Struct Role 

pub struct Role {
    pub system_prompt: Option<String>,
    pub system_prompt_file: Option<String>,
}

A reusable role definition that can be referenced by steps.

Roles define system prompts that shape agent behavior. Each role can provide its prompt inline or load it from an external file, enabling maintainable workflows with many distinct personas.

Fields

system_prompt: Option<String>

Inline system prompt for this role. Supports ${var} references.

system_prompt_file: Option<String>

Path to a file containing the system prompt (relative to the .zug file). Loaded at execution time. Supports ${var} references in the file content.
