# Add Slack Channel Adds Slack support via the Chat SDK bridge. Trunk ships no channels — this skill copies the Slack channel layer (adapter, shared lib, bot-inbound guard, provisioning core, container skills) in from the `channels` branch. The **Apply** steps carry `nc:` directive fences (an agent applies the prose, a parser the directives); all idempotent. This is the base Slack experience: one bot, DM and channel chat. The Slack **agents** feature — child bots provisioned from `create_agent`, shared rooms, canvases, DM onboarding — ships separately in `/slack-a2a-rooms` + `/slack-agent-flow`, in-tree under `.claude/skills/` (their canonical home; the channels branch keeps a compatibility copy for older checkouts). The setup wizard applies them automatically, and they can be applied on top of this install at any time. Existing classic installs that want the Slack agents experience should use `/migrate-slack-agents` rather than re-running this skill (classic keeps working; that migration is optional). ## Apply ### 1. Copy the channel payload Fetch the `channels` branch and copy the payload into place (overwrite — the branch is canonical): ```nc:copy from-branch:channels src/channels/slack.ts src/channels/slack-lib.ts src/channels/slack-lib.test.ts src/channels/slack-a2a-guard.ts src/channels/slack-a2a-guard.test.ts src/channels/slack-raw-text.ts src/channels/slack-raw-text.test.ts src/channels/slack-registration.test.ts src/channels/slack-instances-registration.test.ts ...
