# GOATCODE - Production-Grade Coding Agent

A **deterministic, tool-augmented, autonomous coding agent** that beats prompt-only solutions through real architecture.

## 🎯 The 80% That Matters

Unlike other AI coding assistants that rely on prompts alone, GOATCODE implements:

1. **🔍 File Indexing Engine** - AST-based semantic code search with vector embeddings
2. **🧠 Context Injection** - Automatic relevance-based retrieval with token budget management
3. **🔄 Test→Fix→Retry Loop** - Iterative validation with automatic error recovery
4. **📊 Diff-Based Patching** - AST-aware minimal surgical edits (no full rewrites)
5. **💰 Token Budget Manager** - Dynamic context window optimization
6. **🗄️ Memory System** - Resolution pattern storage and retrieval

**Prompt = 20%. Architecture = 80%**

## 🚀 Quick Start

### Prerequisites

- Python 3.9+
- For local models: [Ollama](https://ollama.com)
- For SaaS: API key (OpenAI, Anthropic)

### Installation

```bash
# Clone repository
git clone https://github.com/yourusername/goatcode.git
cd goatcode

# Install dependencies
pip install -r requirements.txt

# If using Ollama, pull a model
ollama pull llama2
ollama pull codellama
```

### Usage

#### Interactive Mode (Recommended)

```bash
# With local Ollama
python -m goatcode --provider ollama --model llama2

# With OpenAI
python -m goatcode --provider openai --model gpt-4 --api-key $OPENAI_API_KEY

# With Anthropic
python -m goatcode --provider anthropic --model claude-3-opus
```

#### Batch Mode

```bash
python -m goatcode --provider ollama \
  -p "Create a Python function to parse JSON with error handling" \
  -o result.json
```

### Example Session

📝 > Create a REST API endpoint for user authentication with JWT

🚀 Starting execution...

============================================================
Status: SUCCESS
============================================================

📊 Analysis Summary:
Creating a secure REST API endpoint for user authentication 
using JWT tokens. Will include login, registration, and 
protected route middleware.

📋 Implementation Plan:
  1. Create auth module with JWT utilities
  2. Implement login endpoint with password hashing
  3. Implement registration endpoint with validation
  4. Create authentication middleware
  5. Add comprehensive error handling

📝 Files Modified:
  [CREATE] src/auth/jwt_utils.py
  [CREATE] src/auth/endpoints.py
  [CREATE] src/auth/middleware.py
  [UPDATE] requirements.txt

✅ Validation Report:
  ✓ All validations passed
  ✓ Type checking clean
  ✓ Tests passing (12/12)

🎯 Confidence Score: 95%
