## New Capabilities Documented

### 1. Agentic Orchestration Layer
- **Command**: `abi-core add agentic-orchestration-layer`
- **Components**: Planner Agent + Orchestrator Agent
- **Prerequisites**: Guardian + Semantic Layer
- **Ports**: Planner (11437), Orchestrator (8002 A2A, 8083 Web)

### 2. Planner Agent
- Task decomposition with Chain of Thought
- Semantic agent discovery via MCP tools
- Clarification question generation
- Dependency management
- Execution strategy selection

### 3. Orchestrator Agent
- Workflow execution with LangGraph
- Agent health monitoring with retries
- Progress streaming (every 5 seconds)
- Result synthesis with LLM
- Q&A handling between agents
- Web interface (HTTP/SSE)

### 4. Signed Agent Cards
- Generated at build time
- HMAC-SHA256 authentication
- Unique `shared_secret` per agent (32-byte token)
- Immutable and persistent
- Automatic registration with semantic layer
- No runtime initialization needed

### 5. Multi-Agent Workflows
