Configure Discord

Configure Discord Notifications

Set up Discord notifications so OMX can ping you when sessions end, need input, or complete background tasks.

How This Skill Works

This is an interactive, natural-language configuration skill. Walk the user through setup by asking questions with AskUserQuestion. Write the result to ~/.codex/.omx-config.json.

Step 1: Detect Existing Configuration

CONFIG_FILE="$HOME/.codex/.omx-config.json"

if [ -f "$CONFIG_FILE" ]; then
  # Check for existing discord config
  HAS_DISCORD=$(jq -r '.notifications.discord.enabled // false' "$CONFIG_FILE" 2>/dev/null)
  HAS_DISCORD_BOT=$(jq -r '.notifications["discord-bot"].enabled // false' "$CONFIG_FILE" 2>/dev/null)
  WEBHOOK_URL=$(jq -r '.notifications.discord.webhookUrl // empty' "$CONFIG_FILE" 2>/dev/null)
  MENTION=$(jq -r '.notifications.discord.mention // empty' "$CONFIG_FILE" 2>/dev/null)

  if [ "$HAS_DISCORD" = "true" ] || [ "$HAS_DISCORD_BOT" = "true" ]; then
    echo "EXISTING_CONFIG=true"
    echo "WEBHOOK_CONFIGURED=$HAS_DISCORD"
    echo "BOT_CONFIGURED=$HAS_DISCORD_BOT"
    [ -n "$WEBHOOK_URL" ] && echo "WEBHOOK_URL=$WEBHOOK_URL"
    [ -n "$MENTION" ] && echo "MENTION=$MENTION"
  else
    echo "EXISTING_CONFIG=false"
  fi
else
  echo "NO_CONFIG_FILE"
fi

If existing config is found, show the user what's currently configured and ask if they want to update or reconfigure.

Step 2: Choose Discord Method

Use AskUserQuestion:

Question: "How would you like to send Discord notifications?"

Options:

1. Webhook (Recommended) - Create a webhook in your Discord channel. Simple, no bot needed. Just paste the URL.
2. Bot API - Use a Discord bot token + channel ID. More flexible, requires a bot application.

Step 3A: Webhook Setup

If user chose Webhook:

Use AskUserQuestion:

Question: "Paste your Discord webhook URL. To create one: Server Settings > Integrations > Webhooks > New Webhook > Copy URL"

The user will type their webhook URL in the "Other" field.

Validate the URL:

• Must start with https://discord.com/api/webhooks/ or https://discordapp.com/api/webhooks/
• If invalid, explain the format and ask again

Step 3B: Bot API Setup

If user chose Bot API:

Ask two questions:

1. "Paste your Discord bot token" - From discord.com/developers > Your App > Bot > Token
2. "Paste the channel ID" - Right-click channel > Copy Channel ID (requires Developer Mode)

Step 4: Configure Mention (User Ping)

Use AskUserQuestion:

Question: "Would you like notifications to mention (ping) someone?"

Options:

1. Yes, mention a user - Tag a specific user by their Discord user ID
2. Yes, mention a role - Tag a role by its role ID
3. No mentions - Just post the message without pinging anyone

If user wants to mention a user:

Ask: "What is the Discord user ID to mention? (Right-click user > Copy User ID, requires Developer Mode)"

The mention format is: <@USER_ID> (e.g., <@1465264645320474637>)

If user wants to mention a role:

Ask: "What is the Discord role ID to mention? (Server Settings > Roles > right-click role > Copy Role ID)"

The mention format is: <@&ROLE_ID> (e.g., <@&123456789>)

Step 5: Configure Events

Use AskUserQuestion with multiSelect:

Question: "Which events should trigger Discord notifications?"

Options (multiSelect: true):

1. Session end (Recommended) - When a Codex session finishes
2. Input needed - When Codex is waiting for your response (great for long-running tasks)
3. Session start - When a new session begins
4. Session continuing - When a persistent mode keeps the session alive

Default selection: session-end + ask-user-question.

