# 🤖 AACode - CLI Programming Agent

[![Python Version](https://img.shields.io/badge/python-3.12+-blue.svg)](https://python.org)

> 🚀 **AI Programming CLI Agent based on DeepSeek** - A lightweight ReAct architecture that borrows and adopts advanced concepts from current popular Agents, 100% python.

## Design Principles
* Less scaffolding, more trust in models: simple core logic, relying on model capabilities
* File-based context: dynamic discovery, Markdown files as primary storage
* Bash universal adapter: flexible system access through safety guardrails
* Context management: smart reduction strategies borrowed from Cursor and Manus
* Asynchronous design: all blocking operations are asynchronous
* Layered tool system: atomic tools, management tools, Skills three-layer architecture
* Safety guardrails: comprehensive command and path security checks
* Extensible architecture: support for custom tools and model backends

## 🎯 Quick Start
### Operating System
This project is primarily developed and tested on Linux and MacOS. It is recommended to use Linux or MacOS. Windows users may encounter Python path issues; please configure accordingly.

### One-Click Initialization

```bash
git clone https://github.com/kandada/aacode.git
cd aacode
python3 init.py  # Python 3.12 or higher is recommended
# Check if the .venv environment is activated; if not, run:
source .venv/bin/activate
```

### Getting Started
**Note**: Before starting a task, you can create an `init.md` file in your task directory as a detailed task description file. The more detailed your design ideas, the better results you can get.

```bash
# Using the convenient startup script
./run.sh -p examples/my_project "Your task description"

# Or run manually
source .venv/bin/activate
export LLM_API_KEY="your-api-key"
export LLM_API_URL="your-api-url"
export LLM_MODEL_NAME="your-model-name"
python3 main.py -p examples/my_project "Your task description"

# Advanced Mode
## Plan-First Mode
python main.py -p examples/my_project "Complex task" --plan-first
## Interactive Continuous Conversation
python main.py -p examples/my_project "Initial task" --interactive
## Specify Session
python main.py --session session_20250128_123456_0 "Continue task"
```

### Or pip Installation (Recommended)
After pip install, you can use the `aacode` command

```bash
# Install
pip install aacode

# Initialize configuration
aacode init

# Run
aacode run -p /your/project/path "your task"
```

|----------|---------------------------------------------------------------------------------------------------------|
| macOS (Apple Silicon) | [AACode_1.7.9_aarch64.dmg](https://github.com/kandada/aacode/raw/main/desktop/AACode_1.7.9_aarch64.dmg) |
| Windows | [AACode_1.7.9_x64-setup.exe](https://github.com/kandada/aacode/raw/main/desktop/AACode_1.7.9_x64-setup.exe) |

> The desktop client still requires Python and dependencies. See 👉 [DESKTOP.md](DESKTOP.md) for full setup instructions.

## 🔧 Configuration

### Large Language Model (supports deepseek, openai, etc., no pre-configuration required; users need to configure independently)
```bash
# OpenAI
export LLM_API_KEY="your-openai-key"
export LLM_API_URL="https://api.openai.com/v1"
export LLM_MODEL_NAME="gpt-4"
export LLM_GATEWAY="openai"
export LLM_MULTIMODAL="false"

# Other OpenAI API compatible models (deepseek, etc.)
export LLM_API_KEY="your-api-key"
export LLM_API_URL="https://your-api-endpoint/v1"
export LLM_MODEL_NAME="your-model-name"
export LLM_GATEWAY="openai"
export LLM_MULTIMODAL="false"

# Multimodal models (e.g., MiniMax, Kimi, etc.)
export LLM_API_KEY="your-kimi-key"
export LLM_API_URL="https://api.moonshot.cn/v1"
export LLM_MODEL_NAME="kimi-k2.5"
export LLM_GATEWAY="anthropic"
export LLM_MULTIMODAL="true"
```

### Multimodal Models
Supports various multimodal models (e.g., Kimi K2.5, MiniMax M2.5, etc.). Configure in .env file or aacode_config.yaml:
- `MULTIMODAL_API_KEY`: Multimodal model API key
- `MULTIMODAL_API_URL`: Multimodal model API address (optional, defaults to model-specific address)

### Search Engine
Currently only supports SearXNG. Users need to deploy their own and configure the URL in aacode_config.yaml, but it is recommended to configure via environment variable SEARCHXNG_URL.

### MCP
- Users can configure MCP resources (supporting stdio and sse) in aacode_config.yaml

### Adding/Removing Skills

Skills are placed under `aacode/skills/` directory. **No configuration file changes needed** — auto-discovered on restart.

#### Directory Structure
```
aacode/skills/<skill_name>/
├── SKILL.md    # Skill description (fastclaw template format)
└── main.py     # Implementation (public functions auto-registered as tools, excluding _ prefix and main)
```

#### SKILL.md Format
```markdown
## Description
Skill description. Required imports auto-injected.

## Parameters
- param1: Parameter 1 description
- param2: Parameter 2 description

## Example
run_skills("skill_name", {"param1": "value1", "param2": "value2"})
```

#### Examples
See `skills/pandas/`, `skills/numpy/`, `skills/playwright/`.

## 📋 Usage Examples

### Example 1: Create Hello World
```bash
./run.sh -p examples/hello_demo "Create a hello.py file with content print('Hello, World!')"
```

### Example 2: Develop Calculator
```bash
./run.sh -p examples/calculator "Create a calculator program supporting addition, subtraction, multiplication, and division with test cases"
```

### Example 3: Web Application Development
```bash
./run.sh -p examples/web_app "Create a simple Flask web application with home and about pages"
```

### Example 4: Data Processing
```bash
./run.sh -p examples/data_analysis "Create a data analysis script that reads CSV files in the project directory and generates statistical charts"
```

## 🎯 Best Practices

### 1. Clear Task Descriptions

✅ **Good description**:
```
"Create a Python program that uses the requests library to fetch weather API data
and saves the results to a weather.json file"
```

❌ **Poor description**:
```
"Make a weather program"
```

### 2. Execute Complex Tasks in Steps

For complex projects, execute in multiple steps:

```bash
# Step 1: Create basic structure
python3 main.py -p examples/app "Create Flask application basic structure"

# Step 2: Add features
python3 main.py -p examples/app "Add user authentication features"

# Step 3: Test
python3 main.py -p examples/app "Write tests for all features"
```

### 3. Use Project Guidelines

Edit the `init.md` file and add project-specific rules:

```markdown
# Project Guidelines

## Code Style
- Use PEP 8 standards
- Function names use snake_case
- Class names use PascalCase

## Testing Requirements
- Every feature must have unit tests
- Test coverage must be at least 80%

## Documentation Requirements
- All public functions must have docstrings
- README.md must include usage examples
```
