## 🎯 Why Clawd Code?
**Clawd Code** is a **production-oriented Python rebuild of Claude Code**, ported from the **real TypeScript architecture** and shipped as a **working CLI agent**, not just a source dump.
- **Real Agent Runtime** — tool-calling loop, streaming REPL, session history, and multi-turn execution
- **High-Fidelity Port** — keeps the original Claude Code architecture while adapting it to idiomatic Python
- **Built to Hack On** — readable Python codebase, rich tests, and markdown-driven skill extensibility
**Token Streaming + Tool-Aware Agent Loop**
**Programmable Skill Runtime with Tool Sandboxing**
**Instant Web Fetch for External Context**
**Real CLI • Real Usage • Real Community**
**A real Claude Code-style terminal workflow in Python: stream replies, call tools, fetch context, and extend behavior with skills.**
**🚀 Try it now! Fork it, modify it, make it yours! Pull requests welcome!**

## ⭐ Star History
## ✨ Features
### Streaming Agent Experience
```text
>>> /stream on
>>> Explain tests/test_agent_loop.py
[streaming answer...]
• Read (tests/test_agent_loop.py) running...
↳ lines 1-180
>>> /render-last
```
- True API streaming for direct replies plus richer streaming during tool-driven agent loops
- Built-in `/stream` toggle for live output and `/render-last` for clean Markdown re-rendering on demand
- Designed for real terminal demos: streaming text, visible tool activity, and stable fallback behavior
### Programmable Skill Runtime
```md
---
description: Explain code with diagrams and analogies
allowed-tools:
- Read
- Grep
- Glob
arguments: [path]
---
Explain the code in $path. Start with an analogy, then draw a diagram.
```
- Markdown-based `SKILL.md` slash commands
- Supports project skills, user skills, named arguments, and tool limits
### Multi-Provider Support
```python
providers = ["Anthropic Claude", "OpenAI GPT", "Zhipu GLM"] # + easy to extend
```
### Interactive REPL
```text
>>> Hello!
Assistant: Hi! I'm Clawd Codex, a Python reimplementation...
>>> /help # Show commands
>>> / # Show all commands & skills
>>> /save # Save session
>>> /multiline # Multi-paragraph input
>>> Tab # Auto-complete
>>> /explain-code qsort.py # Run a skill
```
### Complete CLI
```bash
clawd # Start REPL
clawd login # Configure API
clawd --version # Check version
clawd config # View settings
```

## 🚀 Quick Start
### Install
```bash
git clone https://github.com/GPT-AGI/Clawd-Code.git
cd Clawd-Code
# Create venv (uv recommended)
uv venv --python 3.11
source .venv/bin/activate
# Install
uv pip install -r requirements.txt
```
### Configure
#### Option 1: Interactive (Recommended)
```bash
python -m src.cli login
```
This flow will:
1. ask you to choose a provider: anthropic / openai / glm
2. ask for that provider's API key
3. optionally save a custom base URL
4. optionally save a default model
5. set the selected provider as default
The configuration file is saved in in `~/.clawd/config.json`. Example structure:
```json
{
"default_provider": "glm",
"providers": {
"anthropic": {
"api_key": "base64-encoded-key",
"base_url": "https://api.anthropic.com",
"default_model": "claude-sonnet-4-20250514"
},
"openai": {
"api_key": "base64-encoded-key",
"base_url": "https://api.openai.com/v1",
"default_model": "gpt-4"
},
"glm": {
"api_key": "base64-encoded-key",
"base_url": "https://open.bigmodel.cn/api/paas/v4",
"default_model": "glm-4.5"
}
}
}
```
### Run
```bash
python -m src.cli # Start REPL
python -m src.cli --help # Show help
```
**That's it!** Start chatting with AI in 3 steps.

## 💡 Usage
### REPL Commands
| Command | Description |
| ------------ | --------------------- |
| `/` | Show commands & skills |
| `/help` | Show all commands |
| `/save` | Save session |
| `/load ` | Load session |
| `/multiline` | Toggle multiline mode |
| `/clear` | Clear history |
| `/exit` | Exit REPL |
### Skills (Slash Commands)
Skills are markdown-based slash commands stored under `.clawd/skills`. Each skill lives in its own directory and must be named `SKILL.md`.
**1) Create a project skill**
Create:
```text
/.clawd/skills//SKILL.md
```
Example:
```md
---
description: Explains code with diagrams and analogies
when_to_use: Use when explaining how code works
allowed-tools:
- Read
- Grep
- Glob
arguments: [path]
---
Explain the code in $path. Start with an analogy, then draw a diagram.
```
**2) Use it in the REPL**
```text
❯ /
❯ /
```
Example:
```text
❯ /explain-code qsort.py
```
**Notes**
- User-level skills: `~/.clawd/skills//SKILL.md`
- Tool limits: `allowed-tools` controls which tools the skill can use.
- Arguments: use `$ARGUMENTS`, `$0`, `$1`, or named args like `$path` (from `arguments`).
- Placeholder syntax: use `$path`, not `${path}`.
