## Phase 1: Real LLM Integration - PydanticAI + Tools

**Goal**: Connect to actual language models and establish the base plumbing

**Note**: Ollama is an external service dependency (already running separately)

### Deliverables

1. **PydanticAI Integration** ✅
   - PydanticAI → Ollama connection ✅
   - Agent creation patterns ✅
   - Streaming response handling ✅
   - Error handling and retries ✅

2. **Convert Tatlock Agent** ✅
   - Convert Tatlock agent from mock to PydanticAI ✅
   - British butler personality prompt ✅
   - Research-oriented mindset ✅
   - Streaming to reasoning output ✅
   - Tool calling framework setup ✅

3. **Permanent Tools** ✅
   - Calculator: Safe mathematical expression evaluation ✅
   - Date/Time toolkit: Current time, relative dates, time differences ✅
   - Web search: SearXNG integration (external service) ✅
   - Tool registration with PydanticAI ✅

4. **Testing Infrastructure** ✅
   - Integration tests with real LLM ✅
   - Tool functionality tests ✅
   - Response quality validation ✅
   - 131 tests, 81.78% coverage ✅

### Success Criteria
- [x] **PydanticAI agents can call Ollama** (mistral-nemo:latest)
- [x] **Streaming works end-to-end**
- [x] **Tool calling framework functional**
- [x] **Permanent tools working** (calculator, date/time, search)
- [x] **Tests pass with real LLM**
- [ ] Can switch models dynamically (e.g., Codestral for code)

### Status
**✅ MOSTLY COMPLETE** - Tatlock agent functional with permanent tools

### Remaining Work
- Dynamic model switching for specialized tasks (e.g., Codestral for coding)

### Why First?
Without real LLM integration, we can't meaningfully implement the Steward/Butler pattern. Everything else depends on having actual AI agents working.

---

## Phase 2: Orchestration Layer - The Steward

**Goal**: Implement the first-tier LLM call for tool/agent selection

**Purpose**: The Steward performs crucial preparatory work before Tatlock engages with a request. By analyzing incoming requests and determining which tools, services, and household staff members will be needed, the Steward creates a curated recommendation that streamlines Tatlock's work and prevents cognitive overload.

### Core Architecture

The Steward operates as the first tier in the two-tier request flow:

```
User Request → Orchestrator → Steward Analysis → Recommendations → Tatlock (with scoped tools/agents)
```

**Key Principle**: The Steward narrows the scope to only relevant capabilities, making Tatlock's decision-making cleaner and more focused.

### Deliverables

#### 1. Tool & Agent Registry System

**Purpose**: Centralized catalog of all available capabilities for the Steward to recommend

**Implementation Details**:
- **Registry Module** (`src/core/registry.py`)
  - Tool registration decorator pattern
  - Agent registration with capability metadata
  - Category-based organization (computation, information, automation, communication)
  - Dynamic tool/agent discovery and loading

- **Tool Metadata Schema**
  ```python
  {
    "name": "calculator",
    "category": "computation",
    "description": "Safe mathematical expression evaluation",
    "capabilities": ["arithmetic", "algebra", "trigonometry"],
    "cost": "low",  # computational cost indicator
    "requires_network": false
  }
  ```

- **Agent Metadata Schema**
  ```python
  {
    "name": "developer",
    "role": "The Developer",
    "category": "technical",
    "description": "Software development assistance",
    "domains": ["code_generation", "debugging", "architecture"],
    "specialized_model": "codestral",  # optional
    "cost": "high"
  }
  ```

- **Registry API**
  - `get_all_tools()` - List all available tools
  - `get_all_agents()` - List all expert agents
  - `get_by_category(category)` - Filter by category
  - `search_by_capability(query)` - Semantic search (future: vector search)

**Testing**:
- Unit tests for registration and retrieval
- Test dynamic loading of new tools/agents
- Validate metadata schemas

