## What is this?

**nanoclaw-py** is a personal AI Agent powered by the **Claude Agent SDK**, communicating with you via **Telegram**. It can read/write files, execute commands, search the web, and schedule tasks — all in **~500 lines of Python**.

nanoclaw-py is a Python reinterpretation of the original NanoClaw idea, using Telegram as the messaging channel (instead of WhatsApp) with a focus on simplicity. This project is part of the [ApeCode.ai](https://apecode.ai) learning series.
> This project is heavily inspired by [**nanoclaw**](https://github.com/gavrielc/nanoclaw) — a brilliant, minimal Claude agent by [@gavrielc](https://github.com/gavrielc).

```
You: @Ape Write a Python script to scrape Hacker News headlines
Ape: Sure, let me create that script...
     ✅ Created workspace/hn_scraper.py

You: @Ape Run it every day at 9am and send me the results
Ape: ✅ Scheduled task created (cron: 0 9 * * *)
     I'll run the script and send you results daily at 9:00
```

### Data Flow

## 🚀 Quick Start

### Prerequisites

- Python 3.12+
- [uv](https://docs.astral.sh/uv/) package manager
- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) installed
- Telegram Bot Token (from [@BotFather](https://t.me/BotFather))
- Anthropic API Key

### 1. Clone the repo

```bash
git clone https://github.com/ApeCodeAI/nanoclaw-py.git
cd nanoclaw-py
```

### 2. Install dependencies

```bash
uv sync
```

### 3. Configure environment

```bash
cp .env.example .env
```

Edit `.env` with your credentials:

```bash
TELEGRAM_BOT_TOKEN=your_bot_token      # From @BotFather
OWNER_ID=your_telegram_user_id          # From @userinfobot
ANTHROPIC_API_KEY=your_anthropic_api_key
```

> 💙 **Sponsored by [BytePass](https://bytepass.ai)** — one API key for Claude, GPT, Gemini, and 50+ models. To use its Anthropic-compatible endpoint, set `ANTHROPIC_BASE_URL=https://api.bytepass.ai` and use your BytePass API key. BytePass is optional; the official Anthropic API and other compatible endpoints also work.

### 4. Run

```bash
uv run python -m nanoclaw
```

Open Telegram, send a message to your bot, and start chatting!

## ❓ FAQ

<details>
<summary><b>How do I get my Telegram user ID?</b></summary>

Search for `@userinfobot` on Telegram and send any message. It will reply with your user ID.

</details>

<details>
<summary><b>Why single-user only?</b></summary>

This is an educational project. The `OWNER_ID` restriction ensures only you can use it. The Agent has Bash execution privileges — exposing it publicly would be a security risk.

</details>

<details>
<summary><b>Does the session persist after restart?</b></summary>

Yes. Session is persisted via `session_id` in `data/state.json` and auto-restored on restart. Long-term memory in `workspace/CLAUDE.md` survives even `/clear` commands.

</details>

<details>
<summary><b>Do scheduled tasks survive restart?</b></summary>

Yes. Tasks are stored in SQLite and the scheduler automatically picks up due tasks after restart.

</details>

<details>
<summary><b>Can I use a proxy or custom API endpoint?</b></summary>

Yes. Set `ANTHROPIC_BASE_URL` to your proxy address. It must be compatible with the Anthropic Messages API format.

</details>

```
你: @Ape 帮我写一个 Python 脚本，爬取 Hacker News 首页标题
Ape: 好的，我来创建这个脚本...
     ✅ 已创建 workspace/hn_scraper.py

你: @Ape 每天早上 9 点运行一次，把结果发给我
Ape: ✅ 已创建定时任务 (cron: 0 9 * * *)
     每天 9:00 我会运行脚本并把结果发到这里
```

## 快速开始

### 前置条件

- Python 3.12+
- [uv](https://docs.astral.sh/uv/) 包管理器
- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) 已安装
- Telegram Bot Token（[@BotFather](https://t.me/BotFather) 获取）
- Anthropic API Key

### 安装步骤

```bash
# 1. 克隆项目
git clone https://github.com/ApeCodeAI/nanoclaw-py.git
cd nanoclaw-py

# 2. 安装依赖
uv sync

# 3. 配置环境变量
cp .env.example .env
# 编辑 .env 填入你的 Token 和 API Key

# 可选：使用 BytePass 等兼容 Anthropic API 的服务
# ANTHROPIC_BASE_URL=https://api.bytepass.ai

# 4. 启动
uv run python -m nanoclaw
```

打开 Telegram，给你的 Bot 发送消息，开始对话！

### 配置说明

| 变量 | 必填 | 默认值 | 说明 |
|------|------|--------|------|
| `TELEGRAM_BOT_TOKEN` | ✅ | — | Telegram Bot Token |
| `OWNER_ID` | ✅ | — | 你的 Telegram 用户 ID |
| `ANTHROPIC_API_KEY` | ✅ | — | Anthropic API Key |
| `ANTHROPIC_BASE_URL` | — | 官方 | 自定义 API 端点（代理/网关） |
| `ASSISTANT_NAME` | — | `Ape` | 助手名称 |

> **获取用户 ID**：在 Telegram 搜索 `@userinfobot`，发送任意消息即可获取。

## 常见问题

<details>
<summary><b>可以用国内 API 代理吗？</b></summary>

可以。设置 `ANTHROPIC_BASE_URL` 为你的代理地址即可，需兼容 Anthropic Messages API 格式。

</details>

<details>
<summary><b>重启后会话还在吗？</b></summary>

会话通过 `session_id` 持久化到 `data/state.json`，重启后自动恢复。长期记忆保存在 `workspace/CLAUDE.md`，即使 `/clear` 重置会话也不会丢失。

</details>

<details>
<summary><b>为什么只支持单用户？</b></summary>

这是一个教学项目，通过 `OWNER_ID` 限制只有你自己可以使用。Agent 拥有 Bash 执行权限，开放给公众会有安全风险。

</details>
