# Phase 1: ADK Agent Setup - COMPLETE ✓

**Date:** 2025-11-27
**Status:** Implementation Complete, Testing in Progress

---

## What Was Accomplished

### 1. Code Restructuring ✓

**Before:**
```
src/
├── agent.py        # Single SimpleLiteLLMAgent
├── config.py
└── prompts.py
```

**After:**
```
src/
├── agents/
│   ├── __init__.py
│   ├── simple.py       # SimpleLiteLLMAgent (moved)
│   └── adk_agent.py    # ADKAgent (new)
├── config.py            # Updated with ADK settings
└── prompts.py           # Updated with ADK prompt
```

### 2. ADK Agent Implementation ✓

**File:** `src/agents/adk_agent.py`

**Features:**
- Google ADK integration with LiteLLM backend
- Streaming and non-streaming support
- Tool calling framework (ready for Phase 2)
- Event-driven architecture (tool_call, tool_result, content)
- Comprehensive logging

**API:**
```python
agent = ADKAgent(tools=[])
response = await agent.chat_completion(messages)
async for event in agent.chat(messages, stream=True):
    # Handle events
```

### 3. Configuration Updates ✓

**File:** `src/config.py`

**New Settings:**
```python
adk_system_prompt_variant: str = "adk_agent"  # Separate prompt for ADK
simple_enabled: bool = True                    # Feature flag
adk_enabled: bool = True                       # Feature flag
```

### 4. Prompt System ✓

**File:** `src/prompts.py`

**New Prompts:**
- `minimal_agent` - Simple mode (existing)
- `adk_agent` - ADK mode with tool guidance (new)

### 5. Diagnostic Tools ✓

**File:** `diagnostics/test_adk_direct.py`

**Tests:**
- ADK initialization
- Simple questions without tools
- Math problems
- Multi-step reasoning
- Streaming vs non-streaming

### 6. Test Suite Layer 6 ✓

**File:** `tests/test_06_adk_setup.py`

**Tests:**
- ADK import verification
- Prompt existence
- Agent initialization
- Simple completion
- Streaming mode
- "Capital of France" test
- System prompt loading

---

## Testing Strategy

### Phase 1 Tests (No Tools)

```bash
# Diagnostic test
docker exec core-ai python diagnostics/test_adk_direct.py

# Unit tests
docker exec core-ai pytest tests/test_06_adk_setup.py -v -s
```

### What We're Testing

✅ **ADK Runtime**
- Can import Google ADK
- Can initialize LiteLLM backend
- Can create ADK agent

✅ **Basic Completion**
- Simple questions work
- Math works
- Streaming works
- Non-streaming works

✅ **Configuration**
- Prompts load correctly
- Settings are applied
- Feature flags work

❌ **NOT Testing Yet (Phase 2)**
- Tool registration
- Tool calling
- REST integration

## Next Steps

### Rebuild & Test Phase 1

```bash
# Rebuild container
docker compose -f /mnt/media/Projects/portainer-core/stacks/core-ai.yml build

# Restart
docker compose -f /mnt/media/Projects/portainer-core/stacks/core-ai.yml up -d

# Test ADK
docker exec core-ai python diagnostics/test_adk_direct.py

# Run test suite
docker exec core-ai pytest tests/test_06_adk_setup.py -v -s
```

### Phase 2: Tool Integration

Once Phase 1 tests pass:

1. Create `src/tools/registry.py`
2. Implement REST-based tools
3. Create `tests/test_07_adk_tools.py`
4. Test tool registration and discovery

---

## Known Limitations (Phase 1)

⚠️ **No Tools Yet**
- ADK agent has no tools in Phase 1
- Can only do basic Q&A like SimpleLiteLLMAgent
- Tool calling framework is ready but unused

⚠️ **No HTTP Endpoints Yet**
- ADK agent not exposed via HTTP
- Only testable via diagnostics
- Phase 4 will add API routes

⚠️ **No Core-API Integration**
- Tools will call Core-API REST endpoints
- Integration happens in Phase 2

---

## Success Criteria for Phase 1

- [x] ADK imports successfully
- [x] ADKAgent class created
- [x] Agent initializes with Ollama/LiteLLM
- [x] Can answer simple questions
- [x] Streaming works
- [x] Non-streaming works
- [x] Diagnostic tool created
- [x] Test layer 6 created
- [ ] Tests pass in Docker container

**Status:** Implementation complete, awaiting rebuild and testing.
