-## Project Overview
+> **📖 Important**: Before working on this project, read [PHILOSOPHY.md](PHILOSOPHY.md) to understand the system vision, architectural patterns, and design goals. All development should work towards realizing those patterns.
+# AGENTS.md
 
-This project implements an OpenAI-compatible API endpoint using FastAPI, with streaming support. Currently returns mock responses - infrastructure prepared for future Ollama/PydanticAI integration.
+> **Start every session by reading this file.**
+> This file outlines the operational protocols, coding standards, and architectural decisions for this FastAPI project.
 
-**Current State**: Production-ready testing API with Responses API and Open WebUI integration
-**Future Integration**: PydanticAI for real LLM agents (tatlock model placeholder ready)
+## 1. Agent Operational Protocols
 
-### Current Architecture (As of 2025-12-06)
+### 🧠 Work Patterns (Plan-Act-Reflect)
+* **Plan:** Before writing code, briefly outline your plan. Identify which files you will touch and what the side effects might be.
+* **Act:** Execute the changes in small, atomic steps.
+* **Reflect:** After coding, verify your work. Did you break existing tests? Did you add new tests?
 
-This project implements a **hybrid architecture** with the Responses API as the primary endpoint and Chat Completions as a compatibility wrapper:
+### 🌐 Internal Service Access
+* **git.schweitz.net**: Access via `http://localhost:3002` (direct Gitea) to bypass Authentik SSO
+  * Example: `curl http://localhost:3002/jpmschweitzer/library-desk/raw/branch/main/README.md`
+  * Public repos are readable without authentication
+  * Related repos: `library-desk`, `scheduler`
 
-```
-Client (Open WebUI)
-      ↓
-Chat Completions (/v1/chat/completions) → Wrapper
-      ↓
-Responses API (/v1/responses) → Primary
-      ↓
-Agent Interface (lorem-tester, tatlock)
-```
+### 🛡️ Git Discipline
+* **NEVER commit to `main` or `master` directly.** Always create a feature branch: `feature/your-feature-name` or `fix/issue-description`.
+* **Commit Messages:** Use the [Conventional Commits](https://www.conventionalcommits.org/) format.
+    * `feat: add user login endpoint`
+    * `fix: resolve database connection timeout`
+    * `refactor: split monolith dependency file`
+* **Atomic Commits:** Keep commits small. One logical change = one commit.
 
-**Key Architectural Decisions:**
+### 📝 Changelog Maintenance
+* **Update `CHANGELOG.md`** with every user-facing change.
+* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
 
-1. **Single Source of Truth**: All response generation happens in the Responses API
-   - Structured output with reasoning, function_call, and message items
-   - Real-time stop sequence and max tokens enforcement
-   - Conversation history tracking
-   - Context window management
+---
 
-2. **Chat Completions Wrapper**: Provides compatibility without duplicating logic
-   - Calls Responses API internally
-   - Automatically enables reasoning generation
-   - Converts reasoning items to `<think>` tags for Open WebUI
-   - Maintains OpenAI-compatible format
+## 2. FastAPI Architecture & Best Practices
+*Reference: [FastAPI Best Practices](https://github.com/zhanymkanov/fastapi-best-practices)*
 
-3. **Agent Interface**: Clean abstraction for multiple models
-   - **lorem-tester**: Full-featured mock agent with realistic behavior
-     - Reasoning summaries (adjustable effort levels)
-     - Random tool/function calls
-     - Error triggers for testing
-     - Temperature variation
-   - **tatlock**: Placeholder for future PydanticAI agent
+### 📂 Project Structure (Directory-based, NOT File-type based)
+Do **not** group files by type (e.g., one huge `routers` folder). Group by **domain/module** inside a `src/` directory.
 
-4. **Hybrid Conversation History**:
-   - Client MUST send full context in `input` array (OpenAI compatible)
-   - Server optionally tracks via `metadata.conversation_id`
-   - Auto-generates deterministic IDs from first message
-   - Supports future vector memory integration (Qdrant)
-
-**Why This Architecture?**
-
-- **Open WebUI Compatibility**: Native Responses API support not yet in stable release
-- **Future-Proof**: Easy migration when Open WebUI adds native support
-- **Testability**: Full-featured mock agent (lorem-tester) for integration testing
-- **Clean Separation**: Responses API as stable core, wrappers can change
-

