z3ed is a command-line interface for YAZE that enables AI-driven ROM modifications through a proposal-based workflow. It provides both human-accessible commands for developers and machine-readable APIs for LLM integration, forming the backbone of an agentic development ecosystem.

This directory contains the primary documentation for the z3ed system.

Quick Start

Build z3ed

# Basic build (without GUI automation support)
cmake --build build --target z3ed

# Build with gRPC support (for GUI automation)
cmake -B build-grpc-test -DYAZE_WITH_GRPC=ON
cmake --build build-grpc-test --target z3ed

Common Commands

# Create an agent proposal in a safe sandbox
z3ed agent run --prompt "Make all soldier armor red" --rom=zelda3.sfc --sandbox

# List all active and past proposals
z3ed agent list

# View the changes for the latest proposal
z3ed agent diff

# Run an automated GUI test (requires test harness to be running)
z3ed agent test --prompt "Open the Overworld editor and verify it loads"
