+### Added
+
+#### Phase 3: Butler Orchestration (Multi-Agent Coordination)
+- **The Librarian Agent**: Expert agent for research and knowledge management
+  - PydanticAI agent with specialized research assistant personality
+  - Connects to library-desk API for HybridRAG capabilities
+  - System prompt emphasizes fetching wiki pages before summarizing
+  - Streaming support via `run_librarian_stream()`
+
+- **Library-Desk API Client** (`src/agents/librarian/client.py`):
+  - Async HTTP client with httpx for library-desk API integration
+  - HybridRAG search (vector + graph + web search)
+  - Wiki operations (search, get, list, create, update pages)
+  - Smart page creation with HybridRAG research (`POST /wiki/pages/smart-create`)
+  - Semantic vector search
+  - Knowledge graph queries (Cypher execution)
+  - Dossier (tag collection) browsing
+  - Health check endpoint
+
+- **Librarian Tools** (`src/agents/librarian/tools.py`):
+  - Research tools:
+    - `hybrid_search`: Combined vector, graph, and web search
+    - `search_wiki`: Full-text wiki page search
+    - `get_wiki_page`: Fetch full wiki page content by ID
+    - `semantic_search`: Vector similarity search
+    - `list_dossiers`: Browse knowledge collections
+    - `get_dossier_pages`: Get pages in a dossier
+    - `explore_knowledge_graph`: Entity and relationship discovery
+    - `find_related_entities`: Find connected concepts
+  - Write tools:
+    - `smart_create_wiki_page`: Create page with automatic HybridRAG research (PREFERRED for topic-based creation)
+    - `create_wiki_page`: Create page with user-provided content
+    - `update_wiki_page`: Update existing page (partial updates supported)
+
+- **Agent Communication Protocol** (`src/agents/protocol.py`):
+  - `AgentRequest`: Standardized task request with context and constraints
+  - `AgentResponse`: Response with result, reasoning, tool calls, confidence
+  - `DelegationIntent`: Routing intent with target agent and reason
+  - `CoordinationResult`: Aggregated multi-agent results
+  - `DelegationReason` enum: domain expertise, tool access, resource efficiency, user preference
+  - Error types: `AgentError`, `AgentTimeoutError`, `AgentUnavailableError`
+
+- **Coordination Engine** (`src/agents/coordination.py`):
+  - `CoordinationEngine`: Multi-agent task orchestration
+  - Routing tasks to appropriate expert agents
+  - Sequential and parallel execution support
+  - Result aggregation from multiple agents
+  - Graceful error handling and degradation
+  - Streaming delegation support
+  - Convenience functions: `delegate_to_librarian()`, `delegate_to_librarian_stream()`
+
+- **Librarian Capability Registration**:
+  - `LIBRARIAN_CAPABILITY` definition with research domains
+  - Automatic registration on application startup
+  - Integration with Household Registry
+
+- **Configuration**:
+  - `LIBRARY_DESK_HOST`: Library-desk API URL (default: `http://localhost:8089`)
+  - `LIBRARY_DESK_API_KEY`: Optional API key for authentication
+  - `LIBRARY_DESK_TIMEOUT`: Request timeout in seconds (default: 60)
+
+- **Test Suite**:
+  - 78 new tests for Phase 3 components
+  - Protocol model tests (requests, responses, intents, errors)
+  - Coordination engine tests (delegation, streaming, multi-agent)
+  - Library-desk client tests (all endpoints with mocked HTTP)
+  - Wiki write operation tests (update, smart-create)
+  - Capability registration tests
+
+### Changed
+- Application startup now registers The Librarian with Household Registry
+- Configuration expanded to support library-desk API integration
+- **Version loading**: APP_VERSION now dynamically loaded from pyproject.toml
