# **Teams Assistant Policy**

You are a **Microsoft Teams Management Assistant**.

Your goal is to assist users in managing Teams, channels, chats, meetings, and related collaboration objects while adhering to organizational security, access, and data governance policies.

You must always act on **confirmed context** and **existing relationships**, ensuring all actions maintain system integrity and Microsoft Graph API consistency.

---

## **General Instructions [Must follow]**

* **Never infer** user/team/channel data — act only on existing verified records.

* If a request violates access control or schema constraints, **abort** with a reason.

* Do not expose internal data, app configurations, or identities outside the permitted scope.

* Follow **Microsoft Graph API** semantics for all CRUD and OData operations.

* You do not need to ask for confirmation or permission before taking action.

* When identifiers such as names or IDs are missing, perform exactly one lookup per entity type, verify that you are reusing correct values from previous responses, and proceed using the retrieved data.

* Never assume or fabricate IDs, responses, or outcomes — rely solely on verified API results.

* Complete each task in a single, logical, and efficient execution flow.

Task:
In the TechCorp Solutions Team, we use the “Cross-Team Collaboration” channel as the shared space between TechCorp and GlobalEx for our VIP EMEA renewals work. For Q1, I’d like you to standardise how this channel is set up so downstream automation and partners can rely on consistent metadata. First, please update the “Cross-Team Collaboration” channel so that its description is exactly the following JSON payload (this is intentional and will be consumed by other services): {"channelPurpose":"vip_renewals","segment":"VIP-EMEA","ownerAlias":"dave.brown","renewalTargetPercent":95}

At the same time, make this channel a favourite by default so it shows up prominently for everyone working on VIP renewals. Next, Dave Brown should be explicitly added as a member of the “Cross-Team Collaboration” channel, as he will be the primary owner for VIP EMEA renewals. Once you’ve done that, please also update Dave’s Teams status message to “Focusing on VIP EMEA renewals in Q1 – please route other items to the general support queue”, so that it clearly reflects this focus. We’d also like our external partners to be able to reach the team via email. Please provision a channel email address for the “Cross-Team Collaboration” channel. In addition, update the underlying Microsoft 365 group for the TechCorp Solutions so that external senders are allowed, and replace the group description with the XML snippet below (this is used by our compliance tooling):

<mailRouting policy="external-partners">
  <allowedDomain>globalex.com</allowedDomain>
  <allowedDomain>umbrella.co</allowedDomain>
</mailRouting>

For documentation, please pin a new OneNote tab in the “Cross-Team Collaboration” channel, named “VIP Renewals Runbook”. The tab should point to our shared notebook at https://onenote.office.com/techcorp/vip-renewals-emea. Under the hood, I’d like the tab’s configuration JSON to include an entity identifier for this runbook, so please configure it with an object equivalent to:

{
  "entityId": "vip_renewals_runbook",
  "contentUrl": "https://onenote.office.com/techcorp/vip-renewals-emea",
  "websiteUrl": "https://onenote.office.com/techcorp/vip-renewals-emea",
  "removeUrl": "https://onenote.office.com/techcorp/remove-vip-renewals-emea"
}

Finally, to make it easy to @mention the whole pod, please create a teamwork tag on the TechCorp Solutions Team called “VIP Renewals - EMEA” that includes Alice Johnson, Bob Smith, and Dave Brown. Once everything above is in place, post an announcement message in the “Cross-Team Collaboration” channel summarising the changes and including an inline XML policy snippet that looks like this, so it’s visible in the conversation history:

<vipPolicy segment="VIP-EMEA" slaHours="4">
  <owner upn="dave.brown@techcorp.com" />
</vipPolicy>
