codex-listener 0.1.2

A daemon that lets AI agents orchestrate OpenAI Codex CLI tasks

Codex-Listener

A daemon that lets AI agents (Claude, ChatGPT, etc.) orchestrate OpenAI Codex CLI tasks. Submit coding tasks, track progress, and collect results — all through simple shell commands that any AI can call.

Architecture

AI Agent  ──  scripts/*.py (submit)  ──▶  codex-listener daemon (FastAPI)
User     ◀── Feishu Bot card                              │
                                                          │ subprocess
                                                          ▼
                                                  codex exec --json --full-auto

AI agents run standalone Python scripts via their shell tool. Each script talks to the daemon over HTTP on localhost and prints structured JSON to stdout. No curl or HTTP knowledge needed in prompts.

Installation

# From source (Recommend)
uv pip install -e .

# From PyPI
uv tool install codex-listener

# Verify
codex-listener --version

Requires Python 3.10+ and OpenAI Codex CLI on PATH.

Quick Start

# Start the daemon
uv run codex-listener start

# Submit a task (fire-and-forget — daemon notifies user via Feishu on completion)
python3 skills/Codex-Listener/scripts/submit.py --prompt "fix the bug in auth.py" --cwd /path/to/project

# Stop the daemon
uv run codex-listener stop

Daemon Management

uv run codex-listener start [--port 19823] [--host 127.0.0.1]   # Start daemon
uv run codex-listener stop                                        # Stop daemon
uv run codex-listener status                                      # Check if running
uv run codex-listener logs [-f] [-n 50]                           # View logs

AI Skill Scripts

Standalone Python scripts in skills/Codex-Listener/scripts/ for AI agents to submit tasks to the daemon. All output a single JSON object to stdout. Exit code 0 = success, 1 = error. The daemon notifies the user via Feishu Bot on completion.

python3 skills/Codex-Listener/scripts/submit.py --prompt "..." [--model gpt-5.3-codex] [--cwd .] [--sandbox workspace-write]
python3 skills/Codex-Listener/scripts/status.py --task-id <id>
python3 skills/Codex-Listener/scripts/list_tasks.py [--status running]
python3 skills/Codex-Listener/scripts/cancel.py --task-id <id>
python3 skills/Codex-Listener/scripts/health.py

Configuration

Config file: ~/.codex-listener/config.json (auto-created on first run).

{
  "feishu": {
    "enabled": true,
    "appId": "cli_xxxx",
    "appSecret": "xxxxx",
    "encryptKey": "",
    "verificationToken": "",
    "allowFrom": ["ou_xxxx"]
  },
  "telegram": {
    "enabled": false,
    "token": "",
    "allowFrom": [],
    "proxy": null
  },
  "qq": {
    "enabled": false,
    "appId": "YOUR_APP_ID",
    "secret": "YOUR_APP_SECRET",
    "allowFrom": []
  }
}

feishu — Feishu Bot notification settings. When a task completes or fails, the daemon parses the Codex session JSONL (extracting the last assistant message, token usage, and completion time) and sends an interactive card to the configured recipients.

Field	Description
enabled	Set to true to enable Feishu notifications
appId	Feishu app ID (from Feishu Open Platform)
appSecret	Feishu app secret
encryptKey	Event encryption key (optional, for webhook verification)
verificationToken	Event verification token (optional)
allowFrom	List of Feishu open_ids to receive notifications

telegram — Telegram Bot notification settings. Similar to Feishu, sends formatted messages when tasks complete or fail.

Field	Description
enabled	Set to true to enable Telegram notifications
token	Telegram Bot token (from @BotFather)
allowFrom	List of Telegram chat IDs to receive notifications (Get from NanoBot console)
proxy	Optional HTTP/HTTPS proxy URL (e.g., "http://proxy.example.com:8080")

qq — QQ Bot notification settings using Botpy SDK. Sends formatted messages to users when tasks complete or fail.

Field	Description
enabled	Set to true to enable QQ notifications
appId	QQ Bot application ID (from QQ Open Platform)
secret	QQ Bot application secret
allowFrom	List of user openids to receive notifications

AI Integration

Copy the skill file for your AI tool:

• Claude Code: Copy skills/Codex-Listener/SKILL.md to your project's .claude/skills/ directory.
• NanoBot: Copy skills/Codex-Listener/SKILL.md to your nanobot's Workspace skills/ directory.

The skill file teaches the AI how to use the Python scripts in skills/Codex-Listener/scripts/.
