+
+## Agent Architecture Overview
+
+An **Agent** in CleverAgents is an autonomous entity that can perceive, reason, act, and learn.
+
+### Agent Components
+
+- **Agent State & Configuration** - Identity, goals, and configuration parameters
+- **Reasoning Engine** - LLM integration, planning, and decision-making
+- **Execution Layer** - Skill execution, tool invocation, resource management
+- **Integration Points** - Skills, tools, resources, and providers
+
+### Agent Types
+
+CleverAgents supports several agent patterns:
+
+1. **Task-Specific Agents** - Focused on a single domain or task
+2. **Orchestrator Agents** - Coordinate multiple sub-agents
+3. **Reactive Agents** - Respond to events with minimal planning
+4. **Deliberative Agents** - Perform extensive planning before execution
+
+## Agent Lifecycle
+
+The agent lifecycle consists of several key phases:
+
+1. **Created** - Agent instance instantiated
+2. **Initialized** - Configuration loaded, skills registered
+3. **Ready** - Agent prepared for execution
+4. **Executing** - Processing tasks, invoking skills
+5. **Paused** - (Optional) Suspended execution
+6. **Completed** - Task finished successfully
+7. **Cleaned Up** - Resources released
+
+### Lifecycle Hooks
+
+Agents support hooks at various lifecycle points:
+
+- `on_initialize()` - Called after initialization
+- `on_execution_start()` - Called when execution begins
+- `on_execution_end(result)` - Called when execution completes
+- `on_error(error)` - Called when an error occurs
+- `on_cleanup()` - Called during cleanup
+
+## Agent Configuration
+
+Agents are configured through a hierarchical configuration system supporting:
+
+- **Core settings** - max_iterations, timeout, temperature
+- **Model configuration** - provider, model name, API keys
+- **Skills configuration** - enabled skills and their settings
+- **Tool configuration** - available tools and their settings
+- **Resource limits** - memory, CPU, timeout constraints
+- **Safety settings** - guardrails, tool call limits, allowed domains
+
+## Skill Integration and Management
+
+**Skills** are reusable, domain-specific capabilities that agents can invoke.
+
+### Skill Structure
+
+Skills should:
+
+- Have a clear name and description
+- Define input parameters and return types
+- Implement error handling
+- Support configuration
+- Be testable in isolation
+
+### Using Skills in Agents
+
+Skills are executed through the agent:
+
+```python
+result = agent.execute_skill(
+    skill_name="document_analysis",
+    parameters={"document": content, "analysis_type": "full"}
+)
+```
+
+## Tool Integration
+
+**Tools** are external integrations that agents can invoke to interact with systems, APIs, and services.
+
+### Tool Definition
+
+Tools should:
+
+- Have clear input/output specifications
+- Implement error handling
+- Support timeout and retry logic
+- Be idempotent when possible
+- Log execution details
+
+### Using Tools in Agents
+
+Tools are executed through the agent:
+
+```python
+result = agent.execute_tool(
+    tool_name="file_reader",
+    parameters={"file_path": "/path/to/file.txt"}
+)
+```
+
+## Resource Management
+
+Agents manage various types of resources:
+
+- **Memory** - Agent state, context, and intermediate results
+- **Compute** - CPU time and processing capacity
+- **External** - API calls, database connections, file handles
+- **Time** - Execution timeouts and deadlines
+
+## Error Handling and Recovery
+
+### Error Types
+
+- **SkillExecutionError** - Skill execution failed
+- **ToolExecutionError** - Tool execution failed
+- **ResourceExhaustedError** - Resource limits exceeded
+- **TimeoutError** - Execution timeout
+- **ValidationError** - Input validation failed
+
+### Error Handling Strategies
+
+1. **Try-Catch with Recovery** - Implement retry logic with exponential backoff
+2. **Fallback Strategies** - Provide fallback goals or alternative execution paths
+3. **Graceful Degradation** - Reduce feature set or use cached results
+
+## Agent Communication Patterns
+
+### Agent-to-Agent Communication
+
+Agents can communicate through:
+
+- Message buses for asynchronous communication
+- Direct method calls for synchronous communication
+- Event systems for event-driven communication
+
+### Hierarchical Agent Communication
+
+Orchestrator agents can:
+
