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
• For SaaS: API key (OpenAI, Anthropic)

Installation

# 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)

# 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

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%
