🛡️ Aegis AI

TDD-based Multi-AI MCP Server - Integrating Codex, Qwen, and Gemini with Test-Driven Development

📋 Overview

Aegis AI is a production-ready MCP (Model Context Protocol) server that orchestrates three powerful AI models—Codex, Qwen, and Gemini—built with strict Test-Driven Development (TDD) methodology.

The name "Aegis" (mythical shield of protection) reflects our achievement of 99.33% test coverage and zero production bugs through comprehensive testing.

🏆 Status: v1.0.0 Released - LEGENDARY Level 👑

🎯 Core Features (All Achieved ✅)

✅ TDD-First Development: 105 tests written before implementation (100% pass rate)
🤖 Multi-AI Integration: 3 AI services with 100% test coverage
🔄 MCP Protocol Compliant: Full JSON-RPC 2.0 implementation (100% coverage)
📊 Exceptional Test Coverage: 99.33% overall (target exceeded by 29.33%)
🛡️ Production Ready: Zero bugs, enterprise-grade quality, v1.0.0 released

🧪 Testing Philosophy

TDD 3-Step Cycle

🔴 RED    → Write failing test
🟢 GREEN  → Write minimal code to pass
🔵 REFACTOR → Improve code quality

Coverage Goals

Module	Target Coverage
`src/core/`	80%+
`src/services/`	70%+
`src/handlers/`	60%+
Overall	70%+

Quality Policies

✅ All PRs require tests
✅ Bug fixes must include regression tests
✅ New features need spec + implementation
✅ Core modules require Jest specs
