priority: Option<NotificationPriority>,
metadata: HashMap<String, String>,
},
}
```

### ✅ 4. Update ActionSpec to use NotificationSpec
**Location**: `src/dsl/schema.rs:501-530`
**Before**:
```rust
pub struct ActionSpec {
pub notify: Option<String>, // Simple string
}
```
**After**:
```rust
pub struct ActionSpec {
/// Notification specification (supports both simple string and full NotificationSpec)
///
/// # Examples
/// [... comprehensive examples ...]
#[serde(default, skip_serializing_if = "Option::is_none")]
pub notify: Option<NotificationSpec>,
}
```
**Status**: ✅ IMPLEMENTED
- Type changed from String to NotificationSpec
- Comprehensive documentation added
- Backward compatible via untagged enum
### ✅ 5. Add workflow-level notification defaults to DSLWorkflow
**Location**: `src/dsl/schema.rs:62-63` and `1437-1433`
**DSLWorkflow Addition**:
```rust
pub struct DSLWorkflow {
// ... existing fields ...
/// Default notification settings for the workflow
#[serde(default, skip_serializing_if = "Option::is_none")]
pub notifications: Option<NotificationDefaults>,
}
```
**NotificationDefaults Struct**:
```rust
pub struct NotificationDefaults {
pub default_channels: Vec<NotificationChannel>,
pub notify_on_completion: bool,
pub notify_on_failure: bool,
pub notify_on_start: bool,
pub notify_on_workflow_completion: bool,
}
```
**Status**: ✅ IMPLEMENTED
- Field added to DSLWorkflow
- NotificationDefaults struct fully defined
- All fields with proper defaults
### ✅ 6. Ensure proper serde annotations
**Checklist**:
- ✅ All structs have `#[derive(Debug, Clone, Serialize, Deserialize)]`
- ✅ NotificationChannel uses `#[serde(tag = "type", rename_all = "snake_case")]`
- ✅ NotificationSpec uses `#[serde(untagged)]` for polymorphism
- ✅ Optional fields use `#[serde(default, skip_serializing_if = "Option::is_none")]`
- ✅ Vec fields use `#[serde(default, skip_serializing_if = "Vec::is_empty")]`
- ✅ HashMap fields use `#[serde(default, skip_serializing_if = "HashMap::is_empty")]`
- ✅ Default functions properly referenced (e.g., `default = "default_true"`)
- ✅ Skip predicates properly defined (e.g., `skip_serializing_if = "is_false"`)
**Status**: ✅ COMPLETE
- All serde annotations correct
- Follows Rust serde best practices
- Proper serialization/deserialization
