- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### JITS Builder - Just-In-Time Software 🚀

Build instant mini-apps from voice or text descriptions. Describe what you need, get a working tool deployed in seconds.

### What is JITS?

Just-In-Time Software - the idea that you don't need to find or install tools. You describe what you need and it gets built on the spot.

"I need a timer that plays a sound after 25 minutes"
"Make me a tool to split a bill between friends"
"Create a page where I can paste JSON and see it formatted"

### Requirements

Cloudflared binary (auto-downloads to /tmp/cloudflared if missing)
Node.js (for serving the app)

### How It Works

Describe - Voice or text, explain what you want
Generate - Agent builds a single-file HTML/JS/CSS app
Deploy - Cloudflare tunnel makes it instantly accessible
Use - Get a URL, use your tool, share it

### Usage

Just ask naturally:

"Build me a pomodoro timer"
"I need a quick tool to convert CSV to JSON"
"Make a tip calculator"
"Create a color palette generator"

The agent will:

Generate the HTML/JS code
Save to /data/clawd/jits-apps/<name>.html
Serve on a local port
Create Cloudflare tunnel
Return the public URL

### Managing JITS Apps

# List running apps
/data/clawd/skills/jits-builder/jits.sh list

# Stop an app
/data/clawd/skills/jits-builder/jits.sh stop <name>

### App Guidelines

When building JITS apps:

Single file - All HTML, CSS, JS in one file
No dependencies - Use vanilla JS, no external libraries
Mobile-friendly - Responsive design
Dark theme - Looks good, easy on eyes
Self-contained - No backend/API calls needed
Branded - Include "Built with JITS" badge

### Limitations

Single-page only - No multi-page apps
No backend - Client-side only, no databases
Temporary URLs - Tunnels expire when stopped
No persistence - Data doesn't survive refresh (use localStorage if needed)
