Operation

start_policy_generation async

start_policy_generation(input: StartPolicyGenerationInput, plugins: list[Plugin] | None = None) -> StartPolicyGenerationOutput

Initiates the AI-powered generation of Cedar policies from natural language descriptions within the AgentCore Policy system. This feature enables both technical and non-technical users to create policies by describing their authorization requirements in plain English, which is then automatically translated into formal Cedar policy statements. The generation process analyzes the natural language input along with the Gateway's tool context to produce validated policy options. Generated policy assets are automatically deleted after 7 days, so you should review and create policies from the generated assets within this timeframe. Once created, policies are permanent and not subject to this expiration. Generated policies should be reviewed and tested in log-only mode before deploying to production. Use this when you want to describe policy intent naturally rather than learning Cedar syntax, though generated policies may require refinement for complex scenarios.

Parameters:

Name	Type	Description	Default
input	StartPolicyGenerationInput	An instance of StartPolicyGenerationInput.	required
plugins	list[Plugin] | None	A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.	None

Returns:

Type	Description
StartPolicyGenerationOutput	An instance of StartPolicyGenerationOutput.

Input

StartPolicyGenerationInput dataclass

Dataclass for StartPolicyGenerationInput structure.

Attributes

client_token class-attribute instance-attribute

client_token: str | None = None

A unique, case-sensitive identifier to ensure the idempotency of the request. The AWS SDK automatically generates this token, so you don't need to provide it in most cases. If you retry a request with the same client token, the service returns the same response without starting a duplicate generation.

content class-attribute instance-attribute

content: Content | None = None

The natural language description of the desired policy behavior. This content is processed by AI to generate corresponding Cedar policy statements that match the described intent.

name class-attribute instance-attribute

name: str | None = None

A customer-assigned name for the policy generation request. This helps track and identify generation operations, especially when running multiple generations simultaneously.

policy_engine_id class-attribute instance-attribute

policy_engine_id: str | None = None

The identifier of the policy engine that provides the context for policy generation. This engine's schema and tool context are used to ensure generated policies are valid and applicable.

resource class-attribute instance-attribute

resource: Resource | None = None

The resource information that provides context for policy generation. This helps the AI understand the target resources and generate appropriate access control rules.

Output

StartPolicyGenerationOutput dataclass

Dataclass for StartPolicyGenerationOutput structure.

Attributes

created_at instance-attribute

created_at: datetime

The timestamp when the policy generation request was created.

findings class-attribute instance-attribute

findings: str | None = None

Initial findings from the policy generation process.

name instance-attribute

name: str

The customer-assigned name for the policy generation request.

policy_engine_id instance-attribute

policy_engine_id: str

The identifier of the policy engine associated with the started policy generation.

policy_generation_arn instance-attribute

policy_generation_arn: str

The ARN of the created policy generation request.

policy_generation_id instance-attribute

policy_generation_id: str

The unique identifier assigned to the policy generation request for tracking progress.

resource instance-attribute

resource: Resource

The resource information associated with the policy generation request.

status instance-attribute

status: PolicyGenerationStatus

The initial status of the policy generation request.

status_reasons instance-attribute

status_reasons: list[str]

Additional information about the generation status.

updated_at instance-attribute

updated_at: datetime

The timestamp when the policy generation was last updated.
