**The Nutlope/hallmark repository does not ship with an automated test suite, so you cannot execute `npm test` or `yarn test`; instead, you must verify functionality using the built-in `hallmark audit` command and manual file validation.**

The Hallmark repository is a design-skill package created by Nutlope that helps identify and fix UI anti-patterns in AI coding environments. Because it functions as a skill for Claude Code, Cursor, or Codex rather than a traditional library, the repository contains no unit tests, integration tests, or a `test` script in its [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json). If you need to confirm that the code operates correctly, you must rely on manual verification steps and the skill's own validation logic.

## Why There Is No `npm test` Command

Unlike conventional Node.js projects, the Hallmark repository contains no test files such as `*.test.js`, `*.spec.js`, or a `tests/` directory. Additionally, the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) file does not define a `test` script. According to the source code structure, this is intentional because Hallmark is designed to be consumed as a skill via `npx skills add` rather than as a dependency with a traditional test harness.

## Manual Verification Methods

Since automated tests are absent, use the following three-step process to validate the installation and functionality.

### Install the Skill

The primary method for obtaining Hallmark is through the Skills CLI. Run the installation command described in the [`README.md`](https://github.com/Nutlope/hallmark/blob/main/README.md):

```bash
npx skills add nutlope/hallmark

```

This pulls the skill into Claude Code, Cursor, Codex, or compatible environments.

### Verify Core Files

After installation, confirm that the essential skill files are present in your environment:

- [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) — Contains the rule-set that drives the skill's behavior.
- `skills/hallmark/references/` — Directory holding design reference documents used for pattern matching.

### Run the Built-in Audit Command

The skill provides a functional validation mechanism through its audit command. This evaluates a target page against Hallmark's anti-patterns and serves as the closest equivalent to a smoke test:

```bash
hallmark audit <target-url-or-path>

```

For example, to test against the Hallmark demo site:

```bash
hallmark audit https://www.usehallmark.com/examples/hum-07/

```

## Complete Validation Workflow

If you clone the repository to inspect or modify the source, follow this workflow to ensure everything functions correctly:

```bash

# 1. Clone the repository

git clone https://github.com/Nutlope/hallmark.git
cd hallmark

# 2. Install dependencies (only required for local modifications)

npm install

# 3. Execute the skill's audit command to validate functionality

npx hallmark audit https://www.usehallmark.com/examples/hum-07/

```

## Key Files and Their Roles

Understanding the repository structure helps you verify that all components are present:

- **[`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md)** — The core rule-set defining the skill's logic and anti-pattern detection rules.
- **`skills/hallmark/references/`** — Collection of design reference documents that the skill uses to evaluate UI implementations.
- **[`docs/recipes.md`](https://github.com/Nutlope/hallmark/blob/main/docs/recipes.md)** — Contains example usage recipes demonstrating how to invoke the skill in various scenarios.
- **[`README.md`](https://github.com/Nutlope/hallmark/blob/main/README.md)** — Provides installation instructions and links to the live demo.

## Summary

- The Nutlope/hallmark repository contains no automated test suite, `*.test.js` files, or `test` script in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json).
- **Install the skill** using `npx skills add nutlope/hallmark` for Claude Code, Cursor, or Codex environments.
- **Validate manually** by checking for [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) and the `references/` directory.
- **Run the audit command** (`hallmark audit <url>`) as the built-in functional test to verify the skill operates correctly.

## Frequently Asked Questions

### Does Hallmark have unit tests?

No, the repository does not include unit tests. The project is a design-skill package intended for AI coding assistants, and the source tree contains no `*.test.js`, `*.spec.js`, or `tests/` directory. Validation relies on the `hallmark audit` command and manual file verification.

### What is the hallmark audit command?

The `hallmark audit` command is a built-in CLI function that evaluates a target URL or local file path against Hallmark's design anti-patterns. It acts as a functional smoke test, executing the skill's validation logic to ensure the rule-set in [`SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/SKILL.md) processes input correctly.

### Where are the test files in the repository?

There are no test files in the Nutlope/hallmark repository. The project structure excludes conventional testing directories, and the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) does not contain a `test` script, reflecting its architecture as an installable skill rather than a test-driven library.

### How do I know if Hallmark is installed correctly?

Verify installation by confirming the presence of [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) and the `skills/hallmark/references/` directory in your environment. Then run `hallmark audit` against a known URL; if it executes without errors and returns design feedback, the skill is functioning properly.
