name	setup-channel
description	Set up project-local messaging channels (Telegram, iMessage, Things Cloud) so Claude can send/receive messages and read tasks for this project. Use when the user asks to "set up Telegram", "connect iMessage", or "enable Things Cloud sync" for this repo.

Set up messaging channels

Configure per-project messaging channels so Claude Code can send/receive messages and read tasks from this repo.

---

Channel Registry

Channel	Platform	Has dedicated skill?	Config location
Telegram	All	Yes: /telegram:configure, /telegram:access	.claude/channels/telegram/.env + access.json
iMessage	macOS only	Yes: /imessage:configure, /imessage:access	.claude/channels/imessage/access.json
Things Cloud	All	No (inline below)	THINGS_USERNAME/THINGS_PASSWORD via bws or env

To add a new channel: add a row to this table and a corresponding section below. The dispatch logic in Step 3 will handle it.

Instructions

1. Detect platform

Run uname -s to detect the platform (Linux or Darwin/macOS).

• Linux: Only Telegram and Things Cloud are available. iMessage requires macOS — if the user requests it on Linux, refuse with: "iMessage requires macOS — it reads from the local chat.db SQLite database which only exists on macOS."
• macOS: All channels are available.

2. Parse arguments and select channels

• If the user passed an argument (e.g., /setup-channel telegram or /setup-channel things), use that channel directly.
• If no argument, list available channels based on platform and ask which to configure (can be multiple).

3. Dispatch to channel setup

For each requested channel, look it up in the registry above and follow the section below:

---

Telegram

Telegram has a dedicated skill. Delegate:

1. Tell the user: "Telegram setup is handled by the /telegram:configure skill. Running it now…"
2. Invoke /telegram:configure — it handles token collection, directory creation, .env writing, and access.json scaffolding.
3. After configure completes, tell the user: "To pair your Telegram account, run /telegram:access."
4. Note the gotcha: The built-in /telegram:access skill edits the GLOBAL ~/.claude/channels/telegram/access.json, not the project-local one. Either pair before TELEGRAM_STATE_DIR is set, or edit the project-local access.json directly after pairing.
5. Ensure .claude/channels/ is in .gitignore (Step 4).

---

iMessage (macOS only)

iMessage has a dedicated skill. Delegate:

1. Tell the user: "iMessage setup is handled by the /imessage:configure skill. Running it now…"
2. Invoke /imessage:configure — it handles handle collection, directory creation, and access.json scaffolding.
3. After configure completes, tell the user: "To manage iMessage access, run /imessage:access."
4. Remind the user: Full Disk Access for Terminal/iTerm2 is required in System Settings > Privacy & Security > Full Disk Access (needed to read chat.db).
5. Ensure .claude/channels/ is in .gitignore (Step 4).

---

Things Cloud

Things Cloud has no dedicated skill — handle inline.

This is used by swordsmith-style bots that read tasks from Things 3 via the things-mcp plugin.

1. Ask how the user wants to store credentials:

   • bws (recommended) — credentials stored in BitWarden Secrets Manager, retrieved at session start. Ask for the secret name (e.g., THINGS_CLOUD_CREDS).
   • env vars (simpler) — THINGS_USERNAME and THINGS_PASSWORD set directly in .envrc.

2. For bws flow:

   • Tell the user to store their Things Cloud email + password as a JSON secret in bws: {"username": "...", "password": "..."}.
   • Add to .envrc (create or append):

     # Things Cloud credentials (via bws)
     eval "$(bws secret get <SECRET_NAME> | jq -r '"export THINGS_USERNAME=\(.value | fromjson | .username)\nexport THINGS_PASSWORD=\(.value | fromjson | .password)"')"
     

3. For env vars flow:

   • Ask for THINGS_USERNAME (Things Cloud email) and THINGS_PASSWORD.
   • Add to .envrc (create or append):

     export THINGS_USERNAME="<email>"
     export THINGS_PASSWORD="<password>"
     

   • Warn: Never commit .envrc containing plaintext credentials — ensure it's in .gitignore.

4. Create the things-mcp config directory:

   mkdir -p .claude/channels/things
   

5. Write .claude/channels/things/config.json:

   {
     "source": "cloud",
     "syncOnStart": 
   
   

---

4. Add .claude/channels/ to .gitignore (idempotent)

After configuring any channel, check .gitignore and add the entry if missing:

grep -qxF '.claude/channels/' .gitignore 2>/dev/null || echo '.claude/channels/' >> .gitignore

This step is idempotent — safe to run for every channel.

---

5. Show final status

After all requested channels are configured, show a summary:

Channel setup complete for <repo-name>

Configured channels:
  ✓ Telegram: .claude/channels/telegram/ (bot token set, pairing mode)
  ✓ iMessage: .claude/channels/imessage/ (allowlist: [e-mail])
  ✓ Things Cloud: .claude/channels/things/ (credentials via bws/env)

Skipped (already configured):
  — (none)

Next steps:
  - Telegram: DM the bot, then run /telegram:access to pair
  - iMessage: Ensure Full Disk Access is granted in System Settings
  - Things Cloud: Run `direnv allow` if using .envrc credentials
  - Start a session with `claude` from this directory — channels auto-activate

Adapt to show only the channels actually configured. If a channel was already configured (files exist), note it as skipped/unchanged.

Important Notes

• One Telegram bot per project. Sharing a bot token across projects causes competing pollers — only one session receives each message.
• Never commit .claude/channels/ — it contains bot tokens and credentials. Always gitignore it.
• The claude() wrapper handles activation. No manual env vars or --channels flags needed — the wrapper auto-detects channel directories at launch.
• Secrets-based Telegram flow: For storing the token in dotfiles-secrets instead of a plain .env, run setup-envrc --telegram-secret <SECRET_NAME> instead of letting /telegram:configure write the .env.
• Adding a new channel type: Add a row to the Channel Registry table and a new #### section in Step 3. No other changes needed.
