# RouteLoad

one tool a route calls when it opens: the tool, its inputs from the route's params, and the slot its response card fills

[figure: RouteLoad is a value at none scope. The drawing shows its fields and the objects that they point at.]

| property | value |
|---|---|
| kind | value |
| scope | none |
| key | none |
| store | none |
| family | interfaces |



## Fields


| field | type | required | note |
|---|---|---|---|
| `tool` | `text` | yes | a tool id of the register |
| `inputs` | `json` | yes | from the route's params and search parameters |
| `fills` | `text` | yes | a slot name |



## Routes that use it
No route takes or returns RouteLoad directly. The record holds it, and the objects that point at it reach it.
