Add GitHub Channel

Adds GitHub support via the Chat SDK bridge. The agent participates in PR and issue comment threads. NanoClaw doesn't ship channels in trunk, this skill copies the GitHub 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.

Prerequisites

You need a dedicated GitHub bot account (not your personal account). The adapter uses this account to post replies and filters out its own messages to avoid loops. Create a free GitHub account for your bot (e.g. my-org-bot), then invite it as a collaborator with write access to the repos you want monitored.

Apply

1. Copy the adapter

Fetch the channels branch and copy the GitHub adapter into src/channels/ (overwrite, the branch is canonical):

src/channels/github.ts
src/channels/github-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 './github.js';

3. Install the adapter package

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

@chat-adapter/github@4.41.1

4. Build and validate

The build guards the typed createChatSdkBridge(...) core call and proves the dependency is installed (the adapter import throws if @chat-adapter/github isn't present):

pnpm run build

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