pyrit.models.SeedAttackGroup

class SeedAttackGroup(*, seeds: Sequence[Seed | Dict[str, Any]])

Bases: SeedGroup

A group of seeds for use in attack scenarios.

This class extends SeedGroup with attack-specific validation: - Requires exactly one SeedObjective (not optional like in SeedGroup)

All other functionality (simulated conversation, prepended conversation, next_message, etc.) is inherited from SeedGroup.

__init__(*, seeds: Sequence[Seed | Dict[str, Any]])

Initialize a SeedAttackGroup.

Parameters:

seeds – Sequence of seeds. Must include exactly one SeedObjective.

Raises:

• ValueError – If seeds is empty.

• ValueError – If exactly one objective is not provided.

Methods

__init__(*, seeds)	Initialize a SeedAttackGroup.
from_yaml_file(file)	Create a new object from a YAML file.
is_single_part_single_text_request()	Check if this is a single text prompt.
is_single_request()	Check if all prompts are in a single sequence.
is_single_turn()	Check if this is a single-turn group (single request without objective).
render_template_value(**kwargs)	Renders seed values as templates with provided parameters.
validate()	Validate the seed attack group state.

Attributes

harm_categories	Returns a deduplicated list of all harm categories from all seeds.
has_simulated_conversation	Check if this group uses simulated conversation generation.
next_message	Returns a Message containing only the last turn's prompts if it's a user message.
objective	Get the objective for this attack group.
prepended_conversation	Returns Messages that should be prepended as conversation history.
prompts	Get all SeedPrompt instances from this group.
simulated_conversation_config	Get the simulated conversation configuration if set.
user_messages	Returns all prompts as user Messages, one per sequence.
seeds

property objective: SeedObjective

Get the objective for this attack group.

Unlike SeedGroup.objective which may return None, SeedAttackGroup guarantees exactly one objective exists.

Returns:

The SeedObjective for this attack group.

seeds: List[Seed]

validate() → None

Validate the seed attack group state.

Extends SeedGroup validation to require exactly one objective.

Raises:

ValueError – If validation fails.
