feat: marketplace v1.1.0 - refactor to 62 focused plugins

Browse Source 
Major marketplace refactoring to optimize plugin granularity and improve
single-responsibility principle adherence, following Anthropic best practices.

Plugin Architecture Changes (36 → 62 plugins)
------------------------------------------------
Split 12 monolithic plugins into focused units:
- claude-code-essentials → code-documentation, debugging-toolkit, git-pr-workflows
- full-stack-development → backend-development, frontend-mobile-development, full-stack-orchestration
- testing-quality-suite → unit-testing, tdd-workflows, code-review-ai
- infrastructure-devops → cloud-infrastructure, kubernetes-orchestration, ci-cd-automation
- development-utilities → code-refactoring, dependency-management, error-debugging
- security-hardening → web-security, mobile-security, devsecops-practices
- data-ml-pipeline → data-engineering, machine-learning, mlops-automation
- api-development-kit → rest-api-development, graphql-development, api-security

Added 6 language-focused plugins for unused agents:
- python-development, javascript-typescript, systems-programming
- jvm-languages, web-scripting, functional-programming

New Tools (6 tools, 2,084 lines)
---------------------------------
1. test-generate.md (302 lines) - Automated unit test generation
2. component-scaffold.md (388 lines) - React/React Native scaffolding
3. xss-scan.md (307 lines) - XSS vulnerability scanner
4. python-scaffold.md (316 lines) - Python project initialization
5. typescript-scaffold.md (346 lines) - TypeScript project setup
6. rust-project.md (425 lines) - Rust project creation

Marketplace Cleanup
-------------------
- Removed 2 empty plugins (advanced-testing, docker-containerization)
- Assigned agents to 4 plugins missing them
- Validated all file references (100% valid paths)

Results
-------
- 62 plugins (was 36) - 72% increase for better granularity
- 84 agents (100% now assigned to plugins)
- 42 tools (was 36) - 16.7% increase
- Average 3.4 components per plugin (follows Anthropic 2-8 pattern)
- 100% of plugins have agents (was 94%)
- 66% of plugins have tools (was 50%)
- Version bumped to 1.1.0

This refactoring optimizes token usage, improves plugin discovery, and makes
installation more granular while maintaining the centralized file structure.

