One thing to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Load when a task needs complex standalone React/Tailwind/shadcn browser artifacts with state, routing, or bundled components; use effective-interact for reports and frontend-design for production UI.

The file declares its own license as Complete terms in LICENSE.txt. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Web Artifacts Builder

Harness Hub adaptation: final bundles are verified before handoff.

To build powerful frontend local browser artifacts, follow these steps:

  1. Initialize the frontend repo using scripts/init-artifact.sh
  2. Develop your artifact by editing the generated code
  3. Bundle all code into a single HTML file using scripts/bundle-artifact.sh
  4. Verify the final bundle
  5. Share the artifact with the user

Stack: React 18 + TypeScript + Vite + Parcel (bundling) + Tailwind CSS + shadcn/ui

Design & Style Guidelines

VERY IMPORTANT: To avoid what is often referred to as "AI slop", avoid using excessive centered layouts, purple gradients, uniform rounded corners, and Inter font.

Quick Start

Step 1: Initialize Project

Run the initialization script to create a new React project:

bash scripts/init-artifact.sh <project-name>
cd <project-name>

This creates a fully configured project with:

  • React + TypeScript (via Vite)
  • Tailwind CSS 3.4.1 with shadcn/ui theming system
  • Path aliases (@/) configured
  • 40+ shadcn/ui components pre-installed
  • All Radix UI dependencies included
  • Parcel configured for bundling (via .parcelrc)
  • Node 18+ compatibility (auto-detects and pins Vite version)

Step 2: Develop Your Artifact

To build the artifact, edit the generated files. See Common Development Tasks below for guidance.

Step 3: Bundle to Single HTML File

To bundle the React app into a single HTML artifact:

bash scripts/bundle-artifact.sh

This creates bundle.html - a self-contained artifact with all JavaScript, CSS, and dependencies inlined. This file can be directly shared in Agent conversations as an artifact.

Requirements: Your project must have an index.html in the root directory.

What the script does:

  • Installs bundling dependencies (parcel, @parcel/config-default, parcel-resolver-tspaths, html-inline)
  • Creates .parcelrc config with path alias support
  • Builds with Parcel (no source maps)
  • Inlines all assets into single HTML using html-inline

Step 4: Verify the Artifact

Before sharing the artifact, open the final bundle, exercise its critical interaction, and check for console errors. Add screenshots, accessibility checks, or broader browser coverage when risk-based verification requires them.

Step 5: Share Artifact with User

Share the verified bundle.html file in conversation with the user so they can view it as an artifact.
