Configure Notifications

Set up OMC notification integrations so you're alerted when sessions end, need input, or complete background tasks.

Routing

Detect which provider the user wants based on their request or argument:

• If the trigger or argument contains "telegram" → follow the Telegram section
• If the trigger or argument contains "discord" → follow the Discord section
• If the trigger or argument contains "slack" → follow the Slack section
• If no provider is specified, use AskUserQuestion:

Question: "Which notification service would you like to configure?"

Options:

1. Telegram - Bot token + chat ID. Works on mobile and desktop.
2. Discord - Webhook or bot token + channel ID.
3. Slack - Incoming webhook URL.

---

Telegram Setup

Set up Telegram notifications so OMC can message 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 ~/.claude/.omc-config.json.

Step 1: Detect Existing Configuration

CONFIG_FILE="$HOME/.claude/.omc-config.json"

if [ -f "$CONFIG_FILE" ]; then
  HAS_TELEGRAM=$(jq -r '.notifications.telegram.enabled // false' "$CONFIG_FILE" 2>/dev/null)
  CHAT_ID=$(jq -r '.notifications.telegram.chatId // empty' "$CONFIG_FILE" 2>/dev/null)
  PARSE_MODE=$(jq -r '.notifications.telegram.parseMode // "Markdown"' "$CONFIG_FILE" 2>/dev/null)

  if [ "$HAS_TELEGRAM" = "true" ]; then
    echo "EXISTING_CONFIG=true"
    echo "CHAT_ID=$CHAT_ID"
    echo "PARSE_MODE=$PARSE_MODE"
  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: Create a Telegram Bot

Guide the user through creating a bot if they don't have one:

To set up Telegram notifications, you need a Telegram bot token and your chat ID.

CREATE A BOT (if you don't have one):
1. Open Telegram and search for @BotFather
2. Send /newbot
3. Choose a name (e.g., "My OMC Notifier")
4. Choose a username (e.g., "my_omc_bot")
5. BotFather will give you a token like: 123456789:ABCdefGHIjklMNOpqrsTUVwxyz

GET YOUR CHAT ID:
1. Start a chat with your new bot (send /start)
2. Visit: https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates
3. Look for "chat":{"id":YOUR_CHAT_ID}
   - Personal chat IDs are positive numbers (e.g., 123456789)
   - Group chat IDs are negative numbers (e.g., -1001234567890)

Step 3: Collect Bot Token

Use AskUserQuestion:

Question: "Paste your Telegram bot token (from @BotFather)"

The user will type their token in the "Other" field.

Validate the token:

• Must match pattern: digits:alphanumeric (e.g., 123456789:ABCdefGHI...)
• If invalid, explain the format and ask again

Step 4: Collect Chat ID

Use AskUserQuestion:

Question: "Paste your Telegram chat ID (the number from getUpdates API)"

The user will type their chat ID in the "Other" field.

Validate the chat ID:

• Must be a number (positive for personal, negative for groups)
• If invalid, offer to help them find it:

# Help user find their chat ID
BOT_TOKEN="USER_PROVIDED_TOKEN"
echo "Fetching recent messages to find your chat ID..."
curl -s "https://api.telegram.org/bot${BOT_TOKEN}/getUpdates" | jq '.result[-1].message.chat.id // .result[-1].message.from.id // "No messages found - send /start to your bot first"'

Step 5: Choose Parse Mode

Use AskUserQuestion:

Question: "Which message format do you prefer?"

Options:

1. Markdown (Recommended) - Bold, italic, code blocks with Markdown syntax
2. HTML - Bold, italic, code with HTML tags

Step 6: Configure Events

Use AskUserQuestion with multiSelect:

Question: "Which events should trigger Telegram notifications?"

