Add Microsoft Teams Channel

Adds Microsoft Teams support via the Chat SDK bridge — interactive chat in team channels, group chats, and direct messages. NanoClaw doesn't ship channels in trunk — this skill copies the Teams adapter in from the channels branch.

The mechanical steps under Apply carry nc: directive fences: an agent reads the prose and applies them, and a parser can apply them deterministically from the same document. Every directive is idempotent, so the whole skill is safe to re-run; anything a parser can't apply falls back to the prose beside it.

Teams has no "paste a token" shortcut — a bot has to exist in Microsoft's cloud before it can receive a message. The Microsoft Teams CLI collapses that into one sign-in and one create command: it registers the Entra app, generates the client secret, registers a Teams-managed bot (through the Teams Developer Portal — no Azure subscription needed), uploads the app package, and hands back an install link. The old ~7-step Azure portal walk survives only as a fallback in Alternatives for tenants where the Developer Portal is blocked.

Apply

1. Copy the adapter and its registration test

Fetch the channels branch and copy the Teams adapter and its registration test into src/channels/ (overwrite — the branch is canonical):

src/channels/teams.ts
src/channels/teams-registration.test.ts

2. Register the adapter

Append the self-registration import to the channel barrel (skipped if the line is already present). This one line is the skill's only reach-in into core:

import './teams.js';

3. Install the adapter package

Pinned to an exact version — the supply-chain policy rejects ranges and latest:

@chat-adapter/teams@4.29.0

4. Build and validate

Build first: it guards the typed createChatSdkBridge(...) core call and proves the dependency is installed. Then run the one integration test.

pnpm run build

pnpm exec vitest run src/channels/teams-registration.test.ts

teams-registration.test.ts imports the real channel barrel and asserts the registry contains teams. It goes red if the import line is deleted or drifts, if the barrel fails to evaluate, or if @chat-adapter/teams isn't installed (the import throws) — so it also covers the dependency from step 3. End-to-end delivery against a real Teams workspace is verified manually once the service runs.

Credentials

The adapter is installed and registered, but it can't receive a message until a bot exists, points at this machine, and is installed into Teams. The Teams CLI does all of that below.

Check for existing credentials

Re-running teams app create provisions a brand-new app registration and bot each time — it never reuses the first one. So the flow starts with a probe: when .env already carries a Teams credential — either key; a partial pair means a half-finished setup that creating ANOTHER app would only corrupt — every step below (prompts included) is skipped and the flow drops straight through to Restart. To rotate credentials or finish a partial configuration, see Troubleshooting; if your tunnel URL changed, the fix is teams app update, not a re-run (also in Troubleshooting).

( grep -q '^TEAMS_APP_ID=.' .env 2>/dev/null || grep -q '^TEAMS_APP_PASSWORD=.' .env 2>/dev/null ) && echo yes || echo no

Before creating anything, tell the user:

Confirm you have everything Teams setup needs:
1. A Microsoft 365 account that can create Entra app registrations and upload custom apps (sideloading) — free personal Teams does NOT qualify; you need a Microsoft 365 Business / EDU / developer tenant.
2. A way to expose an HTTPS endpoint that forwards to this machine's webhook port 3000 (e.g. a Cloudflare Tunnel, or a reverse-proxied VPS). Start it now if it isn't running — e.g. `cloudflared tunnel --url http://localhost:3000` — the create step needs the URL up front. The next prompt asks for its public base URL: just the https:// origin, no trailing path.
Note: the bot is created single-tenant (only your own Microsoft 365 tenant can install it) — the right default for a self-hosted assistant. If you need a bot other tenants can install, set it up manually via the Alternatives section of this skill instead.

Public URL

Microsoft delivers bot messages to an HTTPS endpoint you control; it has to reach this machine's webhook server (port 3000, configurable via WEBHOOK_PORT) at /webhook/teams.

