Agent Creation Workflow
When creating new specialized agents:
1. Create the Agent File
- Location: Always create new agents in
cli-tool/components/agents/ - Naming: Use kebab-case:
frontend-security.md - Format: YAML frontmatter + Markdown content
2. File Creation Process
# Create the agent file
/cli-tool/components/agents/frontend-security.md
3. Required YAML Frontmatter Structure
---
name: frontend-security
description: Use this agent when securing frontend applications. Specializes in XSS prevention, CSP implementation, and secure authentication flows. Examples: <example>Context: User needs to secure React app user: 'My React app is vulnerable to XSS attacks' assistant: 'I'll use the frontend-security agent to analyze and implement XSS protections' <commentary>Frontend security issues require specialized expertise</commentary></example>
color: red
---
Required Frontmatter Fields:
name: Unique identifier (kebab-case, matches filename)description: Clear description with 2-3 usage examples in specific formatcolor: Display color (red, green, blue, yellow, magenta, cyan, white, gray)
4. Agent Content Structure
You are a Frontend Security specialist focusing on web application security vulnerabilities and protection mechanisms.
Your core expertise areas:
- **XSS Prevention**: Input sanitization, Content Security Policy, secure templating
- **Authentication Security**: JWT handling, session management, OAuth flows
- **Data Protection**: Secure storage, encryption, API security
## When to Use This Agent
Use this agent for:
- XSS and injection attack prevention
- Authentication and authorization security
- Frontend data protection strategies
## Security Implementation Examples
### XSS Prevention
```javascript
// Secure input handling
import DOMPurify from 'dompurify';
const sanitizeInput = (userInput) => {
return DOMPurify.sanitize(userInput, {
ALLOWED_TAGS: ['b', 'i', 'em', 'strong'],
ALLOWED_ATTR: []
});
};
Always provide specific, actionable security recommendations with code examples.
### 5. Installation Command Result
After creating the agent, users can install it with:
```bash
npx claude-code-templates@latest --agent="frontend-security" --yes
This will:
- Read from
cli-tool/components/agents/frontend-security.md - Copy the agent to the user's
.claude/agents/directory - Enable the agent for Claude Code usage
6. Usage in Claude Code
Users can then invoke the agent in conversations:
- Claude Code will automatically suggest this agent for frontend security questions
- Users can reference it explicitly when needed
7. Testing Workflow
- Create the agent file in correct location with proper frontmatter
- Test the installation command
- Verify the agent works in Claude Code context
- Test agent selection with various prompts
- Ensure expertise boundaries are clear
8. Example Creation
