description: Guided channel activation for local/tmux users — adds a channel entry when none is configured, installs the plugin, configures the bot token in the project-local state dir, and walks through pairing. Run after hatch, or any time to add or re-enable a channel.

Channel Setup

Activate a channel, adding the `config.json` entry first when there isn't one. Local/tmux pairing is this skill's own flow; a Docker hermit is routed by the check below.

Plan

1. Read config and detect channels

**Runtime routing (first):** evaluate in this order.

1. **Inside the container.** Run `[ -f /.dockerenv ] || [ -f /run/.containerenv ] && echo container || echo host`. If `container`: read `.claude-code-hermit/config.json`. For each enabled channel object, resolve `state_dir` as step 4 does (config `state_dir`, default `.claude.local/channels/<channel>`; if relative, make it absolute against the project root) and print that absolute path literally. Print and stop: > DM the bot for a code, then run `/claude-code-hermit:channel-setup` from a normal host session at the project root. If no enabled channel, print only the host-run sentence and stop. No `AskUserQuestion` on this path.

2. **No compose file.** If `docker-compose.hermit.yml` is absent at the project root, continue with the local/tmux flow below.

3. **Live tmux hermit.** Run `bun ${CLAUDE_PLUGIN_ROOT}/scripts/docker-preflight.ts "$(pwd)"`. If its `liveOwner` is non-null, a host tmux hermit owns this project despite the compose file: continue with the local/tmux flow below.

4. **Compose present.** Run `docker compose -f docker-compose.hermit.yml ps --status running --format '{{.Service}}'`. Non-zero exit → print its output, stop. If `hermit` is absent from the output: after channel selection, run steps 2 and 4, skip 3, then stop with `.claude-code-hermit/bin/hermit-docker up` and "re-run this skill to pair". If `hermit` is present: docker-running.

5. **docker-running.** After channel selection, skip step 3 (the container installs channel plugins at boot). Run step 4; a `SKIP … HTTP 401` or `403` from its `channel-bot-id.ts` line is reported as "token rejected by <platform>, fix it before restarting". If this run created the config entry or wrote the token → stop: "The bot is offline until the container restarts and loads it: `.claude-code-hermit/bin/hermit-docker restart`, then DM the bot for a code and re-run this skill. Still no code after a restart: `hermit-docker logs --tail=60` shows the plugin's own error (wrong token, missing Message Content intent, install failure), and `/claude-code-hermit:hermit-doctor` checks the token." Otherwise run §5, §6, §6a, §6b, and §6c against the host-visible channel `<state_dir>`, passing the absolute project `.claude-code-hermit` directory as `<hermit_state_dir>` to `channel-access.ts`. No restart prompt is needed for an already-running bot. Continue with §6d, §6e, then §7 for each paired channel. Add to the pairing question: "No code from the bot? It has not loaded the token: `hermit-docker restart`, then re-run this skill."

Read `.claude-code-hermit/config.json`. Collect all entries under `channels` that are valid objects, tracking which are disabled (`enabled: false`).

**Adding an entry.** Where a branch below says *create the entry*, run (`<name>` is the lowercase channel key — `discord`, `telegram` — never the capitalized option label):

echo '{"channels":{"<name>":{"enabled":true}}}' | bun ${CLAUDE_PLUGIN_ROOT}/scripts/hatch-config.ts "$(pwd)" --reinit >/dev/null

The script fills `enabled`, `dm_channel_id: null`, `default_chat_id: null`, and `state_dir` (`.claude.local/channels/<name>`), validates the whole config, preserves every other key, and merges onto an existing entry rather than replacing it. Discard stdout — it prints the full config. A non-zero exit means nothing was written: report the `hatch-config:` line it printed on stderr and stop — never fall through into steps 2–6 against a channel that isn't in `config.json`.

• If no channels configured: offer to add one — `AskUserQuestion` (header: "Channel") with options **Discord**, **Telegram**, **Cancel**. On **Cancel**, stop without writing. Otherwise create the entry and continue with that channel selected. Do not offer iMessage here: step 4 defines token vars for Discord and Telegram only.
• If entries exist but all are disabled: name them, then ask with `AskUserQuestion` (header: "Channel") — the disabled channel names plus **Cancel** — which to re-enable. On **Cancel**, stop without writing. Otherwise create the entry for the chosen name (this flips `enabled` and leaves `dm_channel_id`, `default_chat_id`, `state_dir`, and `allowed_users` intact) and continue with it selected.
• If exactly one enabled channel and nothing disabled: use it automatically.
• Otherwise (several enabled, or enabled and disabled side by side): ask with `AskUserQuestion` (header: "Channel") — every channel name as an option, disabled ones labelled `<name> — disabled`, plus **All** (enabled channels only) — which to set up. If a disabled name is chosen, create the entry for it first (re-enabling it), then continue with it selected.

Run steps 2–6 for each selected channel. On a Docker host (runtime routing 4–5), apply those overrides instead of the local/tmux default.

2. Check prerequisites

Run both checks in a single Bash call:

bun --version 2>/dev/null; uname -s

• **Bun missing** (command fails / no output): tell the operator —

> Bun is required for channel plugins but is not installed. > Install: https://bun.sh > Then re-run this skill.

Stop for this channel.

• **iMessage on non-macOS**: if `uname -s` is not `Darwin` and the channel is `imessage`, note it's macOS-only and skip this channel.

3. Install plugin

Run `bun ${CLAUDE_PLUGIN_ROOT}/scripts/resolve-siblings.ts "$(pwd)"` to get the project-or-local + enabled plugin list (JSON ar