Paste your tunnel's public https:// URL — e.g. https://your-tunnel.trycloudflare.com

App name

One more choice belongs to the human before anything is created. The name is used everywhere at once: the Entra app registration, the bot, and the Teams app are all created under it. There is no client-secret name to pick on this path — the CLI generates the secret itself (Entra displayName default, 2-year expiry); rotating it later is in Troubleshooting.

What should the bot be called? One name covers the Entra app registration, the bot, and the Teams app (letters, digits, spaces, . _ -; max 30 characters) — e.g. NanoClaw.

Install the Teams CLI

Installed globally with npm — not as a workspace dependency — deliberately: the CLI's credential store (keytar) is a native module whose install script must run to fetch its prebuilt binary, and pnpm's supply-chain policy blocks dependency build scripts — a workspace install leaves the sign-in unable to persist. The global install matches Microsoft's own instruction and keeps the workspace policy intact. Pinned; re-running is a no-op. (If npm reports EACCES here, your global prefix needs root — prefer a user-level Node like nvm, or npm config set prefix ~/.npm-global.) --loglevel=error because npm runs inside a pnpm script here and warns about every pnpm config var it inherits — pure noise; real errors still print.

npm install -g @microsoft/teams.cli@3.0.2 --loglevel=error

npm's global bin directory is not reliably on PATH (custom prefixes rarely are), so every step below calls the CLI by its absolute path, $(npm prefix -g)/bin/teams (stderr of the prefix lookup silenced — same pnpm-config noise as above). Where this document says to run teams … by hand, use that path too if plain teams isn't found.

Sign in to Microsoft 365

Every teams command is a separate process, so the sign-in must survive into the next one via the CLI's on-disk token cache. A "libsecret not found — token cache will be stored unencrypted" warning here is safe to ignore: the CLI falls back to a plaintext cache file that persists fine, and setup signs the session out at the end anyway. The login output may also report "Azure CLI: not installed" — informational only; this flow creates a Teams-managed bot precisely so the Azure CLI is never needed (it only matters for --azure bots and the manual portal path). The step below verifies persistence by re-reading the session from a fresh process after login. In an interactive terminal the login opens a browser; on a headless box (SSH) it prints a device code — open microsoft.com/devicelogin on any machine and enter it. If this step fails, run teams login then teams status by hand: status must say logged in, or the cache is not persisting (see Troubleshooting).

"$(npm prefix -g 2>/dev/null)/bin/teams" login && "$(npm prefix -g 2>/dev/null)/bin/teams" status --json 2>/dev/null | grep -q '"loggedIn": true' && printf '=== NANOCLAW SETUP: TEAMS-LOGIN ===\nSTATUS: success\n=== END ===\n'

Create the bot

One command registers the Entra app, generates a client secret (Graph can take ~30s to see the new app — the CLI retries), registers a Teams-managed bot, and uploads the app package to the Teams Developer Portal. It needs the sign-in from the previous step (AUTH_REQUIRED means run that first). The bot is always created single-tenant (--sign-in-audience myOrg) — the right default for a self-hosted assistant, applied without asking; for a bot other Microsoft 365 tenants can install, set it up manually per Alternatives.

"$(npm prefix -g 2>/dev/null)/bin/teams" app create --name "{{app_name}}" --endpoint "{{public_url}}/webhook/teams" --sign-in-audience myOrg --json

Store the credentials

The adapter reads these from .env (set-if-absent — a value you've already filled in is never overwritten). The pairing matters: SingleTenant requires TEAMS_APP_TENANT_ID, and a multi-tenant app must instead set TEAMS_APP_TYPE=MultiTenant with no tenant ID — a mismatch makes the adapter authenticate against the wrong authority and every message fails with a 401 from Bot Framework.

