Telegram Bot

Agent AFK can run as a Telegram bot, giving you a private chat interface backed by the same session manager and full tool set as the REPL. You can also use Telegram as a notification channel — the daemon pushes a message whenever a scheduled task completes.

Setup

1. Create a bot token

Open Telegram and message @BotFather:

1. Send /newbot
2. Follow the prompts to name your bot
3. Copy the token BotFather gives you (it looks like 1234567890:ABC...)

2. Run the setup wizard

afk telegram setup

The wizard validates your token against the Telegram API, then walks you through discovering your chat ID (send your bot a message and it polls for it automatically), and writes both to ~/.afk/config/afk.env:

TELEGRAM_BOT_TOKEN=1234567890:ABC...
AFK_TELEGRAM_ALLOWED_CHAT_IDS=12345678

3. Start the bot

afk telegram start

The bot starts as a background daemon and logs to ~/.afk/logs/telegram.log.

Manual configuration

Skip the wizard by setting the env vars directly in ~/.afk/config/afk.env or your shell profile:

export TELEGRAM_BOT_TOKEN=1234567890:ABC...
export AFK_TELEGRAM_ALLOWED_CHAT_IDS=12345678

AFK_TELEGRAM_ALLOWED_CHAT_IDS is a comma-separated list of chat IDs whose messages the bot will accept. Messages from any other chat are silently ignored. You must set at least one ID or the bot will start but never respond.

To allow multiple users:

AFK_TELEGRAM_ALLOWED_CHAT_IDS=12345678,87654321

Bot commands

Inside Telegram, the bot recognizes:

Any other message is sent to the session as a regular turn. The bot has full tool access via bypass mode — same as the REPL.

Managing the bot process

afk telegram start       # start as a background daemon
afk telegram stop        # SIGTERM (then SIGKILL after 5 seconds)
afk telegram restart     # stop + start
afk telegram status      # running state, PID, uptime, memory, recent log lines
afk telegram logs        # print the last 50 log lines
afk telegram logs -f     # follow the log (like tail -f)
afk telegram logs -n 100 # show the last 100 lines

afk telegram status shows:

• Running / stopped state with PID
• Uptime (when running)
• Memory usage in MB (when running)
• Path to the PID file and log file
• Recent log entries

Telegram as a notification channel

Even without the interactive bot surface, you can use Telegram purely for push notifications. The daemon pushes a message to AFK_TELEGRAM_ALLOWED_CHAT_IDS on every task completion. The send_telegram tool is also available inside agent sessions — any agent session can push a notification to your phone when work finishes.

The send_telegram tool is safe to attempt unconditionally: if Telegram is not configured, it returns an error instead of crashing.

Troubleshooting

Bot starts but never responds — the most common cause is a missing or incorrect AFK_TELEGRAM_ALLOWED_CHAT_IDS. Run afk telegram status and check the log with afk telegram logs. Send your bot a message, then check the log for "message from unknown chat" or similar.

afk telegram start exits immediately — the bot process crashed on startup. Check the logs:

afk telegram logs

Common causes: invalid TELEGRAM_BOT_TOKEN, network connectivity, or a port conflict.

Token not set — afk telegram setup reads from and writes to ~/.afk/config/afk.env. If you set the token in your shell profile, it may not be available to the bot daemon. Write it to afk.env instead — afk config env set prompts for the token with a masked input so it never lands in your shell history:

afk config env set TELEGRAM_BOT_TOKEN          # masked prompt (recommended)
echo "TELEGRAM_BOT_TOKEN=<token>" >> ~/.afk/config/afk.env   # or append by hand
