teams-meeting creation, room and equipment resource bookings, calendar permissions, and the Graph scopes and error causes involved.
`files`	OneDrive personal storage and SharePoint document libraries, both reached through the shared Microsoft Graph `/drives` endpoint: drive and item addressing, sharing permissions, storage quotas, file search, and the offboarding file-transfer workflow.
`licensing`	The M365 subscription → SKU → service-plan model, seat availability versus consumption, assigning and removing licenses through Graph, the audit workflow for finding unused or misallocated seats, common SKU GUIDs, and licensing error causes.
`mailboxes`	Exchange Online mailboxes through Microsoft Graph: the four mailbox types and how they differ, message listing and search, inbox rules, out-of-office and forwarding, mailbox size and quota, shared-mailbox access management, and mail flow diagnostics.
`security`	The M365 tenant security checks that distinguish a secure tenant from a vulnerable one: per-user authentication-method inspection for real MFA enrollment, sign-in risk and risky users, suspicious inbox rules, legacy authentication exposure, conditional access coverage, Secure Score, and the indicator set for a compromised account.
`teams`	Microsoft Teams through Microsoft Graph: the Team/Channel/Member/Meeting/Tab object model, team and channel enumeration, membership and ownership changes, online meetings, usage reporting, and the causes behind Teams access failures.
`users`	The Entra ID user object as M365's central identity: key properties and their MSP relevance, account status values, the license assignment model, Graph patterns for listing/searching/creating/disabling users, MFA status checking, and the onboarding and offboarding sequences.
`api-patterns`	Microsoft Graph fundamentals shared by every M365 skill: Entra token scopes and the per-request Bearer model, OData query operators and filter syntax, @odata.nextLink pagination, delta queries for incremental sync, 429 throttling and retry behavior, JSON batching, and the common Graph error codes.

Agents

This plugin provides 2 agents for autonomous task execution:

Agent	Description
`identity-auditor`	Use this agent when an MSP needs to perform a comprehensive Microsoft 365 tenant security audit.
`license-auditor`	Use this agent when an MSP needs to audit Microsoft 365 license costs and find savings opportunities across a client tenant.