TEAMS_APP_ID={{app_id}}
TEAMS_APP_PASSWORD={{app_password}}
TEAMS_APP_TENANT_ID={{app_tenant_id}}
TEAMS_APP_TYPE=SingleTenant

Set the app icons

The CLI-created app ships with placeholder icons; this swaps in the NanoClaw mascot (the same PNGs the manual-path package bakes into its zip), so the install dialog below already shows it. Cosmetic — a failure is logged and skipped, never blocking setup. Re-runnable any time while signed in to the Teams CLI:

"$(npm prefix -g 2>/dev/null)/bin/teams" app update {{teams_app_id}} --color-icon setup/assets/teams/color.png --outline-icon setup/assets/teams/outline.png --json || echo "Icon update failed — cosmetic only, continuing."

Who owns this bot

The account signed into the Teams CLI is the account that just created the bot — that human is the wiring target this flow suggests. Its identity comes from the CLI session, so this runs before the sign-out step below:

"$(npm prefix -g 2>/dev/null)/bin/teams" status --json 2>/dev/null

Confirm the wiring target

Nothing is wired without a confirmed target, and someone is always wired — there is no skip. The account signed into the Teams CLI is often NOT the person setting up NanoClaw, so a no leads to a clarifying choice: wire the logged-in Teams user after all, or a different Teams user by Microsoft Entra object ID. Identities are shown by sign-in name, never a raw ID:

Detected the account that created the bot: {{owner_upn}}. Wiring the assistant to it means its first message arrives in that account's Teams DMs.

Wire the assistant to this account?

You're currently logged in to Teams as {{owner_upn}}.
- To wire the assistant to this logged-in Teams user, choose "logged-in-account".
- To wire a different Teams user, get their Microsoft Entra object ID — found at entra.microsoft.com > Users > (person) > Overview > Object ID, or Teams admin center > Manage users — and choose "other-account". Once wired, the assistant messages them first.

Which Teams user should the assistant be wired to?

Paste the Microsoft Entra object ID of the Teams user to wire (a GUID like 00000000-0000-0000-0000-000000000000).

Either choice re-enters the exact same path as a yes above — rebind the wiring target and flip the branch, so the link chain below needs no second copy per branch:

printf '{"aad":"%s","wire":"yes"}' "{{target_aad_id}}"

echo yes

Install the app in Teams

The app package is already uploaded — no manifest zip, no manual sideload. Tell the user:

Install the bot into Teams:
1. Open {{install_link}} — Teams opens with the app's install dialog. Click Add.
2. If you need the link again later, run: teams app get {{teams_app_id}} --install-link
3. If Teams refuses with a custom-app-upload error, a tenant admin must enable sideloading: Teams Admin Center > Teams apps > Setup policies > Global > "Upload custom apps" = On.
Once the app shows up in your Teams sidebar (or app list), continue.

Link the bot to your account

Nothing to do in Teams yet — these are background API calls, and the whole chain runs only for a confirmed target from Confirm the wiring target (the detected owner on a yes, or the provided Entra object ID). Same move as Slack's conversations.open and Discord's users/@me/channels: create the bot↔owner 1:1 conversation proactively with the bot's own credentials, so the assistant messages the human first — nobody has to DM the bot to bootstrap it. This only works now that the app is installed (the step above); if Microsoft hasn't finished propagating the install yet, the create below can fail once — re-running the skill is safe.

First a Bot Framework token from the app credentials:

curl -sf -X POST "https://login.microsoftonline.com/{{app_tenant_id}}/oauth2/v2.0/token" --data-urlencode "grant_type=client_credentials" --data-urlencode "client_id={{app_id}}" --data-urlencode "client_secret={{app_password}}" --data-urlencode "scope=https://api.botframework.com/.default" | jq -er '.access_token'

Create the 1:1 conversation (the AAD object id from the CLI session is a valid member id; smba.trafficmanager.net/teams is the global service URL — the same default the adapter itself uses):

curl -sf -X POST "https://smba.trafficmanager.net/teams/v3/conversations" -H "Authorization: Bearer {{bot_token}}" -H "Content-Type: application/json" -d '{"bot":{"id":"28:{{app_id}}"},"members":[{"id":"{{owner_aad_id}}","name":"","role":"user"}],"tenantId":"{{app_tenant_id}}","channelData":{"tenant":{"id":"{{app_tenant_id}}"}},"isGroup":false}' | jq -er '.id'