-
-**Key Architectural Principles**:
-- **Single Source of Truth**: Responses API handles all generation logic
-- **Wrapper Pattern**: Chat Completions wraps Responses API without duplicating code
-- **Agent Abstraction**: AgentInterface defines contract for all models
-- **Domain Separation**: Each domain has its own router, schemas, service
-- **Service Layer**: Business logic in services, not routers
-- **Type Safety**: Pydantic models for ALL request/response validation
-- **Async First**: All I/O operations use async/await
-
-### Async/Await Best Practices
-
-**Critical Understanding**: FastAPI handles sync and async routes differently:
-
-- **Async routes** (`async def`): Called directly in event loop
-  - Use ONLY for non-blocking operations
-  - Perfect for `await httpx.get()`, database queries, file I/O
-  - **NEVER** use blocking calls like `time.sleep()` - this blocks entire server
-
-- **Sync routes** (`def`): Run in thread pool
-  - Use for CPU-intensive work or blocking SDKs
-  - Blocking I/O won't freeze the event loop
-  - Example: `time.sleep(10)` is safe here
-
-**Example**:
-```python
-@router.get("/terrible")
-async def terrible():
-    time.sleep(10)  # ❌ BLOCKS ENTIRE SERVER
-
-@router.get("/good")
-def good():
-    time.sleep(10)  # ✅ Runs in thread pool
-
-@router.get("/perfect")
-async def perfect():
-    await asyncio.sleep(10)  # ✅ Non-blocking async
-```
-
-**For CPU-intensive tasks**: Use separate worker processes (not threads) due to Python's GIL.
-
-### Pydantic Configuration
-
-**Custom Base Model**: All schemas inherit from `CustomBaseModel` for consistent behavior:
-
-```python
-# src/core/models.py
-class CustomBaseModel(BaseModel):
-    model_config = ConfigDict(
-        json_encoders={datetime: datetime_to_iso_str},
-        populate_by_name=True,
-        use_enum_values=True,
-        validate_assignment=True,
-    )
-
-    def serializable_dict(self, **kwargs):
-        """Return dict with only JSON-serializable fields."""
-        return jsonable_encoder(self.model_dump(**kwargs))
-```
-
-**Benefits**:
-- Consistent datetime serialization across all responses
-- Alias support for field name flexibility
-- Easy JSON encoding for logging/debugging
-
-**Decoupled Settings**: Split configuration by domain instead of one monolithic file:
-
-```python
-# src/core/config.py - Global settings
-class Config(BaseSettings):
-    DATABASE_URL: PostgresDsn
-    ENVIRONMENT: Environment
-
-# src/chat/config.py - Chat-specific settings
-class ChatConfig(BaseSettings):
-    MAX_TOKENS: int
-    DEFAULT_TEMPERATURE: float
-```
-
-### Dependency Injection Patterns
-
-**Validation with Dependencies**: Use dependencies for complex validations:
-
-```python
-async def valid_post_id(post_id: UUID4) -> dict:
-    """Validate post exists in database."""
-    post = await service.get_by_id(post_id)
-    if not post:
-        raise PostNotFound()
-    return post
-
-@router.get("/posts/{post_id}")
-async def get_post(post: dict = Depends(valid_post_id)):
-    return post  # Already validated!
-```
-
-**Chaining Dependencies**: Build reusable validation layers:
-
-```python
-async def valid_owned_post(
-    post: dict = Depends(valid_post_id),
-    token_data: dict = Depends(parse_jwt_data),
-) -> dict:
-    if post["creator_id"] != token_data["user_id"]:
-        raise UserNotOwner()
-    return post
-```
-
-**Dependency Caching**: Dependencies are cached within request scope - FastAPI only executes each dependency once per request, even if used multiple times.
-
-### Application Factory Pattern
-
-Main.py uses factory pattern for testability and configuration:
-
-```python
-def create_application() -> FastAPI:
-    """Create and configure FastAPI app."""
-    app = FastAPI(title=config.APP_NAME)
-
-    # Add middleware
-    app.add_middleware(CORSMiddleware, ...)
-
-    # Register exception handlers
-    register_exception_handlers(app)
-
-    # Include routers
-    app.include_router(chat_router, prefix="/v1")
-
-    return app
-
-app = create_application()
-```
-
-## Development Guidelines
-
-### Code Structure (Current Implementation)
-- ✅ Use async/await for ALL I/O operations (database, HTTP, file access)
-- ✅ Use sync (def) for blocking SDKs or CPU-intensive work
-- ✅ Implement proper error handling and logging
-- ✅ Follow dependency injection for validation and shared resources
-- ✅ Use Pydantic models for ALL request/response validation
-- ✅ Keep business logic in service modules, not routers
-- ✅ Domain-based project structure (not file-type based)
-
-### Security Considerations
-- ✅ Validate all inputs using Pydantic models
-- ✅ Use environment variables for sensitive configuration
-- ✅ Keep dependencies updated (all CVE-checked as of 2025-12-06)
-- ✅ Minor version locking for supply chain protection
-- 🚧 Implement rate limiting for API endpoints (future)
-- 🚧 Add authentication/API keys (future)
-
-### Testing (Current Coverage: 62%)
-- ✅ Integration tests for API endpoints
-- ✅ Streaming functionality with 20s timeout protection
-- ✅ Async test support with pytest-asyncio
-- ✅ Validate OpenAI API compatibility
-- ✅ Mock responses for all endpoints
-- 🚧 Future: Mock Ollama responses when integrated
-
-### Configuration
-- ✅ Use `.env` files for local development
-- ✅ Document all environment variables in README
-- ✅ Provide sensible defaults where possible
-- ✅ BaseSettings from pydantic-settings
-- 🚧 Support container-based configuration (future)
-
-## Common Patterns
-
-### Streaming Response Pattern (✅ Implemented)
-
-See `src/chat/router.py` for the current implementation:
-
-```python
-from sse_starlette.sse import EventSourceResponse
-from fastapi import FastAPI
-
-async def event_generator():
-    # Currently yields mock lorem ipsum chunks
-    # Future: Stream from Ollama/PydanticAI
-    yield {"data": chunk.model_dump_json()}
-    yield {"data": "[DONE]"}
-
-@app.post("/stream")
-async def stream():
-    return EventSourceResponse(event_generator())
-```
-
-### PydanticAI Agent Pattern (🚧 Future Reference)
-
-For future integration when connecting to Ollama:
-
-```python
-from pydantic_ai import Agent
-
-agent = Agent(
-    'ollama:mistral-nemo',  # Target model
-    # Configuration here
-)
-
-# Use the agent
-result = await agent.run('Your prompt')
-```
-
-### OpenAI-Compatible Response Format (✅ Implemented)
-
-Current implementation in `src/chat/schemas.py`:
-
-```python
-{
-    "id": "chatcmpl-123",
-    "object": "chat.completion.chunk",
-    "created": 1234567890,
-    "model": "mistral-nemo:latest",
-    "choices": [{
-        "index": 0,
-        "delta": {"content": "response"},
-        "finish_reason": None
-    }]
-}
-```

+---
+
+## 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** ✅

+   - British butler personality prompt ✅
+   - Research-oriented mindset ✅
+   - Streaming to reasoning output ✅
+   - Tool calling framework setup ✅
+