# React/React Native Component Scaffolding
You are a React component architecture expert specializing in scaffolding production-ready, accessible, and performant components. Generate complete component implementations with TypeScript, tests, styles, and documentation following modern best practices.
## Context
The user needs automated component scaffolding that creates consistent, type-safe React components with proper structure, hooks, styling, accessibility, and test coverage. Focus on reusable patterns and scalable architecture.
## Requirements
$ARGUMENTS
## Instructions
### 1. Analyze Component Requirements
```typescript
interface ComponentSpec {
name: string;
type: 'functional' | 'page' | 'layout' | 'form' | 'data-display';
props: PropDefinition[];
state?: StateDefinition[];
hooks?: string[];
styling: 'css-modules' | 'styled-components' | 'tailwind';
platform: 'web' | 'native' | 'universal';
}
interface PropDefinition {
name: string;
type: string;
required: boolean;
defaultValue?: any;
description: string;
}
class ComponentAnalyzer {
parseRequirements(input: string): ComponentSpec {
// Extract component specifications from user input
return {
name: this.extractName(input),
type: this.inferType(input),
props: this.extractProps(input),
state: this.extractState(input),
hooks: this.identifyHooks(input),
styling: this.detectStylingApproach(),
platform: this.detectPlatform()
};
}
}
```
### 2. Generate React Component
```typescript
interface GeneratorOptions {
typescript: boolean;
testing: boolean;
storybook: boolean;
accessibility: boolean;
}
class ReactComponentGenerator {
generate(spec: ComponentSpec, options: GeneratorOptions): ComponentFiles {
return {
component: this.generateComponent(spec, options),
types: options.typescript ? this.generateTypes(spec) : null,
styles: this.generateStyles(spec),
tests: options.testing ? this.generateTests(spec) : null,
stories: options.storybook ? this.generateStories(spec) : null,
index: this.generateIndex(spec)
};
}
generateComponent(spec: ComponentSpec, options: GeneratorOptions): string {
const imports = this.generateImports(spec, options);
const types = options.typescript ? this.generatePropTypes(spec) : '';
const component = this.generateComponentBody(spec, options);
const exports = this.generateExports(spec);
return `${imports}\n\n${types}\n\n${component}\n\n${exports}`;
}
generateImports(spec: ComponentSpec, options: GeneratorOptions): string {
const imports = ["import React, { useState, useEffect } from 'react';"];
if (spec.styling === 'css-modules') {
imports.push(`import styles from './${spec.name}.module.css';`);
} else if (spec.styling === 'styled-components') {
imports.push("import styled from 'styled-components';");
}
if (options.accessibility) {
imports.push("import { useA11y } from '@/hooks/useA11y';");
}
return imports.join('\n');
}
generatePropTypes(spec: ComponentSpec): string {
const props = spec.props.map(p => {
const optional = p.required ? '' : '?';
const comment = p.description ? ` /** ${p.description} */\n` : '';
return `${comment} ${p.name}${optional}: ${p.type};`;
}).join('\n');
return `export interface ${spec.name}Props {\n${props}\n}`;
}
generateComponentBody(spec: ComponentSpec, options: GeneratorOptions): string {
const propsType = options.typescript ? `: React.FC<${spec.name}Props>` : '';
const destructuredProps = spec.props.map(p => p.name).join(', ');
let body = `export const ${spec.name}${propsType} = ({ ${destructuredProps} }) => {\n`;
// Add state hooks
if (spec.state) {
body += spec.state.map(s =>
` const [${s.name}, set${this.capitalize(s.name)}] = useState${options.typescript ? `<${s.type}>` : ''}(${s.initial});\n`
).join('');
body += '\n';
}
// Add effects
if (spec.hooks?.includes('useEffect')) {
body += ` useEffect(() => {\n`;
body += ` // TODO: Add effect logic\n`;
body += ` }, [${destructuredProps}]);\n\n`;
}
// Add accessibility
if (options.accessibility) {
body += ` const a11yProps = useA11y({\n`;
body += ` role: '${this.inferAriaRole(spec.type)}',\n`;
body += ` label: ${spec.props.find(p => p.name === 'label')?.name || `'${spec.name}'`}\n`;
body += ` });\n\n`;
}
// JSX return
body += ` return (\n`;
body += this.generateJSX(spec, options);
body += ` );\n`;
body += `};`;
return body;
}
generateJSX(spec: ComponentSpec, options: GeneratorOptions): string {
const className = spec.styling === 'css-modules' ? `className={styles.${this.camelCase(spec.name)}}` : '';
const a11y = options.accessibility ? '{...a11yProps}' : '';
return ` <div ${className} ${a11y}>\n` +
` {/* TODO: Add component content */}\n` +
` </div>\n`;
}
}
```
### 3. Generate React Native Component
```typescript
class ReactNativeGenerator {
generateComponent(spec: ComponentSpec): string {
return `
import React, { useState } from 'react';
import {
View,
Text,
StyleSheet,
TouchableOpacity,
AccessibilityInfo
} from 'react-native';
interface ${spec.name}Props {
${spec.props.map(p => ` ${p.name}${p.required ? '' : '?'}: ${this.mapNativeType(p.type)};`).join('\n')}
}
export const ${spec.name}: React.FC<${spec.name}Props> = ({
${spec.props.map(p => p.name).join(',\n ')}
}) => {
return (
<View
style={styles.container}
accessible={true}
accessibilityLabel="${spec.name} component"

<Text style={styles.text}>
{/* Component content */}
</Text>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 16,
backgroundColor: '#fff',

it('meets accessibility standards', async () => {
const { container } = render(<${spec.name} {...defaultProps} />);
const results = await axe(container);
expect(results).toHaveNoViolations();

self.language = language
self.framework_map = {
'python': 'pytest',
'javascript': 'jest',
'typescript': 'jest',
'java': 'junit',
'go': 'testing'
}
def analyze_file(self, file_path: str) -> Dict[str, Any]:
"""Extract testable units from source file"""
if self.language == 'python':
return self._analyze_python(file_path)
elif self.language in ['javascript', 'typescript']:
return self._analyze_javascript(file_path)
def _analyze_python(self, file_path: str) -> Dict:
with open(file_path) as f:
tree = ast.parse(f.read())
functions = []
classes = []
for node in ast.walk(tree):
if isinstance(node, ast.FunctionDef):
functions.append({
'name': node.name,
'args': [arg.arg for arg in node.args.args],
'returns': ast.unparse(node.returns) if node.returns else None,
'decorators': [ast.unparse(d) for d in node.decorator_list],
'docstring': ast.get_docstring(node),
'complexity': self._calculate_complexity(node)
})
elif isinstance(node, ast.ClassDef):
methods = [n.name for n in node.body if isinstance(n, ast.FunctionDef)]
classes.append({
'name': node.name,
'methods': methods,
'bases': [ast.unparse(base) for base in node.bases]
})
return {'functions': functions, 'classes': classes, 'file': file_path}
```
### 2. Generate Python Tests with pytest
```python
def generate_pytest_tests(self, analysis: Dict) -> str:
"""Generate pytest test file from code analysis"""
tests = ['import pytest', 'from unittest.mock import Mock, patch', '']
module_name = Path(analysis['file']).stem

tests.append(f" result = instance.{method}()")
tests.append(f" assert result is not None\n")
return '\n'.join(tests)
```
### 3. Generate JavaScript/TypeScript Tests with Jest
```typescript

return output;
}
generateMockParams(params: string[]): string {
return params.map(p => `mock${p.charAt(0).toUpperCase() + p.slice(1)}`).join(', ');
}
}
```

