## Run this action

This action has conditional or dynamic inputs. A static example cannot describe these inputs reliably.

Read the live contract before you execute this action:

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline describe smartlead_add_tag_to_lead --json
```

## Example response

The static output schema lacks the details for a reliable example. Use `deepline describe smartlead_add_tag_to_lead --json` for the complete live contract.

## Input reference