#### 2. Steward PydanticAI Agent

**Purpose**: First-tier LLM that analyzes requests and recommends relevant tools/agents

**Implementation Details**:

- **Agent Module** (`src/agents/steward.py`)
  ```python
  from pydantic_ai import Agent, RunContext
  from pydantic import BaseModel

  class StewardRecommendation(BaseModel):
      """Structured output from Steward analysis"""
      recommended_tools: list[str]
      recommended_agents: list[str]
      reasoning: str
      estimated_complexity: str  # "simple", "moderate", "complex"
      requires_multi_step: bool

  steward = Agent(
      'ollama:mistral-nemo',  # Same base model as Tatlock
      result_type=StewardRecommendation,
      system_prompt="""..."""
  )
  ```

- **System Prompt Engineering**
  - Role: Estate steward responsible for efficient household coordination
  - Task: Analyze requests to determine needed resources
  - Output: Structured recommendations with reasoning
  - Constraints: Be conservative (recommend only truly relevant capabilities)
  - Context: Full registry of available tools and agents

- **Steward Tools**
  ```python
  @steward.tool
  def get_available_capabilities(ctx: RunContext) -> dict:
      """Get catalog of all available tools and agents."""
      return {
          "tools": registry.get_all_tools(),
          "agents": registry.get_all_agents()
      }
  ```

- **Request Analysis Flow**
  1. Receive user request
  2. Query capability registry via tool
  3. Analyze request for required capabilities
  4. Generate structured recommendation
  5. Format as note to Tatlock

**Testing**:
- Test various request types (simple, complex, multi-domain)
- Verify recommendations are relevant and not over-inclusive
- Test structured output parsing
- Validate reasoning quality

#### 3. Request Preprocessing Pipeline

**Purpose**: Integration layer that routes requests through Steward before Tatlock

**Implementation Details**:

- **Preprocessing Module** (`src/core/preprocessing.py`)
  ```python
  async def preprocess_request(user_request: str) -> EnrichedRequest:
      """
      1. Call Steward for analysis
      2. Get recommendations
      3. Enrich original request
      4. Return scoped context for Tatlock
      """
      # Get Steward analysis
      steward_result = await steward.run(user_request)
      recommendations = steward_result.data

      # Create note to Tatlock
      steward_note = format_steward_note(recommendations)

      # Build scoped tool/agent list
      scoped_tools = get_scoped_tools(recommendations.recommended_tools)
      scoped_agents = get_scoped_agents(recommendations.recommended_agents)

      return EnrichedRequest(
          original_request=user_request,
          steward_note=steward_note,
          available_tools=scoped_tools,
          available_agents=scoped_agents,
          metadata=recommendations
      )
  ```

- **Note Formatting**
  ```
  === Internal Note from the Steward ===

  Request Analysis:
  {steward reasoning}

  Recommended Tools:
  - calculator: For mathematical computations
  - web_search: To find current information

  Recommended Household Staff:
  - The Developer: For code generation assistance

  Estimated Complexity: moderate
  ===================================

  [Original User Request]
  ```

- **Orchestrator Integration**
  - Modify `src/responses/service.py` to call preprocessing
  - Prepend Steward note to request before sending to Tatlock
  - Limit Tatlock's tool access to recommended tools only
  - Stream Steward's reasoning to output

**Testing**:
- Integration tests for full preprocessing flow
- Test request enrichment format
- Verify tool scoping works correctly
- Test streaming of Steward reasoning

#### 4. Real-Time Transparency

**Purpose**: Stream Steward's analysis to user's reasoning output

**Implementation Details**:

- **Streaming Integration** (`src/responses/streaming.py`)
  - Add Steward analysis phase to stream
  - Format as reasoning item
  - Include recommendation summary

- **Example Output to User**:
  ```
  [Reasoning]
  Consulting the Steward for resource planning...

  The Steward's Analysis:
  - Request requires mathematical computation
  - Need to verify current information via web search
  - May benefit from Developer's code expertise

  Recommended: calculator, web_search, The Developer

  Proceeding with scoped resources...
  ```

**Testing**:
- Test streaming of Steward analysis
- Verify formatting in Open WebUI
- Test error handling if Steward fails

#### 5. Model Efficiency Optimization

**Purpose**: Ensure the base model stays loaded in VRAM

**Implementation Details**:

- **Shared Model Configuration**
  - Both Steward and Tatlock use `ollama:mistral-nemo` by default
  - Sequential calls (Steward → Tatlock) keep model hot
  - No reload delays between tiers

