Security Prompt Templates Library

Purpose

This skill provides ready-to-use security prompt templates following the Secure Vibe Coding methodology. Each template includes complete security controls, testing checklists, and customization guidance.

When to Use This Skill

Use security prompt templates when:

• Building features: Forms, APIs, file uploads, admin panels
• Implementing auth: RBAC, permissions, ownership checks
• Security reviews: Threat modeling, code review, OWASP compliance
• Testing: Security test generation, vulnerability assessment

How to Use Security Prompts

Quick Usage Pattern

1. Identify your need (e.g., "I need a secure contact form")
2. Find the template (use triggers or browse categories)
3. Read the template to understand security controls
4. Copy and customize the prompt for your specific needs
5. Run the prompt with Claude Code
6. Verify using the testing checklist

Template Access Pattern

When a user asks for a security implementation:

**Recommend the appropriate template:**

"I'll use the [TEMPLATE_NAME] security prompt template for this.

**Template**: `.claude/skills/security/security-prompts/[category]/[file].md`

**Security Controls Applied**:
- [List controls from template]

**Customizations needed**:
- [List what to customize]

Let me load the template and customize it for your needs..."

Then read and apply the template.

Combining Prompts

Many features need multiple prompts:

Example: Admin Dashboard

1. First: auth-authorization/01_rbac_implementation.md (if RBAC not set up)
2. Then: prompt-engineering/04_admin_action.md (for each admin feature)
3. Test: prompt-engineering/08_security_testing.md
4. Review: threat-modeling/04_code_review.md
5. Update: threat-modeling/08_update_model.md

Example: User Profile Edit

1. Implement: prompt-engineering/02_authenticated_endpoint.md
2. Add ownership: auth-authorization/03_ownership.md
3. Test: auth-authorization/04_auth_testing.md

Prompt Template Format

Each template follows this structure:

# [Template Name]

**Category**: [Category]
**When to Use**: [Scenario]
**Module**: [Course module]
**Time to Implement**: [Estimate]

## Security Controls Applied
[Checklist of security features]

## The Prompt
[Copy-paste ready prompt with placeholders]

## Customization Tips
[How to adapt for specific needs]

## Testing Checklist
[Verification steps]

## Related Prompts
[Links to complementary templates]

## Version History
[Change tracking]

Integration with Security Architecture

All prompts reference the Secure Vibe Coding OS:

• Architecture: @docs/security/SECURITY_ARCHITECTURE.md
• Utilities: /lib directory (withCsrf, withRateLimit, validateRequest, etc.)
• Baseline: 90/100 OWASP score
• Stack: Next.js, Clerk, Convex, Stripe

Always include architecture reference in prompts:

Reference: @docs/security/SECURITY_ARCHITECTURE.md

Agent Usage Pattern

When security-focused agents (like security-scanner, threat-modeler) need prompt templates:

// Agent can reference specific templates
"Use the STRIDE analysis template from .claude/skills/security/security-prompts/threat-modeling/01_stride_analysis.md to create a threat model"

// Or request template by trigger
"Apply the secure form security prompt template to implement this contact form"

Skill Chaining

This skill works with other security skills:

• security-awareness/* - Understanding vulnerabilities
• csrf-protection - CSRF implementation details
• rate-limiting - Rate limiting patterns
• input-validation - Validation strategies
• auth-security - Clerk authentication
• security-testing - Testing approaches

Quick Reference by Scenario

"I need to add..."

"...a contact form" → built-in-controls/01_contact_form.md

"...user profile editing" → prompt-engineering/02_authenticated_endpoint.md → Then: auth-authorization/03_ownership.md

"...admin features" → auth-authorization/01_rbac_implementation.md (if needed) → Then: prompt-engineering/04_admin_action.md

"...file uploads" → prompt-engineering/05_file_upload.md

"...a public API" → built-in-controls/03_public_api.md

"I need to review..."

"...security before deploy" → prompt-engineering/08_security_testing.md → threat-modeling/04_code_review.md

"...OWASP compliance" → threat-modeling/06_owasp_check.md

"...payment security" → threat-modeling/07_payment_security.md

"I need to create..."

"...a threat model" → threat-modeling/01_stride_analysis.md

"...role-based access" → auth-authorization/01_rbac_implementation.md

"...security tests" → prompt-engineering/08_security_testing.md

Best Practices

Always Customize

• Replace placeholders with your specific values
• Adjust rate limits for your use case
• Modify validation rules for your data

Always Test

• Use the testing checklist in each template
• Run security tests before deploying
• Verify all controls work as expected

Always Update Threat Model

• After every feature: threat-modeling/08_update_model.md
• Maintain docs/security/THREAT_MODEL.md
• Version your threat model (v1.0, v1.1, etc.)

Chain Appropriately

• Authentication → Authorization → Ownership
• Implementation → Testing → Review
• Feature → Threat Analysis → Model Update

Example Agent Integration

# Security Implementation Agent

When implementing security features:

1. **Identify feature type** (form, API, auth, etc.)
2. **Load appropriate security-prompts skill template**
3. **Customize template** with user's specific requirements
4. **Generate secure implementation** following template
5. **Apply testing checklist** from template
6. **Recommend related prompts** for complete security

Use security-prompts skill as the authoritative source for implementation patterns.

Notes for Maintenance

When adding new security prompts:

1. Add template file to appropriate category subdirectory
2. Update category SKILL.md with new template info
3. Update this main SKILL.md quick reference
4. Add relevant trigger keywords
5. Link related prompts
6. Version the template