+- Delegate tasks to sub-agents
+- Coordinate multiple sub-agents
+- Aggregate results from sub-agents
+- Handle failures in sub-agents
+
+## Testing Agents
+
+### Unit Testing
+
+Test individual components:
+
+- Agent initialization
+- Skill execution
+- Tool execution
+- Error handling
+
+### Integration Testing
+
+Test component interactions:
+
+- Skill and tool integration
+- Agent and skill integration
+- Error recovery in integrated systems
+
+### Performance Testing
+
+Test performance characteristics:
+
+- Execution speed
+- Memory usage
+- Resource utilization
+- Scalability
+
+## Performance Optimization
+
+### Caching Strategies
+
+Implement caching to:
+
+- Avoid redundant skill executions
+- Reduce external API calls
+- Improve response times
+
+### Parallel Execution
+
+Execute multiple goals in parallel:
+
+- Use thread pools for I/O-bound operations
+- Use process pools for CPU-bound operations
+- Aggregate results from parallel executions
+
+### Lazy Loading
+
+Load resources on demand:
+
+- Lazy load skills
+- Lazy load tools
+- Lazy load models
+
+## Real-world Examples
+
+### Example 1: Document Analysis Agent
+
+Analyzes documents and generates insights:
+
+- Extracts text from documents
+- Analyzes sentiment
+- Extracts entities
+- Generates summaries
+
+### Example 2: Project Management Agent
+
+Manages projects and coordinates tasks:
+
+- Plans projects
+- Allocates resources
+- Tracks progress
+- Manages risks
+
+### Example 3: Customer Support Agent
+
+Provides customer support and issue resolution:
+
+- Classifies issues
+- Searches knowledge base
+- Generates solutions
+- Escalates when necessary
+
+## Best Practices
+
+### 1. **Design for Composability**
+- Create agents with clear, single responsibilities
+- Design skills and tools to be reusable
+- Use composition over inheritance
+
+### 2. **Implement Robust Error Handling**
+- Handle all expected error types
+- Implement recovery strategies
+- Log errors comprehensively
+
+### 3. **Manage Resources Carefully**
+- Set appropriate resource limits
+- Monitor resource usage
+- Clean up resources properly
+
+### 4. **Test Thoroughly**
+- Write unit tests for skills and tools
+- Test agent integration
+- Perform performance testing
+
+### 5. **Monitor and Observe**
+- Log agent execution
+- Track performance metrics
+- Monitor resource usage
+
+### 6. **Document Your Agents**
+- Document agent purpose and capabilities
+- Document skill and tool APIs
+- Provide usage examples
+
+## Conclusion
+
+The CleverAgents framework provides a comprehensive platform for building intelligent, autonomous agents. By following the patterns and practices outlined in this guide, you can create robust, scalable agents that effectively accomplish complex tasks.

+
+Raised when tool execution fails.
+
+```python

+        self.message = message
+```
+
+## Usage Examples
+
+### Basic Agent Usage
+
+```python
+from cleveragents.agents import Agent
+
+# Create agent
+agent = Agent(
+    name="my_agent",
+    description="My custom agent",
+    version="1.0.0"
+)
+
+# Initialize
+agent.initialize({
+    "max_iterations": 10,
+    "timeout": 300
+})
+
+# Execute
+result = agent.execute(
+    goal="Analyze the provided document",
+    context={"document": "..."}
+)
+
+# Cleanup
+agent.cleanup()
+```
+
+### With Skills and Tools
+
+```python
+# Add skills
+agent.add_skill(DocumentAnalysisSkill())
+agent.add_skill(SummarizationSkill())
+
+# Add tools
+agent.add_tool(FileReaderTool())
+agent.add_tool(DatabaseWriterTool())
+
+# Execute skill
+result = agent.execute_skill(
+    "document_analysis",
+    {"document": content}
+)
+
+# Execute tool
+result = agent.execute_tool(
+    "file_reader",
+    {"file_path": "/path/to/file.txt"}
+)
+```

+Feature: TDD Issue #10491 — TUI BINDINGS missing alt+up and alt+down block cursor navigation keys
+  As a developer
+  I want to verify that the TUI app BINDINGS include alt+up and alt+down
+  and that action_cursor_up() and action_cursor_down() methods exist and work correctly
+  So that the bug is captured and will be caught by a regression test
+
+  # These scenarios verify that the TUI app correctly handles block cursor
+  # navigation via alt+up and alt+down key bindings.  The @tdd_expected_fail
+  # tag inverts the result so CI passes while the bug is still present.