The adapter identifies inbound senders by their Bot Framework 29: id, not the AAD id — the owner must be wired under that handle or their replies would not be recognized. The conversation was created with exactly one member (the owner), so its member list is the owner by construction; the filter only guards against channels that list the bot itself (28: ids). (Don't select by .aadObjectId here — the field is not reliably present in this response and its GUID casing varies.)

curl -sf "https://smba.trafficmanager.net/teams/v3/conversations/{{conversation_id}}/members" -H "Authorization: Bearer {{bot_token}}" | jq -er '[.[] | select((.id // "") | startswith("28:") | not)][0] | {id, name: (.name // .givenName // "Teams user")}'

Compose the platform id exactly as the adapter encodes thread ids (teams:{b64url conversation}:{b64url service url}):

node -e 'const c=process.argv[1];const s="https://smba.trafficmanager.net/teams/";console.log("teams:"+Buffer.from(c).toString("base64url")+":"+Buffer.from(s).toString("base64url"))' "{{conversation_id}}"

Sign out of the Teams CLI

The Microsoft 365 session was only needed to create the bot and identify its owner — the running adapter authenticates with the app credentials in .env, never with your account. On a headless box that session is a plaintext token file, which is worth removing unless you plan more teams … commands (rotate secret, endpoint update, RSC — each just needs a fresh teams login, a ~30-second device code):

Sign out of the Teams CLI now? The bot doesn't need this login to run — signing out is recommended on shared or headless boxes, and `teams login` gets you back any time.

"$(npm prefix -g 2>/dev/null)/bin/teams" logout

Restart

Restart the service so it loads the Teams adapter and the credentials you just stored:

bash setup/lib/restart.sh

Finish wiring

On a fresh create, Link the bot to your account already resolved everything the wire needs — owner_handle (the owner's 29: id) and platform_id (the bot↔owner DM). The setup wizard wires automatically from those and the welcome message lands in the owner's Teams DMs. Applying this skill outside the wizard? Run the same wire yourself:

pnpm exec tsx scripts/init-first-agent.ts --channel teams --user-id "teams:<owner_handle>" --platform-id "<platform_id>" --display-name "<the human's name>" --agent-name "<assistant name>" --role owner

Fallback (re-runs, or the link step failed): with credentials already in .env the resolve steps are skipped, so there is nothing new to wire — the first run's wiring still stands. If the install was never wired at all, the DM-first path always works: DM the bot once ("hi" is fine) — the router auto-creates the messaging group row in data/v2.db from that first inbound — then run /init-first-agent (or /manage-channels) with your coding agent.

Next Steps

If you're in the middle of /setup, return to the setup flow now — it wires the owner automatically from the resolved values. Otherwise wire per Finish wiring.

Channel Info

• type: teams
• terminology: Teams has "teams" containing "channels." The bot can also receive DMs (personal scope) and group chat messages. Channels support threaded replies.
• platform-id-format: teams:{base64url-conversation-id}:{base64url-service-url} — auto-generated by the adapter from the first inbound activity, not human-readable. Use the auto-created messaging group for wiring.
• how-to-find-id: Send a message to the bot in the channel or a DM. NanoClaw auto-creates a messaging group and logs the platform ID. Use that messaging group for wiring.
• supports-threads: yes (channels only; DMs and group chats are flat)
• typical-use: Team collaboration with the bot in channels; personal assistant via DMs
• default-isolation: Separate agent group per team. DMs can share an agent group with your main channel for unified personal memory.

