Parlant

What it does

Parlant is a conversational governance framework designed to move AI agent behavior from brittle system prompts to a structured engineering approach. It acts as a harness that dynamically narrows the LLM's context to only the most relevant guidelines, tools, and knowledge for each specific turn, ensuring consistency and brand alignment in high-stakes customer interactions.

Tools

• create_agent: Initializes a new agent with a name and description.
• create_observation: Defines conditions under which specific tools or guidelines should trigger.
• create_guideline: Sets behavioral rules as condition-action pairs to control agent response style and content.
• create_journey: Creates multi-turn SOPs for structured processes like onboarding or booking.
• create_canned_response: Defines pre-approved templates to eliminate hallucinations in critical responses.
