Add Agent Swarm to Telegram

This skill adds Agent Teams (Swarm) support to an existing Telegram channel. Each subagent in a team gets its own bot identity in the Telegram group, so users can visually distinguish which agent is speaking.

Prerequisite: Telegram must already be set up via the /add-telegram skill. If src/telegram.ts does not exist or TELEGRAM_BOT_TOKEN is not configured, tell the user to run /add-telegram first.

How It Works

• The main bot receives messages and sends lead agent responses (already set up by /add-telegram)
• Pool bots are send-only — each gets a Grammy Api instance (no polling)
• When a subagent calls send_message with a sender parameter, the host assigns a pool bot and renames it to match the sender's role
• Messages appear in Telegram from different bot identities

Subagent calls send_message(text: "Found 3 results", sender: "Researcher")
  → MCP writes IPC file with sender field
  → Host IPC watcher picks it up
  → Assigns pool bot #2 to "Researcher" (round-robin, stable per-group)
  → Renames pool bot #2 to "Researcher" via setMyName
  → Sends message via pool bot #2's Api instance
  → Appears in Telegram from "Researcher" bot

Prerequisites

1. Create Pool Bots

Tell the user:

I need you to create 3-5 Telegram bots to use as the agent pool. These will be renamed dynamically to match agent roles.

1. Open Telegram and search for @BotFather
2. Send /newbot for each bot:
   • Give them any placeholder name (e.g., "Bot 1", "Bot 2")
   • Usernames like myproject_swarm_1_bot, myproject_swarm_2_bot, etc.
3. Copy all the tokens
4. Add all bots to your Telegram group(s) where you want agent teams

Wait for user to provide the tokens.

2. Disable Group Privacy for Pool Bots

Tell the user:

Important: Each pool bot needs Group Privacy disabled so it can send messages in groups.

For each pool bot in @BotFather:

1. Send /mybots and select the bot
2. Go to Bot Settings > Group Privacy > Turn off

Then add all pool bots to your Telegram group(s).

Implementation

Step 1: Update Configuration

Read src/config.ts and add the bot pool config near the other Telegram exports:

export const TELEGRAM_BOT_POOL = (process.env.TELEGRAM_BOT_POOL || '')
  .split(',')
  .map((t) => t.trim())
  .filter(Boolean);

Step 2: Add Bot Pool to Telegram Module

Read src/telegram.ts and add the following:

1. Update imports — add Api to the Grammy import:

import { Api, Bot } from 'grammy';

2. Add pool state after the existing let bot declaration:

// Bot pool for agent teams: send-only Api instances (no polling)
const poolApis: Api[] = [];
// Maps "{groupFolder}:{senderName}" → pool Api index for stable assignment
const senderBotMap = new Map<string, number>();
let nextPoolIndex = 0;

3. Add pool functions — place these before the isTelegramConnected function:

/**
 * Initialize send-only Api instances for the bot pool.
 * Each pool bot can send messages but doesn't poll for updates.
 */
export async function initBotPool(tokens: string[]): Promise<void> {
  for (const token of tokens) {
    try {
      const api = new Api(token);
      const me = await api.getMe();
      poolApis.push(api);
      logger.info(
        { username: me.username, id: me.id, poolSize: poolApis.length },
        'Pool bot initialized',
      );
    } catch (err) {
      logger.error({ err }, 'Failed to initialize pool bot');
    }
  }
  if (poolApis.length > 0) {
    logger.info({ count: poolApis.length }, 'Telegram bot pool ready');
  }
}

