z3ed AI Agentic Plan - Current Status

Date: October 3, 2025
Overall Status: ✅ Infrastructure Complete | 🚀 Ready for Testing
Build Status: ✅ z3ed compiles successfully in build-grpc-test
Platform Compatibility: ✅ Windows builds supported (SSL optional, Ollama recommended)

Executive Summary

The z3ed AI agentic system infrastructure is fully implemented and ready for real-world testing. All four phases from the LLM Integration Plan are complete:

• ✅ Phase 1: Ollama local integration (DONE)
• ✅ Phase 2: Gemini API enhancement (DONE)
• ✅ Phase 4: Enhanced prompting with PromptBuilder (DONE)
• ⏭️ Phase 3: Claude integration (DEFERRED - not critical for initial testing)

🎯 What's Working Right Now

1. Build System ✅

• File Structure: Clean, modular architecture

  • test_common.{h,cc} - Shared utilities (134 lines)
  • test_commands.cc - Main dispatcher (55 lines)
  • ollama_ai_service.{h,cc} - Ollama integration (264 lines)
  • gemini_ai_service.{h,cc} - Gemini integration (239 lines)
  • prompt_builder.{h,cc} - Enhanced prompting (354 lines, refactored for tile16 focus)

• Build: Successfully compiles with gRPC + JSON support

• Platform Support:

  • ✅ macOS: Full support (OpenSSL auto-detected)
  • ✅ Linux: Full support (OpenSSL via package manager)
  • ✅ Windows: Build without gRPC/JSON or use Ollama (no SSL needed)

• Dependency Guards:

  • SSL only required when YAZE_WITH_GRPC=ON AND YAZE_WITH_JSON=ON
  • Graceful degradation: warns if OpenSSL missing but Ollama still works
  • Windows-compatible: can build basic z3ed without AI features

2. AI Service Infrastructure ✅

AIService Interface

Location: src/cli/service/ai_service.h

• Clean abstraction for pluggable AI backends
• Single method: GetCommands(prompt) → vector<string>
• Easy to test and swap implementations

Implemented Services

A. MockAIService (Testing)

• Returns hardcoded test commands
• Perfect for CI/CD and offline development
• No dependencies required

B. OllamaAIService (Local LLM)

• ✅ Full implementation complete
• ✅ HTTP client using cpp-httplib
• ✅ JSON parsing with nlohmann/json
• ✅ Health checks and model validation
• ✅ Configurable model selection
• ✅ Integrated with PromptBuilder for enhanced prompts
• Models Supported:
  • qwen2.5-coder:7b (recommended, fast, good code gen)
  • codellama:7b (alternative)
  • llama3.1:8b (general purpose)
  • Any Ollama-compatible model

C. GeminiAIService (Google Cloud)

• ✅ Full implementation complete
• ✅ HTTP client using cpp-httplib
• ✅ JSON request/response handling
• ✅ Integrated with PromptBuilder
• ✅ Configurable via GEMINI_API_KEY env var
• Models: gemini-1.5-flash, gemini-1.5-pro

3. Enhanced Prompting System ✅

PromptBuilder (src/cli/service/prompt_builder.{h,cc})

Features Implemented:

• ✅ System Instructions: Clear role definition for the AI
• ✅ Command Documentation: Inline command reference
• ✅ Few-Shot Examples: 8 curated tile16/dungeon examples (refactored Oct 3)
• ✅ Resource Catalogue: Extensible command registry
• ✅ JSON Output Format: Enforced structured responses
• ✅ Tile16 Reference: Inline common tile IDs for AI knowledge

Example Categories (UPDATED):

1. Overworld Tile16 Editing ⭐ PRIMARY FOCUS:

   • Single tile placement: "Place a tree at position 10, 20 on map 0"
   • Area creation: "Create a 3x3 water pond at coordinates 15, 10"
   • Path creation: "Add a dirt path from position 5,5 to 5,15"
   • Pattern generation: "Plant a row of trees horizontally at y=8 from x=20 to x=25"

2. Dungeon Editing (Label-Aware):

   • "Add 3 soldiers to the Eastern Palace entrance room"
   • "Place a chest in the Hyrule Castle treasure room"

3. Tile16 Reference (Inline for AI):

   • Grass: 0x020, Dirt: 0x022, Tree: 0x02E
   • Water edges: 0x14C (top), 0x14D (middle), 0x14E (bottom)
   • Bush: 0x003, Rock: 0x004, Flower: 0x021, Sand: 0x023

Note: AI can support additional edit types (sprites, palettes, patches) but tile16 is the primary validated use case.

4. Service Selection Logic ✅

AI Service Factory (CreateAIService())

Selection Priority:

1. If GEMINI_API_KEY set → Use Gemini
2. If Ollama available → Use Ollama
3. Fallback → MockAIService

Configuration:

# Use Gemini (requires API key)
export GEMINI_API_KEY="your-key-here"
./z3ed agent plan --prompt "Make soldiers red"

# Use Ollama (requires ollama serve running)
unset GEMINI_API_KEY
ollama serve  # Terminal 1
./z3ed agent plan --prompt "Make soldiers red"  # Terminal 2

# Use Mock (always works, no dependencies)
# Automatic fallback if neither Gemini nor Ollama available

📋 What's Ready to Test

Test Scenario 1: Ollama Local LLM

Prerequisites:

# Install Ollama
brew install ollama  # macOS
# or download from https://ollama.com

# Pull recommended model
ollama pull qwen2.5-coder:7b

# Start Ollama server
ollama serve

Test Commands:

cd /Users/scawful/Code/yaze
export ROM_PATH="assets/zelda3.sfc"

# Test 1: Simple palette change
./build-grpc-test/bin/z3ed agent plan \
  --prompt "Change palette 0 color 5 to red"

# Test 2: Complex sprite modification
./build-grpc-test/bin/z3ed agent plan \
  --prompt "Make all soldier armors blue"

# Test 3: Overworld editing
./build-grpc-test/bin/z3ed agent plan \
  --prompt "Place a tree at position 10, 20 on map 0"

# Test 4: End-to-end with sandbox
./build-grpc-test/bin/z3ed agent run \
  --prompt "Validate the ROM" \
  --rom assets/zelda3.sfc \
  --sandbox

Test Scenario 2: Gemini API

Prerequisites:

# Get API key from https://aistudio.google.com/apikey
export GEMINI_API_KEY="your-actual-api-key-here"

Test Commands:

# Same commands as Ollama scenario above
# Service selection will automatically use Gemini when key is set

# Verify Gemini is being used
./build-grpc-test/bin/z3ed agent plan --prompt "test" 2>&1 | grep -i "gemini\|model"

Test Scenario 3: Fallback to Mock

Test Commands:

# Ensure neither Gemini nor Ollama are available
unset GEMINI_API_KEY
# (Stop ollama serve if running)

# Should fall back to Mock and return hardcoded test commands
./build-grpc-test/bin/z3ed agent plan --prompt "anything"