- **Performance Monitoring**
  - Log response times for Steward calls
  - Track total request latency (Steward + Tatlock)
  - Identify optimization opportunities

**Testing**:
- Benchmark Steward → Tatlock call latency
- Verify model stays loaded between calls
- Test performance under load

### Implementation Strategy

#### Week 1-2: Foundation
- [ ] Design and implement registry system
- [ ] Create tool/agent metadata schemas
- [ ] Build registry API with tests
- [ ] Migrate existing tools to registry

#### Week 3-4: Steward Agent
- [ ] Create Steward PydanticAI agent
- [ ] Engineer system prompt for analysis
- [ ] Implement structured recommendation output
- [ ] Add registry query tool
- [ ] Test with various request types

#### Week 5-6: Integration
- [ ] Build request preprocessing pipeline
- [ ] Implement note formatting
- [ ] Integrate with Orchestrator
- [ ] Add streaming transparency
- [ ] Tool scoping for Tatlock

#### Week 7: Testing & Refinement
- [ ] End-to-end integration tests
- [ ] Performance optimization
- [ ] Prompt refinement based on results
- [ ] Documentation and examples

### Success Criteria

- [x] **Steward analyzes incoming requests** using PydanticAI agent
- [x] **Produces structured recommendations** (tools, agents, reasoning)
- [x] **Recommendations formatted as prepended note** to Tatlock
- [x] **Tool registry is queryable and extensible** via clean API
- [x] **Steward output visible in reasoning stream** for transparency
- [x] **Only recommended tools available** to Tatlock (scoped context)
- [x] **Base model stays loaded** between Steward and Tatlock calls
- [x] **Recommendations are accurate** (not over/under-inclusive)
- [x] **Integration tests pass** for full Steward → Tatlock flow

### Status
**✅ COMPLETE** (v0.2.5)

### Performance Targets

- **Steward Analysis Time**: < 2 seconds for typical requests
- **Total Added Latency**: < 3 seconds including streaming
- **Recommendation Accuracy**: > 90% relevance (manual evaluation)
- **Model Reload Delay**: 0 seconds (model stays hot)

### Risk Mitigation

**Risk**: Steward recommendations too broad (defeats purpose)
- Mitigation: Conservative prompt engineering, test with diverse requests, iterate

**Risk**: Added latency unacceptable to users
- Mitigation: Stream Steward reasoning for transparency, optimize prompt, parallel processing where possible

**Risk**: Tool registry becomes unwieldy
- Mitigation: Good categorization, semantic search (future), regular pruning

**Risk**: Steward and Tatlock models compete for VRAM
- Mitigation: Use same base model, sequential calls, monitor memory

### Future Enhancements (Post-Phase 2)

- **Semantic Search**: Vector-based capability search instead of metadata lookup
- **Learning from Usage**: Track which recommendations work well, adjust over time
- **Confidence Scores**: Steward provides confidence for each recommendation
- **Request Classification**: Cache classifications for similar requests
- **Multi-Model Support**: Allow Steward to recommend specialized models for specific tasks

### Estimated Effort

**7-8 weeks** - Core intelligence routing with comprehensive implementation

### Why Second?

The Steward is the foundation of the household architecture. Without it, we'd need to expose all tools/agents to Tatlock, creating cognitive overload and poor decision-making. The Steward enables the focused expertise pattern that makes the whole system work.

## Dependencies Between Phases

```
Phase 1 (Ollama + PydanticAI) ← Foundation for all AI
    ↓
Phase 2 (Steward)
    ↓
Phase 3 (Butler/Tatlock)
    ↓
Phase 4 (Expert Agents) ← Phase 7 (MCP) can enhance
    ↓
Phase 5 (Database/Multi-Tenancy) ← Can be deferred
    ↓
Phase 6 (Extended Services) → Phase 8 (Advanced Memory)
    ↓
Phase 9 (Extended Staff) → Phase 10 (UX) → Phase 11 (Production)
```

**Critical Path**: Phases 1 → 2 → 3 → 4 must be sequential
**Can Be Deferred**: Phase 5 (Database) until you need persistence
**Parallel Opportunities**: Phase 6 and 7 can overlap; Phase 9 and 10 ongoing
