Add Linear Channel

Adds Linear support via the Chat SDK bridge. The agent participates in issue comment threads. Every comment on a Linear issue triggers the agent, no @-mention needed. NanoClaw doesn't ship channels in trunk, this skill copies the Linear 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

Recommended: Create a Linear OAuth application so the agent posts as an app identity, not as you. This prevents the adapter from filtering your own comments as self-messages.

1. Go to Linear Settings > API > OAuth Applications
2. Create an app (e.g. "NanoClaw Bot")
   • Developer URL: your repo URL (e.g. https://github.com/your-org/nanoclaw)
   • Callback URL: http://localhost
3. After creating, click the app and enable Client credentials under grant types
4. Copy the Client ID and Client Secret

Alternative: Use a Personal API Key (LINEAR_API_KEY) for simpler setup. The agent will post as you, and your own comments will be filtered (other team members' comments still work).

Apply

Linear OAuth apps post and read comments under an app identity that can't be @-mentioned; the adapter's declared channel defaults therefore respond to plain comments rather than mention-only, and the wiring below sets that same pattern mode explicitly.

1. Copy the adapter and its registration test

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

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

2. Register the adapter
