Struct LoopDetectionConfig 

pub struct LoopDetectionConfig {
    pub threshold: u32,
    pub action: LoopAction,
}

Configuration for detecting repeated tool calls (stuck agents).

When an agent repeatedly makes the same tool call with identical arguments, it’s usually stuck in a loop. This configuration detects that pattern and takes action to break the cycle.

Example

use llm_stack::tool::{LoopDetectionConfig, LoopAction};

let config = LoopDetectionConfig {
    threshold: 3,  // Trigger after 3 consecutive identical calls
    action: LoopAction::InjectWarning,  // Tell the agent it's looping
};

Fields

threshold: u32

Number of consecutive identical tool calls before triggering.

A tool call is “identical” if it has the same name and arguments (compared via JSON equality). Default: 3.

action: LoopAction

Action to take when a loop is detected.
