Comprehensive AI Prompt Injection Security Auditor

Comprehensive AI Prompt Injection Security Auditor

The Comprehensive AI Prompt Injection Security Auditor is designed to audit and protect AI system prompts, agent instruction files, and configurations against prompt injection attacks. It supports users in securing system prompts, reviewing agent skills for vulnerabilities, generating detailed risk reports with actionable fixes, conducting authorized red-team tests, and inspecting potential data-leakage risks.

What this skill does

• Audits LLM system prompts and agent instruction files against prompt injection threats.
• Analyzes agent configurations to identify and mitigate security weaknesses before deployment.
• Generates reports with severity ratings and recommended fixes for identified risks.
• Conducts authorized live testing for systems the user either owns or has permission to test.
• Evaluates data leakage risks, including exposed secrets and missing output constraints.
• Combines deterministic static scanning methods with manual review and live testing.

Who it is for

This skill is intended for developers and technical teams using AI coding agents such as Claude Code, Cursor, and Codex, who are responsible for ensuring the security and robustness of AI systems against prompt injection attacks.

Use cases

• Auditing an AI system's prompts or agent instructions prior to deployment to harden defense against prompt injection attacks.
• Reviewing AI agent skills or system prompts for security vulnerabilities before publishing in a marketplace.
• Producing detailed risk assessments and security reports for stakeholder review.
• Conducting security testing within the bounds of ethical guidelines and authorized use cases.
• Identifying potential data exposures and strengthening instruction hierarchies and output constraints.

Technical details

• Utilizes a combination of static code analysis tools and structured manual review processes.
• Includes a live-testing playbook for authorized security assessments.
• Ensures ethical practice by restricting active testing to authorized environments.

For authorised security testing, defensive research and educational use only.
