+
+## Change ID
+`add-as-priority-scale-in-unhealthy`
+
+## Status
+✅ **IMPLEMENTED** (10/11 tasks completed)
+
+## Implementation Date
+2025-12-10
+
+## Overview
+Successfully added support for the `priority_scale_in_unhealthy` parameter to the `tencentcloud_as_scaling_group` resource. This parameter controls whether unhealthy instances should be prioritized during scale-in operations in TencentCloud Auto Scaling.
+
+## Changes Made
+
+### 1. Schema Definition ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group.go`
+- Added `priority_scale_in_unhealthy` field at line 188-192
+- Type: `schema.TypeBool`
+- Optional: true
+- Description: "Whether to enable priority for unhealthy instances during scale-in operations. If set to `true`, unhealthy instances will be removed first when scaling in."
+
+### 2. Create Operation ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group.go`
+- Added field retrieval at line 339: `priorityScaleInUnhealthy = d.Get("priority_scale_in_unhealthy").(bool)`
+- Updated condition check at line 342 to include the new field
+- Added to `ServiceSettings` struct at line 357: `PriorityScaleInUnhealthy: &priorityScaleInUnhealthy`
+
+### 3. Read Operation ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group.go`
+- Added `d.Set` call at lines 496-498 to read the parameter value from state
+- Follows the same pattern as other ServiceSettings fields
+
+### 4. Update Operation ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group.go`
+- Added change detection at line 626: `d.HasChange("priority_scale_in_unhealthy")`
+- Updated `updateAttrs` slice at line 627 to include the new field
+- Added field retrieval at line 639: `priorityScaleInUnhealthy := d.Get("priority_scale_in_unhealthy").(bool)`
+- Added to `ServiceSettings` struct at line 646: `PriorityScaleInUnhealthy: &priorityScaleInUnhealthy`
+
+### 5. Testing ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group_test.go`
+- Added test assertion at line 145: `resource.TestCheckResourceAttr(..., "priority_scale_in_unhealthy", "true")`
+- Added test configuration at line 281: `priority_scale_in_unhealthy = true`
+
+### 6. Documentation ✅
+**File**: `tencentcloud/services/as/resource_tc_as_scaling_group.md`
+- Added parameter to complete example at line 97: `priority_scale_in_unhealthy = true`
+- Documentation will be auto-generated from schema description via `make doc`
+
+### 7. Code Quality ✅
+- Code formatting applied with `gofmt`
+- No new linting errors introduced
+- Code compiles successfully
+- Follows existing patterns and conventions
+
+## Files Modified
+
+| File | Lines Changed | Description |
+|------|---------------|-------------|
+| `tencentcloud/services/as/resource_tc_as_scaling_group.go` | ~20 additions | Added schema, create, read, update logic |
+| `tencentcloud/services/as/resource_tc_as_scaling_group_test.go` | 2 additions | Added test assertions and config |
+| `tencentcloud/services/as/resource_tc_as_scaling_group.md` | 1 addition | Added example usage |
+| `openspec/changes/add-as-priority-scale-in-unhealthy/tasks.md` | Updated | Marked tasks as completed |
+
+## Testing Status
+
+### Automated Testing ✅
+- **Unit Tests**: N/A (Provider uses acceptance tests)
+- **Compilation**: ✅ Code compiles without errors
+- **Linting**: ✅ No new linting errors introduced
+- **Formatting**: ✅ Code properly formatted with gofmt
+
+### Manual Testing ⏳
+- **Status**: Pending (requires TencentCloud environment access)
+- **Required Actions**:
+  1. Create a scaling group with `priority_scale_in_unhealthy = true`
+  2. Verify setting is applied in TencentCloud console
+  3. Update parameter to `false` and verify change
+  4. Test import functionality
+
+## API Mapping
+
+| Terraform Field | API Field | Location |
+|----------------|-----------|----------|
+| `priority_scale_in_unhealthy` | `ServiceSettings.PriorityScaleInUnhealthy` | Create/Modify/Describe AutoScalingGroup |
+
+## Compatibility
+
+### Backward Compatibility ✅
+- **Breaking Changes**: None
+- **Default Behavior**: Unchanged (field is optional)
+- **State Migration**: Not required
+- **Existing Configurations**: Continue to work without modification
+
+### API Compatibility ✅
+- **TencentCloud SDK**: Uses existing SDK version (already in vendor)
+- **API Version**: v20180419
+- **Field Support**: Confirmed in API documentation
+
+## Example Usage
+
+```hcl
+resource "tencentcloud_as_scaling_group" "example" {
+  scaling_group_name              = "example-scaling-group"
+  configuration_id                = tencentcloud_as_scaling_config.example.id
+  max_size                        = 10
+  min_size                        = 0
+  vpc_id                          = tencentcloud_vpc.example.id
+  subnet_ids                      = [tencentcloud_subnet.example.id]
+
+  # Enable priority scale-in for unhealthy instances
+  priority_scale_in_unhealthy     = true
+
+  # Other ServiceSettings parameters
+  replace_monitor_unhealthy       = true
+  scaling_mode                    = "WAKE_UP_STOPPED_SCALING"
+}
+```
+
+## Known Issues
+None
+
+## Follow-up Actions
+1. **Manual Validation** (Task 5.2): Requires access to TencentCloud environment
+   - Create test scaling group
+   - Verify parameter behavior
+   - Test update operations
+   - Validate import functionality
+
+2. **Acceptance Test Execution**: Run with TencentCloud credentials
+   ```bash
+   TF_ACC=1 go test ./tencentcloud/services/as -v -run TestAccTencentCloudAsScalingGroup
+   ```
