What this skill does


# Web Development Guidelines

You are an expert in web development with knowledge of various frameworks and best practices.

## Bootstrap Development

### Core Principles
- Use Bootstrap's grid system for responsive layouts
- Leverage utility classes for rapid styling
- Customize through Sass variables
- Follow mobile-first approach

### Grid System
```html
<div class="container">
  <div class="row">
    <div class="col-12 col-md-6 col-lg-4">Column 1</div>
    <div class="col-12 col-md-6 col-lg-4">Column 2</div>
    <div class="col-12 col-md-12 col-lg-4">Column 3</div>
  </div>
</div>
```

### Components
- Use pre-built components (navbar, cards, modals)
- Customize with utility classes
- Ensure accessibility attributes
- Test responsive behavior

### Customization
```scss
// Custom variables
$primary: #0d6efd;
$font-family-base: 'Inter', sans-serif;

// Import Bootstrap
@import "bootstrap/scss/bootstrap";
```

## Django Development

### Project Structure
```
project/
├── apps/
│   ├── core/
│   ├── users/
│   └── api/
├── config/
│   ├── settings/
│   ├── urls.py
│   └── wsgi.py
├── static/
├── templates/
└── manage.py
```

### Views
```python
from django.views.generic import ListView, DetailView
from django.shortcuts import render, get_object_or_404

class ArticleListView(ListView):
    model = Article
    template_name = 'articles/list.html'
    context_object_name = 'articles'
    paginate_by = 10

def article_detail(request, slug):
    article = get_object_or_404(Article, slug=slug)
    return render(request, 'articles/detail.html', {'article': article})
```

### Models
```python
from django.db import models

class Article(models.Model):
    title = models.CharField(max_length=200)
    slug = models.SlugField(unique=True)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        ordering = ['-created_at']

    def __str__(self):
        return self.title
```

### Forms
```python
from django import forms

class ContactForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    message = forms.CharField(widget=forms.Textarea)

    def clean_email(self):
        email = self.cleaned_data['email']
        # Custom validation
        return email
```

## HTMX Development

### Core Concepts
- Use hx-get, hx-post for AJAX requests
- Update DOM with hx-target and hx-swap
- Trigger events with hx-trigger
- Handle loading states with indicators

### Basic Usage
```html
<!-- Load content on click -->
<button hx-get="/api/data" hx-target="#results">
  Load Data
</button>
<div id="results"></div>

<!-- Form submission -->
<form hx-post="/api/submit" hx-target="#response">
  <input type="text" name="query">
  <button type="submit">Submit</button>
</form>
<div id="response"></div>
```

### Triggers
```html
<!-- Trigger on different events -->
<input hx-get="/search" hx-trigger="keyup changed delay:500ms" hx-target="#results">

<!-- Trigger on page load -->
<div hx-get="/initial-data" hx-trigger="load"></div>

<!-- Trigger on intersection -->
<div hx-get="/more" hx-trigger="intersect once"></div>
```

### Swap Options
```html
<!-- Different swap strategies -->
<div hx-get="/content" hx-swap="innerHTML">Replace inner</div>
<div hx-get="/content" hx-swap="outerHTML">Replace entire element</div>
<div hx-get="/content" hx-swap="beforeend">Append</div>
<div hx-get="/content" hx-swap="afterbegin">Prepend</div>
```

### Loading States
```html
<button hx-get="/data" hx-indicator="#spinner">
  Load
  <img id="spinner" class="htmx-indicator" src="/spinner.gif">
</button>
```

## General Best Practices

### Performance
- Minimize HTTP requests
- Optimize images and assets
- Use caching strategies
- Implement lazy loading
- Minify CSS and JavaScript

### Security
- Validate all user inputs
- Use CSRF protection
- Implement proper authentication
- Sanitize output to prevent XSS
- Use HTTPS

### Accessibility
- Use semantic HTML
- Provide alt text for images
- Ensure keyboard navigation
- Maintain color contrast
- Test with screen readers

### SEO
- Use proper heading hierarchy
- Add meta descriptions
- Implement structured data
- Create XML sitemaps
- Optimize page speed

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

Backend & APIsscripts

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
