# List of Agent Add-ons

# Guardrails - Toxicity Detection

What it does: This add-on enables advanced content filters to identify and mitigate toxic, harmful, or inappropriate content. It actively screens both user inputs and agent-generated responses.
Consideration: Overly lenient settings may allow harmful or biased content; configure filters carefully to uphold safety and respect.

# Conversation Starters

Provides an initial set of suggested questions or topics to help the user begin an interaction with the Digital Expert, guiding them toward relevant areas of inquiry and reducing the effort needed to formulate a first request.

# Follow up questions

Suggests up to three relevant follow‑up questions after a user query to guide deeper engagement and exploration.

Example in Purple Fabric: After a user asks "Show me last quarter's sales performance," the agent might suggest:

"Would you like a breakdown by region?"
"Do you want to compare with the previous year?"
"Shall I highlight the top‑performing products?"

# Traces

Lets you see the detailed steps the agent took to arrive at its answer, shown directly in the response.

Note: This only controls whether the trace steps are visible to you. Purple Fabric always keeps a full, permanent record ofevery action for audit and compliance, even if traces are not shown.