Step 6: Optional Username Override

Use AskUserQuestion:

Question: "Custom bot display name? (Shows as the webhook sender name in Discord)"

Options:

1. OMX (default) - Display as "OMX"
2. Codex CLI - Display as "Codex CLI"
3. Custom - Enter a custom name

Step 7: Write Configuration

Read the existing config, merge the new Discord settings, and write back:

CONFIG_FILE="$HOME/.codex/.omx-config.json"
mkdir -p "$(dirname "$CONFIG_FILE")"

if [ -f "$CONFIG_FILE" ]; then
  EXISTING=$(cat "$CONFIG_FILE")
else
  EXISTING='{}'
fi

For Webhook method:

Build the notifications object with the collected values and merge into .omx-config.json using jq:

# WEBHOOK_URL, MENTION, USERNAME are collected from user
# EVENTS is the list of enabled events

echo "$EXISTING" | jq \
  --arg url "$WEBHOOK_URL" \
  --arg mention "$MENTION" \
  --arg username "$USERNAME" \
  '.notifications = (.notifications // {enabled: true}) |
   .notifications.enabled = true |
   .notifications.discord = {
     enabled: true,
     webhookUrl: $url,
     mention: (if $mention == "" then null else $mention end),
     username: (if $username == "" then null else $username end)
   }' > "$CONFIG_FILE"

For Bot API method:

echo "$EXISTING" | jq \
  --arg token "$BOT_TOKEN" \
  --arg channel "$CHANNEL_ID" \
  --arg mention "$MENTION" \
  '.notifications = (.notifications // {enabled: true}) |
   .notifications.enabled = true |
   .notifications["discord-bot"] = {
     enabled: true,
     botToken: $token,
     channelId: $channel,
     mention: (if $mention == "" then null else $mention end)
   }' > "$CONFIG_FILE"

Add event-specific config if user didn't select all events:

For each event NOT selected, disable it:

# Example: disable session-start if not selected
echo "$(cat "$CONFIG_FILE")" | jq \
  '.notifications.events = (.notifications.events // {}) |
   .notifications.events["session-start"] = {enabled: false}' > "$CONFIG_FILE"

Step 8: Test the Configuration

After writing config, offer to send a test notification:

Use AskUserQuestion:

Question: "Send a test notification to verify the setup?"

Options:

1. Yes, test now (Recommended) - Send a test message to your Discord channel
2. No, I'll test later - Skip testing

If testing:

# For webhook:
curl -s -o /dev/null -w "%{http_code}" \
  -H "Content-Type: application/json" \
  -d "{\"content\": \"${MENTION:+$MENTION\\n}OMX test notification - Discord is configured!\"}" \
  "$WEBHOOK_URL"

Report success or failure. If it fails, help the user debug (check URL, permissions, etc.).

Step 9: Confirm

Display the final configuration summary:

Discord Notifications Configured!

  Method:   Webhook / Bot API
  Mention:  <@1465264645320474637> (or "none")
  Events:   session-end, ask-user-question
  Username: OMX

Config saved to: ~/.codex/.omx-config.json

You can also set these via environment variables:
  OMX_DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/...
  OMX_DISCORD_MENTION=<@1465264645320474637>

To reconfigure: /configure-discord
To configure Telegram: /configure-telegram

Environment Variable Alternative

Users can skip this wizard entirely by setting env vars in their shell profile:

Webhook method:

export OMX_DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."
export OMX_DISCORD_MENTION="<@1465264645320474637>"  # optional

Bot API method:

export OMX_DISCORD_NOTIFIER_BOT_TOKEN="your-bot-token"
export OMX_DISCORD_NOTIFIER_CHANNEL="your-channel-id"
export OMX_DISCORD_MENTION="<@1465264645320474637>"  # optional

Env vars are auto-detected by the notification system without needing .omx-config.json.
