agy-telegram

agy-telegram

A bidirectional Telegram bridge for the Google Antigravity (agy) CLI. It connects to an active tmux session, allows remote command approval via inline keyboards, tracks agent turns in real time, and exposes a local Unix domain socket for system push notifications.

Design Principles

• Zero Inbound Ports: Operates exclusively through outbound HTTPS long-polling to the Telegram Bot API.
• Strict Authorization: Enforces user ID whitelisting across all text messages and inline query callbacks.
• Instant Buffer Injection: Uses tmux set-buffer and paste-buffer to paste large inputs atomically, avoiding character-by-character key lag.
• O(1) Turn Tailing: Watches transcript.jsonl using persistent byte-offset seeking, reading only new appended records without full file scans.
• Hardened Local IPC: Listens on a local Unix domain socket (/tmp/agy-sentinel.sock) with 0600 permissions and Linux peer credential validation (SO_PEERCRED) to prevent local spoofing.

Requirements

• Python 3.10+
• Linux (with systemd), macOS, or WSL2
• tmux installed and available in $PATH
• Google Antigravity CLI (agy) configured and accessible in $PATH

---

Installation

git clone https://github.com/kappino/agy-telegram.git
cd agy-telegram
pip install -e .

This installs two executable commands:

• agy-telegram: Main daemon and management CLI.
• agy-notify: Command-line tool to dispatch proactive alerts through the local IPC socket.

---

Configuration

Create the configuration directory and copy the template:

mkdir -p ~/.config/agy-telegram
cp config.example.toml ~/.config/agy-telegram/config.toml

Edit ~/.config/agy-telegram/config.toml:

[telegram]
bot_token = "123456789:ABCdefGhIJKlmNoPQRsTUVwxyZ"
allowed_users = [123456789] # Numeric Telegram user ID (from @userinfobot)

[agent]
executable = "agy"
default_workspace = "."
default_model = "gemini-3.8-flash"
default_effort = "high"
timeout_seconds = 600

[sentinel]
enabled = true
socket_path = "/tmp/agy-sentinel.sock"

[mirror]
enabled = true
mode = "tmux"
target_session = "main:0.0"
log_file = "/tmp/agy-telegram-chat.log"
check_interval_seconds = 1.0

Environment Variables: Alternatively, configure credentials via TELEGRAM_BOT_TOKEN and TELEGRAM_ALLOWED_USER_ID in a local .env file or environment variables.

---

Usage

1. Launch Antigravity inside tmux

tmux new -s main "agy"

2. Start the bridge daemon

agy-telegram start

3. Chat via Telegram

Open your bot in Telegram and send /start. Plain text messages sent to the chat will be forwarded into the active Antigravity session.

---

Bot Commands

When the agent prompts for confirmation (e.g. running a shell command), inline buttons (Approve and Reject) appear directly in the chat.

---

Local Push Alerts (agy-notify)

Local scripts, cron jobs, or monitoring hooks can trigger immediate push notifications to Telegram:

# Info level
agy-notify --level info --title "Backup" --message "Database backup completed successfully."

# Warning level
agy-notify --level warning --title "Memory" --message "RAM usage exceeded 85%."

# Critical alert
agy-notify --level alert --title "Service Offline" --message "Nginx process is not responding."

---

Running as a Systemd Service

To deploy agy-telegram as a persistent daemon on Linux:

sudo cp systemd/agy-telegram.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now agy-telegram
sudo systemctl status agy-telegram

The systemd unit includes security sandboxing directives (PrivateTmp=true, ProtectSystem=full, ProtectHome=read-only, and RuntimeDirectory=agy-telegram).