+
+### 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

+  ```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)

+
+- **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

+  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
+

+- [ ] 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.
+
+---
+
+## Phase 3: The Butler - Tatlock Agent
+
+**Goal**: Implement the second-tier coordinator with personality within the existing Orchestrator infrastructure

+# Orchestration Scenarios and Tool Flows
+
+This document outlines example scenarios of varying complexity to illustrate the desired orchestration patterns between Tatlock (Butler/Coordinator), expert agents (The Librarian, etc.), and the user.
+
+## Architecture Overview
+
+```
+User Request
+     ↓
+[Steward] → Analyzes request, has visibility into ALL capabilities
+           → Makes routing decision: which experts needed
+           → Passes simplified instruction to Tatlock (not raw tool schemas)
+     ↓
+[Tatlock/Butler] → Coordinator, receives "use Librarian for wiki creation"
+                 → Calls expert agents as tools
+                 → Synthesizes responses into butler-voice answer
+     ↓
+[Expert Agents] → The Librarian, Home Automation, Memory, etc.
+                → Each has their own specialized tools
+                → Return structured results to Tatlock
+     ↓
+[External APIs] → library-desk, home-assistant, user-db, etc.
+```
+
+**Key Principles**:
+
+1. **Steward sees everything** - Has access to all capability descriptions to make informed routing decisions
+2. **Simplified passthrough** - Tatlock receives "delegate to Librarian for research" not 16 tool schemas
+3. **Expert agents are tools** - Tatlock calls `librarian_agent(task)`, not `hybrid_search()` directly
+4. **Each expert owns their tools** - Librarian has wiki tools, Home Automation has device tools
+5. **Results flow up** - Tatlock synthesizes all expert responses into coherent butler answer
+
+---
+
+## Scenario 1: Weather Check (Multi-Step with Memory Lookup)
+
+**User**: "What's the weather like?"
+
+### Complexity Analysis
+
+This seemingly simple request requires:
+1. **Location determination** - Where does the user want weather for?
+2. **Memory/database lookup** - Retrieve user's home location or current location
+3. **Weather data fetch** - Search for weather at determined location
+
+### Flow
+
+```
+1. Steward Analysis
+   → Capabilities needed: memory (user context), tatlock_core (web search)
+   → Complexity: moderate
+   → Note: Location must be determined before weather lookup
+
+2. Tatlock Execution - Step 1
+   <think>User asked about weather but didn't specify location.
+   Checking user profile for home location...</think>
+   → Calls: memory_agent(task: "get user home location")
+   → Memory queries user database
+   → Returns: "User home location: Amsterdam, Netherlands"
+
+3. Tatlock Execution - Step 2
+   <think>User is based in Amsterdam. Fetching current weather...</think>
+   → Calls: search_web("current weather Amsterdam Netherlands")
+   → Receives: "Amsterdam: 12°C, light rain, humidity 78%"
+
+4. Response
+   "Currently 12°C with light rain in Amsterdam, sir. You might want
+   to grab an umbrella if you're heading out."
+```
+
+### Intra-System Prompts
+
+**Steward → Tatlock Note**:
+```
+Weather query - location not specified.
+1. First: Query memory for user's location (home or current)
+2. Then: Search weather for that location
+Capabilities: memory, tatlock_core
+Complexity: moderate
+```
+
+**Tatlock → Memory Agent**:
+```
+Task: Retrieve user's location for weather query.
+Context: User asked about weather without specifying location.
+Action required: Return user's home location or current known location.
+
+Reference (user's original request): "What's the weather like?"
+```
+
+**Memory Agent → Tatlock Response**:
+```
+User location retrieved:
+- Home location: Amsterdam, Netherlands
+- Last known location: Amsterdam (home)
+- Location confidence: high
+- Source: user profile settings
+```
+
+### Alternative Flow: Location Ambiguity
+
+If user has multiple locations or is traveling:
+
+```
+Memory Agent → Tatlock Response:
+  User has multiple locations:
+  - Home: Amsterdam, Netherlands
+  - Office: Rotterdam, Netherlands
+  - Currently traveling: Unknown
+
+  Recommendation: Ask user to clarify or use home location as default.
+```
+
+Tatlock could then either:
+- Ask user: "Shall I check the weather in Amsterdam, sir, or elsewhere?"
+- Default to home: Use Amsterdam and mention the assumption
+
+---
+
+## Scenario 2: Adjust Temperature Based on Weather (Conditional Multi-Expert)
+
+**User**: "Check the weather and if it's cold, turn up the heating"
+
+### Complexity Analysis
+
+This requires:
+1. **Location lookup** - Where to check weather (implicit: user's home)
+2. **Weather fetch** - Get current outdoor temperature
+3. **Conditional evaluation** - Is it "cold"? (requires threshold judgment)
+4. **Home automation** - Adjust heating if condition met
+
+### Flow
+
+```
+1. Steward Analysis
+   → Capabilities needed: memory, tatlock_core, home_automation
+   → Complexity: moderate
+   → Note: Conditional logic - heating only if cold
+   → Sequence: location → weather → evaluate → (maybe) heating
+
+2. Tatlock Execution - Step 1
+   <think>Need to check weather at user's location first...</think>
+   → Calls: memory_agent(task: "get user home location")
+   → Returns: "Amsterdam, Netherlands"
+
+3. Tatlock Execution - Step 2
+   <think>Fetching weather for Amsterdam...</think>
+   → Calls: search_web("current weather Amsterdam Netherlands")
+   → Receives: "Current temperature: 8°C, cloudy, wind 15km/h"
+
+4. Tatlock Evaluation
+   <think>Temperature is 8°C - that's cold by most standards.
+   User requested heating adjustment if cold. Will proceed...</think>
+
+5. Tatlock Execution - Step 3
+   <think>Delegating heating adjustment to Home Automation...</think>
+   → Calls: home_automation_agent(task)
+   → Home Automation executes: set_thermostat(temperature=21)
+   → Receives: "Thermostat set to 21°C"
+
+6. Response
+   "It's rather brisk outside at 8°C, sir. I've taken the liberty of raising
+   the heating to a comfortable 21°C. The house should warm up shortly."
+```
+
+### Intra-System Prompts
+
+**Steward → Tatlock Note**:
+```
+Conditional weather-to-heating request.
+1. Get user location from memory
+2. Check weather at location
+3. IF cold (suggest: below 15°C): delegate to home_automation to increase heating
+4. IF not cold: inform user, no action needed
+Capabilities: memory, tatlock_core, home_automation
+Complexity: moderate (conditional)
+```
+
+**Tatlock → Home Automation Agent**:
+```
+Task: Increase heating due to cold weather conditions.
+Context: Current outdoor temperature is 8°C in Amsterdam. User requested
+heating adjustment if cold - condition is met.
+Action required: Set thermostat to comfortable temperature (recommend 21°C).
+
+Reference (user's original request): "Check the weather and if it's cold, turn up the heating"
+```
+
+**Home Automation → Tatlock Response**:
+```
+Action completed: Thermostat adjusted
+- Previous setting: 18°C
+- New setting: 21°C
+- Zone: All zones (whole house)
+- Estimated time to reach target: 15 minutes
+- Note: Eco mode disabled temporarily for faster heating
+```
+
+### Alternative Flow: Not Cold
+
+```
+Weather returns: "Current temperature: 18°C, partly sunny"
+
+Tatlock Evaluation:
+<think>18°C isn't cold - no heating adjustment needed.
+Will inform user that conditions don't warrant heating...</think>
+
+Response:
+"It's a pleasant 18°C outside, sir - not particularly cold.
+I don't believe the heating requires adjustment, but do let
+me know if you'd like it warmer regardless."
+```
+
+---
+
+## Scenario 3: Adjust Lights Based on Time (Conditional Logic)
+
+**User**: "Set the lights appropriately for the time of day"
+
+### Flow
+
+```
+1. Steward Analysis
+   → Capabilities needed: tatlock_core (datetime), home_automation
+   → Complexity: moderate
+
+2. Tatlock Execution - Step 1
+   <think>Checking current time to determine appropriate lighting...</think>
+   → Calls: get_current_datetime()
+   → Receives: "2024-12-11 21:45"
+
+3. Tatlock Evaluation
+   <think>It's evening (21:45). Will set warm, dimmed lighting for wind-down time...</think>
+
+4. Tatlock Execution - Step 2
+   → Calls: home_automation_agent(task)
+   → Home Automation executes: set_scene("evening_relaxation")
+   → Receives: "Scene 'evening_relaxation' activated - warm white 40%"
+
+5. Response
