Channel Messaging

OrcBot provides unified messaging across Telegram, WhatsApp, Discord, Slack, email, and a web gateway. All skills auto-detect the source channel and handle delivery seamlessly.

- Otherwise → Telegram

Platform Differences:

Example:

{
  "skill": "send_voice_note",

    "channel": "telegram",
    "size": "1024x1024",
    "caption": "Here's your generated image"

Always use send_image instead of generate_image + send_file. The compound skill prevents duplicates and provides atomic operations.

Telegram Rich Features

telegram_send_buttons

Send message with inline keyboard buttons. Parameters:

string | number

required

Telegram chat ID

string

required

Message text

array

required

2D array of button objects. Each button has text and callback_data or url.

Button Format:

buttons: [
  [
    { text: "Yes", callback_data: "yes" },
    { text: "No", callback_data: "no" }
  ],
  [
    { text: "Learn More", url: "https://example.com" }
  ]
]

Example:

{
  "skill": "telegram_send_buttons",
  "args": {
    "chatId": "123456789",
    "message": "Do you approve this deployment?",
    "buttons": [
      [{"text": "Approve", "callback_data": "approve"}, {"text": "Deny", "callback_data": "deny"}],
      [{"text": "View Changes", "url": "https://github.com/org/repo/pull/123"}]
    ]
  }
}

Auto-coercion: If you pass a 1D array of button objects, the system auto-wraps each button in its own row:

"buttons": [{"text": "A", "callback_data": "a"}, {"text": "B", "callback_data": "b"}]
// Auto-converted to: [[{"text": "A", ...}], [{"text": "B", ...}]]

telegram_send_poll

Create a native Telegram poll. Parameters:

string | number

required

Telegram chat ID

string

required

Poll question

array

required

Array of 2-10 option strings

boolean

default:"true"

Whether votes are anonymous

boolean

default:"false"

Allow multiple selections

Example:

{
  "skill": "telegram_send_poll",
  "args": {
    "chatId": "123456789",
    "question": "Which deployment time works best?",
    "options": ["6 PM EST", "8 PM EST", "10 PM EST"],
    "isAnonymous": false
  }
}

telegram_edit_message

Edit a previously sent message. Parameters:

string | number

required

Telegram chat ID

number

required

Message ID from send_telegram or telegram_send_buttons

string

required

Updated message text

Example:

{
  "skill": "telegram_edit_message",
  "args": {
    "chatId": "123456789",
    "messageId": 54321,
    "newText": "Deployment complete! ✅"
  }
}

Use Case: Live progress updates without spam:

// Send initial message
send_telegram(chatId, "Deploying...")
// Returns: message_id 54321

// Update progress
telegram_edit_message(chatId, 54321, "Deploying... 50%")
telegram_edit_message(chatId, 54321, "Deploying... 100%")
telegram_edit_message(chatId, 54321, "Deployment complete! ✅")

telegram_react

React to a message with an emoji. Parameters:

string | number

required

Telegram chat ID

number

required

Message ID to react to

  "args": {
    "chatId": "123456789",
    "messageId": 54321,
    "emoji": "🔥"
  }
}

Graceful Degradation: Telegram restricts bots from setting native reactions in most chat types. The skill automatically falls back to replying with the emoji:

Reacted with 🔥 via reply (native reaction unavailable for bots in this chat type)

Native reactions only work in channels where the bot is admin.

Cross-Channel Reactions

eyes → 👀
thinking → 🤔

Best Practices

Channel selection priority:

Use auto-detection when replying to messages
Set explicit channel parameter for proactive sends
Let the system fall back to configured channels

Avoid cross-channel sends without permission. Autonomy mode blocks cross-channel messaging unless the tool is exempt (like send_email) or the user is an admin.
