**Yes, Hallmark AI is fully open-source under the MIT License, allowing anyone to view, modify, and distribute the code.**

Hallmark AI is a public GitHub repository maintained by Nutlope that provides AI-powered design and theming capabilities for web projects. Because the entire codebase is hosted publicly and licensed under permissive terms, developers can inspect the implementation, contribute improvements, and integrate the tool into their own workflows without restriction.

## Verifying Open-Source Status

The open-source nature of Hallmark AI is established through its licensing and repository visibility. According to the source code in `Nutlope/hallmark`, the project meets all criteria for open-source software distribution.

### MIT License Permissions

The repository includes a `LICENSE` file at the root level that explicitly applies the **MIT License** to the codebase. This license permits users to:

- Copy, modify, merge, and distribute the source code
- Use the software for commercial or private projects
- Include the code in proprietary applications, provided the license and copyright notice are preserved

Unlike copyleft licenses, the MIT License imposes minimal restrictions, making Hallmark AI suitable for both personal experimentation and enterprise adoption.

### Public Repository Structure

The [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) file confirms the project’s distributable status by declaring npm package metadata and dependencies. This file serves as the canonical reference for the project’s entry points and versioning. Additionally, the [`README.md`](https://github.com/Nutlope/hallmark/blob/main/README.md) provides public installation instructions that assume a reusable, community-accessible codebase, further confirming the open-source intent.

## Key Source Files and Architecture

Understanding the codebase structure helps verify its open-source accessibility. The repository organizes functionality across distinct directories with clear separation of concerns.

### Configuration and Metadata

- **`LICENSE`** – Contains the full MIT License text that governs usage rights
- **[`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json)** – Declares the skill’s npm configuration and CLI entry points
- **[`README.md`](https://github.com/Nutlope/hallmark/blob/main/README.md)** – Documents installation procedures and feature overviews
- **[`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md)** – Defines the formal skill interface for AI assistant integration

### Core Implementation

The interactive functionality resides in client-side JavaScript. The [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js) file implements core features including the **`applyTheme`** function, which handles dynamic theme switching. The repository also includes [`site/index.html`](https://github.com/Nutlope/hallmark/blob/main/site/index.html), a working demonstration page that showcases the skill’s output capabilities and serves as a reference implementation for developers.

## Installing and Using Hallmark AI

Because Hallmark AI is open-source, you can install it via standard npm workflows or invoke it directly without purchasing proprietary licenses.

### Install via npx

Add the Hallmark skill to your environment using the command documented in the README:

```bash
npx skills add nutlope/hallmark

```

### Command-Line Interface

The package exposes a CLI tool for generating designs. Invoke the `hallmark` command to process specific files with mood parameters:

```bash
hallmark redesign ./src/pages/home.html --mood modern-minimal

```

### Programmatic Theme Application

For embedded usage, call the client-side `applyTheme` function defined in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js):

```javascript
// Switch to the cobalt color theme
applyTheme('cobalt');

```
