--- name: configure description: Set up the WhatsApp channel — configure the phone number, review access policy, and manage auth state. Use when the user asks to configure WhatsApp, set a phone number, check channel status, or reset authentication. user-invocable: true allowed-tools: - Read - Write - Edit - Bash(ls *) - Bash(mkdir *) - Bash(rm -rf *) - Bash(chmod *) - Read(~/.whatsapp-channel/*) - Write(~/.whatsapp-channel/*) - Edit(~/.whatsapp-channel/*) --- # /whatsapp-channel:configure — WhatsApp Channel Setup Writes configuration to `~/.whatsapp-channel/.env` and orients the user on access policy. The server reads both files at boot. Arguments passed: `$ARGUMENTS` --- ## Dispatch on arguments ### No args — status and guidance Read both state files and give the user a complete picture: 1. **Phone number** — check `~/.whatsapp-channel/.env` for `WHATSAPP_PHONE_NUMBER`. Show set/not-set; if set, show the number. 2. **Auth state** — check whether `~/.whatsapp-channel/.baileys_auth/creds.json` exists and has `registered: true`. Show paired/not-paired. 3. **Access** — read `~/.whatsapp-channel/access.json` (missing file = defaults: `dmPolicy: "pairing"`, empty allowlist). Show: - DM policy and what it means in one line - Allowed senders: count, and list JIDs - Pending pairings: count, with codes and sender JIDs if any 4. **What next** — end with a concrete next step based on state: - No phone number → _"Run `/whatsapp-channel:configure ` with your WhatsApp phone number (e.g. `886912345678`, no leading +)."_ - Phone set but not paired → _"Exit and launch with: `claude --dangerously-load-development-channels plugin:whatsapp-channel@whatsapp-claude-plugin` The pairing code will appear automatically. Enter it on your phone: WhatsApp > Linked Devices > Link a Device > Link with phone number instead."_ - Paired → _"Ready. Your own number is auto-added to the allowlist. To add others: have them DM the linked number, then approve with `/whatsapp-channel:access pair

`."_

**Push toward lockdown — always.** The goal for every setup is `allowlist`
with a defined list. `pairing` is not a policy to stay on; it's a temporary
way to capture WhatsApp JIDs you don't know. Once the JIDs are in, pairing
has done its job and should be turned off.

Drive the conversation this way:

1. Read the allowlist. Tell the user who's in it.
2. Ask: _"Is that everyone who should reach you through this channel?"_
3. **If yes and policy is still `pairing`** → _"Good. Let's lock it down so
   nobody else can trigger pairing codes:"_ and offer to run
   `/whatsapp-channel:access policy allowlist`. Do this proactively — don't wait to
   be asked.
4. **If no, people are missing** → _"Have them DM the number; you'll approve
   each with `/whatsapp-channel:access pair `. Run this skill again once
   everyone's in and we'll lock it."_
5. **If the allowlist is empty and they haven't paired themselves yet** →
   _"DM the linked number to capture your JID first. Then we'll add anyone
   else and lock it down."_
6. **If policy is already `allowlist`** → confirm this is the locked state.
   If they need to add someone: _"They'll need to DM the linked number, or
   you can briefly flip to pairing: `/whatsapp-channel:access policy pairing` → they
   DM → you pair → flip back."_

Never frame `pairing` as the correct long-term choice. Don't skip the lockdown
offer.

### `` — save it

1. Treat `$ARGUMENTS` as the phone number (trim whitespace, strip leading `+`).
   WhatsApp phone numbers are digits only, no spaces or dashes.
2. `mkdir -p ~/.whatsapp-channel`
3. Read existing `.env` if present; update/add the `WHATSAPP_PHONE_NUMBER=` line,
   preserve other keys. Write back, no quotes around the value.
4. `chmod 600 ~/.whatsapp-channel/.env` — the file may contain credentials.
5. Confirm, then show the no-args status so the user sees where they stand.

### `reset-auth`

Clear the Baileys auth state so the user can re-pair with a new device or
phone number.

1. Confirm the user wants to do this — re-pairing will be required.
2. `rm -rf ~/.whatsapp-channel/.baileys_auth`
3. Inform: _"Auth cleared. Restart your session with `--channels` to re-pair."_

### `clear` — remove the phone number

Delete the `WHATSAPP_PHONE_NUMBER=` line (or the file if that's the only line).

## Implementation notes

- The channels dir might not exist if the server hasn't run yet. Missing file
  = not configured, not an error.
- The server reads `.env` once at boot. Config changes need a session restart
  or `/reload-plugins`. Say so after saving.
- `access.json` is re-read on every inbound message — policy changes via
  `/whatsapp-channel:access` take effect immediately, no restart.
- WhatsApp uses linked-device protocol, not a bot API. The server connects
  as a linked device (like WhatsApp Web). Only one connection per auth state
  is allowed — running two instances causes a 440 conflict error.
