Teams Messages
Overview
Use this skill to compose, rewrite, route, or send Teams messages. Apply it when the next step involves posting to a chat, replying in a thread, creating a new chat, starting a channel thread, or writing message text that could be sent later.
Workflow
- Identify the intended destination first: existing chat, new DM, new group chat, channel post, or thread reply.
- Determine from the request whether the user wants draft text or an actual send, and use the matching path.
- Resolve exact IDs before writing:
- teams or channels:
resolve_team, resolve_channel
- existing chats:
resolve_chat
- people for new chats or mentions:
resolve_user
- Use
validate_write_target when the destination is described in natural language and it is unclear whether the user means an existing target or a create-style action.
- Route to the correct write action:
- existing chat:
send_chat_message
- new DM or group chat:
create_chat, then send_chat_message
- new channel thread:
send_channel_message
- reply in an existing chat or channel thread:
reply_to_message or reply_to_channel_message
- new channel:
create_channel
Mention Rules
- Resolve people before writing when the message should tag someone.
- Use structured Teams mention inputs with exact Entra user IDs plus display names.
- Do not rely on plain
@name text to create a real Teams mention.
- If the target user cannot be resolved confidently, say so and return draft text without implying the mention will work.
Routing Rules
- For an existing direct conversation, prefer the existing two-person chat even if Teams labels it as
group instead of oneOnOne.
- For a new direct chat, call
create_chat(chat_type='oneOnOne') with exactly one resolved recipient user ID.
- If one-on-one creation fails with a caller-membership mismatch, fetch the caller profile and fall back to a two-person
group chat containing the caller and the intended recipient.
- For note-to-self requests, prefer an obvious existing self-chat target. If none is exposed, create a one-member
group chat containing only the caller and send the note there.
- For channel replies, prefer replying by canonical message path instead of inferring the target from quoted text alone.
Support Boundaries
- Teams drafts here are returned text only. There is no native persisted draft object.
- Do not claim support for Teams tags, reactions, file uploads, message edits, message deletes, or Slack-style canvases.
- Do not imply broad channel-notification behavior beyond what a normal Teams post or structured mention can do.
Output Conventions
- For drafts, return only the message text unless the user asked for explanation.
- For multiple routing candidates, present the smallest useful disambiguation rather than guessing.
- When a send is blocked, say whether the blocker is destination ambiguity, missing user resolution, or a Teams product rule.
