takopi

🐙 A little helper from Happy Planet, here to make your Codex sessions happier-pi!

A Telegram bot that bridges messages to Codex sessions using non-interactive codex exec --json.

Features

• Stateless Resume: No database required—sessions are resumed via resume: <uuid> lines embedded in messages
• Progress Updates: Real-time progress edits showing commands, tools, and elapsed time
• Markdown Rendering: Full Telegram-compatible markdown with entity support
• Concurrency: Handles multiple conversations with per-session serialization
• Token Redaction: Automatically redacts Telegram tokens from logs

Quick Start

Prerequisites

• uv package manager
• Codex CLI on PATH

Installation

# Install with uv, then run as `takopi`
uv tool install takopi
takopi

# or run with uvx
uvx takopi

Setup

1. Start the bot: Send /start to your bot in Telegram—it can't message you until you do
2. Trust your working directory: Run codex once interactively in your project directory (must be a git repo) to add it to trusted directories

Configuration

Create ~/.codex/takopi.toml (or .codex/takopi.toml for a repo-local config):

bot_token = "123456789:ABCdefGHIjklMNOpqrsTUVwxyz"
chat_id = 123456789

Key	Description
bot_token	Telegram Bot API token from @BotFather
chat_id	Your Telegram user ID from @myidbot

The bridge only accepts messages where the chat ID equals the sender ID and both match chat_id (i.e., private chat with that user).

Codex Profile (Optional)

Create a Codex profile in ~/.codex/config.toml:

[profiles.takopi]
model = "gpt-5.2-codex"

Then run takopi with:

takopi --profile takopi

Options

Flag	Default	Description
--final-notify / --no-final-notify	--final-notify	Send final response as new message (vs. edit)
--debug / --no-debug	--no-debug	Enable verbose logging
--profile NAME	(codex default)	Codex profile name
--version		Show the version and exit

Usage

New Conversation

Send any message to your bot. The bridge will:

1. Send a silent progress message
2. Stream events from codex exec
3. Update progress every ~2 seconds
4. Send final response with session ID

Resume a Session

Reply to a bot message (containing resume: <uuid>), or include the resume line in your message:

resume: `019b66fc-64c2-7a71-81cd-081c504cfeb2`

Cancel a Run

Reply to a progress message with /cancel to stop the running execution.

Notes

• Startup: Pending updates are drained (ignored) on startup
• Progress: Updates are throttled to ~2s intervals, sent silently
• Filtering: Only accepts messages where chat ID equals sender ID and matches chat_id
• Single instance: Run exactly one instance per bot token—multiple instances will race for updates