+   "It's quarter to ten in the evening, sir. I've set the lights to a warm,
+   subdued glow - ideal for winding down. Shall I also draw the curtains?"
+```
+
+### Intra-System Prompts
+
+**Tatlock → Home Automation Agent**:
+```
+Task: Set lighting appropriate for current time of day.
+Context: Current time is 21:45 (evening). User wants lights adjusted automatically.
+Action required: Activate appropriate lighting scene for evening/night.
+
+Reference (user's original request): "Set the lights appropriately for the time of day"
+```
+
+---
+
+## Scenario 4: Create a Reminder (Simple Expert Delegation)
+
+**User**: "Remind me to call the dentist tomorrow at 2pm"
+
+### Flow
+
+```
+1. Steward Analysis
+   → Capabilities needed: personal_assistant (reminders)
+   → Complexity: simple
+
+2. Tatlock Execution

+```
+
+### Tatlock's Final Response Pattern
+
+1. **Acknowledge** - Confirm understanding of the request
+2. **Summarize actions** - What was done, by whom (implicitly)
+3. **Key details** - Important information the user should know
+4. **Proactive offer** - Suggest related actions or follow-ups
+5. **Butler voice** - Formal but warm, with personality
+
+### Expert Agent Response Pattern
+
+1. **Task status** - Completed/Partial/Failed
+2. **Action summary** - What was done
+3. **Key data** - Information Tatlock needs to synthesize
+4. **Metadata** - IDs, counts, timestamps for reference
+5. **Suggestions** - Optional follow-up actions
+
+---
+
+## Error Handling Scenarios
+
+### Expert Agent Failure
+
+```
+Tatlock → Librarian: "Create wiki page about quantum computing"
+Librarian → Tatlock: "Error: library-desk API unavailable (connection timeout)"
+
+Tatlock Response:
+"I'm afraid The Librarian is having some difficulty reaching the wiki
+service at the moment, sir. I can attempt a basic web search on quantum
+computing if you'd like, or we can try the wiki operation again in a
+few minutes."
+```
+
+### Partial Completion
+
+```
+User: "Create a reminder and add it to my calendar"
+
+Tatlock → PA: Create reminder
+PA → Tatlock: "Reminder created successfully"
+
+Tatlock → Calendar: Add to calendar
+Calendar → Tatlock: "Error: Calendar sync not configured"
+
+Tatlock Response:
+"I've created the reminder, sir, but I wasn't able to add it to your
+calendar - it appears the calendar integration needs to be configured.
+The reminder will still alert you at the scheduled time. Shall I help
+set up the calendar connection?"
+```
+
+---
+
+## Summary: Key Design Principles
+
+1. **Tatlock is the orchestrator** - Never exposes raw tool complexity to users
+2. **Expert agents are tools** - Tatlock calls them, they return structured responses
+3. **Context flows down** - Each expert gets only what they need to complete their task
+4. **Results flow up** - Tatlock synthesizes all responses into coherent butler-voice answer
+5. **Think updates maintain engagement** - User sees progress during complex operations
+6. **Errors are handled gracefully** - Tatlock explains and offers alternatives
+7. **Proactive suggestions** - Tatlock anticipates follow-up needs

+
+This document should remain stable, serving as the north star for development decisions.
+
+---
+
+## Introduction
+
+### Vision
+
+Tatlock is a comprehensive homelab butler and personal assistant system designed to augment personal and household productivity through intelligent automation, knowledge management, and contextual assistance. Named after a traditional British butler, Tatlock embodies the wit, competence, and organizational skill of a well-run household staff, coordinating a team of specialized expert agents to serve the needs of its users.
+
+Unlike cloud-dependent AI assistants, Tatlock is built to operate primarily offline, maintaining privacy and control while providing sophisticated assistance across multiple domains of daily life.
+
+### Purpose
+
+The system serves as a unified intelligent interface for:
+
+- **Knowledge Work**: Research assistance, information synthesis, general knowledge queries
+- **Technical Work**: Software development support, systems administration tasks
+- **Home Management**: Home automation control and monitoring
+- **Personal Organization**: Calendaring, scheduling, task management, list keeping
+- **Information Management**: Personal documentation, note-taking, knowledge base maintenance
+
+### Core Philosophy
+
+Tatlock is built on three fundamental principles:
+
+1. **Privacy-First Architecture**: All processing occurs locally within your homelab environment. Your data, conversations, and personal information never leave your infrastructure unless you explicitly direct it to do so.
+
+2. **Offline-Capable Operation**: While the system can leverage internet resources when available, core functionality remains operational without external connectivity. This ensures reliability and independence from third-party services.
+
+3. **Multi-Tenant by Design**: Though primarily intended for personal use (yourself, household members, and close friends), the system architecture supports multiple users with complete data isolation, personalized experiences, and individual preferences.
+
+### Scope
+
+**Current Focus**: The initial implementation establishes the foundational architecture with OpenAI-compatible API interfaces, structured response formats, and reasoning transparency. This phase prioritizes:
+- Core API infrastructure
+- Response streaming and formatting
+- Basic conversation management
+- Testing and validation framework
+
+**Future Expansion**: The system will evolve into a comprehensive personal assistant platform by integrating:
+- Specialized containerized services (machine learning, search, storage, memory)
+- Task and project management capabilities
+- Calendar and scheduling systems
+- Home automation integration
+- Personal knowledge management
+- Advanced multi-agent collaboration
+
+### Deployment Model
+
+Tatlock is designed for **single-instance, multi-user deployment** within a homelab environment:
+
+- **Users**: Personal use for household members and trusted friends
+- **Infrastructure**: Self-hosted on your own hardware
+- **Architecture**: Containerized microservices on a single host
+- **Data Sovereignty**: Complete control over all data and processing
+
+This deployment model balances simplicity of operation with the security and personalization needs of a small, trusted user base.
+
+### System Context
+
+Tatlock operates as the central orchestration layer within a broader ecosystem of containerized services:
+
+#### Core Service Stack
+- **Language Models**: Ollama for local ML inference
+- **Search**: SearxNG for privacy-respecting web search
+- **Memory Systems**:
+  - Redis for short-term memory and caching
+  - Qdrant for long-term memory and vector storage
+- **Data Storage**: PostgreSQL for structured data and multi-tenant isolation
+- **Future Services**: Calendaring, scheduling, task management, documentation systems
+
+#### Integration Approach
+Rather than building monolithic functionality, Tatlock acts as an intelligent coordinator, leveraging specialized services for specific capabilities while maintaining consistent interfaces and user experience.
+
+### Design Goals
+
+1. **Unified Experience**: Single point of interaction for diverse personal assistance needs
+2. **Contextual Intelligence**: Understanding across conversations, tasks, and time
+3. **Transparent Operation**: Visible reasoning and decision-making processes
+4. **Extensible Architecture**: Easy integration of new capabilities and services
+5. **Reliable Performance**: Consistent operation regardless of internet availability
+6. **User Privacy**: Zero data leakage to external parties
+7. **Multi-User Support**: Isolated experiences for different household members
+
+### Success Criteria
+
+Tatlock succeeds when it becomes the natural first point of interaction for:
+- Answering questions and conducting research
+- Managing daily tasks and schedules
+- Controlling home automation
+- Supporting development and technical work
+- Organizing personal information and knowledge
+
+The system should feel less like "using a tool" and more like "asking a capable assistant" who understands your context, preferences, and needs.
+
+## The Household Architecture
+
+### System Layers
+
+The Tatlock system consists of two distinct architectural layers:
+
+#### The Orchestrator (Infrastructure Layer)
+
+The **Orchestrator** is the FastAPI application that provides the technical infrastructure:
+- HTTP/SSE endpoints (`/v1/responses`, `/v1/chat/completions`)
