        message: String,
    },
    Approve {

}

The type of signal being sent.

Variants

Kind	Scope	Effect
Veto	Global only	Stop all operations
Cancel	Channel	Stop operations in channel
Pause	Channel/Component	Pause operations
Resume	Channel/Component	Resume paused operations
Steer	Channel	Modify direction with message
Approve	Component	Approve pending HIL request
Reject	Component	Reject pending HIL request
Modify	Component	Approve with modifications

Variants

Veto

Global stop - requires elevated privilege.

Stops all operations across all channels. This is the “emergency stop” for the entire system.

Cancel

Cancel operations in a specific scope.

Stops operations in the targeted channel(s).

Pause

Pause operations in a specific scope.

Paused operations can be resumed with Resume.

Resume

Resume paused operations.

Resumes operations that were paused with Pause.

Steer

Modify direction with a message.

Allows Human to steer the execution without stopping.

Fields

message: String

Instruction for how to change direction.

Approve

Approve a pending HIL request.

Sent by Human to approve an operation that requires approval.

Fields

approval_id: String

ID of the approval request to approve.

Reject

Reject a pending HIL request.

Sent by Human to reject an operation that requires approval.

Fields

approval_id: String

ID of the approval request to reject.

reason: Option<String>

Optional reason for rejection.

Modify

Approve with modifications.

Sent by Human to approve an operation with modified parameters. This allows Human to adjust the proposed action before execution.

Example Use Cases

• Modify file path before write
• Adjust command arguments before execution
• Change scope of operation

Fields

approval_id: String

ID of the approval request to modify.

modified_payload: Value

Modified payload to use instead of original.
