Setup (check before using)

ruby ~/.claude/skills/discord/scripts/check_setup.rb

If the output is OK, proceed to the Flow section.

If the output is SETUP_NEEDED, guide the user step by step. Present ONE step at a time, wait for the user to confirm before moving to the next.

Step 1 — Ask the user to create a Discord bot and get the token:

You need a Discord Bot token. Go to the Discord Developer Portal: https://discord.com/developers/applications

Click New Application, give it a name

Go to Bot in the left menu

Click Reset Token and copy the token

Under Privileged Gateway Intents, enable Server Members Intent and Message Content Intent

Go to OAuth2 > URL Generator, select scope bot, then select permissions: Read Messages/View Channels, Send Messages, Manage Messages, Read Message History, Add Reactions

Copy the generated URL and open it to invite the bot to your server

Paste the bot token here.

Step 2 — When the user pastes the token, save it:

ruby ~/.claude/skills/discord/scripts/save_token.rb 'PASTED_TOKEN'

If the script outputs an error, the token is invalid. Ask the user to double-check and try again.

If setup is not complete, DO NOT proceed to the Flow. Complete all steps first.

Flow

The argument $ARGUMENTS may contain a server name or channel reference.

Step 1: List servers

ruby ~/.claude/skills/discord/scripts/guilds.rb

Present the servers. If there is only one, use it automatically. Otherwise ask which server to work with.

Step 2: List channels

ruby ~/.claude/skills/discord/scripts/channels.rb GUILD_ID
ruby ~/.claude/skills/discord/scripts/channels.rb GUILD_ID --type 0

Show text channels (type 0) by default. Ask which channel to work with.

Step 3: Actions

Read messages:

ruby ~/.claude/skills/discord/scripts/messages.rb CHANNEL_ID
ruby ~/.claude/skills/discord/scripts/messages.rb CHANNEL_ID --limit 50

Send a message (requires user confirmation):

Show the message content first, then ask to confirm before sending.

ruby ~/.claude/skills/discord/scripts/send_message.rb CHANNEL_ID "Hello from HiTank!"

Edit a message (requires user confirmation):

ruby ~/.claude/skills/discord/scripts/edit_message.rb CHANNEL_ID MESSAGE_ID "Updated content"

Delete a message (requires user confirmation):

Show the message first, then ask: "Do you want to delete this message?" Only execute after a "yes".

ruby ~/.claude/skills/discord/scripts/delete_message.rb CHANNEL_ID MESSAGE_ID

React to a message (requires user confirmation):

ruby ~/.claude/skills/discord/scripts/react.rb CHANNEL_ID MESSAGE_ID "✅"

Pin a message (requires user confirmation):

ruby ~/.claude/skills/discord/scripts/pin.rb CHANNEL_ID MESSAGE_ID

Create a thread (requires user confirmation):

ruby ~/.claude/skills/discord/scripts/thread_create.rb CHANNEL_ID MESSAGE_ID "Thread Name"

List members:

ruby ~/.claude/skills/discord/scripts/members.rb GUILD_ID
ruby ~/.claude/skills/discord/scripts/members.rb GUILD_ID --limit 100

List roles:

ruby ~/.claude/skills/discord/scripts/roles.rb GUILD_ID

Notes

Pure Ruby, zero gems — stdlib only (json, net/http, uri, fileutils)
Auth via Bot token (Authorization: Bot TOKEN)
Token file: ~/.config/discord/token (outside the repo, never commit)
Sending, editing, deleting messages, reacting, pinning, and creating threads require explicit user confirmation
Mention users as <@USER_ID> in message content
Avoid Markdown tables in outbound Discord messages
Rate limit: Discord uses per-route rate limits — check X-RateLimit-* headers