Options (multiSelect: true):

1. Session end (Recommended) - When a Claude session finishes
2. Input needed - When Claude 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 7: Write Configuration

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

CONFIG_FILE="$HOME/.claude/.omc-config.json"
mkdir -p "$(dirname "$CONFIG_FILE")"

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

# BOT_TOKEN, CHAT_ID, PARSE_MODE are collected from user
echo "$EXISTING" | jq \
  --arg token "$BOT_TOKEN" \
  --arg chatId "$CHAT_ID" \
  --arg parseMode "$PARSE_MODE" \
  '.notifications = (.notifications // {enabled: true}) |
   .notifications.enabled = true |
   .notifications.telegram = {
     enabled: true,
     botToken: $token,
     chatId: $chatId,
     parseMode: $parseMode
   }' > "$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 Telegram chat
2. No, I'll test later - Skip testing

If testing:

BOT_TOKEN="USER_PROVIDED_TOKEN"
CHAT_ID="USER_PROVIDED_CHAT_ID"
PARSE_MODE="Markdown"

RESPONSE=$(curl -s -w "\n%{http_code}" \
  "https://api.telegram.org/bot${BOT_TOKEN}/sendMessage" \
  -d "chat_id=${CHAT_ID}" \
  -d "parse_mode=${PARSE_MODE}" \
  -d "text=OMC test notification - Telegram is configured!")

HTTP_CODE=$(echo "$RESPONSE" | tail -1)
BODY=$(echo "$RESPONSE" | head -1)

if [ "$HTTP_CODE" = "200" ]; then
  echo "Test notification sent successfully!"
else
  echo "Failed (HTTP $HTTP_CODE):"
  echo "$BODY" | jq -r '.description // "Unknown error"' 2>/dev/null || echo "$BODY"
fi

Report success or failure. Common issues:

• 401 Unauthorized: Bot token is invalid
• 400 Bad Request: chat not found: Chat ID is wrong, or user hasn't sent /start to the bot
• Network error: Check connectivity to api.telegram.org

Step 9: Confirm

Display the final configuration summary:

Telegram Notifications Configured!

  Bot:        @your_bot_username
  Chat ID:    123456789
  Format:     Markdown
  Events:     session-end, ask-user-question

Config saved to: ~/.claude/.omc-config.json

You can also set these via environment variables:
  OMC_TELEGRAM_BOT_TOKEN=123456789:ABCdefGHI...
  OMC_TELEGRAM_CHAT_ID=123456789

To reconfigure: /oh-my-claudecode:configure-notifications telegram
To configure Discord: /oh-my-claudecode:configure-notifications discord
To configure Slack: /oh-my-claudecode:configure-notifications slack

Environment Variable Alternative

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

export OMC_TELEGRAM_BOT_TOKEN="123456789:ABCdefGHIjklMNOpqrsTUVwxyz"
export OMC_TELEGRAM_CHAT_ID="123456789"

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

---

Discord Setup

Set up Discord notifications so OMC 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 ~/.claude/.omc-config.json.

Step 1: Detect Existing Configuration

CONFIG_FILE="$HOME/.claude/.omc-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 Claude session finishes
2. Input needed - When Claude 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. OMC (default) - Display as "OMC"
2. Claude Code - Display as "Claude Code"
3. Custom - Enter a custom name

Step 7: Write Configuration

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

CONFIG_FILE="$HOME/.claude/.omc-config.json"
mkdir -p "$(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 .omc-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}OMC 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: OMC

Config saved to: ~/.claude/.omc-config.json

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

To reconfigure: /oh-my-claudecode:configure-notifications discord
To configure Telegram: /oh-my-claudecode:configure-notifications telegram
To configure Slack: /oh-my-claudecode:configure-notifications slack

Environment Variable Alternative

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

Webhook method:

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

Bot API method:

export OMC_DISCORD_NOTIFIER_BOT_TOKEN="your-bot-token"
export OMC_DISCORD_NOTIFIER_CHANNEL="your-channel-id"
export OMC_DISCORD_MENTION="<@1465264645320474637>"  # optional

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

Slack Setup

Set up Slack notifications so OMC can message 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 ~/.claude/.omc-config.json.

