Lemon Agent is a Plan-Validate-Solve (PVS) agent designed for reliable workflow automation, enabling LLMs to interact with tools like Airtable, Notion, and GitHub. It targets developers and power users seeking to build automated workflows with LLM-driven task execution and human-in-the-loop validation.

How It Works

Lemon Agent employs a supervised Plan and Solve approach, separating task planning from execution. A Planner Agent defines the workflow, potentially seeking user approval at critical steps, and then communicates with a Solver Agent. The Solver Agent executes the workflow using a variety of integrated tools, ensuring focused agent performance and increased accuracy.
