# Add Google Chat Channel Adds Google Chat support via the Chat SDK bridge. NanoClaw doesn't ship channels in trunk — this skill copies the Google Chat 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. ## Apply ### 1. Copy the adapter and its registration test Fetch the `channels` branch and copy the Google Chat adapter and its registration test into `src/channels/` (overwrite — the branch is canonical): ```nc:copy from-branch:channels src/channels/gchat.ts src/channels/gchat-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: ```nc:append to:src/channels/index.ts import './gchat.js'; ``` ### 3. Install the adapter package Pinned to an exact version — the supply-chain policy rejects ranges and `latest`: ```nc:dep @chat-adapter/gchat@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. ```nc:run effect:build pnpm run build ``` ```nc:run effect:test pnpm exec vitest run src/channels/gcha...
