Thin wrapper adapters + SKILL.md for Slack, Telegram, GitHub, Linear,
Google Chat, Teams, WhatsApp Cloud API, Resend, Matrix, Webex, iMessage.
All follow the same pattern as discord-v2.ts: readEnvFile → create*Adapter
→ createChatSdkBridge → registerChannelAdapter.

+
+# Add Microsoft Teams Channel (v2)
+
+This skill adds Microsoft Teams support to NanoClaw v2 using the Chat SDK bridge.
+
+## Phase 1: Pre-flight
+
+Check if `src/channels/teams-v2.ts` exists and the import is uncommented in `src/channels/index.ts`. If both are in place, skip to Phase 3.
+
+## Phase 2: Apply Code Changes
+
+### Install the adapter package
+
+```bash
+npm install @chat-adapter/teams
+```
+
+### Enable the channel
+
+Uncomment the Teams import in `src/channels/index.ts`:
+
+```typescript
+import './teams-v2.js';
+```
+
+### Build
+
+```bash
+npm run build
+```
+
+## Phase 3: Setup
+
+### Create Teams Bot
+
+> 1. Go to [Azure Portal](https://portal.azure.com) > **Azure Bot** > **Create**
+> 2. Fill in the bot details and create
+> 3. Go to **Configuration**:
+>    - Messaging endpoint: `https://your-domain/webhook/teams`
+> 4. Go to **Channels** > add **Microsoft Teams**
+> 5. Note the **Microsoft App ID** and **Password** (from the bot's Azure AD app registration)
+
+### Configure environment
+
+Add to `.env`:
+
+```bash
+TEAMS_APP_ID=your-app-id
+TEAMS_APP_PASSWORD=your-app-password
+```
+
+Sync to container: `mkdir -p data/env && cp .env data/env/env`
+
+### Build and restart
+
+```bash
+npm run build
+launchctl kickstart -k gui/$(id -u)/com.nanoclaw  # macOS
+# systemctl --user restart nanoclaw  # Linux
+```
+
+## Phase 4: Verify
+
+> Add the bot to a Teams channel or send it a direct message. The bot should respond within a few seconds.
+
+## Removal
+
+1. Comment out `import './teams-v2.js'` in `src/channels/index.ts`
+2. Remove `TEAMS_APP_ID` and `TEAMS_APP_PASSWORD` from `.env`
+3. `npm uninstall @chat-adapter/teams`
+4. Rebuild and restart