Alternatives

Multi-tenant bot

The Credentials flow above always creates a single-tenant bot (only your Microsoft 365 tenant can install it) — the right default for a self-hosted assistant, so the skill doesn't ask. For a bot any tenant can install, run the create by hand with multipleOrgs and store the matching env pairing — MultiTenant with no tenant ID (the same 401 pairing rule from the credentials step):

"$(npm prefix -g)/bin/teams" app create --name "YourBot" --endpoint "https://your-domain/webhook/teams" --sign-in-audience multipleOrgs --json

TEAMS_APP_ID=<CLIENT_ID from the output>
TEAMS_APP_PASSWORD=<CLIENT_SECRET from the output>
TEAMS_APP_TYPE=MultiTenant

Install via the installLink in the output, then continue from Restart. If this skill already created a single-tenant app, start over first — see Rotate or recreate credentials in Troubleshooting.

Manual Azure portal path

For tenants where the Teams Developer Portal is blocked. Unlike the CLI path, the Azure Bot resource in step 3 requires an active Azure subscription. This is the classic walk; every value it produces maps onto the same .env keys. Ask the human before creating anything: the app registration name, single vs multi tenant, a client secret description, and (this path only) a separate Azure Bot handle.

1. App registration: in https://portal.azure.com, search "App registrations" → "New registration". Name it (e.g. "NanoClaw"); Supported account types: Single tenant (most common for self-host) or Multi tenant. From the Overview page copy the Application (client) ID and — single tenant only — the Directory (tenant) ID.

2. Client secret: in the app registration, "Certificates & secrets" → "New client secret" (expires 180 days or longer). Copy the Value now — Azure shows it once (the Value column, not the Secret ID).

3. Azure Bot resource: search "Azure Bot" → Create. Bot handle: any unique name; Type of App: must match step 1; Creation type: "Use existing app registration" with the App ID from step 1. After creating, open the bot → Configuration and set Messaging endpoint to https://your-domain/webhook/teams, then Apply.

4. Enable the Teams channel: Azure Bot resource → Channels → Microsoft Teams → Accept terms → Apply.

5. Store the credentials in .env (the same 401 pairing rule applies — SingleTenant needs the tenant ID, MultiTenant must omit it):

   TEAMS_APP_ID=<Application (client) ID>
   TEAMS_APP_PASSWORD=<client secret Value>
   TEAMS_APP_TYPE=SingleTenant
   TEAMS_APP_TENANT_ID=<Directory (tenant) ID>
   

6. Build the app package (manifest + icons, written in-process to data/teams/teams-app-package.zip — no zip binary needed):

   pnpm exec tsx setup/channels/teams-manifest-build.ts --app-id YOUR_APP_ID --url https://your-domain
   

7. Sideload: Microsoft Teams → Apps → Manage your apps → Upload an app → "Upload a custom app" → select the zip → Add.

8. Continue from Restart.

Or create the bot resource with the Azure CLI instead of the portal:

az group create --name nanoclaw-rg --location eastus
az bot create --resource-group nanoclaw-rg --name nanoclaw-bot --app-type SingleTenant --appid YOUR_APP_ID --tenant-id YOUR_TENANT_ID --endpoint "https://your-domain/webhook/teams"
az bot msteams create --resource-group nanoclaw-rg --name nanoclaw-bot

Optional configuration

Receive all channel messages (without @-mention)

By default the bot only receives messages when @-mentioned. With a CLI-created bot, grant the resource-specific-consent (RSC) permissions directly — no manifest edit, no re-upload; the app version is bumped automatically:

teams app rsc add <teams-app-id> ChannelMessage.Read.Group --type Application
teams app rsc add <teams-app-id> ChatMessage.Read.Chat --type Application

Then update/reinstall the app in the team so the new permissions get consented. (<teams-app-id> is the Teams App ID shown in the install step — recover it any time with teams app list, or find the app at https://dev.teams.microsoft.com/apps.)

On the manual path, regenerate the package with RSC baked in and sideload it again (the manifest version is bumped so the upload supersedes the original):

pnpm exec tsx setup/channels/teams-manifest-build.ts --app-id YOUR_APP_ID --url https://your-domain --rsc

Troubleshooting

"Upload a custom app" is missing / sideloading blocked

teams status shows whether sideloading is enabled at both tenant and user level; the login output prints the same check.

