Eidos: Git-Native AI Software Development Ecosystem

Eidos is an open, Git-native, agent-agnostic development framework designed to unify product definition, architectural invariants, and autonomous coding agents under executable living specifications.

This repository dogfoods the Eidos Specification Standard to define Eidos itself.

Quickstart

# Install with uv (recommended)
uv add --dev eidos-ai

# Or with pip
pip install eidos-ai

# Initialize Eidos in your repository
eidos init

# Validate living specifications
eidos validate eidos

# Verify zero drift between code and living specs
eidos drift

# Launch interactive C4 architecture portal
eidos serve --path eidos --port 8080

# Install AI agent plugin (13 skills for Antigravity, Claude, Cursor, Copilot)
eidos plugin install --target all
