2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

πŸ”’ AUTHORIZATION & ETHICAL USE REQUIREMENTS

⚠️ CRITICAL - READ BEFORE USE ⚠️

This skill is part of a Security Practice run by a security professional with extensive experience in offensive security testing.

Legal Requirements

AUTHORIZATION IS MANDATORY:

  • βœ… ONLY test systems you own or have explicit written permission to test
  • βœ… ONLY use these techniques as part of authorized penetration testing engagements
  • βœ… ALWAYS document authorization before beginning any testing
  • βœ… RESPECT scope boundaries defined in testing agreements
  • βœ… FOLLOW responsible disclosure practices for any vulnerabilities discovered

UNAUTHORIZED TESTING IS ILLEGAL:

  • ❌ NEVER test systems without explicit written permission
  • ❌ NEVER exceed authorized scope boundaries
  • ❌ NEVER use these techniques for malicious purposes
  • ❌ NEVER disclose vulnerabilities publicly before vendor remediation
  • ❌ NEVER exfiltrate real user data during testing

Ethical Framework

This skill exists for defensive security purposes:

  1. Authorized penetration testing of client systems under formal engagement
  2. Security assessment of your own systems and products
  3. Research and education for improving AI/LLM security practices
  4. Responsible disclosure of vulnerabilities to vendors for remediation

Any use of this skill constitutes acceptance of these terms and agreement to use only for authorized, ethical security testing purposes.

  • RAG system poisoning
  • API response manipulation

Use for: Testing RAG systems, data processing pipelines

5. MultiStageAttacks

File: Workflows/MultiStageAttacks.md Triggers: "multi-stage attack", "sophisticated testing", "advanced attacks" Description: Complex multi-turn attack sequences

  • Progressive escalation
  • Context poisoning
  • Trust exploitation chains

Use for: Advanced testing, sophisticated threat simulation


Quick Start

For first assessment:

  1. Read QuickStartGuide.md (30-60 minute methodology)
  2. Verify written authorization
  3. Run Reconnaissance workflow
  4. Test top 5 attack types
  5. Document findings

For comprehensive assessment:

  1. Use CompleteAssessment workflow
  2. Follow all 9 phases
  3. Generate professional report

Resource Library

Core Documentation:

  • COMPREHENSIVE-ATTACK-TAXONOMY.md - 10 attack categories, 100+ techniques
  • APPLICATION-RECONNAISSANCE-METHODOLOGY.md - 7-phase recon process
  • DefenseMechanisms.md - Defense-in-depth strategies, remediation guidance
  • AutomatedTestingTools.md - Promptfoo, Garak, PyRIT comparison
  • QuickStartGuide.md - First assessment checklist (30-60 min)
  • Reporting.md - Report structure, templates, presentation guidance

All resources are in the PromptInjection skill root directory.


Key Principles

Authorization-First

  1. Written authorization is mandatory
  2. Document everything (scope, boundaries, approvals)
  3. Respect boundaries - in-scope only
  4. Stop if uncertain - clarify before proceeding

Methodical Testing

  1. Systematic approach - follow established methodology
  2. Document as you go - record all tests and results
  3. Reproduce findings - ensure vulnerabilities are reliable
  4. Assess impact accurately - distinguish theoretical vs practical risk

Responsible Disclosure

  1. Give vendors time - 90-day disclosure timeline typical
  2. Clear communication - detailed reproduction steps
  3. Coordinate disclosure - work with vendor on timing
  4. Protect users - no public details before patch

Examples

Example 1: Quick test

User: "test this chatbot for prompt injection - I own it"
β†’ Verifies authorization
β†’ Runs Reconnaissance workflow
β†’ Tests top 5 attack types
β†’ Documents findings

Example 2: Full assessment

User: "comprehensive prompt injection assessment for client"
β†’ Loads CompleteAssessment workflow
β†’ 9-phase methodology (12-20 hours)
β†’ Professional report with remediation

Example 3: Research

User: "what are the latest jailbreaking methods?"
β†’ Searches COMPREHENSIVE-ATTACK-TAXONOMY.md
β†’ Returns categorized techniques with effectiveness ratings

Support & Escalation

When to escalate:

  • Authorization is unclear or questionable
  • Ethical concerns arise
  • Novel attack techniques discovered
  • Critical 0-day vulnerabilities found

Contact:

  • Configure in your USER settings

πŸ”’ REMINDER: AUTHORIZED USE ONLY πŸ”’

This skill contains powerful security testing techniques. Use only for:

  • βœ… Systems you own
  • βœ… Systems with explicit written authorization
  • βœ… Ethical security research
  • βœ… Defensive security purposes

Unauthorized use is illegal and unethical.