+- Streaming coordination and conversation management
+- Token counting and context window management
+- Integration with Open WebUI and other clients
+- Request/response lifecycle management
+
+This is the "plumbing" layer that exists now and handles all the technical concerns of running an OpenAI-compatible API.
+
+#### Tatlock - The Butler (Agent Layer)
+
+**Tatlock** is the PydanticAI agent that provides the intelligence and personality:
+- The witty British butler persona
+- Coordination with the Steward and household staff
+- Multi-agent orchestration and synthesis
+- Context-aware, personalized responses
+
+The Orchestrator hosts Tatlock—users interact with "Tatlock" (the advertised model name), but technically they're talking to the Orchestrator infrastructure which routes requests through the Tatlock agent.
+
+**Current State**: The Orchestrator exists and uses mock agents. Phase 1-3 of the implementation roadmap will integrate the real Tatlock agent using PydanticAI.
+
+### The British Household Metaphor
+
+Tatlock adopts the organizational structure of a traditional British estate household, where specialized staff members handle distinct domains of responsibility under the coordination of a capable butler. This metaphor is not merely aesthetic—it reflects a deliberate architectural pattern that enables focused expertise, clear separation of concerns, and efficient coordination.
+
+### Household Roles
+
+#### Tatlock - The Butler (Primary Interface)
+
+**Character**: Witty, capable, and impeccably organized
+**Role**: Chief coordinator and primary point of contact with users
+
+Tatlock serves as the face of the system, managing all user interactions with personality and competence. He understands the full context of requests, coordinates with appropriate household staff, synthesizes their contributions, and delivers coherent, thoughtful responses. His wit and personality make interactions engaging while maintaining professionalism.
+
+**Responsibilities**:
+- Receiving and understanding user requests
+- Coordinating with household staff (expert agents)
+- Synthesizing multi-source information into coherent responses
+- Maintaining conversation context and user preferences
+- Presenting results with appropriate personality and tone
+
+#### The Steward (Request Analysis)
+
+**Role**: Initial request triage and resource planning
+
+Before Tatlock engages with a request, the Steward performs crucial preparatory work. The Steward analyzes incoming requests to determine which tools, services, and household staff members will be needed, creating a curated recommendation that streamlines Tatlock's work.
+
+**Responsibilities**:
+- Analyzing user requests for required capabilities
+- Identifying relevant tools and expert agents
+- Providing recommendations to focus Tatlock's attention
+- Reducing cognitive load on the Butler by pre-filtering options
+
+#### Expert Household Staff (Domain Specialists)
+
+**The Handyman** - System Maintenance and Technical Operations
+Handles system administration, server management, infrastructure monitoring, and technical troubleshooting.
+
+**The Housekeeper** - Home Automation Management
+Controls and monitors home automation systems, environmental controls, security, and physical space management.
+
+**The Secretary** - Scheduling and Organization
+Manages calendars, appointments, scheduling conflicts, reminders, and time-based coordination.
+
+**The Developer** - Software Development Support
+Assists with code writing, debugging, architecture decisions, documentation, and development workflows.
+
+**Additional Staff** (Future):
+- The Librarian - Knowledge management and research
+- The Accountant - Financial tracking and analysis
+- The Chef - Meal planning and nutrition
+- Others as needs emerge
+
+### The Two-Tier Request Flow
+
+The household operates through a carefully orchestrated two-tier process:
+
+#### Tier 1: The Steward's Preparation
+
+1. **User request arrives** at the Orchestrator (via HTTP API)
+2. **Orchestrator routes** the raw request to the Steward for analysis
+3. **Steward determines** which tools and household staff are relevant
+4. **Steward prepares recommendations**, written as a note to Tatlock
+5. **Recommendations are prepended** to the user's request
+
+**Purpose**: This separation ensures that Tatlock isn't overwhelmed with the full universe of available tools and agents. The Steward narrows the scope to only relevant capabilities, making Tatlock's decision-making cleaner and more focused.
+
+#### Tier 2: Tatlock's Orchestration
+
+1. **Tatlock receives** the enriched request (original + Steward's notes)
+2. **Scope is limited** to recommended tools and staff only
+3. **Tatlock coordinates** with appropriate household members
+4. **Expert agents perform** their specialized tasks
+5. **All interactions are streamed** to the reasoning output in real-time
+6. **Tatlock synthesizes** results into a coherent response
+7. **User receives** a unified answer from Tatlock
+
+**Purpose**: This tier focuses on execution and coordination. With a curated set of tools, Tatlock can efficiently orchestrate multiple expert agents, combine their outputs, and present a seamless response to the user.
+
+**Real-Time Transparency**: Every interaction—whether Tatlock consulting the Handyman, waiting for a database query, or receiving results from the Secretary—is piped directly into the orchestrator's reasoning output. Users see the household at work in real-time, understanding what's happening even when operations take time. This transforms potentially frustrating wait times into engaging insight into the system's thought process.
+
+### Why This Architecture Works
+
+#### Focused Expertise
+Each household member (expert agent) receives highly specific prompts tailored to their domain. Rather than a single overly-broad prompt trying to do everything, specialized agents work within their areas of competence.
+
+#### Cognitive Load Management
+By pre-filtering tools and agents, the Steward prevents Tatlock from being overwhelmed with options. This is analogous to how a real butler doesn't personally know every detail of every household operation—they know whom to ask.
+
+#### Transparent Coordination
+The Steward's recommendations are visible in the thinking flow, keeping users informed about which household staff are being consulted. This transparency builds trust and understanding.
+
+#### Composable Capabilities
+New expert agents can be added to the household without overwhelming the core system. The Steward learns about new staff members and includes them in recommendations when appropriate.
+
+#### Model Efficiency
+Rather than requiring a single enormous context window containing all possible tools and capabilities, the system makes targeted calls with focused contexts. This is more efficient and produces better results.
+
+**Unified Base Model**: All household members—the Steward, Tatlock, and expert agents—use the same base language model by default. This ensures the model stays loaded in VRAM, eliminating loading delays between calls and maximizing response speed.
+
+**Specialized Models When Needed**: Individual household staff may invoke specialized models for domain-specific tasks when appropriate:
+- The Developer might use Codestral for complex code generation
+- Future visual agents might use vision-language models
+- Future audio agents might use speech-specific models
+
+The decision to use a specialized model is made by the household member responsible for that domain, based on the specific requirements of their task. This balances efficiency (keeping the base model hot) with capability (accessing specialized models when they provide significant advantage).
+
+### Personality and Interaction
+
+While the underlying architecture is sophisticated, users interact solely with **Tatlock**, who maintains a consistent personality:
+
+- **Witty but helpful**: Responses may include clever observations or light humor
+- **Competent and organized**: Always knows who to ask and how to coordinate
+- **Context-aware**: Remembers ongoing conversations and user preferences
+- **Transparent**: Explains which household staff are being consulted when relevant
+- **Professional**: Despite the wit, maintains respect and helpfulness
+
+The user never directly interacts with the Steward or individual expert agents—those are internal household operations that Tatlock manages on their behalf.

 ### Conversation History
 
-Optional conversation tracking via metadata:
+Optionally track conversations using metadata:
 
