AI BriefingHow to Design Agents for Production Environments
Key point
The Rubric Labs team details the technical architecture and logic of deploying the Cal.ai scheduling agent to production using LangChain.
Details
The Rubric Labs team developed Cal.ai, an AI-powered email assistant for Cal.com, to simplify the complexity of calendar management. The system aims to be a personal scheduling assistant that converts informal emails like "Let's meet at 2 PM tomorrow" into appointments and performs natural language-based CRUD operations, such as rescheduling appointments or answering basic questions.
For production deployment, they adopted LangChain's OpenAI functions agent. This choice was suitable for handling structured data because the Cal.com API exposes scheduling tasks with clear inputs. A core component of the architecture is the use of memory in the form of a scratchpad, where the AI writes its own notes.
In the input stage, emails sent by users to [email protected] are parsed by MailParser, and the sender's address is verified via DKIM records to prevent spoofing. Additionally, after an extra check confirms that the email originates from a Cal.com user, the validated data is passed to the agent loop.