/**
 * Send a message via a pool bot assigned to the given sender name.
 * Assigns bots round-robin on first use; subsequent messages from the
 * same sender in the same group always use the same bot.
 * On first assignment, renames the bot to match the sender's role.
 */
export async function sendPoolMessage(
  chatId: string,
  text: string,
  sender: string,
  groupFolder: string,
): Promise<void> {
  if (poolApis.length === 0) {
    // No pool bots — fall back to main bot
    await sendTelegramMessage(chatId, text);
    return;
  }

  const key = `${groupFolder}:${sender}`;
  let idx = senderBotMap.get(key);
  if (idx === undefined) {
    idx = nextPoolIndex % poolApis.length;
    nextPoolIndex++;
    senderBotMap.set(key, idx);
    // Rename the bot to match the sender's role, then wait for Telegram to propagate
    try {
      await poolApis[idx].setMyName(sender);
      await new Promise((r) => setTimeout(r, 2000));
      logger.info({ sender, groupFolder, poolIndex: idx }, 'Assigned and renamed pool bot');
    } catch (err) {
      logger.warn({ sender, err }, 'Failed to rename pool bot (sending anyway)');
    }
  }

  const api = poolApis[idx];
  try {
    const numericId = chatId.replace(/^tg:/, '');
    const MAX_LENGTH = 4096;
    if (text.length <= MAX_LENGTH) {
      await api.sendMessage(numericId, text);
    } else {
      for (let i = 0; i < text.length; i += MAX_LENGTH) {
        await api.sendMessage(numericId, text.slice(i, i + MAX_LENGTH));
      }
    }
    logger.info({ chatId, sender, poolIndex: idx, length: text.length }, 'Pool message sent');
  } catch (err) {
    logger.error({ chatId, sender, err }, 'Failed to send pool message');
  }
}

Step 3: Add sender Parameter to MCP Tool

Read container/agent-runner/src/ipc-mcp-stdio.ts and update the send_message tool to accept an optional sender parameter:

Change the tool's schema from:

{ text: z.string().describe('The message text to send') },

To:

{
  text: z.string().describe('The message text to send'),
  sender: z.string().optional().describe('Your role/identity name (e.g. "Researcher"). When set, messages appear from a dedicated bot in Telegram.'),
},

And update the handler to include sender in the IPC data:

async (args) => {
    const data: Record<string, string | undefined> = {
      type: 'message',
      chatJid,
      text: args.text,
      sender: args.sender || undefined,
      groupFolder,
      timestamp: new Date().toISOString(),
    };

    writeIpcFile(MESSAGES_DIR, data);

    return { content: [{ type: 'text' as const, text: 'Message sent.' }] };
  },

Step 4: Update Host IPC Routing

Read src/ipc.ts and make these changes:

1. Add imports — add sendPoolMessage and initBotPool from the Telegram swarm module, and TELEGRAM_BOT_POOL from config.

2. Update IPC message routing — in src/ipc.ts, find where the sendMessage dependency is called to deliver IPC messages (inside processIpcFiles). The sendMessage is passed in via the IpcDeps parameter. Wrap it to route Telegram swarm messages through the bot pool:

if (data.sender && data.chatJid.startsWith('tg:')) {
  await sendPoolMessage(
    data.chatJid,
    data.text,
    data.sender,
    sourceGroup,
  );
} else {
  await deps.sendMessage(data.chatJid, data.text);
}

Note: The assistant name prefix is handled by formatOutbound() in the router — Telegram channels have prefixAssistantName = false so no prefix is added for tg: JIDs.

3. Initialize pool in main() in src/index.ts — after creating the Telegram channel, add:

if (TELEGRAM_BOT_POOL.length > 0) {
  await initBotPool(TELEGRAM_BOT_POOL);
}

Step 5: Update CLAUDE.md Files

5a. Add global message formatting rules

Read groups/global/CLAUDE.md and add a Message Formatting section:

## Message Formatting

NEVER use markdown. Only use WhatsApp/Telegram formatting:
- *single asterisks* for bold (NEVER **double asterisks**)
- _underscores_ for italic
- • bullet points
- ```triple backticks``` for code

No ## headings. No [links](url). No **double stars**.

5b. Update existing group CLAUDE.md headings

In any group CLAUDE.md that has a "WhatsApp Formatting" sectio