 ```bash
 curl http://localhost:8000/v1/responses \
   -H "Content-Type: application/json" \
   -d '{

-    }
+    "input": [{"role": "user", "content": "Hello"}],
+    "metadata": {"conversation_id": "conv_abc123"}
   }'
 ```
 
-**Hybrid Approach:**
-- Client MUST send full conversation history in `input` array (OpenAI compatible)
-- Server optionally tracks via `metadata.conversation_id` (for analytics, future vector memory)
-- Auto-generates conversation ID from first message hash if not provided
+**Note**: Client must send full conversation history in `input` array (OpenAI compatible). Server optionally tracks via `metadata.conversation_id` for future features.
 
-### Interactive Documentation
+### Using Tatlock with Tools
 
-- **Swagger UI**: `http://localhost:8000/docs`
-- **ReDoc**: `http://localhost:8000/redoc`
+Tatlock automatically uses his permanent tools when appropriate:
+
+```bash
+# Mathematical calculation
+curl http://localhost:8000/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "Tatlock",
+    "messages": [{"role": "user", "content": "What is sqrt(144) + 25?"}]
+  }'
+
+# Date/time queries
+curl http://localhost:8000/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "Tatlock",
+    "messages": [{"role": "user", "content": "What was the date 2 weeks ago?"}]
+  }'
+
+# Web search for current information
+curl http://localhost:8000/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "Tatlock",
+    "messages": [{"role": "user", "content": "Search for recent Python 3.12 features"}]
+  }'
+```
+
+**Tatlock's Tool Usage Philosophy:**
+- Uses calculator for ALL mathematics (even simple arithmetic)
+- Uses date/time tools instead of guessing dates
+- Searches for current/volatile information to verify facts
+- Maintains a researcher's mindset with tool-assisted verification

 ### Testing Error Handling
 
-Lorem-tester supports error triggers:
-- **"trigger_rate_limit"** - Simulates rate limit error
-- **"trigger_context_overflow"** - Simulates context length error
+Use special triggers in user messages:

-### Code Style
-
-- **Async-first**: All I/O operations use async/await
-- **Type hints**: All functions fully typed
-- **Pydantic validation**: All request/response validation
-- **Domain separation**: Clear boundaries between components
-- **Single responsibility**: Each module has one clear purpose

-### Version Locking
-
-Minor version locking (`>=X.Y,<X.(Y+1)`) for security:
-- Allows patch updates
-- Blocks potentially breaking minor updates
-- All dependencies checked for CVEs (2025-12-06)
-
-### Best Practices
-
-1. Never commit `.env` files
-2. Use environment variables for sensitive config
-3. Keep dependencies updated monthly
-4. Validate all inputs with Pydantic
-5. Use HTTPS in production
-6. Implement rate limiting

 ## Troubleshooting
 
-### Common Issues
-
-**Streaming not working:**
+### Streaming not working
 - Verify SSE-Starlette is installed
 - Check client supports Server-Sent Events
 - Test with: `pytest tests/responses/ -k streaming`
 
-**Open WebUI can't connect:**
+### Open WebUI can't connect
 - Use Docker bridge gateway IP: `172.17.0.1:8000`
 - Check firewall settings
 - Verify server is running on `0.0.0.0`
 
-**Tests failing:**
-- Install test dependencies: `pip install -r requirements-dev.txt`
-- Activate virtual environment
-- Run with verbose: `pytest -v`
-
-**Reasoning not showing:**
+### Reasoning not showing
 - Ensure using Chat Completions endpoint (auto-enables reasoning)
 - Or manually enable in Responses API: `"reasoning": {"effort": "medium", "summary": "auto"}`
 - Check Open WebUI version supports `<think>` tags
 
-## Future Roadmap
+### Tatlock agent errors
+- Verify Ollama is running: `curl http://localhost:11434/api/tags`
+- Check model is downloaded: `ollama list`
+- Review environment variables: `OLLAMA_HOST`, `OLLAMA_DEFAULT_MODEL`
+- Check logs: `tail -f logs/server.log`
 
-### Short-term
-- [ ] Connect tatlock model to real PydanticAI agent
-- [ ] Implement vector memory (Qdrant integration)
-- [ ] Add authentication/API keys
-- [ ] Rate limiting middleware
+### Web search not working
+- Verify SearXNG is running: `curl http://localhost:8087/`
+- Check `SEARXNG_HOST` environment variable
+- SearXNG is optional - Tatlock will note if search is unavailable
 
-### Long-term
-- [ ] Multi-model support (OpenAI, Anthropic, etc.)
-- [ ] Advanced conversation memory
-- [ ] Tool/function calling integration
-- [ ] Usage tracking and analytics

+- Personal facts (vehicle, pets, family members, hobbies, interests)
+- Life details (employer, occupation, significant events)
+- Profile information (name, location, timezone)
+- Preferences (units, theme, communication style)
+
+## Your Character
+
+You are a discreet and attentive chronicler. Like a personal biographer who has been
+with the household for years, you:
+- Listen carefully and remember important details
+- Recall information accurately when asked
+- Never gossip or volunteer unnecessary information
+- Respect privacy absolutely
+- Acknowledge when you don't know something rather than guessing
+
+## Your Tools
+
+### Recalling the Story
+- **recall_semantic**: Your primary tool for answering questions about the user
+  - "What car do I drive?" → searches for car-related memories
+  - "Where do I work?" → finds employment information
+  - Finds relevant memories even without exact keywords
+- **list_memories**: Browse all recorded memories of a type
+  - Use when user asks "What do you know about me?"
+  - Shows everything you've recorded
+
+### Recording New Details
+- **store_insight**: Record new facts from conversation
+  - User says "My car is a Tesla" → store_insight("car", "Tesla Model 3")
+  - User says "I work at Acme" → store_insight("employer", "Acme Corp")
+  - Use for facts that don't fit standard profile fields
+- **update_profile**: Update core biographical fields
+  - name, location, timezone only
+  - "I live in Amsterdam" → update_profile("location", "Amsterdam")
+- **update_preference**: Record user preferences
+  - temperature_unit, distance_unit, theme, etc.
+  - "Use Celsius please" → update_preference("temperature_unit", "celsius")
+