expect(element).toBeVisible();
});
it('handles user interaction', () => {
render(<${componentName} />);
const button = screen.getByRole('button');
fireEvent.click(button);
expect(screen.getByText(/clicked/i)).toBeInTheDocument();
});
it('updates props correctly', () => {
const { rerender } = render(<${componentName} value="initial" />);
expect(screen.getByText('initial')).toBeInTheDocument();
rerender(<${componentName} value="updated" />);
expect(screen.getByText('updated')).toBeInTheDocument();
});
});
`;
}
```
### 5. Coverage Analysis and Gap Detection
```python
import subprocess
import json
class CoverageAnalyzer:
def analyze_coverage(self, test_command: str) -> Dict:
"""Run tests with coverage and identify gaps"""
result = subprocess.run(
[test_command, '--coverage', '--json'],
capture_output=True,
text=True
)
coverage_data = json.loads(result.stdout)
gaps = self.identify_coverage_gaps(coverage_data)
return {
'overall_coverage': coverage_data.get('totals', {}).get('percent_covered', 0),
'uncovered_lines': gaps,
'files_below_threshold': self.find_low_coverage_files(coverage_data, 80)
}
def identify_coverage_gaps(self, coverage: Dict) -> List[Dict]:
"""Find specific lines/functions without test coverage"""
gaps = []
for file_path, data in coverage.get('files', {}).items():
missing_lines = data.get('missing_lines', [])
if missing_lines:
gaps.append({
'file': file_path,
'lines': missing_lines,
'functions': data.get('excluded_lines', [])
})
return gaps
def generate_tests_for_gaps(self, gaps: List[Dict]) -> str:
"""Generate tests specifically for uncovered code"""
tests = []
for gap in gaps:
test_code = self.create_targeted_test(gap)
tests.append(test_code)
return '\n\n'.join(tests)
```
### 6. Mock Generation

def generate_mock_objects(self, dependencies: List[str]) -> str:
"""Generate mock objects for external dependencies"""
mocks = ['from unittest.mock import Mock, MagicMock, patch\n']
for dep in dependencies:
mocks.append(f"@pytest.fixture")
mocks.append(f"def mock_{dep}():")
mocks.append(f" mock = Mock(spec={dep})")
mocks.append(f" mock.method.return_value = 'mocked_result'")
mocks.append(f" return mock\n")
return '\n'.join(mocks)
```
## Output Format

### 3. Secure Coding Examples
```typescript
class SecureCodingGuide {
getSecurePattern(vulnerability: string): string {
const patterns = {
html_manipulation: `
// SECURE: Use textContent for plain text
element.textContent = userInput;
// SECURE: Sanitize HTML when needed
import DOMPurify from 'dompurify';
const clean = DOMPurify.sanitize(userInput);
element.innerHTML = clean;`,
url_handling: `
// SECURE: Validate and sanitize URLs
function sanitizeURL(url: string): string {
try {
const parsed = new URL(url);
if (['http:', 'https:'].includes(parsed.protocol)) {
return parsed.href;
}
} catch {}
return '#';
}`,
react_rendering: `
// SECURE: Sanitize before rendering
import DOMPurify from 'dompurify';
const Component = ({ html }) => (
<div dangerouslySetInnerHTML={{
__html: DOMPurify.sanitize(html)
}} />
);`
};
return patterns[vulnerability] || 'No secure pattern available';
}
}
```
### 4. Automated Scanning Integration
```bash
# ESLint with security plugin
npm install --save-dev eslint-plugin-security
eslint . --plugin security
# Semgrep for XSS patterns
semgrep --config=p/xss --json
# Custom XSS scanner
node xss-scanner.js --path=src --format=json
```
### 5. Report Generation
```typescript
class XSSReportGenerator {
generateReport(findings: XSSFinding[]): string {
const grouped = this.groupBySeverity(findings);
let report = '# XSS Vulnerability Scan Report\n\n';
report += `Total Findings: ${findings.length}\n\n`;
for (const [severity, issues] of Object.entries(grouped)) {
report += `## ${severity.toUpperCase()} (${issues.length})\n\n`;
for (const issue of issues) {
report += `- **${issue.type}**\n`;
report += ` File: ${issue.file}:${issue.line}\n`;
report += ` Fix: ${issue.fix}\n\n`;
}
}
return report;
}
groupBySeverity(findings: XSSFinding[]): Record<string, XSSFinding[]> {
return findings.reduce((acc, finding) => {
if (!acc[finding.severity]) acc[finding.severity] = [];
acc[finding.severity].push(finding);
return acc;
}, {} as Record<string, XSSFinding[]>);
}
}
```
### 6. Prevention Checklist
**HTML Manipulation**
- Never use innerHTML with user input
- Prefer textContent for text content
- Sanitize with DOMPurify before rendering HTML
- Avoid document.write entirely
**URL Handling**
- Validate all URLs before assignment
- Block javascript: and data: protocols
- Use URL constructor for validation
- Sanitize href attributes
**Event Handlers**
- Use addEventListener instead of inline handlers
- Sanitize all event handler input
- Avoid string-to-code patterns
**Framework-Specific**
- React: Sanitize before using unsafe APIs
- Vue: Prefer v-text over v-html
- Angular: Use built-in sanitization
- Avoid bypassing framework security features
