+//! Workflow orchestration module
+//!
+//! This module provides workflow execution, orchestration, parsing, validation,
+//! and template rendering capabilities for the Attune workflow orchestration system.
+//!
+//! # Modules
+//!
+//! - `parser`: Parse YAML workflow definitions into structured types
+//! - `graph`: Build executable task graphs from workflow definitions
+//! - `context`: Manage workflow execution context and variables
+//! - `task_executor`: Execute individual workflow tasks
+//! - `coordinator`: Orchestrate workflow execution with state management
+//! - `template`: Template engine for variable interpolation (Jinja2-like syntax)
+//!
+//! # Example
+//!
+//! ```no_run
+//! use attune_executor::workflow::{parse_workflow_yaml, WorkflowCoordinator};
+//!
+//! // Parse a workflow YAML file
+//! let yaml = r#"
+//! ref: my_pack.my_workflow
+//! label: My Workflow
+//! version: 1.0.0
+//! tasks:
+//!   - name: hello
+//!     action: core.echo
+//!     input:
+//!       message: "{{ parameters.name }}"
+//! "#;
+//!
+//! let workflow = parse_workflow_yaml(yaml).expect("Failed to parse workflow");
+//! ```
