# 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
  ```bash
  $ ls -lh build-grpc-test/bin/z3ed
  -rwxr-xr-x  69M Oct  3 02:18 build-grpc-test/bin/z3ed
  ```

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

**Test Commands**:
```bash
# 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**:
```bash
# 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"
```
