# z3ed Implementation Progress - October 2, 2025

**Date**: October 2, 2025  
**Status**: Priority 2 Implementation Complete ✅  
**Next Action**: Execute E2E Validation (Priority 1)

## Summary

Today's work completed the **Priority 2: CLI Agent Test Command (IT-02)** implementation, which enables natural language-driven GUI automation. This was implemented alongside preparing comprehensive validation procedures for Priority 1.

## What Was Implemented

### 1. GuiAutomationClient (gRPC Wrapper) ✅

**Files Created**:
- `src/cli/service/gui_automation_client.h`
- `src/cli/service/gui_automation_client.cc`

**Features**:
- Full gRPC client for ImGuiTestHarness service
- Wrapped all 6 RPC methods (Ping, Click, Type, Wait, Assert, Screenshot)
- Type-safe C++ API with proper error handling
- Connection management with health checks
- Conditional compilation for YAZE_WITH_GRPC

**Example Usage**:
```cpp
GuiAutomationClient client("localhost:50052");
RETURN_IF_ERROR(client.Connect());

auto result = client.Click("button:Overworld", ClickType::kLeft);
if (!result.ok()) return result.status();

std::cout << "Clicked in " << result->execution_time.count() << "ms\n";
```

### 2. TestWorkflowGenerator (Natural Language Parser) ✅

**Files Created**:
- `src/cli/service/test_workflow_generator.h`
- `src/cli/service/test_workflow_generator.cc`

**Features**:
- Pattern matching for common GUI test scenarios
- Converts natural language to structured test steps
- Extensible pattern system for new prompt types
- Helpful error messages with suggestions

**Supported Patterns**:
1. **Open Editor**: "Open Overworld editor"
   - Click button → Wait for window
2. **Open and Verify**: "Open Dungeon editor and verify it loads"
   - Click button → Wait for window → Assert visible
3. **Type Input**: "Type 'zelda3.sfc' in filename input"
   - Click input → Type text with clear_first
4. **Click Button**: "Click Open ROM button"
   - Single click action

**Example Usage**:
```cpp
TestWorkflowGenerator generator;
auto workflow = generator.GenerateWorkflow("Open Overworld editor");

// Returns:
// Workflow: Open Overworld Editor
//   1. Click(button:Overworld)
//   2. Wait(window_visible:Overworld Editor, 5000ms)
```

### 3. Enhanced Agent Handler ✅

**Files Modified**:
- `src/cli/handlers/agent.cc` (added includes, replaced HandleTestCommand)

**New Implementation**:
- Parses `--prompt`, `--host`, `--port`, `--timeout` flags
- Generates workflow from natural language prompt
- Connects to test harness via GuiAutomationClient
- Executes workflow with progress indicators
- Displays timing and success/failure for each step
- Returns structured error messages

**Command Interface**:
```bash
z3ed agent test --prompt "..." [--host localhost] [--port 50052] [--timeout 30]
```

**Example Output**:
```
=== GUI Automation Test ===
Prompt: Open Overworld editor
Server: localhost:50052

Generated workflow:
Workflow: Open Overworld Editor
  1. Click(button:Overworld)
  2. Wait(window_visible:Overworld Editor, 5000ms)

✓ Connected to test harness

[1/2] Click(button:Overworld) ... ✓ (125ms)
[2/2] Wait(window_visible:Overworld Editor, 5000ms) ... ✓ (1250ms)

✅ Test passed in 1375ms
```

### 4. Build System Integration ✅

**Files Modified**:
- `src/CMakeLists.txt` (added new source files to yaze_core)

**Changes**:
```cmake
# CLI service sources (needed for ProposalDrawer)
cli/service/proposal_registry.cc
cli/service/rom_sandbox_manager.cc
cli/service/gui_automation_client.cc      # NEW
cli/service/test_workflow_generator.cc    # NEW
```

### 5. Comprehensive E2E Validation Guide ✅

**Files Created**:
- `docs/z3ed/E2E_VALIDATION_GUIDE.md`

**Contents**:
- 4-phase validation checklist (3 hours estimated)
- Phase 1: Automated test script validation (30 min)
- Phase 2: Manual proposal workflow testing (60 min)
- Phase 3: Real widget automation testing (60 min)
- Phase 4: Documentation updates (30 min)
- Success criteria and known limitations
- Troubleshooting and issue reporting procedures

## Build Instructions

### Build z3ed with gRPC Support

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

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

# Verify builds
ls -lh build-grpc-test/bin/yaze.app/Contents/MacOS/yaze
ls -lh build-grpc-test/bin/z3ed
```

### Quick Test

```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 automated test
./build-grpc-test/bin/z3ed agent test \
  --prompt "Open Overworld editor"

# Expected: Test passes in ~1-2 seconds
```

## Known Limitations

1. **Natural Language Parsing**: Limited to 4 pattern types (extensible)
2. **Widget Discovery**: Requires exact widget names (case-sensitive)
3. **Error Messages**: Could be more descriptive (improvements planned)
4. **Screenshot**: Not yet implemented (returns stub)
5. **Windows**: gRPC test harness not supported (Unix-like only)

---

## Future Enhancements

### Short Term (Next 2 weeks)
1. **Policy Evaluation Framework (AW-04)**: YAML-based constraints
2. **Enhanced Prompt Parsing**: More pattern types
3. **Better Error Messages**: Include suggestions and examples
4. **Screenshot Implementation**: Actual image capture

### Medium Term (Next month)
1. **Real LLM Integration**: Replace MockAIService with Gemini
2. **Workflow Recording**: Learn from user actions
3. **Test Suite Management**: Save/load test workflows
4. **CI Integration**: Automated GUI testing in pipeline

### Long Term (2-3 months)
1. **Multi-Step Workflows**: Complex scenarios with branching
2. **Visual Regression Testing**: Compare screenshots
3. **Performance Profiling**: Identify slow operations
4. **Cross-Platform**: Windows support for test harness