Step 1: Detect Existing Configuration

CONFIG_FILE="$HOME/.claude/.omc-config.json"

if [ -f "$CONFIG_FILE" ]; then
  HAS_SLACK=$(jq -r '.notifications.slack.enabled // false' "$CONFIG_FILE" 2>/dev/null)
  WEBHOOK_URL=$(jq -r '.notifications.slack.webhookUrl // empty' "$CONFIG_FILE" 2>/dev/null)
  MENTION=$(jq -r '.notifications.slack.mention // empty' "$CONFIG_FILE" 2>/dev/null)
  CHANNEL=$(jq -r '.notifications.slack.channel // empty' "$CONFIG_FILE" 2>/dev/null)

  if [ "$HAS_SLACK" = "true" ]; then
    echo "EXISTING_CONFIG=true"
    [ -n "$WEBHOOK_URL" ] && echo "WEBHOOK_URL=$WEBHOOK_URL"
    [ -n "$MENTION" ] && echo "MENTION=$MENTION"
    [ -n "$CHANNEL" ] && echo "CHANNEL=$CHANNEL"
  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: Create a Slack Incoming Webhook

Guide the user through creating a webhook if they don't have one:

To set up Slack notifications, you need a Slack incoming webhook URL.

CREATE A WEBHOOK:
1. Go to https://api.slack.com/apps
2. Click "Create New App" > "From scratch"
3. Name your app (e.g., "OMC Notifier") and select your workspace
4. Go to "Incoming Webhooks" in the left sidebar
5. Toggle "Activate Incoming Webhooks" to ON
6. Click "Add New Webhook to Workspace"
7. Select the channel where notifications should be posted
8. Copy the webhook URL (starts with https://hooks.slack.com/services/...)

Step 3: Collect Webhook URL

Use AskUserQuestion:

Question: "Paste your Slack incoming webhook URL (starts with https://hooks.slack.com/services/...)"

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

Validate the URL:

• Must start with https://hooks.slack.com/services/
• If invalid, explain the format and ask again

Step 4: Configure Mention (User/Group Ping)

Use AskUserQuestion:

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

Options:

1. Yes, mention a user - Tag a specific user by their Slack member ID
2. Yes, mention a channel - Use @channel to notify everyone in the channel
3. Yes, mention @here - Notify only active members in the channel
4. No mentions - Just post the message without pinging anyone

If user wants to mention a user:

Ask: "What is the Slack member ID to mention? (Click on a user's profile > More (⋯) > Copy member ID)"

The mention format is: <@MEMBER_ID> (e.g., <@U1234567890>)

If user wants @channel:

The mention format is: <!channel>

If user wants @here:

The mention format is: <!here>

Step 5: Configure Events

Use AskUserQuestion with multiSelect:

Question: "Which events should trigger Slack notifications?"

Options (multiSelect: true):

1. Session end (Recommended) - When a Claude session finishes
2. Input needed - When Claude 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 Channel Override

Use AskUserQuestion:

Question: "Override the default notification channel? (The webhook already has a default channel)"

Options:

1. Use webhook default (Recommended) - Post to the channel selected during webhook setup
2. Override channel - Specify a different channel (e.g., #alerts)

If override, ask for the channel name (e.g., #alerts).

