Overview
A meta-agent routes queries to specialized assistants, incorporating safety checks and production trajectory evaluation.
Workflow
Lyft implemented a customer service agent platform using LangGraph and LangSmith. A meta-agent routes incoming queries to specialized sub-agents, which are either hand-built or generated from JSON configurations. The system incorporates safety checks on every interaction turn and uses LLM judges to review sampled production traces. Human oversight is implied through the routing logic and safety protocols, though specific manual review steps are not detailed in the source.
Reported result
The source reports that building a new support agent was reduced from approximately 6 months to 2 weeks. Additionally, the AI resolution rate increased by 16%. These metrics are attributed to the implementation of the meta-agent routing system and associated safety/evaluation protocols. No independent verification of these figures is provided in the text.

The effectiveness of the safety checks and LLM judges is asserted but not quantified beyond the resolution rate.

Try it
Act as an AI agent architect. I need to design a pilot for a customer support routing system similar to Lyft's. Inputs: - [replaceable: Sample customer queries JSON file] - [replaceable: List of specialized support topics (e.g., refunds, account access)] - [replaceable: Target platform (e.g., LangGraph, custom Python)] Steps: 1. Define a meta-agent prompt that classifies incoming queries into the provided topics. 2. Create stub sub-agents for each topic with basic response templates. 3. Implement a safety check function that flags queries containing sensitive keywords (e.g., 'password', 'credit card'). 4. Set up a logging mechanism to record routing decisions and safety flags. 5. Run a dry run on 10 sample queries. Output a table showing: Query ID, Routed Agent, Safety Flag Status, and Confidence Score. 6. Ask me to review the dry run results before proceeding to any real integration or deployment. Deliverables: - Python code for the meta-agent and stubs. - A CSV report of the dry run. - A brief explanation of how the safety checks work. Constraints: - Do not connect to any live customer data. - Use mock data for the dry run. - Ensure the code is modular so sub-agents can be swapped later.
