# Add Slack Channel Adds Slack support via the Chat SDK bridge. NanoClaw doesn't ship channels in trunk — this skill copies the Slack 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, registration test, and formatting skill Fetch the `channels` branch and copy the Slack adapter, its registration test, and the formatting container skill into place (overwrite — the branch is canonical): ```nc:copy from-branch:channels src/channels/slack.ts src/channels/slack-registration.test.ts container/skills/slack-formatting/SKILL.md ``` The `slack-formatting` container skill is part of the channel payload: it reaches agents via `~/.claude/skills` (synced at spawn) and teaches Slack's mrkdwn syntax. Trunk does not ship it — without this copy step agents send Slack messages with generic markdown that renders literally. ### 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 './slack.js'; ``` ### 3. Install the adapter package Pinned to an exact version — the supply-chain policy rej...
