Struct AssertDefinition 

pub struct AssertDefinition {
    pub name: String,
    pub preset: Option<String>,
    pub prompt: Option<String>,
    pub system: Option<String>,
    pub user_template: Option<String>,
    pub assert_text: Option<String>,
    pub agent: Option<String>,
    pub task_template: Option<String>,
}

Reusable assertion definition referenced by name from assert steps.

Definitions can either reference a built-in preset via preset, supply a custom LLM prompt, or define a custom preset by providing both system and user_template. Custom presets support the same template variables as built-in presets: {url}, {title}, {content}, {expected_text}, {description}.

Fields

name: String

Unique name used to reference this definition from steps.

preset: Option<String>

Predefined assertion preset name (e.g. no_error_on_page, text_visible).

prompt: Option<String>

Custom LLM prompt for assertion evaluation.

system: Option<String>

System prompt for a custom preset.

user_template: Option<String>

User template (with {placeholders}) for a custom preset.

assert_text: Option<String>

Text that the text_visible preset checks for, or the {expected_text} placeholder value for custom presets.

agent: Option<String>

Agent endpoint to call for this assertion.

task_template: Option<String>

Agent task template for this assertion.
