Jits Builder

What This Skill Does

The Jits Builder skill, created by dannyshmueli, is a powerful utility that enables users to generate, deploy, and host custom mini-applications instantly using natural language commands. Designed for speed and efficiency, this skill utilizes the 'Just-In-Time Software' philosophy, eliminating the need for complex installation processes or bloated software environments. When a user describes a tool or utility they need, the agent automatically generates a single-file, self-contained HTML/JS/CSS application.

By leveraging Cloudflare tunnels, the skill makes these generated tools instantly accessible via a public URL, facilitating easy sharing and immediate use across different devices. It handles the backend infrastructure, including serving files via Node.js and tunnel management, so the user only focuses on the creative aspect of defining the functionality.

Installation

To integrate Jits Builder into your OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/dannyshmueli/jits-builder

Ensure that you have Node.js installed on your system. The skill will automatically attempt to handle the Cloudflared binary requirement by downloading it to /tmp/cloudflared if it is not currently detected, ensuring a smooth setup process.

Use Cases

Jits Builder is perfect for rapid prototyping and solving ad-hoc problems. It is ideal for:

• Creating quick calculators (tips, unit conversions, mortgage).
• Building productivity timers, such as Pomodoro clocks or meeting countdowns.
• Data formatting needs, such as converting CSV to JSON or cleaning up text strings.
• Generating visual utilities, like color palette pickers or simple QR code generators.
• Prototyping simple UI components for web development projects without setting up an entire build system.

Example Prompts

1. "Build me a clean Pomodoro timer that includes a sound notification after 25 minutes of focus time."
2. "I need a quick utility that allows me to paste a raw CSV block and converts it into a formatted JSON array."
3. "Create a mobile-friendly tip calculator that lets me input a bill amount and select a percentage, with a dark mode interface."

Tips & Limitations

• Guidelines: Always request single-file solutions to ensure compatibility. The apps are optimized for vanilla JS without external dependencies to maintain high performance.
• Maintenance: Use /data/clawd/skills/jits-builder/jits.sh list to monitor active tunnels and stop <name> to clear unused apps.
• Limitations: Since these are single-file apps, they cannot perform complex server-side operations. All logic must be handled client-side. The security and availability of the app depend on your local machine running the agent, as the tool uses a local Cloudflare tunnel.
