Add Gchat

Add Google Chat Channel

Adds Google Chat support via the Chat SDK bridge.

Install

NanoClaw doesn't ship channels in trunk. This skill copies the Google Chat adapter in from the channels branch.

Pre-flight (idempotent)

Skip to Credentials if all of these are already in place:

• src/channels/gchat.ts exists
• src/channels/gchat-registration.test.ts exists
• src/channels/index.ts contains import './gchat.js';
• @chat-adapter/gchat is listed in package.json dependencies

Otherwise continue. Every step below is safe to re-run.

1. Fetch the channels branch

git fetch origin channels

2. Copy the adapter and its registration test

git show origin/channels:src/channels/gchat.ts                 > src/channels/gchat.ts
git show origin/channels:src/channels/gchat-registration.test.ts > src/channels/gchat-registration.test.ts

3. Append the self-registration import

Append to src/channels/index.ts (skip if the line is already present):

import './gchat.js';

4. Install the adapter package (pinned)

pnpm install @chat-adapter/gchat@4.29.0

5. Build and validate

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

Both must be clean before proceeding. gchat-registration.test.ts is the one integration test: it imports the real channel barrel and asserts the registry contains gchat. It goes red if the import './gchat.js'; line is deleted or drifts, if the barrel fails to evaluate, or if @chat-adapter/gchat isn't installed (the import throws) — so it also implicitly verifies the dependency from step 4. The adapter also calls core's createChatSdkBridge(...); that typed core-API consumption is guarded by pnpm run build.

End-to-end message delivery against a real Google Chat space is verified manually once the service is running — see Next Steps and the webhook setup above.

Credentials

> 1. Go to Google Cloud Console > 2. Create or select a project > 3. Enable the Google Chat API > 4. Go to Google Chat API > Configuration: > - App name and description > - Connection settings: select HTTP endpoint URL and set to https://your-domain/webhook/gchat > 5. Create a Service Account: > - Go to IAM & Admin > Service Accounts > Create Service Account > - Grant the Chat Bot role > - Create a JSON key and download it

Configure environment

Add the service account JSON as a single-line string to .env:

GCHAT_CREDENTIALS={"type":"service_account","project_id":"...","private_key":"...","client_email":"..."}

Sync to container: mkdir -p data/env && cp .env data/env/env

Next Steps

If you're in the middle of /setup, return to the setup flow now.

Otherwise, run /manage-channels to wire this channel to an agent group.

Channel Info

• type: gchat
• terminology: Google Chat has "spaces." A space can be a group conversation or a direct message with the bot.
• how-to-find-id: Open the space in Google Chat, look at the URL — the space ID is the segment after /space/ (e.g. spaces/AAAA...). Or use the Google Chat API to list spaces.
• supports-threads: yes
• typical-use: Interactive chat — team spaces or direct messages
• default-isolation: Same agent group for spaces where you're the primary user. Separate agent group for spaces with different teams or sensitive contexts.