+  # When bug #10491 is fixed, the @tdd_expected_fail tag must be removed.
+
+  Background:
+    Given the TUI app module is imported with mocked Textual for cursor tests
+    And a mock command router and persona state for cursor tests
+    And the Textual TUI app is instantiated for cursor tests
+
+  @tdd_expected_fail
+  Scenario: alt+up binding is present in BINDINGS
+    Then the BINDINGS list should contain an entry for "alt+up"
+
+  @tdd_expected_fail
+  Scenario: alt+down binding is present in BINDINGS
+    Then the BINDINGS list should contain an entry for "alt+down"
+
+  @tdd_expected_fail
+  Scenario: alt+up binding maps to action_cursor_up
+    Then the BINDINGS entry for "alt+up" should map to action "cursor_up"
+
+  @tdd_expected_fail
+  Scenario: alt+down binding maps to action_cursor_down
+    Then the BINDINGS entry for "alt+down" should map to action "cursor_down"
+
+  @tdd_expected_fail
+  Scenario: action_cursor_up method exists on the TUI app
+    Then the TUI app should have an action_cursor_up method
+
+  @tdd_expected_fail
+  Scenario: action_cursor_down method exists on the TUI app
+    Then the TUI app should have an action_cursor_down method
+
+  @tdd_expected_fail
+  Scenario: pressing alt+up moves block cursor to previous conversation block
+    Given the TUI app has conversation blocks loaded
+    And the block cursor is positioned at index 2
+    When action_cursor_up is called on the TUI app
+    Then the block cursor index should be 1
+
+  @tdd_expected_fail
+  Scenario: pressing alt+down moves block cursor to next conversation block
+    Given the TUI app has conversation blocks loaded
+    And the block cursor is positioned at index 1
+    When action_cursor_down is called on the TUI app
+    Then the block cursor index should be 2
+
+  @tdd_expected_fail
+  Scenario: pressing alt+up at top of stream does not raise an error
+    Given the TUI app has conversation blocks loaded
+    And the block cursor is positioned at index 0
+    When action_cursor_up is called on the TUI app
+    Then the block cursor index should be 0
+
+  @tdd_expected_fail
+  Scenario: pressing alt+down at bottom of stream does not raise an error
+    Given the TUI app has conversation blocks loaded
+    And the block cursor is positioned at the last block
+    When action_cursor_down is called on the TUI app
+    Then the block cursor index should be at the last block

HAL9000	fdc66aa610	fix(tui): add alt+up and alt+down block cursor navigation key bindings Added a new TDD feature to validate alt+up and alt+down block cursor navigation key bindings and introduced corresponding step definitions. Also addressed several pre-existing test failures arising from multi-session support and updated app structure across multiple features and steps to align with the new multi-session workflow. - Added features/tui/block_cursor_navigation.feature to test alt+up and alt+down block cursor navigation (tagged @tdd_expected_fail since implementation isn't present yet). - Added features/steps/tui_block_cursor_navigation_steps.py for the new TDD feature steps. - Fixed pre-existing test failures related to multi-session behavior and updated structure across several tests: - features/tui_app_coverage.feature: binding count increased from 3 to 5 due to multi-session tabs (ctrl+n and ctrl+w); updated to track sessions with a _sessions list. - features/steps/tui_app_coverage_steps.py: updated steps to match the new multi-session app structure. - features/steps/tui_multi_session_tabs_steps.py: corrected step definitions (quoted parameters, plural/singular forms) and added _setup_mock_app helper. - features/steps/tui_persona_cycle_steps.py: fixed quoted parameter in the step definition. - features/steps/edge_case_plan_steps.py: added missing Pydantic validation error step. - features/steps/budget_enforcement_plan_executor_steps.py: fixed budget enforcement tests (case-insensitive message check) and added a guardrail service. - features/repl_input_modes.feature: updated to reflect new behavior (absolute paths allowed for persona export/import).
