Add Discord Channel

This skill adds Discord support to NanoClaw using the skills engine for deterministic code changes, then walks through interactive setup.

Phase 1: Pre-flight

Check if already applied

Read .nanoclaw/state.yaml. If discord is in applied_skills, skip to Phase 3 (Setup). The code changes are already in place.

Ask the user

1. Mode: Replace WhatsApp or add alongside it?

   • Replace → will set DISCORD_ONLY=true
   • Alongside → both channels active (default)

2. Do they already have a bot token? If yes, collect it now. If no, we'll create one in Phase 3.

Phase 2: Apply Code Changes

Run the skills engine to apply this skill's code package. The package files are in this directory alongside this SKILL.md.

Initialize skills system (if needed)

If .nanoclaw/ directory doesn't exist yet:

npx tsx scripts/apply-skill.ts --init

Or call initSkillsSystem() from skills-engine/migrate.ts.

Apply the skill

npx tsx scripts/apply-skill.ts .claude/skills/add-discord

This deterministically:

• Adds src/channels/discord.ts (DiscordChannel class implementing Channel interface)
• Adds src/channels/discord.test.ts (unit tests with discord.js mock)
• Three-way merges Discord support into src/index.ts (multi-channel support, findChannel routing)
• Three-way merges Discord config into src/config.ts (DISCORD_BOT_TOKEN, DISCORD_ONLY exports)
• Three-way merges updated routing tests into src/routing.test.ts
• Installs the discord.js npm dependency
• Updates .env.example with DISCORD_BOT_TOKEN and DISCORD_ONLY
• Records the application in .nanoclaw/state.yaml

If the apply reports merge conflicts, read the intent files:

• modify/src/index.ts.intent.md — what changed and invariants for index.ts
• modify/src/config.ts.intent.md — what changed for config.ts

Validate code changes

npm test
npm run build

All tests must pass (including the new Discord tests) and build must be clean before proceeding.

Phase 3: Setup

Create Discord Bot (if needed)

If the user doesn't have a bot token, tell them:

I need you to create a Discord bot:

1. Go to the Discord Developer Portal
2. Click New Application and give it a name (e.g., "Andy Assistant")
3. Go to the Bot tab on the left sidebar
4. Click Reset Token to generate a new bot token — copy it immediately (you can only see it once)
5. Under Privileged Gateway Intents, enable:
   • Message Content Intent (required to read message text)
   • Server Members Intent (optional, for member display names)
6. Go to OAuth2 > URL Generator:
   • Scopes: select bot
   • Bot Permissions: select Send Messages, Read Message History, View Channels
   • Copy the generated URL and open it in your browser to invite the bot to your server

Wait for the user to provide the token.

Configure environment

Add to .env:

DISCORD_BOT_TOKEN=<their-token>

If they chose to replace WhatsApp:

DISCORD_ONLY=true

Sync to container environment:

cp .env data/env/env

The container reads environment from data/env/env, not .env directly.

Build and restart

npm run build
launchctl kickstart -k gui/$(id -u)/com.nanoclaw

Phase 4: Registration

Get Channel ID

Tell the user:

To get the channel ID for registration:

1. In Discord, go to User Settings > Advanced > Enable Developer Mode
2. Right-click the text channel you want the bot to respond in
3. Click Copy Channel ID

The channel ID will be a long number like 1234567890123456.

Wait for the user to provide the channel ID (format: dc:1234567890123456).

Register the channel

Use the IPC register flow or register directly. The channel ID, name, and folder name are needed.

For a main channel (responds to all messages, uses the main folder):

registerGroup("dc:<channel-id>", {
  name: "<server-name> #<channel-name>",
  folder: "main",
  trigger: `@${ASSISTANT_NAME}`,
  added_at: new Date().toISOString(),
  requiresTrigger: false,
});

For additional channels (trigger-only):

registerGroup("dc:<channel-id>", {
  name: "<server-name> #<channel-name>",
  folder: "<folder-name>",
  trigger: `@${ASSISTANT_NAME}`,
  added_at: new Date().toISOString(),
  requiresTrigger: true,
});

Phase 5: Verify

Test the connection

Tell the user:

Send a message in your registered Discord channel:

• For main channel: Any message works
• For non-main: @mention the bot in Discord

The bot should respond within a few seconds.

Check logs if needed

tail -f logs/nanoclaw.log

Troubleshooting

Bot not responding

1. Check DISCORD_BOT_TOKEN is set in .env AND synced to data/env/env
2. Check channel is registered: sqlite3 store/messages.db "SELECT * FROM registered_groups WHERE jid LIKE 'dc:%'"
3. For non-main channels: message must include trigger pattern (@mention the bot)
4. Service is running: launchctl list | grep nanoclaw
5. Verify the bot has been invited to the server (check OAuth2 URL was used)

Bot only responds to @mentions

This is the default behavior for non-main channels (requiresTrigger: true). To change:

• Update the registered group's requiresTrigger to false
• Or register the channel as the main channel

Message Content Intent not enabled

If the bot connects but can't read messages, ensure:

1. Go to Discord Developer Portal
2. Select your application > Bot tab
3. Under Privileged Gateway Intents, enable Message Content Intent
4. Restart NanoClaw

Getting Channel ID

If you can't copy the channel ID:

• Ensure Developer Mode is enabled: User Settings > Advanced > Developer Mode
• Right-click the channel name in the server sidebar > Copy Channel ID

After Setup

The Discord bot supports:

• Text messages in registered channels
• Attachment descriptions (images, videos, files shown as placeholders)
• Reply context (shows who the user is replying to)
• @mention translation (Discord <@botId> → NanoClaw trigger format)
• Message splitting for responses over 2000 characters
• Typing indicators while the agent processes
