# Role Adherence

> Checks whether your chatbot stays within its defined role across the entire conversation.

The **Role Adherence** metric is one of several [non-deterministic Metric](/concepts/metric) Galtea uses to evaluate whether your LLM-based chatbot maintains consistency with its assigned role throughout a conversation. This role could be defined by system prompts (e.g., "you are a travel assistant") or contextual constraints (e.g., tone, domain, responsibilities).

This is especially important in enterprise and safety-sensitive applications, where the chatbot must not deviate from its designated behavior or scope.

## Evaluation Parameters

To compute the `role_adherence` metric, the following inputs are required in every turn of the conversation:

* **`input`**: The current user message.
* **`actual_output`**: The corresponding chatbot response.

This metric will evaluate the whole conversation, including all turns, to evaluate consistency with the assigned role over time.

## How Is It Calculated?

The `role_adherence` score is computed using an LLM-as-a-judge approach:

1. **Define the Persona**: Based on the `product_description`, the LLM identifies the expected persona, tone, professional boundaries, and style.
2. **Audit the Conversation**: The LLM reviews every response from the agent in the conversation history.
3. **Check for Deviations**: The LLM evaluates whether the agent broke character, violated tone constraints, strayed from its designated responsibilities, or suddenly deviated from the inferred role.

The metric assigns a **binary score**:

* **Score 1.0 (Adherent):** The agent consistently maintained its role, tone, and persona throughout all turns.
* **Score 0.0 (Non-Adherent):** The agent deviated from its role, broke character, or adopted an inconsistent tone at any point.

## Suggested Test Case Types

The Role Adherence metric is effective for evaluating Behavior test cases in Galtea, particularly:

* **Persona-driven conversations** where the agent has a defined character or role.
* **Adversarial prompts** that attempt to make the agent break character.
* **Enterprise scenarios** where consistent professional tone and scope adherence are required.
