-#### Agent Reference Formatting

-- **Store agents**: Use full Docker image reference with tag (e.g., `user/agent:latest`)
-- **Explicit agent_ref field**: MCP responses include unambiguous agent reference for tool calls

 ### Session Commands During CLI Usage

 - `/reset` - Clear session history
-- `/eval <expression>` - Evaluate expression (debug mode)
+- `/usage` - Show token usage statistics
+- `/compact` - Generate summary and compact session history
+- `/eval` - Save evaluation data
 
 ## File Locations and Patterns

 ### Configuration File Locations

 ### Environment Variables

 ## Debugging and Troubleshooting
 
 ### Debug Mode
 
 - Add `--debug` flag to any command for detailed logging
+- Logs written to `~/.cagent/cagent.debug.log` by default
+- Use `--log-file <path>` to specify custom log location
 - Example: `./bin/cagent run config.yaml --debug`
 
+### OpenTelemetry Tracing
+
+- Add `--otel` flag to enable OpenTelemetry tracing
+- Example: `./bin/cagent run config.yaml --otel`
+
 ### Common Issues
 
 - **Agent not found**: Check agent name matches config file agent definitions
 - **Tool startup failures**: Verify MCP tool commands and dependencies are available
-- **Multi-tenant sessions**: Remember all MCP clients currently share sessions
+- **Model not found**: Ensure model is defined in config or use inline format (provider/model)