Step 7: Optional Username Override

Use AskUserQuestion:

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

Options:

1. OMC (default) - Display as "OMC"
2. Claude Code - Display as "Claude Code"
3. Custom - Enter a custom name

Step 8: Write Configuration

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

CONFIG_FILE="$HOME/.claude/.omc-config.json"
mkdir -p "$(dirname "$CONFIG_FILE")"

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

# WEBHOOK_URL, MENTION, USERNAME, CHANNEL are collected from user
echo "$EXISTING" | jq \
  --arg url "$WEBHOOK_URL" \
  --arg mention "$MENTION" \
  --arg username "$USERNAME" \
  --arg channel "$CHANNEL" \
  '.notifications = (.notifications // {enabled: true}) |
   .notifications.enabled = true |
   .notifications.slack = {
     enabled: true,
     webhookUrl: $url,
     mention: (if $mention == "" then null else $mention end),
     username: (if $username == "" then null else $username end),
     channel: (if $channel == "" then null else $channel end)
   }' > "$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 9: 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 Slack channel
2. No, I'll test later - Skip testing

If testing:

# For webhook:
MENTION_PREFIX=""
if [ -n "$MENTION" ]; then
  MENTION_PREFIX="${MENTION}\n"
fi

curl -s -o /dev/null -w "%{http_code}" \
  -H "Content-Type: application/json" \
  -d "{\"text\": \"${MENTION_PREFIX}OMC test notification - Slack is configured!\"}" \
  "$WEBHOOK_URL"

Report success or failure. Common issues:

• 403 Forbidden: Webhook URL is invalid or revoked
• 404 Not Found: Webhook URL is incorrect
• channel_not_found: Channel override is invalid
• Network error: Check connectivity to hooks.slack.com

Step 10: Confirm

Display the final configuration summary:

Slack Notifications Configured!

  Webhook:  https://hooks.slack.com/services/T00/B00/xxx...
  Mention:  <@U1234567890> (or "none")
  Channel:  #alerts (or "webhook default")
  Events:   session-end, ask-user-question
  Username: OMC

Config saved to: ~/.claude/.omc-config.json

You can also set these via environment variables:
  OMC_SLACK_WEBHOOK_URL=https://hooks.slack.com/services/...
  OMC_SLACK_MENTION=<@U1234567890>

To reconfigure: /oh-my-claudecode:configure-notifications slack
To configure Discord: /oh-my-claudecode:configure-notifications discord
To configure Telegram: /oh-my-claudecode:configure-notifications telegram

Environment Variable Alternative

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

export OMC_SLACK_WEBHOOK_URL="https://hooks.slack.com/services/T00/B00/xxx"
export OMC_SLACK_MENTION="<@U1234567890>"  # optional

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

Slack Mention Formats

Type	Format	Example
User	<@MEMBER_ID>	<@U1234567890>
Channel	<!channel>	<!channel>
Here	<!here>	<!here>
Everyone	<!everyone>	<!everyone>
User Group	<!subteam^GROUP_ID>	<!subteam^S1234567890>

---

Platform Activation Flags

All notification platforms require activation via CLI flags per session:

• omc --telegram — Activates Telegram notifications (sets OMC_TELEGRAM=1)
• omc --discord — Activates Discord notifications (sets OMC_DISCORD=1)
• omc --slack — Activates Slack notifications (sets OMC_SLACK=1)
• omc --webhook — Activates webhook notifications (sets OMC_WEBHOOK=1)
• omc --openclaw — Activates OpenClaw gateway integration (sets OMC_OPENCLAW=1)

Without these flags, configured platforms remain dormant. This prevents unwanted notifications during development while keeping configuration persistent.

Examples:

• omc --telegram --discord — Telegram + Discord active
• omc --telegram --slack --webhook — Telegram + Slack + Webhook active
• omc --telegram --openclaw — Telegram + OpenClaw active
• omc — No notifications sent (all platforms require explicit activation)

---

Hook Event Templates

Customize notification messages per event and per platform using omc_config.hook.json.

Routing

If the trigger or argument contains "hook", "template", or "customize messages" → follow this section.

Step 1: Detect Existing Hook Config

Check if ~/.claude/omc_config.hook.json exists. If it does, show the current configuration. If not, explain what it does.

Hook event templates let you customize the notification messages sent to each platform.
You can set different messages for Discord vs Telegram vs Slack, and control which
events fire on which platform.

