Returns the catalog of available step types for v2 test actions (ETH_WEB_SCRIPT_V2, SMARTPHONE_APP_SCRIPT_V2).

<Note>
  **Read-only.** Safe to call: this tool does not modify data.
</Note>

## Parameters

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `detail` | boolean | No | If true, return full JSON with input schemas. Default: compact one-liner format. |
| `platform` | string (web \| smartphone) | No | Filter by platform: web, smartphone, or omit for all |

## Example arguments

Illustrative arguments an agent supplies when calling this tool:

```json
{
  "detail": false,
  "platform": "web"
}
```

## Description

```text
Each step type has a versioned identifier (e.g. "click/v1.0.0"), platform compatibility, and whether it requires a locator. Use this to discover what steps can be added to a v2 no-code test. For classic test types (SIM, ETH non-web), use list_action_types instead.