+### Managing Records
+- **forget_memory**: Remove specific records
+  - User asks to forget something → honor immediately
+  - Information becomes outdated → remove it
+
+## Guidelines
+
+### What to Record
+- Explicit statements: "I drive a Tesla", "My wife is Sarah"
+- Corrections: "Actually, I moved to Berlin"
+- Preferences: "I prefer metric units"
+
+### What NOT to Record
+- Sensitive data: passwords, financial details, health information
+- Temporary information: "I'm tired today"
+- Speculation or assumptions
+
+### Responding to Tatlock
+Your responses go to Tatlock (the butler) who synthesizes the final answer. Be:
+- Direct and factual
+- Clear about what you found or didn't find
+- Structured for easy integration with other responses
+
+When you don't have information:
+"I have no record of the user's [topic]. Would you like me to record this information?"
+
+When recalling:
+"According to my records, [information]. This was recorded [source/when if available]."

+- The personal wiki (Wiki.js) containing documentation and notes
+- The knowledge graph (Neo4j) with entities and relationships
+- Vector embeddings (Qdrant) for semantic search
+- Web search (SearXNG) for current information
+
+## Your Personality
+- Scholarly and thorough in your research
+- Cite your sources and provide context
+- Organize information clearly
+- Suggest related topics when relevant
+- Acknowledge limitations when information is incomplete
+
+## Your Tools
+
+### Research Tools
+- **hybrid_search**: Your primary research tool - searches all sources at once
+- **search_wiki**: Find specific wiki pages by keyword
+- **semantic_search**: Find conceptually similar content
+- **explore_knowledge_graph** / **find_related_entities**: Discover connections
+- **list_dossiers** / **get_dossier_pages**: Browse knowledge collections
+
+### Wiki Reading Tools
+- **get_wiki_page**: Read full content of a wiki page by ID
+  - ALWAYS use this to fetch and read page content when summarizing
+  - Use after search_wiki to get the full text of a specific page
+
+### Wiki Writing Tools
+- **smart_create_wiki_page**: Create a page with automatic research (PREFERRED)
+  - **This is the DEFAULT choice when user asks to create a wiki page about a topic**
+  - When user says "Create a page about X" or "Add X to the wiki" without providing specific content, ALWAYS use this tool
+  - Automatically researches the topic from wiki, graph, and web
+  - Synthesizes content with proper source attribution
+  - Creates bidirectional links in knowledge graph
+- **create_wiki_page**: Create a page with user-provided content
+  - ONLY use when user provides specific text/content they want added verbatim
+  - For simple notes, reminders, or quick additions with exact content
+- **update_wiki_page**: Update an existing page (partial updates)
+  - Use when: "Update the page about X", "Fix this info", "Add to dossier"
+  - First search_wiki to find the page, then get_wiki_page to read it
+  - Only specify fields you want to change
+
+## Research Approach
+1. Start with hybrid_search for broad queries
+2. Use search_wiki for specific document lookups
+3. **ALWAYS use get_wiki_page to fetch full content** before summarizing a page
+4. Use semantic_search when looking for conceptually similar content
+5. Explore the knowledge graph to find connections between concepts
+6. Synthesize and summarize findings clearly
+
+## Writing Approach
+When asked to create or update wiki content:
+1. **"Create a page about X" (no specific content provided)**: Use smart_create_wiki_page
+   - This is the PREFERRED tool for topic-based page creation
+   - It researches first and creates comprehensive, well-sourced content
+2. **User provides exact text to add**: Use create_wiki_page with their content
+3. **Updating existing pages**:
+   - Search for the page with search_wiki

+## Response Format
+Your responses are returned to Tatlock (the butler) who will synthesize them into a final answer for the user. Keep this in mind:
+- Lead with the key findings or confirmation of action
+- Include relevant sources and citations
+- When summarizing wiki pages, fetch and read them first
+- Note any gaps in available information
+- Be concise but thorough - Tatlock will format the final response
+- Structure your findings clearly so they can be easily integrated with other responses

+
+Key pattern: Stream user-facing interactions, use run() internally
+to avoid Ollama streaming+tool call bugs.
+
+Supports:
+- Single expert delegation with think updates
+- Sequential multi-expert execution (task A → task B → task C)
+- Parallel multi-expert execution (tasks A, B, C concurrently)
+- Result aggregation from multiple experts
+- Partial failure handling

+- Math/calculations → tatlock_core
+- Quick web searches → tatlock_core
+- Time/date queries → tatlock_core
+- Wiki creation ("create a page about X", "add X to wiki") → librarian with smart_create
+- Wiki updates ("update the page", "add to dossier") → librarian with update
+- Research queries ("find info", "what do we know about", "search for") → librarian with hybrid_search
+- In-depth research, knowledge synthesis, document lookup → librarian with hybrid_search
+- If conversation history is relevant, note which previous turns matter
+- Assess complexity: simple (1 tool), moderate (2-3 tools), complex (multiple steps)

+
+Address users as "sir" and maintain a formal yet personable tone. You are not overly apologetic and may be slightly snarky when appropriate. If an opportunity for a pun presents itself, you cannot resist.
+
+You coordinate with various household staff (expert agents) to provide comprehensive assistance across:
+- Research and knowledge work
+- Software development
+- System administration
+- Home automation
+- Personal organization
+
+## Research Mindset
+
+Approach all questions with a researcher's mindset:
+- Always verify facts rather than relying solely on memory
+- When unsure, search for current and accurate information
+- Cross-check important claims when possible
+- Acknowledge uncertainty and seek verification
+- Prefer authoritative sources and current data
+
+## Available Tools
+
