Overview

Lemon Agent is an unmaintained open-source project for planning and executing workflows through configured application tools.

Lemon Agent is an unmaintained open-source project for planning and executing workflows through configured application tools.

A planner and solver turn a request into tool calls, and reusable JSON workflows can describe repeated tasks. Permission requests depend on the agent following the workflow instruction; they are not a substitute for access controls.

The original repository explicitly says it is no longer actively maintained. Setup requires Node, pnpm, model credentials and the selected services’ credentials.

MIT source is free to obtain, but model use, service accounts, hosting and developer maintenance are not included.

The implemented tool catalog includes Airtable, Slack, HubSpot, GitHub, Notion, Discord, Medium, Monday.com and Hacker News. Gmail, Calendar, Stripe and Salesforce are roadmap items in this repository, not shipped connectors.

Use Lemon Agent as a developer reference or supervised experiment. Budget for dependency maintenance and carefully limit the accounts and actions it can access.

Autonomy level

70/100

Our subjective rating of how independently the product carries out its documented tasks, considering the human setup, input, approval and review it needs. This is not a measured success rate.

Reasoning: Lemon Agent plans and executes configured tool calls and reusable workflows. Developers supply goals, tools and credentials, supervise permissions and costs and inspect the results. The score describes the original unmaintained project’s workflow; instruction-based approval prompts do not replace service access controls.
