The Combine Hooks \[2] node merges two hook groups into a single combined hook group. It takes two optional hook inputs and combines them using ComfyUI's hook combination functionality. This allows you to consolidate multiple hook configurations for streamlined processing.

## Inputs

| Parameter | Data Type | Input Type | Default | Range | Description                  |
| --------- | --------- | ---------- | ------- | ----- | ---------------------------- |
| `hooks_A` | HOOKS     | Optional   | None    | -     | First hook group to combine  |
| `hooks_B` | HOOKS     | Optional   | None    | -     | Second hook group to combine |

**Note:** Both inputs are optional, but at least one hook group must be provided for the node to function. If only one hook group is provided, it will be returned unchanged.

## Outputs

| Output Name | Data Type | Description                                                     |
| ----------- | --------- | --------------------------------------------------------------- |
| `hooks`     | HOOKS     | Combined hook group containing all hooks from both input groups |
