Inspector **Settings**. Empty-field rules for the Graph: [Previous nodes](/graph/previous-nodes). **Insert value** is on **Query**.

On an Agent Tool, both fields can be **Agent decides** or **Fixed**.

| Field     | Required | Empty        | Notes                                                                                                     |
| --------- | -------- | ------------ | --------------------------------------------------------------------------------------------------------- |
| **Query** | No       | —            | Empty uses the Run / Chat prompt, not previous Result. Placeholder `{{input}}` is Test input / Run input. |
| **Limit** | No       | Default: `5` | 1–20.                                                                                                     |