Config file: ~/.claude/omc_config.hook.json

Step 2: Choose Event to Configure

Use AskUserQuestion:

Question: "Which event would you like to configure templates for?"

Options:

1. session-end - When a Claude session finishes (most common)
2. ask-user-question - When Claude is waiting for input
3. session-idle - When Claude finishes and waits for input
4. session-start - When a new session begins

Step 3: Show Available Variables

Display the template variables available for the chosen event:

Available template variables:

RAW FIELDS:
  {{sessionId}}      - Session identifier
  {{timestamp}}      - ISO timestamp
  {{tmuxSession}}    - tmux session name
  {{projectPath}}    - Full project directory path
  {{projectName}}    - Project directory basename
  {{reason}}         - Stop/end reason
  {{activeMode}}     - Active OMC mode name
  {{question}}       - Question text (ask-user-question only)
  {{agentName}}      - Agent name (agent-call only)
  {{agentType}}      - Agent type (agent-call only)

COMPUTED (smart formatting):
  {{duration}}       - Human-readable duration (e.g., "5m 23s")
  {{time}}           - Locale time string
  {{modesDisplay}}   - Comma-separated modes or empty
  {{iterationDisplay}} - "3/10" format or empty
  {{agentDisplay}}   - "2/5 completed" or empty
  {{projectDisplay}} - Project name with fallbacks
  {{footer}}         - tmux + project info line
  {{tmuxTailBlock}}  - Recent output in code fence or empty
  {{reasonDisplay}}  - Reason with "unknown" fallback

CONDITIONALS:
  {{#if variableName}}content shown when truthy{{/if}}

Step 4: Collect Template

Use AskUserQuestion:

Question: "Enter the message template for this event (use {{variables}} for dynamic content)"

Options:

1. Use default template - Keep the built-in message format
2. Simple summary - Short one-line format
3. Custom - Enter your own template

If "Simple summary", use a pre-built compact template:

• session-end: {{projectDisplay}} session ended ({{duration}}) — {{reasonDisplay}}
• ask-user-question: Input needed on {{projectDisplay}}: {{question}}
• session-idle: {{projectDisplay}} is idle. {{#if reason}}Reason: {{reason}}{{/if}}
• session-start: Session started: {{projectDisplay}} at {{time}}

Step 5: Per-Platform Overrides

Use AskUserQuestion:

Question: "Do you want different messages for specific platforms?"

Options:

1. No, same for all (Recommended) - Use the same template everywhere
2. Yes, customize per platform - Set different templates for Discord, Telegram, Slack

If per-platform: ask for each enabled platform's template separately.

Step 6: Write Configuration

Read or create ~/.claude/omc_config.hook.json and merge the new settings:

{
  "version": 1,
  "enabled": true,
  "events": {
    "<event-name>": {
      "enabled": true,
      "template": "<user-provided-template>",
      "platforms": {
        "discord": { "template": "<discord-specific>" },
        "telegram": { "template": "<telegram-specific>" }
      }
    }
  }
}

Step 7: Validate and Test

Validate the template using validateTemplate() to check for unknown variables. If any are found, warn the user and offer to correct.

Offer to send a test notification with the new template.

Example Config

{
  "version": 1,
  "enabled": true,
  "events": {
    "session-end": {
      "enabled": true,
      "template": "Session {{sessionId}} ended after {{duration}}. Reason: {{reasonDisplay}}",
      "platforms": {
        "discord": {
          "template": "**Session Complete** | `{{projectDisplay}}` | {{duration}} | {{reasonDisplay}}"
        },
        "telegram": {
          "template": "Done: {{projectDisplay}} ({{duration}})\n{{#if contextSummary}}Summary: {{contextSummary}}{{/if}}"
        }
      }
    },
    "ask-user-question": {
      "enabled": true,
      "template": "{{#if question}}{{question}}{{/if}}\nWaiting for input on {{projectDisplay}}"
    }
  }
}