• Tenant level off: Teams Admin Center → Teams apps → Setup policies → Global → Upload custom apps = On.
• "Enabled for the tenant, but your user policy blocks it": the per-user policy is the blocker — Teams Admin Center → Users → find the user → Policies → App setup policy → assign one with Upload custom apps = On. Policy changes can take a while to propagate.

Free personal Teams does not support sideloading at all — use a Microsoft 365 Business / EDU / developer tenant.

The login step's sideloading probe is advisory — policy edits can take hours to propagate and the probe has been seen flapping between runs on the same account. The authoritative test is whether the install link's Add actually works; only act on the probe if the install itself refuses.

teams: command not found

The CLI installed fine but npm's global bin directory isn't on your PATH — a common state with custom npm prefixes. Find it with npm prefix -g (the binary is at <prefix>/bin/teams), then either add that directory to PATH or symlink the binary somewhere already on it. The skill's own steps are immune — they invoke the absolute path.

Create fails immediately with AUTH_REQUIRED after a successful sign-in

The sign-in didn't persist: each teams command is a separate process, and when the CLI's credential store can't load it silently falls back to an in-memory cache that dies with the login process. Symptom check: teams status says logged out right after a login succeeded. The known cause: the CLI was installed as a pnpm workspace dependency — pnpm's supply-chain policy skips dependency build scripts, so keytar (the CLI's native credential store) never gets its binary and the whole store fails to load. Use the global npm install this skill performs — and pnpm uninstall @microsoft/teams.cli if a workspace copy lingers, so teams resolves to the global one. (The "libsecret not found → stored unencrypted" warning is NOT this failure — that fallback persists fine and is safe to ignore.)

After fixing, sign in again and confirm teams status shows logged in, then re-run this skill.

Bot never receives messages

1. The app is actually installed in Teams — if setup was interrupted before the install step, nothing got installed. Recover the install link: teams app list shows the Teams App ID, then teams app get <teams-app-id> --install-link.
2. The tunnel is up and the messaging endpoint matches it — the endpoint must be https://<your-domain>/webhook/teams, and your tunnel (e.g. cloudflared tunnel --url http://localhost:3000) must be forwarding to this machine's port 3000. Check with teams app doctor <teams-app-id> (CLI-created bots) or Azure Bot → Configuration (manual path).
3. The adapter started: grep -i teams logs/nanoclaw.log | tail.
4. The credentials are in .env (TEAMS_APP_ID, TEAMS_APP_PASSWORD, TEAMS_APP_TYPE).

Tunnel URL changed

Point the bot at the new endpoint: teams app update <teams-app-id> --endpoint "https://new-domain/webhook/teams" (manual path: Azure Bot → Configuration → Messaging endpoint).

Unauthorized / 401 from Azure Bot Service

Either the credential pairing is wrong, or the secret is dead:

• Pairing: TEAMS_APP_TYPE=SingleTenant requires TEAMS_APP_TENANT_ID; MultiTenant must have no tenant ID set. A mismatch authenticates against the wrong authority and every send/receive 401s.
• Secret: expired or mispasted. Rotate with teams app auth secret create <teams-app-id> (or Azure portal → Certificates & secrets), update TEAMS_APP_PASSWORD in .env, and restart.

Rotate or recreate credentials

The credentials flow skips creation while .env has TEAMS_APP_ID or TEAMS_APP_PASSWORD — deleting just one line does not make the skill regenerate it (that would pair a new app with stale keys). To rotate only the secret, use the 401 section above. To start over completely: delete all TEAMS_* lines from .env, optionally delete the old app at https://dev.teams.microsoft.com/apps (CLI path) or in Azure Portal → App registrations (manual path), then re-run this skill. Re-running teams app create with old credentials still in .env would otherwise create a second, orphaned app.

Replies land in the wrong place

A Teams bot's platform ID is derived from the first inbound activity, so wire the messaging group that the router auto-creates after you DM the bot — don't guess the platform ID. See Finish wiring above.
