Openmelon

Openmelon is a terminal-based content-creation agent that uses an LLM and tools to draft within project context. Projects keep character records, reference images and generated artifacts on disk, and the agent can use reference images as anchors when generating images.

Understand the project

Practical overview

When it fits

Use it for terminal-based creative production when project-specific characters, reference images or prior creative decisions should inform drafting or image generation.

Who it is for

  • Creators producing content across recurring projects or characters.
  • Writers and visual creators who want an agent to draw on project references while drafting.
  • Technical users comfortable configuring an API key and working in a terminal.

Documented uses

  • Draft content using a Skillplus package and project context.
  • Look up character records and reference images while working on a prompt.
  • Generate an image with optional project reference images.
  • Keep session transcripts and generated artifacts organized within a project.
  • Resume a prior session with its conversation as context.
Before you choose

Requirements & limits

The documented setup requires an API key from OpenRouter, OpenAI or Anthropic. An image model can be configured or skipped.

  • Openmelon is a CLI workflow rather than a documented hosted editor.
  • First-run setup asks users to trust the working directory and configure an LLM provider and model.
  • Shell tool permissions default to strict approval.
  • The Apache-2.0-licensed repository is written in Go; the documented npm installation downloads a matching Go binary.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Openmelon and initialize a project

Install the documented packages, then use first-run setup to configure the agent and project.

Before you start

  • Node.js package installation support for the documented npm packages
  • An API key from OpenRouter, OpenAI or Anthropic
  • A project working directory

Steps

  1. Install the packages with the command below.

    Documented command
    npm install -g @e8s/openmelon @e8s/skillplus

  2. Change to the intended project directory and run openmelon.

  3. Follow first-run setup to confirm directory trust, enter an API key, choose an LLM model, optionally configure an image model, and initialize the project.

Expected outcome

The working directory is initialized with Openmelon's project configuration and the terminal interface is ready for a content session.

Guide limitations

  • An image model may be skipped during setup.
  • The README documents API-key configuration but does not specify provider pricing or account terms.
