## 🔧 How It Works

### Example: "Open Overworld editor"

**Step 1: Parse Prompt**
```cpp
TestWorkflowGenerator generator;
auto workflow = generator.GenerateWorkflow("Open Overworld editor");
// Result:
// - Click(button:Overworld)
// - Wait(window_visible:Overworld Editor, 5000ms)
```

**Step 2: Execute Workflow**
```cpp
GuiAutomationClient client("localhost:50052");
client.Connect();

// Execute each step
auto result1 = client.Click("button:Overworld");  // 125ms
auto result2 = client.Wait("window_visible:Overworld Editor");  // 1250ms
// Total: 1375ms
```

**Step 3: Report Results**
```
[1/2] Click(button:Overworld) ... ✓ (125ms)
[2/2] Wait(window_visible:Overworld Editor, 5000ms) ... ✓ (1250ms)

✅ Test passed in 1375ms
```

## 🚀 How to Use

### Build with gRPC Support

```bash
# Configure
cmake -B build-grpc-test -DYAZE_WITH_GRPC=ON

# Build
cmake --build build-grpc-test --target yaze -j$(sysctl -n hw.ncpu)
cmake --build build-grpc-test --target z3ed -j$(sysctl -n hw.ncpu)
```

### Run Automated GUI Tests

```bash
# Terminal 1: Start YAZE with test harness
./build-grpc-test/bin/yaze.app/Contents/MacOS/yaze \
  --enable_test_harness \
  --test_harness_port=50052 \
  --rom_file=assets/zelda3.sfc &

# Terminal 2: Run test command
./build-grpc-test/bin/z3ed agent test \
  --prompt "Open Overworld editor"
```

### Supported Prompts

1. **Open Editor**
   ```bash
   z3ed agent test --prompt "Open Overworld editor"
   ```

2. **Open and Verify**
   ```bash
   z3ed agent test --prompt "Open Dungeon editor and verify it loads"
   ```

3. **Click Button**
   ```bash
   z3ed agent test --prompt "Click Open ROM button"
   ```

4. **Type Input**
   ```bash
   z3ed agent test --prompt "Type 'zelda3.sfc' in filename input"
   ```

## 📊 Current Status

### ✅ Complete
- **IT-01**: ImGuiTestHarness gRPC service (11 hours)
- **IT-02**: CLI agent test command (4 hours) ← **Today's Work**
- **AW-01/02/03**: Proposal infrastructure + GUI
- **Phase 6**: Resource catalog

### 📋 Next (Priority 1)
- **E2E Validation**: Test all systems together (2-3 hours)
- Follow `E2E_VALIDATION_GUIDE.md` checklist
- Validate 4 phases:
  1. Automated test script
  2. Manual proposal workflow
  3. Real widget automation
  4. Documentation updates

### 🔮 Future (Priority 3)
- **AW-04**: Policy evaluation framework (6-8 hours)
- YAML-based constraints for proposal acceptance
- Integration with ProposalDrawer UI

## 🎓 Key Design Decisions

### 1. Why gRPC Client Wrapper?

**Problem**: CLI needs to automate GUI without duplicating logic  
**Solution**: Thin wrapper around gRPC service  
**Benefits**:
- Reuses existing test harness infrastructure
- Type-safe C++ API
- Proper error handling with absl::Status
- Easy to extend

### 2. Why Natural Language Parsing?

**Problem**: Users want high-level commands, not low-level RPC calls  
**Solution**: Pattern matching with regex  
**Benefits**:
- Intuitive user interface
- Extensible pattern system
- Helpful error messages
- Easy to add new patterns

### 3. Why Separate TestWorkflow struct?

**Problem**: Need to plan before executing  
**Solution**: Generate workflow, then execute  
**Benefits**:
- Can show plan before running
- Enable dry-run mode
- Better error messages
- Easier testing

## 📈 Metrics

### Code Quality
- **New Lines**: ~1,350 (660 implementation + 690 documentation)
- **Files Created**: 7 (4 source + 1 build + 2 docs)
- **Files Modified**: 2 (agent.cc + CMakeLists.txt)
- **Test Coverage**: E2E test script + validation guide

### Time Investment
- **Design**: 1 hour (architecture + interfaces)
- **Implementation**: 2 hours (coding + debugging)
- **Documentation**: 1 hour (guides + comments)
- **Total**: 4 hours

### Functionality
- **RPC Methods**: 6 wrapped (Ping, Click, Type, Wait, Assert, Screenshot)
- **Pattern Types**: 4 supported (Open, OpenVerify, Type, Click)
- **Command Flags**: 4 supported (prompt, host, port, timeout)

## 🐛 Known Limitations

### Natural Language Parser
- Limited to 4 pattern types (easily extensible)
- Case-sensitive widget names (intentional for precision)
- No multi-step conditionals (future enhancement)

### Widget Discovery
- Requires exact label matches
- No fuzzy matching (could add)
- No widget introspection (limitation of ImGui)

### Error Handling
- Basic error messages (could be more descriptive)
- No suggestions on typos (could add Levenshtein distance)
- No recovery from failed steps (could add retry logic)

### Platform Support
- gRPC test harness: macOS/Linux only
- Windows: Manual testing required
- Conditional compilation: YAZE_WITH_GRPC required

3. **Comprehensive Docs**: E2E guide will save hours of debugging
4. **Code Reuse**: Leveraged existing IT-01 infrastructure

### What Could Be Improved
1. **More Pattern Types**: Only 4 patterns, could add more
2. **Better Error Messages**: Could include suggestions
3. **Widget Discovery**: No introspection, must know exact names
4. **Cross-Platform**: Windows support missing

### Future Considerations
1. **LLM Integration**: Generate patterns from examples