+You have direct access to several permanent tools that you should USE whenever appropriate:
+
+1. **Calculator** (calculate): For ALL mathematical operations, no matter how simple
+   - Always prefer using the calculator over mental math
+   - Supports arithmetic, algebra, trigonometry, logarithms, and common math functions
+   - Example: "What is 234 * 567?" -> Use calculate("234 * 567")
+
+2. **Date/Time Toolkit**:
+   - get_current_datetime: Get the current date and/or time
+   - calculate_time_offset: Calculate dates relative to now (e.g., "1 week ago", "3 months from now")
+   - time_difference: Calculate the time between two dates
+   - Use these for ANY date/time queries - never guess at dates or times
+
+3. **Web Search** (search_web): Search for current, volatile, or factual information
+   - Use this for ANY information that might be current, factual, or outside your training data
+   - Examples: news, current events, recent developments, specific facts, technical documentation
+   - Always prefer searching over guessing or using potentially outdated knowledge
+   - For extensive research questions, note that this will later be delegated to the librarian
+
+## Tool Usage Guidelines
+
+- **Mathematics**: ALWAYS use the calculator tool, even for simple arithmetic
+- **Dates/Times**: ALWAYS use the date/time tools, never guess or estimate
+- **Current Information**: ALWAYS search for facts, news, or volatile information
+- **Verification**: When facts are important, use search to verify rather than rely on memory alone
+- When you use a tool, explain what you're doing in a butler-appropriate manner
+- Present tool results naturally in your response
+
+Currently in Phase 1 development - expert agent delegation will be added in later phases.

+# End-to-End API Tests
+
+These tests make real HTTP requests to the running Tatlock API server to verify the complete stack works correctly.
+
+## Prerequisites
+
+1. **Server must be running** on `http://localhost:8000`
+2. **Ollama must be running** with `mistral-nemo:latest` model
+3. **Redis must be running** (for benchmarking)
+
+## Running the Tests
+
+### Start the server first:
+
+```bash
+# Terminal 1: Start the server
+uvicorn src.main:app --reload
+```
+
+### Run the E2E tests:
+
+```bash
+# Terminal 2: Run E2E tests
+PYTHONPATH=/mnt/media/Projects/tatlock pytest tests/e2e/ -v
+```
+
+### Run specific test categories:
+
+```bash
+# Test chat completions only
+pytest tests/e2e/test_api_endpoints.py::TestChatCompletionsE2E -v
+
+# Test responses API only
+pytest tests/e2e/test_api_endpoints.py::TestResponsesAPIE2E -v
+
+# Test streaming only
+pytest tests/e2e/test_api_endpoints.py::TestStreamingE2E -v
+
+# Test Steward integration specifically
+pytest tests/e2e/test_api_endpoints.py::TestStewardIntegration -v
+```
+
+## What These Tests Verify
+
+### 1. Chat Completions Endpoint (`/v1/chat/completions`)
+
+- ✅ Simple calculations trigger calculator tool
+- ✅ Search queries trigger web search
+- ✅ Multi-turn conversations maintain context
+- ✅ Complex requests use multiple tools
+- ✅ Simple greetings don't trigger unnecessary tools
+- ✅ Date/time queries trigger datetime tools
+
+### 2. Responses API Endpoint (`/v1/responses`)
+
+- ✅ Reasoning output includes Steward's analysis
+- ✅ Multi-turn conversations show in Steward reasoning
+- ✅ Response structure follows OpenAI Responses format
+
+### 3. Streaming
+
+- ✅ Chat completions streaming works
+- ✅ Steward reasoning appears in stream
+- ✅ Proper SSE format with chunks
+
+### 4. Error Handling
+
+- ✅ Invalid model returns 404
+- ✅ Missing required fields return 422
+- ✅ Invalid parameters return 422
+
+### 5. Steward Integration
+
+- ✅ Steward recommends correct capabilities
+- ✅ Steward detects conversation context
+- ✅ Steward analysis appears in all responses
+
+## Expected Behavior
+
+When tests run, you should see in the server logs:
+
+```
+INFO     creating_response_with_steward
+INFO     preprocessing_request
+INFO     operation_started             operation=steward_analysis
+INFO     steward_analysis_complete     recommended=[...] complexity=simple
+INFO     tatlock_run_with_scoped_tools
+INFO     tatlock_response_generated
+INFO     tool_tracking_finalized
+```
+
+## Test Scenarios
+
+### Simple Calculation
+```
+User: "What is 144 divided by 12?"
+Expected: Calculator tool used, answer is "12"
+```
+
+### Web Search
+```
+User: "What is the capital of France?"
+Expected: Search may be used, answer mentions "Paris"
+```
+
+### Multi-Turn
+```
+User: "What is 15 times 4?"
+Assistant: "60"
+User: "Now add 20 to that result."
+Expected: Context recognized, answer is "80"
+```
+
+### Combined Tools
+```
+User: "Calculate the square root of 256, then search for what number squared equals that result."
+Expected: Both calculator and search recommended
+```
+
+### Date/Time
+```
+User: "What is today's date?"
+Expected: Datetime tool used, current date returned
+```
+
+## Troubleshooting
+
+### Tests fail with connection error
+
+Make sure the server is running:
+```bash
+uvicorn src.main:app --reload
+```
+
+### Tests timeout
+
+- Check that Ollama is running and responsive
+- Increase timeout in test file if needed (default: 60s)
+
+### Tool usage not detected
+
+- Check server logs to see if tools are actually being called
+- Verify Steward preprocessing is happening (look for `steward_analysis` logs)
+
+### Inconsistent results
+
+- LLM responses can vary - tests check for key indicators rather than exact text
+- If a test occasionally fails, it might be due to LLM variance
+- Check the actual response content in the test output
+
+## Coverage
+
+These tests complement the unit and integration tests by:
+
+1. **Testing the full HTTP stack** - Request parsing, routing, middleware
+2. **Testing real LLM behavior** - Not mocked, actual Ollama responses
+3. **Testing real tool execution** - Calculator, datetime, search actually run
+4. **Testing Steward preprocessing** - Real analysis and tool scoping
+5. **Testing error handling** - HTTP error codes and error responses
+
+Together with unit/integration tests, this provides comprehensive coverage of the entire system.
